Value Collection 461-0110 Tool Bit Blank M35 Cobalt

Product Description

The VALUE COLLECTION 461-0110 is a rectangular tool bit blank ground from M35 cobalt high-speed steel, intended for machinists and tool grinders who need to cut and profile their own single-point or form tools. The blank measures 3/8 inches wide, 1 inch high, and 6 inches in overall length, giving the operator ample stock to grind a custom cutting geometry for lathe, boring, or specialty applications. M35 cobalt HSS offers elevated hot hardness compared to standard M2, making it well suited for harder ferrous materials and interrupted cuts where heat buildup is a concern.

This tool bit blank fits standard tool post holders and grinder fixtures that accept rectangular shank stock. It is a common starting point in job shops, tool rooms, and maintenance departments where custom cutting tools are ground to specific profiles. The 6-inch length allows multiple regrinds over the life of the blank. It is used by machinists working on manual lathes, turret lathes, and manual milling setups that require a ground-to-spec single-point tool.

Key Features

• M35 cobalt HSS construction for improved hot hardness and wear resistance over standard M2
• Rectangular cross-section at 3/8 inches wide by 1 inch high fits common tool post holders
• 6-inch overall length provides substantial stock for initial grinding and multiple regrinds
• Unground blank allows full custom geometry to be applied by the end user
• Consistent cross-section geometry simplifies clamping and repeatability in the grinder fixture

Compatibility

Designed as a standard rectangular tool bit blank for use in manual lathe tool posts, turret lathe holders, and bench grinder fixtures that accept 3/8 x 1 inch rectangular shank stock.

Installation Notes

Tool bit blanks are ground to a custom cutting profile by a qualified machinist using a bench or surface grinder equipped with an appropriate grinding wheel rated for high-speed steel. Ensure the grinding wheel is properly dressed and that coolant or frequent quenching is used to prevent drawing the temper from the cobalt steel during grinding. Wear appropriate eye protection and follow shop safety practices during all grinding operations. The finished tool should be inspected for correct rake, relief, and nose radius before mounting in the tool post.
