Overview of different standard HW grades

The sharpest knives in the world: sharpening transverse to the cutting edge.

• freud custom grinding methods reach the minimum possible roughness level of the cutting edge (µm 0.12 to 0.15), for a finish quality on wood and derivates unmatched on the market.

• The cutting edge is so sharp to better withstand the cutting pressure for maximum abrasion resistance and thus unbeatable lifetime.

freud - the sharpest cutting edges

Committed to the finest quality: ongoing investments in manufacturing.

• Superior tool wear resistance: every process, from raw material selection to final grinding, is designed with the highest technological standards.

• Pioneering testing methods: freud strict control over the manufacturing process ensures 100% compliance to the quality parameters.

Advice for the correct use of the tools

Marking of the maximum free shank length

To reduce vibrations from the router cutter, which can compromise the finish and cause damage to both the tool and the workpiece, it is necessary to respect the following conditions: • For large removals, carry out more passes or procede with an advancement and RPM rate in proportion to the depth of cut (Fig. 1).

• A router bit with a shorter cutting height vibrates less than a router bit with the same diameter but with a longer cutting height.

• Control your machine regularly, making sure that there are no eccentricity problems, so as to avoid the arbor from vibrating hazardously.

• Respect the minimum fixing length of the shank (Fig. 2) with a preference to short chucks, with the aim of reducing eccentricity errors. For the same reason the use of extensions are generally avoided.

• Accurately block the workpiece to the work table surface (Fig. 3).

• To identify eccentricity defects in a router bit or a chuck: rotate the router bit by 90° in the chuck, carry out a moulding and observe the marks left on the workpiece. If they are invaried with respect to the previous moulding, then the tool is defective, if instead the marks vary, then it is possible that the error lies in the chuck.

• Do not exceed the maximum RPM limit marked on the tool. With too high an advancement rate, or an excessive cutting depth, there is the possibility that the tool may break (especially spiral router bits).

• To avoid damaging router bits, we suggest controlling if the fixing surface of the chuck and the router bit are clean and that there are no imperfections.

• Always choose router bits with the appropriate dimensions for the kind of work to carry out.

• To avoid dangerous kick backs, we suggest fixing a spare piece of material and moulding small parts of waste which have accumulated during the working process, by carrying out more passes (Fig. 4 - 5).

• Make sure that the workpiece is properly fixed to a support with adequate dimensions. In the case of all router bits, but especially those with tips in PCD for overhead CNC router machines, it is necessary to fix the piece properly, preparing an abundant space when blocking by means of vacuum.

Cutting quality

Performance Testing: A router bit’s performance depends on two main factors; it is cutting quality and it is life span. We performed comparison tests on freud router bits, with particular focus on cutting life and finish.

Straight router bits with identical dimensions (cutting diameter 1/2”, shank diameter 1/2”, 2 flute) were mounted on a CNC router.

We then routered a number of 1/4” deep grooves on a chipboardmelamine coated panel.

The final evaluation was based on the number of chips on the melamine coating and averaging the first and the last 33 routed feet.

Initially, all router bits performed in a similar way but as the number of routed feet increased, freud router bit performed superior to the other bits (please refer to the graphically represented test results below for more details and information). freud has a complete range of bits that offer high quality, long working life and less friction when cutting.

Perma-SHIELD Coating Each bit features high grade steel, TiCo Hi-Density Carbide Tips, and the exclusive red Perma-SHIELD coating. Perma-SHIELD coating reduces friction and heat build up, helps prevent the adhesion of resins, and protects the bit from corrosion.

Computer Designed Hook Angles The accuracy of the hook angle ensures that the bit provides a premium top cutting finish and the inclination of the clearance angle on the tip’s bottom allows easy and precise boring.

Unique Carbide Formulations Maximized finish and lifetime in each application Using the correct carbide formulation for each application is extremely important when it comes to maximising a router bit’s performance. For example, an extremely hard carbide formulation is required to maintain a sharp edge when cutting laminate. Alternately, a softer carbide or impact resistant carbide is ideal for large profile cutting such as Panel Bits (Fig. 1).

