Micro 100 GS-018F Grooving Tool Bit 3/8 Shank Solid Carbide

Product Description

The MICRO 100 GS-018F is a single-point grooving tool bit designed for precision external and internal grooving operations on CNC and manual lathes. Built from solid carbide, it delivers the hardness and wear resistance needed for consistent, repeatable cuts in ferrous and non-ferrous materials. The shank measures 3/8 inch in height and 3/8 inch in width, with an overall length of 3 inches. The tip is 0.330 inches long and 0.018 inches wide, with a corner radius of 0.009 inches. This tool bit is suited for machinists and toolmakers working in production or job-shop environments.

The GS-018F is configured for neutral cutting direction, making it adaptable to a range of grooving setups without requiring a dedicated left- or right-hand holder. It fits standard GS-style tool holders and is appropriate for grooving, parting, and narrow-channel applications on small- to medium-diameter workpieces. Typical use cases include O-ring groove cutting, snap-ring groove cutting, and general-purpose grooving on bar stock in both manual and CNC turning operations.

Key Features

• Solid carbide construction for superior hardness and extended tool life
• Neutral cutting direction for flexible setup in GS-style holders
• 0.018-inch tip width for precise, narrow groove profiles
• 0.009-inch corner radius for clean groove geometry
• 3/8 x 3/8 inch shank fits standard GS-series tool holders
• 3-inch overall length provides adequate reach for typical turning setups

Compatibility

Designed for use with GS-style single-point tool holders accepting a 3/8 x 3/8 inch shank. Suitable for CNC and manual lathes used in general machining and production turning applications.

Installation Notes

Installation is performed by a qualified machinist or toolmaker. Secure the shank fully in the tool holder and verify proper seating and alignment before engaging the workpiece. Ensure the lathe spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing tool bits. Follow the machine manufacturer and tooling manufacturer guidelines for appropriate cutting speeds and feeds for the workpiece material.
