THINBIT LGI076D2FR Grooving Insert 0.076″ Width Carbide Radius

Description

Product Overview

The THINBIT LGI076D2FR grooving insert is engineered for high‑precision machining of steel, cast iron, and stainless steel. With a compact 0.076 inch (1.93 mm) width and a maximum depth of 0.114 inch (2.90 mm), this insert provides the flexibility needed for tight‑tolerance groove creation in a variety of industrial applications. Constructed from DURA MAX 2000 uncoated carbide, the insert delivers exceptional hardness and wear resistance, ensuring a long tool life even under demanding cutting conditions. The full‑radius geometry, combined with interrupted cuts, reduces cutting forces and minimizes chip adhesion, resulting in smoother finishes and reduced tool wear. Designed to fit Large series toolholders, the LGI076D2FR offers seamless integration into existing machining setups, allowing users to quickly upgrade their capabilities without extensive re‑tooling.

Key specifications include a product dimension of 0.72 x 0.13 x 0.24 inches, a model designation of LGI, and a manufacturing pedigree from Kaiser Tool Company, Inc., a trusted name in cutting tool technology. The insert’s interrupted cut design enables efficient chip evacuation, which is critical when machining deep grooves or parting operations. Its uncoated carbide composition provides a balance of toughness and edge retention, making it suitable for both high‑speed and heavy‑cut applications. The insert’s geometry is optimized for plunge grooving, allowing operators to achieve consistent groove depths with minimal vibration.

Beyond its technical attributes, the LGI076D2FR is backed by a robust performance record, as evidenced by its ranking among the top face grooving inserts on major e‑commerce platforms. This reputation is built on reliable performance, ease of use, and the ability to deliver clean, repeatable results across a wide range of material types. Whether you are producing o‑rings, snap rings, piston rings, or other precision components, this insert offers the accuracy and durability required for high‑volume production environments.

Usage

The LGI076D2FR insert excels in applications that demand precise groove dimensions and high surface quality. It is particularly well‑suited for machining o‑rings, snap rings, and piston rings where the groove must be positioned within 1/16 inch of the collet face or shoulder of a larger diameter component. The insert’s ability to plunge directly into the workpiece enables rapid material removal while maintaining tight tolerances, making it a preferred choice for manufacturers focused on efficiency and repeatability.

In addition to groove creation, the insert can be employed for parting operations up to 0.228 inch (5.79 mm) deep, providing versatility for secondary machining steps. Its interrupted cuts facilitate effective chip breakage, reducing the risk of chip re‑adhesion and improving overall machining stability. The insert’s compatibility with Large series toolholders means it can be used on a variety of CNC machines, including vertical and horizontal milling centers, as well as specialized grooving stations.

When machining stainless steel, the uncoated carbide material offers sufficient hardness to resist work hardening while delivering a clean edge. For cast iron applications, the insert’s geometry helps to mitigate the abrasive nature of the material, extending tool life. Operators can expect consistent performance across a range of cutting speeds, feed rates, and coolant conditions, thanks to the insert’s robust design and material composition.
