Accupro ACC-GR086002 Cut-off Grooving Tool Bit 3/8 Shank

Product Description

The ACCUPRO ACC-GR086002 is a single point cut-off and grooving tool bit designed for precision external grooving operations on CNC lathes and manual turning centers. Built with a micrograin solid carbide tip brazed to a rigid steel shank, this GR-style bit delivers consistent groove geometry in ferrous and non-ferrous materials. The right-hand cutting direction suits standard spindle configurations. Key dimensional specs include a 0.086 inch minimum groove width, a 0.27 inch maximum depth of cut, and a minimum nose radius of 0.002 inch, making it suited for tight-tolerance groove profiles in production turning.

This tool bit is used in job shops, production machining cells, and toolroom environments where accurate groove width control is required. The GR style is a common format for cut-off and grooving applications on conventional and CNC turning equipment. The 3/8 inch shank width and 3/4 inch shank height fit standard tool holders sized for this shank cross-section, making it a practical drop-in for many existing setups. Machinists and CNC operators working in automotive, aerospace, and general metalworking applications will find the micrograin carbide grade appropriate for demanding interrupted and continuous cuts.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician with the machine in a full stop, locked-out, and tagged-out state before any tool change. Ensure the tool holder clamping screws are torqued according to the tool holder manufacturer specifications and that the cutting edge is set at or near center height for the workpiece diameter. Inspect the brazed carbide tip for any micro-cracks or seating issues before the first cut. Follow applicable shop safety procedures and machine tool operation standards during setup and use.
