Accupro ACC-RAL14 Concave Radius Cutting Tool Bit

Product Description

The ACCUPRO ACC-RAL14 is a left-hand, concave radius cutting tool bit designed for precision profile turning and radius forming operations on a lathe. It follows the RAL style geometry and features a carbide-tipped cutting end for durability in demanding cutting conditions. The tool bit measures 4.5 inches in overall length with a 0.75-inch long tip, a tip thickness of 0.1875 inches, and a 0.75-inch square shank for solid tool post clamping. The 0.4375-inch concave radius makes it well suited for forming consistent curved profiles in a single pass. Machinists and tool and die tradespeople rely on this style of form tool for repetitive radius work where accuracy and repeatability matter.

This tool bit is used in manual and CNC lathe applications where a left-hand cutting direction is required. It is appropriate for use in job shops, maintenance machining, and production turning environments. The concave geometry allows the cutting edge to generate a convex radius on the workpiece. Common materials machined with carbide-tipped form tools of this type include steel, cast iron, and non-ferrous alloys. The RAL style configuration is a recognized industry form tool standard for radius lathe operations.

Key Features

• Concave cut type produces a convex radius profile on the workpiece
• 7/16-inch (0.4375-inch) radius for consistent profile forming
• Left-hand cutting orientation for specific tooling setups
• Carbide tip provides wear resistance on ferrous and non-ferrous materials
• 3/4-inch square shank fits standard tool post holders
• RAL style geometry follows a recognized industry form tool standard

Compatibility

Designed as a standard RAL-style radius cutting tool bit for use in lathes equipped with a 3/4-inch square tool post or holder. No specific machine model compatibility data was provided in the available product information.

Installation Notes

This tool bit is installed and set by a qualified machinist. Before mounting, ensure the lathe is powered down and the spindle is locked. Secure the 3/4-inch square shank firmly in the tool post to the correct center height before beginning any cutting operation. Follow applicable shop safety procedures and consult machine tooling documentation for feed rate and depth-of-cut guidance appropriate to the workpiece material.
