Cleveland C61019 2-Flute Carbide Corner Radius End Mill

Cleveland C61019 Carbide End Mill

The Cleveland C61019 is a 2-flute carbide corner radius end mill designed for general-purpose milling operations. It suits machinists and fabricators who need a durable, uncoated tool for creating rounded internal corners in a variety of materials. The solid carbide construction provides rigidity and wear resistance for consistent performance. This single-end tool is sold new and ready for immediate use in the workshop.

Build fit: tool holding and clearance

The tool features a 0.1875 inch milling diameter and a 0.01 inch corner radius, requiring a compatible tool holder for the shank. Its straight flute geometry and 1.25 inch length of cut define the maximum depth per pass, while the 2 inch overall length determines the reach inside the machine envelope. The uncoated surface allows for sharp edge retention on non-ferrous alloys and plastics. Operators must verify spindle speed and feed rates for their specific workpiece material.

Upgrade path: replacing worn or coated tools

This end mill replaces dull high-speed steel cutters or coated carbide tools where coating adhesion has failed. The jump is worth it when a sharp, uncoated carbide edge restores finish quality on aluminium, brass, or composite parts without the cost of recoating. It is not for buyers who need extended tool life from advanced coatings on abrasive steels, or for operations requiring a ball nose or square end profile instead of a corner radius.
