02 / PRODUCT OVERVIEW

Check the configuration.

This square-end mill has a 0.25 in cutting diameter, 6 flutes and a Hybrid AlCrN coating. Length of cut is 0.625 in; overall length is 2.375 in. The square profile identifies the end geometry; the source does not provide a numerical corner-radius or edge-preparation tolerance.

The 0.25 in smooth shank must match the milling holder. Center cutting: Yes; variable pitch: No; chip splitter: No.

Listed primary workpiece groups: P - Steel. 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: P - Steel. Select engagement and cutting conditions for the exact material and assembly rigidity; no performance guarantee is inferred.

Selection guidance

Compare the 0.25 in cutting diameter, 0.625 in cutting length and square end profile with the part drawing. Match the 0.25 in smooth shank, then check toolholding grip and clearance using the 2.375 in overall length. Specify material, feature depth, overhang and quantity for quotation.
