Value Collection 461-0015 M35 Cobalt Tool Bit Blank 3 Inch

Product Description

The VALUE COLLECTION 461-0015 is a rectangle-ground tool bit blank made from M35 cobalt high-speed steel, intended for machinists and toolroom operators who grind their own custom cutting tools. At 1/4 inch wide, 1/2 inch high, and 3 inches in overall length, this blank provides a solid starting stock for single-point lathe tools, threading tools, and specialty form tools. The M35 cobalt alloy composition delivers increased red hardness and wear resistance compared to standard M2 high-speed steel, making it well suited for cutting harder workpiece materials and interrupted-cut applications. Each blank is supplied ground, ensuring consistent dimensional accuracy right out of the box.

This tool bit blank is used in manual and CNC turning centers, lathes, and boring applications where a custom-ground tool profile is required. It is a standard choice in general metalworking, toolroom, and maintenance machining environments. The 1/4 inch by 1/2 inch cross-section fits tool holders and lantern-style tool posts sized for this shank dimension. Package quantity is 1 piece.

Key Features

• M35 cobalt high-speed steel for superior red hardness and extended tool life in tough materials
• Ground finish provides consistent dimensional accuracy across width, height, and length
• Rectangle cross-section (1/4 inch wide x 1/2 inch high) accepts standard tool holders for this shank size
• 3-inch overall length gives adequate stock for grinding multiple tool profiles over the blank's service life
• Suitable for single-point turning, threading, boring, and form-tool applications

Compatibility

Designed as an OEM-style replacement or stock blank for use in tool holders and lantern-style tool posts that accept a 1/4 inch by 1/2 inch rectangular shank tool bit.

Installation Notes

Tool bit blanks are ground to final geometry by a qualified machinist or toolroom professional using a bench or pedestal grinder fitted with appropriate grinding wheels for high-speed steel. Always wear face and eye protection when grinding, and dress the grinding wheel before use. Ensure the tool post or holder is secured and the lathe or machine is powered down before seating or removing the finished tool bit. Follow applicable shop safety standards when handling freshly ground tooling, as edges are sharp.
