Sandvik TLB-3R H13A Carbide Grooving Insert (10 Pcs)

The Sandvik Coromant TLB-3R in grade H13A is a new, uncoated cemented carbide grooving/parting insert from the T-Max Q-Cut and CoroCut system family, designed for use in T-Max Q-Cut blade-style toolholders. Grade H13A is an uncoated fine-grain cemented carbide optimized for ISO H (hardened steel, cast iron) and ISO N (non-ferrous/aluminum) applications, offering very high edge sharpness, low cutting forces, and excellent surface finish at high cutting speeds. The TLB-3R designation identifies a right-hand, 3 mm wide grooving blade insert with the characteristic double-ended, parallelogram profile visible in the photos, featuring a central locating notch for precise blade-to-holder registration. ISO material applicability as confirmed on the box label spans P, M, K, N, S, and H work materials, making this insert versatile across steel, stainless, cast iron, non-ferrous, superalloys, and hardened materials, though H13A is most competitive in non-ferrous and hardened workpiece applications. This factory-sealed box of 10 inserts carries Sandvik Coromant order number 8G10846201 (internal reference 80009233) and is suited for shallow grooving, parting, and turning operations on CNC lathes using compatible T-Max Q-Cut blade holders.
