THINBIT 3 Pack SGI039D2 Grooving Insert 0.039″ x 0.100″ Carbide

Description

Product Overview

The THINBIT SGI039D2 is a high‑performance internal grooving insert designed for demanding machining applications. With a compact 0.039″ width and a 0.100″ depth capability, this insert provides the precision needed for tight‑tolerance features such as o‑rings, snap rings, and piston rings. Constructed from uncoated DURA‑MAX 2000 carbide, the insert offers exceptional wear resistance and retains a sharp cutting edge even after extended use on steel, cast iron, and stainless steel. Its interrupted cut geometry reduces chip buildup and improves chip evacuation, while the sharp corner design ensures clean, burr‑free finishes. The insert is supplied in a convenient three‑pack configuration, allowing users to maintain continuous production without frequent tool changes. Dimensions of the insert are 0.65 x 0.07 x 0.24 inches, making it compatible with a wide range of small‑series toolholders.

Usage

This grooving insert is ideal for internal machining tasks where space is limited and precision is critical. It excels in applications that require cutting within 1/16″ of a collet face or the shoulder of a larger diameter component. Typical use cases include machining of internal grooves for sealing rings, creating slots for snap‑fit features, and parting operations up to .200″ deep. The insert performs reliably on a variety of materials, from hardened steel to cast iron and stainless steel, making it a versatile choice for automotive, aerospace, and general manufacturing environments. Users should pair the insert with compatible small‑series toolholders and ensure proper coolant flow to maximize tool life and surface finish quality.
