Accupro ACC-RAD10 Concave Radius Cutting Tool Bit

Product Description

The ACCUPRO ACC-RAD10 is a right-hand, concave RAD-style radius cutting tool bit designed for forming smooth, accurate concave radii on metal workpieces in turning and lathe operations. The carbide-tipped insert provides durable cutting performance on a range of ferrous and non-ferrous materials. The bit measures 3.5 inches in overall length with a 0.5-inch tip length, 0.125-inch tip thickness, and a 5/16-inch concave cutting radius. The 0.5-inch square shank allows secure mounting in standard tool holders. Machinists and tool-and-die professionals install this bit for radius turning, form turning, and profile finishing operations where consistent concave geometry is required.

This tool bit is suited for use on manual engine lathes, turret lathes, and CNC turning centers equipped with square-shank tool holders. It is appropriate for production shops, maintenance machining, and job-shop environments where repeatable radius profiles are machined into shafts, pins, grooves, or mating components. The right-hand orientation positions the cutting edge for standard front-toolpost operation. The carbide tip handles interrupted cuts and harder materials better than high-speed steel alternatives, making it a practical choice when tool life and surface finish consistency matter.

Key Features

• 5/16-inch concave cutting radius for accurate radius-form turning
• Carbide tip for extended tool life and performance on hard materials
• Right-hand cut orientation for standard front-toolpost lathe setups
• 0.5-inch square shank fits standard square-shank tool holders
• 3.5-inch overall length with 0.5-inch tip length and 0.125-inch tip thickness
• RAD-style geometry for consistent concave profile forming

Compatibility

Designed as an OEM-style replacement and standard-fit tool bit for lathes and turning centers that accept 0.5-inch square-shank tool holders requiring a right-hand concave radius cutting configuration.

Installation Notes

Installation is performed by qualified machinists following standard shop safety procedures. Secure the shank fully in the tool holder and ensure the cutting tip is set to centerline height before operation. Confirm all toolpost and turret fasteners are torqued according to machine manufacturer specifications before engaging the cut. Power down and de-energize the machine before changing or adjusting any cutting tool.
