THINBIT SGI030D2FR 3 Pack 0.030 x 0.090 in Carbide Grooving Insert

Description

Product Overview

The THINBIT SGI030D2FR 3‑pack is engineered for high‑precision grooving applications across a broad range of metalworking environments. Each insert measures 0.030 × 0.090 in, offering a compact footprint that fits tightly into Small series toolholders while delivering a full‑radius cutting edge that reduces vibration and extends tool life. Constructed from uncoated DURA‑MAX 2000 carbide, the inserts provide exceptional hardness and wear resistance, making them suitable for machining steel, cast iron, and stainless steel. The interrupted‑cut geometry enables rapid chip evacuation and minimizes heat buildup, which translates into cleaner cuts and longer intervals between tool changes. With a total of three inserts per pack, users gain flexibility to tackle multiple passes or replace worn inserts without interrupting production flow.

Usage

These grooving inserts excel in applications that demand tight tolerances and consistent surface finishes. Typical use cases include machining o‑rings, snap rings, piston rings, and other cylindrical components where the cut must be positioned within 1/16 in of a collet face or shoulder. The design supports plunge grooving to depths of up to 0.090 in, and it can also be employed for parting operations on stock up to 0.180 in thick, providing versatility for both fine detail work and larger material removal. The inserts perform reliably in high‑speed machining centers, CNC lathes, and manual turning setups, making them a valuable asset for automotive, aerospace, and general manufacturing shops that require precision and repeatability.

FAQ

What materials can these inserts machine?

The SGI030D2FR inserts are suitable for machining carbon steel, alloy steel, cast iron, and a wide range of stainless steel grades. Their carbide composition provides the hardness needed to maintain cutting edges even on tougher alloys, while the interrupted‑cut geometry helps manage heat and chip flow across all these materials.

Can the inserts be used for parting operations?

Yes. Although primarily designed for grooving, the inserts can also perform parting cuts on stock up to 0.180 in thick. The full‑radius edge and carbide durability allow the tool to handle the additional load, making it a versatile choice for shops that need both grooving and parting capabilities from a single insert set.

What toolholder sizes are compatible?

The inserts are optimized for Small series toolholders, which typically range from 0.125 in to 0.250 in in diameter. This compatibility ensures a secure fit and stable cutting conditions, even at high spindle speeds. Users should verify the specific holder model to confirm the exact fit.

How does the interrupted‑cut design benefit the machining process?

Interrupted cuts create gaps in the cutting edge that allow chips to escape more easily, reducing the risk of chip re‑cutting and heat buildup. This design improves overall cutting efficiency, extends insert life, and helps achieve smoother surface finishes, especially when working with materials that tend to produce long, continuous chips.

What support does THINBIT offer after purchase?

THINBIT provides a suite of resources, including downloadable technical data sheets, CAD drawings, and compatibility guides. Customers also have access to a dedicated engineering support line for troubleshooting, setup advice, and performance optimization. Our warranty covers manufacturing defects, and we strive to resolve any issues promptly to keep your production running smoothly.
