Accupro ACC-RAD3 Concave Radius Cutting Tool Bit

Product Description

The ACCUPRO ACC-RAD3 is a concave RAD style radius cutting tool bit designed for precision lathe and turning operations. This right-hand cut tool bit features a 3/32 inch radius profile and a carbide tip for extended wear resistance and consistent surface finish. The tool measures 2.5 inches in overall length with a 3/8 inch square shank that seats securely in standard tool holders. At 3/32 inch tip thickness and a 3/8 inch long tip, the ACC-RAD3 provides the geometry needed for forming accurate concave contours on metal workpieces. It is suited for machinists, toolroom operators, and production turning applications requiring repeatable radius profiles.

The ACC-RAD3 is used in lathe turning setups where a concave radius form must be cut into a workpiece in a single pass or series of controlled passes. The right-hand orientation positions the cutting edge for standard feed direction on most engine lathes and CNC turning centers. The carbide tip handles ferrous and non-ferrous materials encountered in job shop and production environments. This tool bit is sold individually and is appropriate for light to medium duty forming operations on manual and automated turning equipment.

Key Features

• Concave RAD style profile grinds a 3/32 inch radius contour in a single tool pass
• Carbide tip provides extended cutting life compared to high-speed steel alternatives
• Right-hand cut orientation for standard lathe feed direction
• 3/8 inch square shank fits common tool post and holder configurations
• 2.5 inch overall length with 3/8 inch long tip for reach and rigidity balance
• 3/32 inch tip thickness supports controlled chip formation on concave forms

Compatibility

Designed as an OEM-style radius form tool bit for use in standard tool post holders accepting a 3/8 inch square shank on manual engine lathes and CNC turning centers.

Installation Notes

Installation is performed by a machinist or toolroom technician. Secure the 3/8 inch square shank firmly in the tool post or holder before engaging the workpiece, ensuring the tool tip is set at centerline height. Power down and lock out the lathe spindle before changing or adjusting the tool bit. Inspect the carbide tip for chipping or wear before each use to avoid dimensional inaccuracy in the radius form.