Others Use the Same Carbide For all Applications Most manufacturers create router bits with standard off-the-shelf carbide, which is not specifically designed for wood cutting applications. These carbides will not be able to maintain the proper tooth geometry or sharp edge. After a few hours of use, these standard carbides might not show imperfections; however, without the proper carbide formulation, material finish and cutting life will suffer (Fig. 2).

Superior TiCo Hi-Density Carbide Provides Longer Cutting Life freud’s premium quality TiCo hi-density carbide allows for a sharper edge that gives a better finish with a dramatically longer cutting life.

And, since the grains are much smaller and more dense there is not as dramatic a loss to the cutting edge, so wear occurs much more slowly (Fig. 3).

Standard Off The Shelf Carbide Most manufacturers create router bits with standard off-the-shelf carbide, which is normally formulated for metal cutting. These carbides will not be able to maintain the proper sharp edge. After a few cuts, these standard carbides might not show imperfections; however, without the proper carbide formulation, material finish and cutting life will suffer (Fig. 4).

Kickback-Reducing Design Promotes Safety Kickbacks are one of the most dangerous hazards in woodworking. This happens so quickly that it can be impossible to react before injury occurs. freud’s kickback-reducing shoulder design restricts the tooth bite to 1.1 mm, reducing the effects of kickback from overfeeding. This design contributes to a safer working environment.

Standard Router Bit Designs Prone to Dangerous Kick-Backs Standard router bit designs do not include a kickback reducing shoulder. The bits do not have extra support behind the cutting flute. This limitation allows the bit to take large bites out of the material and produces uncontrolled, rough cuts particularly when operating at lower speeds.

Computer Balancing Prevents Chattering and Vibration All freud router bits are computer balanced to ensure vibration free cuts. The balancing takes place on special computer controlled equipment that determines the exact location where material needs to be removed. After material removal, the equipment re-checks the router bit to ensure the bit is perfectly balanced.

Uncontrolled Cut

Ro

ta

tio

Unbalanced Router Bits Cause Chattering and Vibration A router bit that is even slightly out of balance will vibrate and chatter while cutting, and it can be extremely dangerous if it is far out of balance. An unbalanced router bit can also create unnecessary rework costing quality of work, time and money.

Shear Angle Design Produces Superior Finish The shear angle is the angle that the cutting edge makes with the shank of the bit. freud carbide tips are angled to slice through the wood fibers similar in principle to using a hand plane at an angle to the direction of the motion. This slicing action becomes even more important when cutting across the grain. freud’s high shear angle bits leave a cross grain cut that requires virtually no sanding.

n

Standard Router Bits Have Little or No Shear Angle Bits without shear or with too little shear chop the wood and are more likely to produce tear out and chatter marks. In addition, not having the proper shear angle causes premature wearing of the carbide and puts more strain on the router.

Technical information

Gullet The cut out area in the body in front of each carbide tip for chip removal.

Hook Angle The angle the face of the carbide tip makes with a line projecting radially from the center of the shank.

Relief Angle The angle the tip of the carbide tooth makes away from the cutting edge to a line tangent to the bit circumference.

Shear Angle The angle that the cutting edge makes with a line parallel to the shank of the bit.

Shank The precision ground, cylindrical part of the bit that is held in the router collet.

Solid Carbide Bit A router bit formed entirely of carbide, including the shank, body and cutting edge.

Found primarily in small diameter and spiral router bits.

Anti-Kickback Limiter The projection at the front of the gullet which limits the maximum tooth bite to the safe limit for the bit design reducing the effects of kickback.

Brazing The method used to attach the carbide tips to the blade body. Both the blade and the body are heated above the melting point of the brazing compound, which then flows, by capillary action into the joint, forming a bond between the parts.

Pilot Bearing The part of the bit designed to guide the bit and control the depth of cut. Often used to rout the edges of irregularly shaped objects and for following templates.

duce decorative, fluted grooves.

