Value Collection 461-0065 M35 Cobalt Tool Bit Blank

Product Description

The VALUE COLLECTION 461-0065 is a rectangle-ground tool bit blank machined from M35 cobalt high-speed steel. Blank-style bits are unformed cutting tools that machinists grind to a custom profile for turning, boring, threading, or other lathe and shaper operations. At 5/16 inches wide, 3/4 inches high, and 5 inches overall length, this blank provides solid stock for grinding a range of tool geometries. The M35 cobalt grade offers improved hot hardness and wear resistance compared to standard M2 high-speed steel, making it well suited for harder workpiece materials and higher cutting speeds. The ground finish ensures dimensional accuracy and a consistent surface for precise tool grinding.

This tool bit blank is used in machine shops, maintenance departments, and toolrooms where custom-ground cutting tools are required. It fits standard tool holders sized for 5/16 inches by 3/4 inches shank stock. Typical applications include single-point turning tools on engine lathes, form tools, and shaper cutters. Machinists working with stainless steel, cast iron, titanium alloys, and other difficult-to-machine materials benefit from the elevated cobalt content in M35 grade, which maintains a sharper cutting edge at elevated temperatures.

Key Features

• M35 cobalt high-speed steel construction for improved wear resistance and hot hardness
• Rectangle ground profile for precise fitment in standard tool holders
• 5/16 inches wide by 3/4 inches high cross-section for common lathe and shaper setups
• 5 inches overall length provides ample stock for grinding and regrinding
• Ground finish ensures dimensional consistency across the blank

Compatibility

Designed as a standard replacement or stock blank for tool holders and lathe toolposts accepting 5/16 inches by 3/4 inches rectangular high-speed steel bit stock.

Installation Notes

Tool bit blanks are installed by qualified machinists or toolroom personnel after grinding to the desired cutting geometry. Secure the ground bit firmly in the tool holder or toolpost before engaging any workpiece. Inspect the ground edge for cracks or chips before use. Follow all machine guarding and personal protective equipment requirements applicable to grinding and turning operations.
