Accupro ACC-RAL11 Concave Radius Cutting Tool Bit

Product Description

The ACCUPRO ACC-RAL11 is a left-hand, concave radius cutting tool bit designed for precision radius turning and profiling operations on a lathe. Built in the RAL style, this carbide-tipped bit measures 3.5 inches in overall length with an 11/32-inch concave radius. The shank is 0.5 inches square, and the tip is 0.5 inches long and 0.125 inches thick. The carbide tip provides hardness and wear resistance suited to interrupted cuts, harder workpiece materials, and production turning environments. Machinists and toolroom technicians install this bit into standard tool holders on manual or CNC lathes.

This tool bit is used for generating concave radius forms on turned parts, including grooves, cove profiles, and blended radius transitions. The left-hand orientation determines the direction of cut and tool approach, making it appropriate for specific facing and turning setups where a right-hand bit would interfere with the part or chuck. It fits standard 0.5-inch square shank tool holders commonly found in production and job-shop lathe setups across industrial, maintenance, and tool-and-die applications.

Key Features

• Concave RAL-style profile for accurate radius turning and form work
• 11/32-inch radius for consistent, repeatable concave profiles
• Carbide tip for durability and performance in harder materials
• Left-hand cut orientation for specific tool approach configurations
• 0.5-inch square shank fits standard lathe tool holders
• 3.5-inch overall length with 0.5-inch tip and 0.125-inch tip thickness

Compatibility

Designed as an OEM-style form tool bit for use in standard 0.5-inch square shank lathe tool holders on manual and CNC turning machines.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the lathe before inserting or adjusting the tool bit in the holder. Ensure the bit is seated squarely and clamped securely before resuming operation. Inspect the carbide tip for chips or cracks before each use, as a damaged tip can affect radius accuracy and workpiece finish.
