Value Collection 461-0000 M35 Cobalt Tool Bit Blank

Product Description

The VALUE COLLECTION 461-0000 is a rectangle-ground tool bit blank machined from M35 cobalt high-speed steel. Measuring 3/16 inches wide, 5/16 inches high, and 4 inches in overall length, this blank is supplied in a ground finish, ready for custom grinding to a specific cutting geometry. M35 cobalt grade provides increased heat and wear resistance compared to standard M2 high-speed steel, making it well-suited for interrupted cuts and harder work materials. Machinists and tool-and-die professionals use blanks like this to create custom single-point lathe tools, form tools, and specialty cutters ground to exact profiles for a given job.

This tool bit blank is used in manual and CNC metal-turning applications where a standard insert geometry does not meet the required profile. It is appropriate for use in engine lathes, turret lathes, and similar machine tool setups. The rectangular cross-section seats securely in standard tool holders and tool posts. Typical applications include turning, facing, and boring operations on ferrous and non-ferrous metals, stainless alloys, and other materials that benefit from cobalt-grade tooling.

Key Features

• M35 cobalt high-speed steel for improved heat resistance and tool life over standard HSS grades
• Ground finish on all faces for consistent dimensional accuracy out of the box
• Rectangle cross-section seats stably in standard tool holders and lantern-style tool posts
• 4-inch overall length provides sufficient shank for secure clamping with usable cutting end
• Blank form allows the end user to grind any custom cutting geometry as required by the application

Compatibility

Designed as an OEM-style replacement or stock blank for use in standard tool holders accepting 3/16-inch by 5/16-inch rectangular high-speed steel tool bits.

Installation Notes

Tool bit blanks are ground to final cutting geometry by a qualified machinist using a bench or surface grinder with an appropriate wheel rated for high-speed steel. Secure all workholding and follow standard machine-shop safety practices before grinding. The finished tool should be seated in the tool holder with adequate overhang minimized to reduce chatter. Always verify the cutting geometry and clearance angles are correct for the specific material and operation before engaging the workpiece.
