Value Collection 461-0105 M35 Cobalt Tool Bit Blank

Product Description

The VALUE COLLECTION 461-0105 is a rectangle ground tool bit blank made from M35 cobalt high-speed steel. Designed for machinists and toolroom professionals, this blank measures 3/8 inches wide, 3/4 inches high, and 6 inches in overall length. It is supplied in a ground finish, providing a consistent, flat surface that allows the user to grind a custom cutting edge to the geometry required for a specific turning, boring, or facing operation. M35 cobalt steel offers increased heat resistance compared to standard M2 high-speed steel, making it well suited for harder workpiece materials and higher cutting speeds.

This tool bit blank is used in manual and CNC lathe operations where a custom-ground single-point cutting tool is needed. It is appropriate for general-purpose turning applications in job shops, toolrooms, and production environments. The blank format gives the machinist full control over relief angles, rake angles, and nose radius geometry. It is typically used with a bench or tool grinder to shape the cutting end before mounting in a tool holder or tool post on a lathe or boring machine.

Key Features

• M35 cobalt high-speed steel construction for improved heat and wear resistance over standard HSS
• Ground finish provides a flat, consistent starting surface for custom tool grinding
• Rectangle cross-section: 3/8 inches wide by 3/4 inches high
• 6-inch overall length provides material for grinding and resharpening over the tool's service life
• Suitable for machining harder ferrous materials where standard M2 HSS loses cutting edge integrity

Compatibility

Designed as a general-purpose lathe tool bit blank compatible with standard tool holders and tool posts that accept 3/8 inch by 3/4 inch shank tool bits in manual and CNC turning applications.

Installation Notes

Tool bit blanks must be ground to a specific cutting geometry before use; this work is performed by a qualified machinist using a bench grinder or tool and cutter grinder with appropriate grinding wheels for cobalt HSS. Ensure the lathe or machine tool is powered down and locked out before mounting or changing any tool bit. Secure the ground tool bit firmly in the tool holder to the torque specified by the tool holder manufacturer before commencing any cutting operation. Follow applicable shop safety standards when grinding cobalt HSS materials, including the use of eye protection and proper ventilation.
