Cleveland C44509 Tool Bit Blank 3/16 in Square M2 Hss

Product Description

The CLEVELAND C44509 is a square-ground tool bit blank made from M2 high-speed steel, designed for use in custom tooling applications where machinists need to grind their own cutting edge geometry. Measuring 3/16 inches wide by 3/16 inches high with an overall length of 2.5 inches (63.50 mm), this blank ships in a pre-ground condition with a 10-degree bevel angle, providing a consistent starting surface. It is installed by machinists and toolroom professionals who require a reliable HSS substrate for form tools, lathe bits, and similar shop-ground tooling.

This tool bit blank is suited for general-purpose machining environments, including manual lathe work, turret lathe setups, and custom tool grinding operations. The square cross-section and ground finish make it straightforward to dress on a bench or pedestal grinder. It fits standard tool holders and lantern-style post holders that accept 3/16-inch square shank stock. Typical users include job shops, maintenance departments, and toolrooms handling ferrous and non-ferrous materials.

Compatibility

Designed as a standard 3/16-inch square tool bit blank for use in tool holders and grinding fixtures that accept M2 high-speed steel stock of this cross-section.

Installation Notes

Tool bit blanks are ground to final geometry by a qualified machinist using a bench grinder, surface grinder, or tool and cutter grinder. Secure the blank firmly in the tool holder before machining, and verify shank clearance in the holder before beginning any cut. Always wear eye protection and follow standard shop safety practices when dressing or grinding HSS tooling.
