Accupro ACC-RC375040 Cut-off Grooving Tool Bit 3/8 Inch

Product Description

The ACCUPRO ACC-RC375040 is a single-point cut-off and grooving tool bit built for right-hand cutting operations on manual and CNC lathes. The tool features a solid carbide tip brazed to a steel shank, delivering the hardness and heat resistance required for interrupted cuts and narrow grooving passes. The shank measures 3/8 inch in both width and height, and the overall length is 6 inches. With a tip thickness and tip width each measuring 0.040 inches, this tool is suited for precise, narrow-groove work where dimensional control is critical. Machinists and toolroom technicians reach for this style when cutting off stock or machining grooves on ferrous and non-ferrous workpieces.

The ACC-RC375040 is designed for use on engine lathes, turret lathes, and CNC turning centers where a 3/8-inch tool holder or matching block is in use. The RC style and right-hand cutting direction make it a standard fitment for conventional cross-slide cut-off operations on bar stock and turned components. It is appropriate for production machining shops, tool rooms, and maintenance operations that require consistent, repeatable grooving or parting performance.

Key Features

• Solid carbide tip provides high wear resistance for cut-off and grooving applications

• Tip width and thickness of 0.040 inches enables precise, narrow groove profiles
• Right-hand cutting direction for standard cross-slide lathe operations
• 6-inch overall length provides adequate reach and rigidity in common tool post setups
• RC style conforms to industry standard number RC-375040

Compatibility

Designed as an OEM-style replacement and standard fitment for 3/8-inch tool holders and lathe tool blocks requiring an RC-style single-point cut-off and grooving bit. Industry standard number RC-375040.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank fully in the tool holder with appropriate set screws before operation, ensuring the tip is on center height relative to the workpiece. Inspect the brazed carbide tip for cracks or chip-out before each use. Follow the machine tool manufacturer guidelines for feed rate and spindle speed appropriate to the workpiece material and tip geometry.
