5 flute Trochoidal end mills with variable helix The SCT 5 flute Trochoidal end mills combine a few unique characteristics to make them ideally suited for machining different types of steel (37°-38° helix) or stainless steel/heat resistant alloys (41°-42° helix) with the trochoidal milling techniques.
EXTRA LONG CUTTING LENGTH
Milling cutter dia. 6 - 25 mm Shank type DIN 6535 HA DIN 6535 HB Coating AlTiN / AlCr-based Number of flutes 5 Helix angle 37°-38° / 41°-42°
3xD Cutting length in a variable 37°-38° helix geometry for machining steel and a variable 41°-42° helix geometry for stainless steel and other heat resistant alloys.
CHIP BREAKER The chip breaker creates short chips and smooth chip evacuation to serve high cutting speeds when using the entire flute length.
Trochoidal milling Static
CORNER RADIUS AND CHAMFER
Dynamic
The 5 flute trochoidal tools are available with various corner radius and chamfer sizes.
