Friction Drill Holder Auxiliary Tools

01：Friction Drill：Using a standard tool holder will reduce the service life of the drill and the spring collet. Using a dedicated tool holder is more beneficial to extend the service life of the hot melt drill bit.
02：ER Collet Chuck：After drilling with a thermal drill, tapping can be done with a thermal tap, which can machine cold-formed threads.
Why choose extrusion taps:
The holes made by hot drilling are thinner due to the stretching of the hole wall. Using traditional cutting taps would damage the hole wall and reduce its strength. Therefore, it is recommended to use extrusion taps with hot drilling.
03：High-Strength Cooling Fin：A special aluminum alloy heat dissipation disk rapidly disperses the heat produced, ensuring that the equipment’s spindle is protected from damage caused by excessively high temperatures.
04：Handle：Manual Drills: MT2, MT3 Morse Taper or cylindrical shanks (Such as Ø16, Ø20mm).
CNC Machining Centers: BT30, BT40, HSK A-63 interfaces.
