Accupro ACC-RXD12 Convex Radius Cutting Tool Bit

Product Description

The ACCUPRO ACC-RXD12 is a convex radius cutting tool bit designed for precision radius-form turning on manual and CNC lathes. At 3.5 inches in overall length with a 3/8-inch convex radius, this right-hand tool bit generates smooth, accurate radius profiles in a single pass. The carbide tip provides hardness and wear resistance suited for interrupted cuts and continuous turning on ferrous and non-ferrous materials. The 0.5-inch square shank seats securely in standard tool holders, and the 0.125-inch tip thickness gives the insert a compact profile suited for close-clearance operations. Machinists and tool-and-die professionals use this style of radius bit where a consistent concave groove or convex form is required on the workpiece.

The ACC-RXD12 fits typical production and job-shop turning applications where a right-hand RXD-style radius cutter is specified. It is well suited for generating convex forms on shafts, bearing seats, and decorative profiles in materials ranging from mild steel to aluminum. The carbide-tipped construction handles moderate to high cutting speeds without the tip degradation common with high-speed steel alternatives. Operators running standard 0.5-inch square tool holders will find this bit drops directly into existing setups without modification.

Key Features

• Convex cutting geometry produces accurate 3/8-inch radius profiles in a single pass
• Carbide tip for extended wear life on ferrous and non-ferrous materials
• Right-hand cut orientation for standard lathe setups
• 0.5-inch square shank fits common tool holders without modification
• 3.5-inch overall length with 0.125-inch tip thickness for close-clearance work
• RXD-style form compatible with radius turning applications requiring a fixed-profile insert

Compatibility

Designed as a direct-fit replacement or new installation in standard 0.5-inch square shank tool holders used in manual and CNC lathe applications requiring a right-hand RXD-style convex radius cutter.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and locked out before seating or adjusting the tool bit in the holder. Secure the shank firmly in the tool post to the appropriate clamping torque specified by the tool holder manufacturer. Verify tool height and radius alignment against a reference gauge before taking a finish pass.
