Value Collection 360-0148 Tool Bit Blank M2 Hss 3/4in Square

Product Description

The VALUE COLLECTION 360-0148 is a square tool bit blank ground from M2 high speed steel for use in manual and CNC lathe tooling setups. At 3/4 inches wide by 3/4 inches high with a 5-inch overall length, it provides the raw stock a machinist or toolroom technician needs to grind a custom cutting edge to a specific profile. M2 is the most widely used high speed steel grade, offering a balanced combination of hardness, toughness, and wear resistance suitable for general-purpose cutting applications on ferrous and non-ferrous materials.

This blank is intended for use in machine shops, toolrooms, and production environments where off-the-shelf insert geometry does not meet the required profile. It is typically used to produce single-point turning tools, boring bars, parting tools, or other custom lathe tooling. The square cross-section and ground finish allow the machinist to hold consistent dimensions before final grinding to the desired rake, relief, and nose geometry.

Key Features

• M2 high speed steel construction for strong hardness and wear resistance across general cutting applications
• Square cross-section at 3/4 inches wide by 3/4 inches high provides consistent stock for custom tool grinding
• Ground finish ensures dimensional accuracy before profiling
• 5-inch overall length gives adequate shank depth for most standard tool holders
• Single-piece quantity suitable for low-volume toolroom use or replacement stock

Compatibility

Designed as an OEM-style replacement or toolroom stock blank for use in standard lathe tool holders and boring bar setups that accept 3/4-inch square shank tool bits.

Installation Notes

Tool bit blanks are ground to final geometry by a machinist or tool grinder using a bench or pedestal grinder with appropriate grinding wheels rated for high speed steel. Personal protective equipment including a face shield is required during grinding operations. Ensure the tool holder is securely clamped and the machine is powered down before seating or removing any tool bit. Follow shop safety procedures and applicable OSHA standards for grinding and lathe operations.
