Special Features

  • Bar holders are made of high-quality steel and coated with a strong durability. The carbide inserts have a moisture-proof and rust proof tin coating, which can be used for a long time.
  • 3/4" Shank Diameter: Designed for robust boring operations, fitting a wide array of lathe machines with a 3/4" tool holder.
  • The round shanks offer versatility, allowing operators to set both positive and negative rake angles. Precision-engineered chip breakers prevent messy shavings for cleaner cuts and smoother finishes.
  • The carbide inserts are indexable, meaning you can simply rotate to a fresh cutting edge when one side dulls. No chuck/toolpost removal needed, keeping your machining continuous with zero disassembly time.
  • Strategic TCMT21.51 (all-purpose) & TCMT221 (heavy-cut) combo handles varied jobs. Perfect for lathe/boring mill operations: facing, internal turning, contouring, and semi-finishing holes. Includes rugged foam case to organize inserts and prevent damage during transport.
