Sandvik TLR-3078R 225G Grooving Carbide Inserts

Sandvik Coromant Top-Lok TLR-3078R profiling grooving insert, ANSI code TLR-3078R, is a right‑hand carbide Top‑Lok insert designed for profiling and grooving on turning centers. It uses an 1125‑grade carbide substrate with a PVD TiCrAlN+TiAlN coating for wear resistance and thermal stability in moderate-depth cuts, and the Top‑Lok interface provides quick, repeatable seating in compatible holders. The insert measures about 0.6338 in (16.1 mm) in length, 0.344 in (8.74 mm) in thickness, and 0.195 in (4.95 mm) in width, with a corner radius of 0.0779 in (1.98 mm) and a relief angle of 10 degrees, and it offers a maximum depth of cut of 0.15 in (3.81 mm). Rated for 1125‑grade wear resistance, its material grades span K, M, P, and S, giving versatility across common grooving and profiling applications. Designed for right‑hand cutting, this Top‑Lok profiling insert supports secure, repeatable performance in CNC lathes and turning centers, enabling precise grooving profiles and efficient chip control during multi‑pass operations. The carbide substrate and dual TiAlN‑based coating help maintain edge integrity during repeated passes, contributing to consistent part dimensions and surface finish in routine profiling tasks.
