Accupro ACC-RAL7 Concave Radius Cutting Tool Bit

Product Description

The ACCUPRO ACC-RAL7 is a left-hand, concave, RAL-style radius cutting tool bit designed for lathe and turning operations requiring precise concave radii. It measures 2.5 inches in overall length with a 7/32-inch radius and features a carbide tip for extended wear resistance on hard materials. The shank is 3/8-inch square, and the tip is 3/8 inches long and 3/32 inches thick. Machinists and toolroom technicians use this bit when producing concave profiles, grooves, or form features on metal workpieces. The carbide tip construction handles interrupted cuts and abrasive materials better than high-speed steel alternatives.

This tool bit is suited for manual and CNC lathe work in metalworking environments, including job shops, maintenance shops, and production facilities. The RAL-style geometry is a recognized form-tool configuration for concave radius turning. The left-hand orientation means cutting action is from left to right, which is standard for specific facing and profiling applications on a lathe. It is installed in a tool holder accepting a 3/8-inch square shank.

Key Features

• Carbide tip for improved wear resistance and longer tool life on hard or abrasive materials
• 7/32-inch concave radius for precise radius-turning operations
• 3/8-inch square shank for secure seating in compatible tool holders
• Left-hand cut orientation for right-to-chuck profiling passes
• RAL-style form geometry for consistent concave profile reproduction
• Compact tip dimensions: 3/8 inches long and 3/32 inches thick

Compatibility

Designed as an OEM-style replacement or direct-use tool bit for manual and CNC lathes equipped with tool holders accepting a 3/8-inch square shank.

Installation Notes

This tool bit is installed and serviced by machinists and toolroom technicians. Before changing tool bits, ensure the lathe is fully powered down and the spindle has come to a complete stop. Secure the shank firmly in the tool holder to the specified clamping torque for your holder per the holder manufacturer instructions. Verify correct tool height alignment to centerline before beginning a cut, as improper height will affect radius accuracy and tip life.
