Description

BT series Morse taper adapters with tang are manufactured from high-strength alloy steel with overall vacuum quenching and precision grinding, the essential connecting accessories for mounting tang-type Morse taper shank tools on BT spindle CNC machining centers.
  1. Tang design combined with rear drawbar thread provides double locking mechanism, completely eliminating tool loosening or falling off even under heavy cutting loads and high-speed rotation.
  2. Ultra-precision machining ensures ≤0.005mm runout accuracy, delivering perfect concentricity between the tool and spindle.
  3. Complete size range covers BT30, BT40, BT50 and BT60 spindle standards, compatible with MTB1 to MTB6 tang-type Morse taper shank tools.
  4. Multiple length options are available to meet different machining depth requirements and workpiece geometries.
  5. Standard 7/24 taper design is 100% compatible with all mainstream BT spindle CNC machine tools.
  6. Black oxide surface treatment provides excellent corrosion resistance and long-term durability in industrial environments.
