02 / PRODUCT OVERVIEW

Check the configuration.

This square-end mill has a 8 mm cutting diameter, 3 flutes and an uncoated finish. Length of cut is 20 mm; overall length is 63 mm. The square profile identifies the end geometry; the source does not provide a numerical corner-radius or edge-preparation tolerance.

The 8 mm smooth shank must match the milling holder. Center cutting: Yes; variable pitch: No; chip splitter: No.

Listed primary workpiece groups: N - Aluminum. The enquiry covers one cutter; a holder, collet and accessories are not established as included. No cutting speed, feed, finish, tool-life or accuracy rating is established by these dimensions.

Applications

Pocket, shoulder and profile milling where a square-end tool geometry is required. Listed primary workpiece groups: N - Aluminum. Select engagement and cutting conditions for the exact material and assembly rigidity; no performance guarantee is inferred.

Selection guidance

Compare the 8 mm cutting diameter, 20 mm cutting length and square end profile with the part drawing. Match the 8 mm smooth shank, then check toolholding grip and clearance using the 63 mm overall length. Specify material, feature depth, overhang and quantity for quotation.
