Value Collection 460-2330 M35 Cobalt Tool Bit Blank 3/8 X 8 in

Product Description

The VALUE COLLECTION 460-2330 is a square tool bit blank machined from M35 cobalt high-speed steel. Measuring 3/8 inches wide by 3/8 inches high with an 8-inch overall length, this blank is intended for machinists and toolmakers who grind their own single-point cutting tools to a custom profile. M35 cobalt steel offers greater heat and wear resistance than standard M2 HSS, making it well suited for cutting harder workpiece materials. This blank ships unground, ready for the bench grinder or surface grinder.

Square tool bit blanks of this type are used in manual and CNC lathe toolholders, boring bars, and fly cutters in both jobshop and production machine shop environments. The 3/8-inch cross-section fits toolholders rated for 3/8-inch tool bits, which are common on mid-size engine lathes and turret lathes. Machinists, tool and die makers, and apprentice toolmakers typically purchase these blanks in small quantities for custom profile grinding or regrinding worn tool bits.

Key Features

• M35 cobalt HSS construction for improved hot hardness and wear resistance over standard M2
• Square cross-section at 3/8 inches wide by 3/8 inches high for consistent seating in standard toolholders
• 8-inch overall length provides ample stock for multiple grinds over the life of the blank
• Unground blank allows full custom profile shaping at the bench or surface grinder
• Lightweight at approximately 0.027 pounds per piece

Compatibility

Designed for use in any toolholder or boring bar accepting a 3/8-inch square tool bit shank, typical of mid-size manual and CNC lathes.

Installation Notes

Grinding of tool bit blanks should be performed by a qualified machinist or toolmaker using appropriate grinding wheels rated for cobalt HSS. Eye protection and a work rest set to the correct clearance angle are required at the grinder. Secure the blank firmly in the toolholder set screw before taking any cut, and verify the tool overhang is minimized to reduce chatter.
