Scientific Cutting Tools GT087-12A Retaining Ring Grooving Tool

Product Description

The SCIENTIFIC CUTTING TOOLS GT087-12A is a solid carbide retaining ring grooving tool designed for internal grooving operations in precision machining applications. Built from submicron-grade solid carbide, this left-hand cutting tool delivers accurate groove placement in bores starting at 0.375 inches minimum diameter. The GT087-12A produces a 0.088-inch-wide groove and extends to a maximum hole depth of 1.26 inches, making it well-suited for machinists and toolroom professionals working in tight-tolerance bore work. The 2.5-inch overall length and 3/8-inch shank diameter provide stable tool holding in standard collet and milling machine setups.

This grooving tool is intended for use in CNC lathes, turning centers, and manual lathes where internal retaining ring grooves must be cut with consistent width and depth. The left-hand cutting direction suits specific bore orientations and spindle setups where conventional right-hand tools are not appropriate. The 1.75-inch shank length provides solid grip in the tool holder, and the 0.11-inch projection keeps the cutting edge positioned accurately at the required groove depth. Typical users include CNC machinists, toolroom technicians, and precision parts manufacturers working with metals and engineered materials.

Key Features

• Submicron-grade solid carbide construction for wear resistance and edge integrity
• Left-hand cutting direction for specific bore and spindle orientations
• 0.088-inch groove width for standard retaining ring groove profiles
• Minimum bore entry diameter of 0.375 inches suits small to mid-range bore work
• Maximum hole depth of 1.26 inches accommodates a range of workpiece lengths
• 3/8-inch shank diameter fits standard collet and tool holder systems

Compatibility

Designed as an OEM-style replacement or direct-use grooving tool for internal retaining ring groove operations in bores with a minimum diameter of 0.375 inches and a maximum depth of 1.26 inches, using tool holders that accept a 3/8-inch round shank.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the 3/8-inch shank fully within the tool holder to the shank length before tightening. Power down and lock out the machine before changing or adjusting any cutting tool. Verify spindle direction matches the left-hand cutting orientation of this tool before running the machine.
