Value Collection 461-0155 M35 Cobalt Tool Bit Blank 7in

Product Description

The VALUE COLLECTION 461-0155 is a rectangle-profile tool bit blank ground from M35 cobalt high-speed steel. At 3/4 inch wide, 1 inch high, and 7 inches overall length, this blank gives machinists and tool grinders the raw stock needed to grind custom single-point turning, boring, or form tools to precise geometry. M35 cobalt content raises heat and wear resistance compared to standard M2 high-speed steel, making the finished tool suitable for harder workpiece materials and higher cutting temperatures. The ground finish on all faces provides consistent dimensions and a ready surface for sharpening to final geometry.

This tool bit blank is used in manual and CNC lathe setups, screw machine operations, and job shop environments where custom-ground tooling is required. Machinists select blanks like this when standard insert tooling does not suit the application or when a shop prefers to grind its own form tools in-house. The 7-inch length provides sufficient stock for regrinding multiple times over the tool's service life.

Key Features

• M35 cobalt high-speed steel construction for improved hot hardness and wear resistance
• Ground finish on all faces for dimensional consistency and ease of sharpening
• Rectangle cross-section profile: 3/4 inch wide by 1 inch high
• 7-inch overall length provides ample stock for regrinding
• Sold as a single blank, no minimum order beyond one piece

Compatibility

Designed as a general-purpose tool bit blank for use in standard lathe tool holders and grinder fixtures that accept 3/4 inch by 1 inch rectangular shank stock.

Installation Notes

Grinding tool bit blanks requires a bench or surface grinder equipped with an aluminum oxide or CBN wheel rated for high-speed steel. Secure the blank firmly in a tool grinder fixture before shaping to avoid freehand contact with the wheel. Always wear appropriate eye protection and allow the blank to cool between grinding passes to prevent drawing the temper of the cobalt steel. Final honing of cutting edges is typically done with a fine abrasive stone.
