ATORN SC end mill D 8.0 x 26 x 40 x 75mm, HB shaft 4 cutting edges, ULTRA MS
Brand: ATORN
Surface: ULTRA MS
Length: 75 mm
Art.-no. 16670323
Manufacturer article no. 11861392
EAN 4050293363166
Application
HPC end mill with uneven helical and uneven pitch for rough machining and finish machining of stainless steel, titanium alloy, nickel and copper alloys. The uneven helical pitch means that vibrations on the tool are reduced, which results in outstanding finished surfaces, while, at the same time, feed rates and cutting depths can be increased.
Execution
- ultra-fine grain cemented carbide
- with uneven helical and cutter distribution (35/38°)
- HB straight shank
- with clearance
- high-performance ULTRA MS layer
- with edge protection chamfer
- defined cutting edge rounding
- centre cutting
Advantage
- rough machining and finishing with just one tool
- optimum suitability for trochoidal milling
- HPC geometry for maximum feed rates and running smoothness
- suitable for large cutting depths
