M.A. Ford TuffCut DM 156M0400N40A

This M.A. Ford TuffCut DM end mill is a precision cutting tool designed for milling operations. It features a 2-flute ball nose geometry with a necked design and a 4.0 mm diameter. The tool is manufactured by M.A. Ford for professional machining applications.

Suited for machinists needing a ball nose profile

This cutter suits operators performing contouring, profiling or 3D surfacing where a ball nose is required. The necked shank provides reach for deeper cavities. Buyers needing a flat end, corner radius or a different flute count should look at alternative tool geometries.

Standard shank fits common collets and holders

Installation follows normal tool-holding practice: secure the shank in a collet, shrink-fit or hydraulic holder rated for the shank diameter. Common issues include excessive run-out from worn collets, insufficient clamping length or incorrect feed and speed parameters causing premature wear or breakage.
