Sandvik L166.0L-11MM01-175 1020 T-Max U-Lock Carbide Grooving Insert (10pc)

The Sandvik Coromant L166.0L-11MM01-175 1020 is a new, left-hand carbide grooving/parting insert for the T-Max U-Lock system, grade 1020, with a cutting width of 1.75 mm and a cutting depth capacity suited for small-diameter grooving operations. Grade 1020 is an uncoated cemented carbide grade optimized for machining cast iron (K), stainless steel (M), and low-alloy steels (P) at moderate cutting speeds; the gold appearance visible in the photos is characteristic of the 1020 substrate surface finish rather than a PVD or CVD coating layer. Per the package label, recommended cutting conditions include ap = 1 mm (0.039 in) with vc = 110–125 m/min (360–415 sfm) depending on workpiece material (M: 110 m/min/360 sfm at 200 HB; P: 125 m/min/415 sfm at 175 HB; K: 110 m/min/360 sfm at 245 HB). This insert is designed for Sandvik T-Max U-Lock toolholders in the L166 series and is suited for external grooving, parting, and shallow profiling on CNC lathes. The package contains 10 inserts (qty 023 per label = pack of 10), made in Sweden.
