Cleveland C39623 3-Flute HSS Center Cutting Square Double End Mill

Cleveland C39623 Double End Mill

The Cleveland C39623 is a 3-flute high-speed steel center cutting square double end mill designed for general milling operations. It suits machinists and maintenance technicians who need a versatile tool for slotting and profiling in various materials. The Weldon flat shank ensures secure clamping in standard tool holders. This tool is not for buyers who require carbide wear resistance or specialised geometries for high-speed machining.

High-Speed Steel Construction with TiCN Coating

The cutter body is manufactured from high-speed steel and features a TiCN coating to improve surface hardness and reduce friction during cutting. A 3/8 inch shank diameter with a Weldon flat provides a rigid, anti-slip connection in compatible end mill holders. The 0.3125 inch milling diameter and 0.75 inch length of cut define the cutting envelope. The overall length measures 3 1/2 inches for standard machine clearance. Builders needing extended reach or different shank configurations must select alternative tooling.

Ready-to-Use Cutting Tool

The product arrives as a single double end mill ready for immediate installation in a Weldon-compatible holder. No additional accessories, collets, or software are included in the package. Operators must supply appropriate tool holders, coolant, and work-holding solutions for their specific application. The absence of bundled items keeps the focus on the cutter's core geometry and coating performance. Shops requiring kits or multi-tool sets should look elsewhere.
