Adding Value to Industry
World Class Cutting Tools
Founded in 1917, Sutton Tools began as a family enterprise, manufacturing threads and gauges, and over time has expanded its expertise into a broader portfolio of cutting tools. Today, Sutton Tools remains an Australian family business that is renowned for its high-quality power tool accessories and cutting tools for the hardware market and a wide range of specialised industrial applications.
Sutton Tools manufactures cutting tools at three sites across Victoria, both for the domestic market and for export. The bulk of general production occurs at our head office site at Thomastown, in Melbourne’s northern suburbs, with more specialised operations centred at our Maryborough facility. We also have overseas production plants in Auckland, New Zealand, and in the Netherlands.
Sutton Tool’s state-of-the-art production processes begin with raw material preparation. High-speed steel is imported from France and Switzerland in 3.5m-length bars, as Sutton Tools has found the quality of this European-manufactured steel is superior to raw material sourced from Asia. This steel is cut to length and turned, using computer controlled machines that are able to complete a number of turning operations in a single manufacturing stage.
While Sutton Tools supplies tools to a broad spectrum of industriesincluding general manufacturing, electronic manufacturing, automotive, medical, mining and power generation - most advancement in material technology it experiences are occurring in the aerospace, defence and oil/gas industries. The development of so-called ‘super alloys’ for these sectors is constantly pushing material performance boundaries. However, the tougher these materials become, the tougher the tools need to be to work the new generation of alloys.
The good news for tradies and DIY enthusiasts is that the cutting technologies developed for these state-of-the-art cutting applications filter through to the tools Sutton produces for the hardware industry. All of Sutton’s tools are manufactured from high-speed steel and are ground-from-solid, regardless of whether they are destined for the hardware market or for a specialised industrial application. In the same way that a car manufacturer utilises technologies developed through motorsport to improve the reliability and performance of the family cars it produces, so Sutton Tools is able to use its specialised industrial experience to deliver optimised tools for the hardware market.
We've made it easier to find the right tool fast...
For easy tool reference, you will find an extensive application based index at the start of each section.
These icons below can be found on the product pages throughout the catalogue, and at a glance the characteristic features of the tool can be identified.
We have been manufacturing quality cutting tools in Australia since 1917 and the fact that we are manufacturing in Australia is becoming an important part of our message.

1917 - the start to an iconic Australian family brand, manufacturing cutting tools for distribution throughout Australia...
William Henry Sutton arrived in Australia
William Henry Sutton, a British Immigrant, opened a tool room at Thompson’s Foundry at Castlemaine. He was recognised as one of the leading tool engineers in England before his departure to Australia.
Patience and Nicholson (P&N®) in Australia
The P&N ® brand was founded, providing cutting tools for the professional and serious DIYer in Australia.
Start to an iconic Australian family brand
Nearing the end of World War 1 in 1917 after been seconded back to the UK to help with the war effort, W. Henry Sutton at the age of 54, established the Sutton Tool & Gauge Manufacturing Co. at Plant Street Westgarth, Victoria.
Thread production
Sutton Tool & Gauge commenced the manufacture of Thread Tooling, expanding its product portfolio.
Business quadrupled
It soon became evident to local manufacturers’ they could now buy domestically produced tools of equal or better quality than those from overseas! With the original factory ‘bursting at the seams’, Sutton Tool & Gauge moved to a 13,000 square foot factory in Northcote, Melbourne.
A broader market goal
The next generation
Both sons of W. Henry, Henry George Sutton and Leslie Sutton became managing directors of the business whilst William Henry at age 77 continued to take an active interest.
Sutton Tool & Gauge first export was to New Zealand, a consignment of reamers.
Frost (Tools) Engineering
Frost started manufacture, sourcing and supplying hand tools and power tool accessories in Australia.
William Henry Sutton
Our History. Our Tradition.
Ground-from-Solid
Industry Legend
William Henry Sutton, born 1863 - died 1950, a highly regarded tool and gauge engineer prior to the founding business owner of Sutton Tool & Gauge. William was a pioneer of the Australian Engineering Industry.
A team of engineers were sent across the globe to investigate the best method of producing the finest drill in the world. They came back with the “Ground-from-Solid” process. All endmills, slot drills and taps up to ½" diameter were produced by this method. Sutton Tools purchased and installed specialised equipment and was considered to have one of the most modern facilities in the world.
Increasing demand
The demand for high quality tools made by Sutton’s continued, and to meet with increasing sales the firm opened another 45,000 square foot factory in Thomastown.
Manufacturing of
Jobber Drills
Sutton Tool & Gauge commenced manufacturing Jobber Drills in Thomastown.
Third generation
Sutton Tool & Gauge acquired an adjoining factory in Thomastown.
The third generation Suttons, Bill and Jim, consolidated and extended Sutton Tools’ position in the market, through their absolute commitment to quality, innovation and persistence.
Surface Technology Coatings
Sutton Tools established Surface Technology Coatings and for the first time could offer physical vapour deposition (PVD) coatings on their products. Previously any coated tools sold in Australia were imported.
Company name changed to Sutton Tools
With the expansion into a greater range of products the company officially changed its name from ‘Sutton Tool & Gauge’ to ‘Sutton Tools’.
4th Generation
During the 1990’s Peter and Robert Sutton joined the family business. Their combined experience and passion in cutting tools has positioned Sutton Tools as an Australian champion in manufacturing.

