Value Collection 461-0127 M35 Cobalt Tool Bit Blank 8 in

Product Description

The VALUE COLLECTION 461-0127 is a rectangle-profile tool bit blank ground from M35 cobalt high-speed steel. At 0.5 inches wide, 1 inch high, and 8 inches in overall length, it provides machinists and toolmakers with a solid, unformed blank ready to be shaped and sharpened into custom cutting tools. M35 cobalt construction offers elevated heat resistance compared to standard high-speed steel, making this blank well-suited for demanding turning, boring, and form-tool applications on harder workpiece materials. The ground finish ensures dimensional consistency across the blank for precise tool fabrication.

This tool bit blank is used in metalworking shops, maintenance facilities, and production environments where custom single-point or form cutting tools are required. It is appropriate for manual grinding on a bench or pedestal grinder to produce lathe tools, parting tools, threading tools, and similar custom profiles. The 8-inch length allows multiple tools to be ground from a single blank or provides extra material for resharpening over the tool's service life.

Key Features

• M35 cobalt high-speed steel construction for improved heat and wear resistance
• Ground finish provides accurate cross-sectional dimensions for consistent tool fabrication
• Rectangle profile suits a wide range of single-point and form-tool geometries
• 8-inch overall length allows multiple grinding profiles or extended resharpening life
• 0.5 inches wide by 1 inch high cross-section fits standard lathe tool holders and grinding fixtures

Compatibility

Designed as a general-purpose cobalt tool bit blank for use in standard lathe tool holders and grinding fixtures that accept 0.5 inch by 1 inch rectangular shank stock.

Installation Notes

Tool bit blanks are ground to final geometry by a qualified machinist or toolmaker using a bench grinder, pedestal grinder, or surface grinder with an appropriate wheel for high-speed steel. Ensure the grinder is equipped with proper guards and that eye protection is worn during all grinding operations. Allow the blank to cool regularly during grinding to prevent overheating and loss of temper in the cutting edge. Secure the blank firmly in a grinding fixture or tool rest to maintain correct relief and rake angles.
