Carbide End Mill for Milling Operations

This carbide end mill is built for milling tasks in workshop and production environments. The uncoated carbide construction suits general-purpose cutting across a range of materials. It is intended for machinists and fabricators who need a reliable square-end tool for slotting, profiling and face milling.

Upgrading from High-Speed Steel Cutters

Switching from high-speed steel to carbide delivers harder cutting edges that resist wear at higher speeds. The change is worthwhile when cycle times matter and tool changes must be minimised. Shops running longer batches or tougher alloys will see the benefit in reduced downtime and more consistent part finish.

Limits of Uncoated Carbide in Straight-Shank Tools

Uncoated carbide performs best in rigid setups with good chip evacuation and appropriate coolant strategy. Without a coating, the edge is more sensitive to heat buildup in deep slots or high-feed passes. The straight shank requires a matching holder; the tool cannot be used with coolant-through spindles or in holders that demand a necked shank.

Questions about this item

What shank diameter does the C60640 end mill need in the tool holder?

The shank diameter is 5/8 in., so the holder or collet must accept that exact size.

How should the 0.625 in. carbide end mill be secured to avoid run-out?

Clamp the 5/8 in. shank fully in a precision collet or shrink-fit holder, tightening evenly; the common mistake is leaving a gap between the shank and the collet face.

When will the uncoated carbide flutes need replacement?

Replace the tool when the 2.5 in. cutting edges show visible wear, chipping, or when surface finish degrades, as the uncoated carbide cannot be re-sharpened economically.
