BT40-GT12-110L Telescopic Buffer Tapping Tool Holder Overload Torque Protection Machining Center Tapping Tool Holder Floating Telescopic

1、0.01mm body accuracy, the concentricity is high, the processing effect is good, the efficiency is improved, and the service life of the tool is prolonged 2、All tool holders contain high‑accuracy ball guide sleeves, reducing wear and have a higher concentricity, which can protect the product from excessively fast feeding and retraction of the product due to tapping, breaking of the tap and deformation under pressure control 3、The inner hole is finely ground to be bright, and it is ground by the self‑developed grinding stone 4、Advanced vacuum quenching furnace, can achieve carbonitriding, improve the hardness of the tool holder and the accuracy of the body 5、Improving tap life, reduce machine tool parameter requirements, improve thread accuracy and surface quality, torsion overload protection function 6、Provide micro‑compensation synchronous tapping, improving processing efficiency, optimization of extrusion taps, higher suitable for processing fine teeth and inch teeth Model: BT40-GT12-110L Material: High speed steel Purpose: CNC machining center tapping tool holder Tool Handle Length: Approx. 110mm / 4.3in Size of Chuck: Approx. 19mm / 0.7in Maximum Diameter of Handle Taper: Approx. 44.45mm / 1.8in Applicable Chuck: GT12 TC312 G3 Function: Used for clamping during thread processing. The telescopic tapping tool holder can shrink back and forth by 5mm through the internal protection mechanism, which can protect the tap when it is overloaded and stopped. 1 x Tapping Holder
