Value Collection 461-0020 M35 Cobalt Tool Bit Blank

Product Description

The VALUE COLLECTION 461-0020 is a rectangular tool bit blank ground from M35 cobalt high-speed steel. It measures 0.25 inches wide, 0.5 inches high, and 4 inches in overall length. Tool bit blanks are unground stock used by machinists and tool-and-die professionals to fabricate custom cutting tools, form tools, or lathe bits ground to a specific profile. M35 cobalt steel offers elevated heat resistance compared to standard M2 high-speed steel, making it well-suited for harder workpiece materials and interrupted cuts where tool temperatures rise quickly.

This blank is suited for use in manual and CNC turning, boring, and form-tool applications where a shop-ground or reground profile is required. The rectangular cross-section is the most common format for single-point lathe tooling. Machinists grind the blank to the required rake, relief, and nose geometry on a bench grinder or tool-and-cutter grinder. It is a standard size compatible with tool holders and lantern-style post systems that accept 0.25-inch wide by 0.5-inch high blanks.

Key Features

• M35 cobalt high-speed steel construction for improved heat and wear resistance
• Rectangular cross-section: 0.25 inches wide by 0.5 inches high
• 4-inch overall length provides adequate stock for grinding and regrinding multiple times
• Unground blank allows custom profiling to any cutting geometry
• Consistent material hardness throughout the blank supports precise tool grinding

Compatibility

Designed as an OEM-style replacement or shop-stock blank for use in standard tool holders and lantern post systems accepting a 0.25-inch by 0.5-inch rectangular tool bit profile.

Installation Notes

Tool bit blanks are ground to final geometry by a qualified machinist using a bench grinder or tool-and-cutter grinder equipped with an appropriate wheel for high-speed steel. Eye protection and proper wheel guards must be in place during grinding operations. Secure the blank firmly in a tool rest or grinding fixture to maintain consistent angles. Verify the finished tool geometry and edge condition before mounting in the tool holder and taking a cut.
