Accupro ACC-GF033-10 Full Radius Grooving Tool Solid Carbide

Product Description

The ACCUPRO ACC-GF033-10 is a full radius grooving tool designed for internal grooving operations on machined bores and holes. Built from solid micrograin carbide, it delivers the wear resistance and edge retention needed for precision grooving in ferrous and non-ferrous materials. The tool features a 5/16 inch shank diameter, a 0.0335 inch groove width, and a minimum hole diameter of 0.312 inches. With an overall length of 2.5 inches and a projection of 0.110 inches, it fits compact setups without sacrificing reach. Machinists and tool-and-die professionals rely on this geometry for clean, consistent full-radius profiles in production or job-shop environments.

This grooving tool is suited for CNC lathes and manual turning centers where internal grooving or undercutting is required. It handles bores with a minimum diameter of 0.312 inches and a maximum hole depth of 0.625 inches, making it appropriate for smaller-bore applications in precision machined components. The full radius profile is used when a completely rounded groove floor is specified by print, such as in retaining ring grooves, O-ring seats, or stress-relief undercuts in tight-tolerance parts.

Key Features

• Full radius geometry produces a completely rounded groove floor for O-ring seats and stress-relief cuts
• Solid micrograin carbide construction provides superior hardness and edge retention
• 5/16 inch shank diameter fits standard toolholders for small-bore internal work
• 0.0335 inch groove width for precise, narrow-profile grooving
• 0.110 inch projection accommodates grooving at depth without interference
• Maximum hole depth of 0.625 inches suits a range of short-bore applications

Compatibility

Designed for use in standard 5/16 inch bore grooving toolholders compatible with CNC or manual turning centers requiring a full radius internal grooving profile.

Installation Notes

This tool is installed and serviced by machinists familiar with turning center tooling setup. Ensure the machine spindle is fully stopped and the turret is in a safe index position before mounting or removing any tooling. Verify shank seating and tool projection against part geometry before initiating a cut. Follow the toolholder manufacturer guidelines for set screw torque and runout tolerances.
