Value Collection 461-0115 M35 Cobalt Tool Bit Blank

Product Description

The VALUE COLLECTION 461-0115 is a rectangle ground tool bit blank made from M35 cobalt high-speed steel. It measures 1/2 inch wide, 3/4 inch high, and 4 inches in overall length. Cobalt tool bit blanks are used as raw stock for machinists and toolmakers who grind custom cutting tool profiles to suit specific lathe, shaper, or planer operations. The ground finish on all faces ensures dimensional accuracy and a consistent starting surface for tool grinding. M35 cobalt steel offers improved heat resistance and wear performance compared to standard M2 high-speed steel, making it suitable for harder workpiece materials and higher cutting speeds.

This tool bit blank is intended for use in machine shop environments where operators grind their own single-point cutting tools. Typical applications include turning, boring, threading, and facing operations on metal lathes. The rectangle profile fits standard tool holders and tool posts sized for 1/2 inch by 3/4 inch blanks. This blank is well suited for prototype work, toolroom use, and production settings where custom ground tooling is required. Machinists and tool grinders are the primary installers and end users of this product.

Key Features

• M35 cobalt high-speed steel for improved heat and wear resistance over standard HSS grades
• Rectangle ground profile provides a flat, accurate starting surface for custom tool grinding
• 1/2 inch wide by 3/4 inch high cross-section fits common lathe tool holders and posts
• 4 inch overall length provides sufficient stock for grinding and regrinding multiple times
• Sold individually, allowing single-piece procurement for toolroom and prototype applications

Compatibility

Designed as an OEM-style replacement blank for use in standard tool holders and tool posts accepting 1/2 inch by 3/4 inch rectangular high-speed steel blanks.

Installation Notes

Tool bit blanks require grinding to a finished cutting tool profile before use in a lathe or shaper. A bench or pedestal tool grinder with appropriate wheels for high-speed steel is needed. Wear eye protection and follow shop safety procedures when grinding cobalt HSS stock. Ensure the tool holder or post is securely clamped before machining operations begin.
