BT Milling Cutter Holder with ER Collet Set
DUAL CONTACT Milling Cutter Taper BT for Collet ER 2.5G 25,000 RPM
BT toolholders are 7/24 taper holders for CNC machining centers, built to clamp cutting tools securely and transmit torque reliably for milling, drilling, and high-precision operations. Acting as the interface between the spindle and the cutter, they support stable machining, consistent tool positioning, and reduced vibration—key factors for dimensional accuracy and surface finish.
This collection covers multiple BT holder types, including collet chucks, end mill holders, shell mill arbors, drill chucks, and options for threaded or hydraulic-style clamping systems, with selections suited for high-speed machining and balancing requirements. You’ll find solutions from Yg, Kemmler, and Vertex, focusing on low runout, correct taper geometry, durable construction, and dependable repeatability during tool changes.
BT holders are widely used by CNC operators, manufacturing engineers, and QC teams in industries such as aerospace, mold & die, and general metalworking, where toolholding rigidity and accurate concentricity directly impact cycle time, tool life, and part quality.