Sutton Tools Code System – explained
Sutton Tools item # system makes it easier to identify a product. The codes are based on a universal prefix and suffix system.
Prefix (Catalogue Code) – is alpha numeric, and is unique to a specific product range. The letter is relevant to the type of tool, and the number refers to a product range.
C - Countersinks
D - Drills
E - Endmills
L - Literature
R - Reamers
T - Taps
Z - Tool Holders / Chucks
Suffix (Size Ref.) – in most cases is relevant to the diameter or size reference of an item and is based on a metric value.
For example 5mm = 0500, and 1/4" = 0635 (inch converted to decimal).
Suffix can also refer to set code or number of pieces in a set.

7 Partial or complete tap breakage on FORWARD or BACKWARD movement
1 2 3 4 5 6 7 Possible reason
•
•
• •
• Wrong tap, cutting geometry of the tap is not suitable for this operation
• • Tap hole diameter is undersize
• Misalignment - tap hole position, or angle is not correct
• The axial machine spindle movement is not free and easy
• Cold welding on the thread flanks of the tap
• Poor guidance of the tap because of little thread depth
•
•
•
• • Speed is too high
• • Chip clogging
• • The lubrication wrong, additives or the coolant supply is not sufficient
• Spiral fluted taps are over pressured in the initial cutting phase (retracting pulling force)
• Spiral pointed taps (gun taps) are not receiving enough pressure in the initial cutting phase
• •
•
Tolerance on the tap is not identical to the tolerance on the drawing or on the gauge
Wrong initial cutting pressure has been used or the machine spindle is not moving along its axis free and easy
• • Tap is over loaded, either from coarse pitch and/or tough material
• Cold welding, material build-up (pick-up)
• • Hardened walls in drilled hole
• Over loading of teeth in the chamfer area
Solution
Use correct tap for the material group (see Expert Tool System, at www.suttontools.com)
Tap hole diameter should be in accordance to DIN336 or respective standard. For cold forming taps, a special hole diameter is needed.
a) check workpiece clamping
b) check machine settings
a) use mechanical feed
b) use tap holder with length compensation
a) use a new tap
b) improve and check lubrication
c) remove cold welding area from tap
d) use tap with surface treatment or coatings
a) use mechanical feed
b) use tap that has better guiding characteristics
a) improve lubrication
b) lower speed
a) use tap with different flute form
b) use coated taps
c) use tap set
Make sure that the coolant is correct and that the supply is sufficient
Spiral fluted taps should only be lightly pushed into the tap hole until it begins to cut. The tap holder should immediately begin to apply tension to the tap.
Spiral pointed taps and even left hand spiral flute taps must have a stronger pressure until they begin to cut. The tap holder should immediately begin to apply pressure to the tap (pushing force)
Use a tap which has a correct tolerance
a) use mechanical feed
b) use tap holder with length compensation
Use set of taps
a) improve coolant supply, use taps with surface treatments or coatings
b) check if surface treatment is correct for this application
a) use drill best suited to material being drilled
b) use new drill or boring tool
c) resharpen drilling or boring tools
d) if possible, heat treatment and coatings should only be made after threading
a) use a longer chamfer (check if the tap hole is blind hole or through)
b) use increased number of teeth in the chamfer area by selecting tap with increased number of flutes
• Tap hole chamfer is missing or wrong Countersink tap hole chamfer with correct angle
• Tap crashed against the bottom of tap hole
Use tap holder with length compensation and over load clutch