Flush Trim (Pattern) Bits Straight cutting bits that include a pilot bearing that is the same diameter as the cutter.

Often used for laminate work and template routing.

Spiral Bits Special straight cutting bits that are formed with helical flutes for more efficient chip ejection. The helical shape of the flutes also results in shear angles that produce a smoother surface finish.

Compression Bits Straight cutting bits that combine both down shear angles and up shear angles for excellent finish on both the top and bottom of the cut.

Raised Panel Bits Produce a decorative profile on the edge of a wood panel while reducing the edge thickness to fit into the groove of a stile and rail frame.

Back Cutters Secondary cutters used in combination with raised panel bits to create double-sided panels that are in the same plane with both the front and back of the stile and rail frame.

Rail And Stile Bits Used to produce frames for panel doors. The stile or stick cut refers to the profiled inner edge of the frame and either a groove to accept a panel or a rebate for glass. The rail or cope cut is the mating glue joint produced on the ends ofthe rails.

Repair shall therefore include, e.g. use of spare parts which are in accordance with the specification of the original parts provided by the manufacturer.

Tolerances which ensure correct clamping shall be maintained.

For one piece tools care shall be taken that regrinding of the cutting edge will not cause weakening of the hub and the connection of the cutting edge to the hub.

To avoid injuries, tools shall be handled in accordance with the guidance provided by the manufacturer. Typically, safe handling involves the use of devices such as carrying hooks, proprietary handles, frames (e. g. for circular saw blades), boxes, trolleys etc.

The wearing of protective gloves improves the grip on the tool and further reduces the risk of injury.

Maintenance and modification of milling tools and related components and circular saw blades should always be in accordance with the design requirements/the manufacturer’s instructions.

Maintenance and modification of milling tools and circular saw blades should only be carried out by a competent person, i. e. a person of training and experience, who has knowledge of the design requirements and understand levels of safety to be achieved.

When regrinding milling tools and circular saw blades, the minimum requirements of cutting blade thickness and cutting blade projection should be observed.

Composite tools should be repaired by persons experienced in and with understanding of design and use of milling tools for processing wood and similar materials, e.g. an expert with a relevant education and knowledge of the brazing process, including in particular the influence of the brazing process on tension in tool

170

body and cutting material. When brazing off worn tips and subsequently brazing on new tips it should be made sure that the tip is correctly mounted in the tool body and that the process does not result in critical tension in the tool body.

After any type of maintenance, milling tools marked with MAN should continue to observe the requirements of the standards related to tools for hand feed.

When modifying milling tools, e. g. modification of bore diameter, modification of shank, retipping of composite tools and similar, it should be ensured that the requirements of the standard relating to balancing are still observed.

After being modified and/or retipped, milling tools and circular saw blades should be marked according to the rules applying to new tools. However, the name/logo of the company making the modification/retipping should be added.

To avoid injuries, tools shall be handled in accordance with the guidance provided by the manufacturer.

Tools which weigh more than 15 kg may require the use of special handling devices or attachments, these will depend on the features that the manufacturer has designed into the tool to allow easy handling. The manufacturer can advise on the availability of necessary devices.

CLAMPING DEVICES The speeds indicated on the clamping device and the tool to be clamped should be compared. For adjusting the speed on the machine the lower speed should be applied.

Screws and nuts should be tightened using the appropriate spanners; Clamping surfaces should be cleaned to remove dirt, grease, oil and water; Clamping devices and tools should be mounted or clamped according to given torques, pressures and wrenches to be used; extension of spanners or tightening or loosening by means of hammer blows should not be permitted; Maximum tool diameters and tool lengths should not be exceeded; Shank diameters must be in accordance with the clamping range of the clamping devices; The minimum required clamping length must be kept; Care should be taken that the data relevant to the safety of the clamped tool are always stored in the data medium.

Repairs should only be carried out by a competent person, i.e. a person with professional training and experience, who has knowledge of the design, construction and safety requirements; Repair should therefore include the use of spare parts which are in compliance with the specifications of the original parts.
