Value Collection 461-0120 M35 Cobalt Tool Bit Blank 6 Inch

Product Description

The VALUE COLLECTION 461-0120 is a rectangle-ground tool bit blank machined from M35 cobalt high-speed steel. It measures 1/2 inch wide, 3/4 inch high, and 6 inches in overall length, giving machinists a solid, unformed blank ready for custom grinding to a specific cutting geometry. M35 cobalt alloy offers improved heat and wear resistance compared to standard M2 high-speed steel, making it a reliable choice for harder workpiece materials and interrupted cuts. This blank weighs approximately 0.5 pounds and arrives ground to consistent dimensions for repeatable tool room use.

This tool bit blank is suited for machine shops, tool rooms, and production environments where custom lathe, shaper, or planer tooling is regularly ground in-house. It is appropriate for use in general-purpose turning, facing, boring, and threading applications where a custom-profiled HSS tool is preferred over indexable insert tooling. Machinists working with stainless steel, cast iron, or other tough alloys will benefit from the cobalt content when grinding aggressive rake and relief angles.

Key Features

• M35 cobalt high-speed steel construction for improved heat resistance and tool life over standard HSS
• Rectangle ground profile with consistent 1/2 inch width and 3/4 inch height for accurate tool room grinding
• 6 inch overall length provides ample stock for initial grinding and future regrinding
• Ground finish ensures dimensional accuracy and a flat seating surface in tool holders
• Blank form allows custom geometry to be ground for lathe, shaper, planer, or specialty tooling applications

Compatibility

Designed as a general-purpose tool bit blank for use in standard tool holders and grinding fixtures that accept 1/2 inch by 3/4 inch rectangular HSS blanks.

Installation Notes

Tool bit blanks require bench or surface grinding by a qualified machinist before use as a cutting tool. Dress the grinding wheel appropriately for cobalt HSS material and use cutting fluid or coolant to prevent overheating, which can draw the temper from the blank. Secure the blank firmly in a grinding fixture or tool rest to maintain accurate relief and rake angles. Always wear appropriate eye protection and follow shop safety procedures when grinding.
