Accupro ACC-RAL3 Concave Radius Cutting Tool Bit 3/32 in

Product Description

The ACCUPRO ACC-RAL3 is a left-hand, concave radius cutting tool bit designed for lathe and turning operations requiring precise radius profiles. Built in the RAL style, this carbide-tipped bit measures 2.5 inches in overall length with a 3/8-inch square shank for secure tool post mounting. The tip is 3/32 inch thick and 3/8 inch long, providing the rigidity needed for consistent, repeatable cuts. Machinists and tool-and-die professionals use this type of bit when forming concave radii on ferrous and non-ferrous workpieces. The carbide tip delivers extended wear resistance compared to high-speed steel alternatives, making it a reliable choice for production and maintenance machining environments.

This tool bit is suited for use on manual engine lathes, turret lathes, and similar turning equipment where RAL-style radius bits are called out by the machine tool setup. The left-hand orientation means the tool cuts when feeding from left to right relative to the workpiece, which is the standard requirement for specific profiling and finishing passes. It is commonly installed by machinists in job shops, maintenance facilities, and manufacturing operations that require controlled radius forms on shafts, fittings, and mechanical components.

Key Features

• Concave cut profile produces a 3/32-inch radius form on the workpiece
• Carbide tip provides extended tool life and heat resistance during cutting
• Left-hand orientation for right-to-left feed direction applications
• 3/8-inch square shank fits standard tool post holders without modification
• RAL style conforms to recognized radius tool geometry standards
• Compact 2.5-inch overall length suits tight machine clearances

Compatibility

Designed as an OEM-style replacement or direct-fit tool bit for lathe tool posts and holders accepting a 3/8-inch square shank, consistent with RAL-style radius tool specifications.

Installation Notes

Installation is performed by qualified machinists familiar with lathe tooling setup. Secure the shank firmly in the tool post holder and verify the tool tip height is set on center before engaging the workpiece. Always power down and lock out the lathe before changing or adjusting tool bits. Do not use a damaged or chipped carbide tip, as this can affect radius accuracy and create a safety hazard.
