Value Collection 461-0070 M35 Cobalt Tool Bit Blank 6 in

Product Description

The VALUE COLLECTION 461-0070 is a rectangle-profile tool bit blank ground from M35 cobalt high-speed steel. It is designed as raw stock for machinists and tool grinders who need to profile, regrind, or fabricate custom single-point cutting tools. At 5/16 inches wide, 1 inch high, and 6 inches overall length, this blank provides sufficient material to grind a finished lathe tool, boring tool, or specialty cutter to exact geometry. The M35 cobalt grade offers improved red-hardness and wear resistance compared to standard M2 high-speed steel, making it suitable for harder workpiece materials and interrupted cuts.

This tool bit blank is used in machine shops, tool-and-die operations, and maintenance environments where off-the-shelf insert tooling is not practical. Typical applications include grinding custom form tools for manual lathes, shaper tools, planer tools, and specialty cutting profiles. It is appropriate for both production and repair applications where a machinist or tool grinder will finish-grind the cutting geometry on a bench or surface grinder before use.

Key Features

• M35 cobalt high-speed steel for improved heat and wear resistance over standard M2 HSS
• Rectangle cross-section profile — 5/16 inches wide by 1 inch high
• 6 inches overall length provides ample stock for grinding one or more tools
• Ground finish on all faces for consistent dimensional accuracy and easier bench grinding
• Suitable for turning, boring, shaping, and form-tool applications on manual machine tools

Compatibility

Designed as a general-purpose ground tool bit blank compatible with standard tool holders and lantern-style post setups that accept 5/16-inch wide rectangular HSS blanks on manual lathes and shapers.

Installation Notes

Tool bit blanks require finish grinding by a qualified machinist or tool grinder before use as a cutting tool. Use a suitable aluminum oxide or CBN wheel rated for high-speed steel when grinding the cutting geometry. Secure the blank firmly in a tool holder or grinding fixture before any machining operation. Always wear appropriate eye protection during grinding and follow applicable shop safety procedures.