Description
Used for the manufacturing of cutting tools such as twist drills, endmills and taps.
Cobalt alloyed, tungsten-molybdenum high speed steel possessing high hardness, excellent cutting properties, high-red hardness and good toughness.
Available for applications that require a strong resistance to softening at elevated cutting temperatures. The ability of the steel to maintain its “red-hot hardness” is provided by the addition of cobalt. The high hot hardness is required for machining difficult materials such as nickel-base, titanium and highly alloyed steel.
Vanadium grade gives high wear resistance and toughness for most tapping applications.
PM-HSS V3 for higher performance tools, incorporates very fine and uniform grain structure allowing a high hardness to be achieved, whilst maintaining good toughness.
The addition of cobalt provides this material with the ability to maintain its strength and hardness level when exposed to extremely high cutting temperatures. This makes PM-HSS Co suitable for heavy duty tapping, in materials such as high alloyed steels to non-ferrous metals like Ni-base alloys & Ti-alloys.
An excellent bridge material between high speed steel and carbide. SPM offers very high red hardness, wear resistance and the highest compressive strength of any high speed steel.
Ultra fine grain type (0.8µm) with maximum toughness & high hardness, therefore especially recommended for rotating tools to machine hardened parts.
Ultra fine grain type (0.6µm) offers the ideal combination of hardness & toughness for high performance drilling & general milling applications
Ultra fine grain type (0.5µm) offers the best wear resistance for high performance milling applications.
Computer controlled vacuum heat treatment ensures consistent high quality

Technical Information Fluteless Taps
Fluteless taps
Fluteless taps do not cut threads in the same manner as conventional taps – but actually FORM and FLOW the threads with an absence of chips. Used under suitable conditions, these taps produce threads with a high degree of finish not possible with ordinary taps. Ductile materials are most appropriate for forming of threads and must have a minimum 10% elongation.
Benefits of thread forming
Higher speeds and tool life
Reduced possibility of breakage due to no cutting edges and robust tool construction
Figure 1. No chips produced
Figure 2. Higher tensile strength threads produced due to grain structure following the thread form
Figure 3. For use in through and blind holes applications
Suitable for wide range materials
-Low carbon steels
-Leaded steels
-Austenitic stainless steels
-Alloy steels; typically up to 1200 N/mm2, (36 Rc) with a minimum 10% elongation

-Wrought aluminium alloys (Ductile)
-Zinc die casting alloys
-Copper and copper alloys
Because the thread produced by a fluteless tap is substantially stronger than a conventional thread, greater tool life and efficiency may be obtained when forming up to 65% thread. Threads may be formed up to 80% of depth, but tool life will be reduced and work clamping pressure necessarily increased. Greater tapping speeds allow the metal to flow far more readily, so 60 feet per minute minimum may be used as a guide, but this could increase with the type of material being tapped. A depth of 65% is recommended for the ductile materials mentioned, but this percentage will be reduced for less ductile materials to maintain all-round efficiency.
Tapping drill formula for fluteless taps
Refer Tapping Drill Size Chart for recommended sizes (Suitable for Unified, Whitworth and Metric sizes only). The formula to calculate the theoretical hole size for a required percentage of thread is:
It is to be noted that the drill size for fluteless tapping is always larger than the P.D. of the thread. A drill size equal to the P.D. of the thread would produce 100% of thread, but this is NOT recommended.
As the additional driving torque is only up to 50% increase, any conventional driving equipment using the square as a drive is suitable for fluteless tapping
Lubrication
In general it is best to use a good cutting oil or lubricant rather than a coolant for fluteless tapping. Sulphur base and mineral oils, along with most friction reducing lubricants recommended for use in cold extrusion or metal drawing, have proven best for this work. Make sure lubricant is clean, free from chips swarf and filings in suspension, which produce a poor finish and jamming, sometimes breakage – extra filtration may be required.
Countersinking
Because the fluteless tap displaces metal, some metal will be displaced above the mouth of the hole during tapping, countersink or chamfer the hole prior to tapping will reduce the extrusion within the countersink and not interfere with the mating part.
Formed Thread Cut Thread
Formula Example
Drill size = nominal thread dia. (in mm)– (0.007 x % of thread x pitch)
Drill size for 65% of thread in a M6 x 1.0 threaded hole would be: Drill size = 6 – (0.007 x 65 x 1.0 (pitch)) = 5.54mm (Use 5.50mm drill (Stockable drill) = 71%)
