Value Collection 361-0080 M2 Hss Tool Bit Blank 3/8x1/2x4in

Product Description

The VALUE COLLECTION 361-0080 is a rectangle-ground tool bit blank machined from M2 high speed steel. It measures 3/8 inches wide, 1/2 inches high, and 4 inches in overall length. Tool bit blanks are unformed cutting tool stock used by machinists and tool grinders to create custom single-point lathe tools, form tools, and specialty cutters. The ground finish on this blank provides a consistent, close-tolerance starting surface, reducing the amount of material removal required during the grinding process. At 0.31 pounds, the blank is compact and suited for bench grinding or surface grinding setups in a machine shop environment.

This blank is intended for use in manual and CNC lathe tooling applications where a custom-ground cutting profile is required. Machinists and tool and die makers select M2 HSS blanks when they need a cost-effective, re-grindable cutting tool material that holds a keen edge across a range of ferrous and non-ferrous workpiece materials. Typical applications include turning, facing, boring, and threading operations performed on manual engine lathes and turret lathes in job shop, maintenance, and production environments.

Key Features

• M2 high speed steel construction provides good wear resistance and toughness for general-purpose cutting tool grinding
• Rectangle ground profile offers a flat, consistent starting surface for precise custom tool grinding
• 3/8 inches wide by 1/2 inches high cross-section fits standard tool holders and post holders sized for this geometry
• 4 inches overall length provides sufficient stock for initial grinding and multiple re-grinds over the tool life
• Compact 0.31-pound weight makes handling and bench-grinding setup straightforward

Compatibility

Designed as a general-purpose HSS tool bit blank compatible with standard tool post holders and grinding fixtures that accept a 3/8 inches wide by 1/2 inches high rectangular cross-section blank.

Installation Notes

Tool bit blanks require grinding to a final cutting geometry before use in a lathe or other machine tool. Grinding should be performed by a qualified machinist using appropriate bench or surface grinding equipment with a suitable wheel for high speed steel. Eye protection and proper wheel guards must be in place during all grinding operations. Secure the finished tool bit firmly in the tool post holder and verify clearance angles before engaging the workpiece.
