Cleveland C44631 M2 Hss Tool Bit Blank 3/8x5/8x5 in

Product Description

The CLEVELAND C44631 is a ground tool bit blank manufactured from M2 high-speed steel. It measures 3/8 inches wide, 5/8 inches high, and 5 inches in overall length, with a rectangular cross-section that is precision ground for dimensional consistency. M2 high-speed steel offers a strong balance of red hardness, wear resistance, and toughness, making it a reliable material choice for cutting tool fabrication. This blank is used as raw stock for machinists and tool-and-die professionals who grind custom cutting tools to a specific profile for lathe, shaper, or planer operations.

This tool bit blank is suited for job shops, production machine shops, and tool rooms that require custom-ground cutting tool geometry. It is appropriate for use in both manual and CNC lathe applications where a shop-ground tool profile is preferred over an indexable insert. The rectangular blank form allows the machinist to grind relief angles, rake angles, and nose radii to match the material and operation at hand.

Key Features

• M2 high-speed steel construction provides strong wear resistance and heat tolerance during cutting operations
• Precision ground finish ensures accurate starting dimensions for custom tool grinding
• Rectangular cross-section allows straightforward clamping in standard tool holders and lantern-style post holders
• 5-inch overall length provides adequate stock for grinding multiple tool profiles or resharpening over the tool's service life
• 3/8 inches x 5/8 inches cross-section suits common light-duty to medium-duty lathe toolpost configurations

Compatibility

Designed as a standard rectangular HSS tool bit blank for use in tool holders and toolposts that accept 3/8-inch wide by 5/8-inch high shank dimensions, typical in manual and CNC lathe, shaper, and planer setups.

Installation Notes

Grinding of tool bit blanks should be performed by a qualified machinist using a bench or pedestal grinder fitted with an appropriate grinding wheel for high-speed steel. Ensure the grinder tool rest is properly adjusted and secured before beginning. Use coolant or frequent quenching to prevent overheating the steel, which can soften the cutting edge. Secure the finished tool bit firmly in the toolpost before engaging any workpiece.
