TCMT 110208-B OS9501 Carbide Turning Insert

The TCMT 110208-B OS9501 is a precision carbide turning insert designed for finishing and semi-finishing of stainless steels and sticky materials. With its 60° triangular shape (T-type) and positive geometry, it offers low cutting forces, smooth chip evacuation, and excellent surface finish.

The OS9501 grade features a fine-grained carbide substrate with a PVD coating engineered for stainless steel applications. It provides excellent wear resistance and toughness, performing well in continuous cutting of 304/316 stainless steels, titanium alloys, and low-carbon steels. The B chipbreaker is optimized for stable chip control at medium to low feed rates, preventing built-up edge and improving tool life.

The 110208 designation specifies an 11 mm inscribed circle, 2.38 mm thickness, and a 0.8 mm nose radius, giving stronger edge strength than smaller radii, making it suitable for both finishing and light semi-finishing. Commonly used in precision engineering, medical machining, and aerospace applications, this insert ensures stable and repeatable results.
