Accupro ACC-RAL10 Concave Radius Cutting Tool Bit

Product Description

The ACCUPRO ACC-RAL10 is a left-hand, concave radius cutting tool bit designed for precision radius turning and forming operations on a lathe. Built to the RAL style specification, it features a carbide-tipped construction that provides hardness and wear resistance for demanding machining applications. The bit measures 3.5 inches in overall length with a 5/16-inch concave radius, a 0.5-inch square shank, a 1/2-inch long tip, and a 1/8-inch tip thickness. Machinists and toolroom operators use this bit when left-hand cutting orientation is required for radius profiles on metal workpieces.

This tool bit is suited for conventional lathe work in job shops, production machining environments, and maintenance machining applications. The RAL style geometry is a recognized form tool configuration used when producing consistent concave radii on turned parts. The left-hand cut direction suits specific workholding and feed direction setups where a right-hand bit would not be appropriate. It is sold individually and is compatible with tool holders accepting a 1/2-inch square shank.

Key Features

• Concave cutting geometry produces consistent 5/16-inch radius profiles
• Left-hand cut orientation for specific lathe setup requirements
• Carbide-tipped construction for wear resistance on metal stock
• 1/2-inch square shank fits standard tool holders and turrets
• RAL style form factor for recognized radius tooling applications
• Overall length of 3.5 inches with a 1/8-inch tip thickness

Compatibility

Designed as a direct-fit replacement or standard tool bit for lathes and turret setups accepting a 1/2-inch square shank tool holder in RAL style radius tooling applications.

Installation Notes

Installation is performed by a machinist or toolroom technician. The lathe must be powered down and the spindle brought to a full stop before inserting or removing tool bits from the holder. The shank should be seated fully and clamped securely in the tool post or turret to prevent movement under cutting loads. Follow applicable shop safety procedures and machine manufacturer guidelines when setting tool height and feed direction for left-hand cutting operations.
