The clamping force is generated by manually rotating the collar: sufficient for standard drilling. For heavy-duty drilling (Ø \u003e20 mm on steel) or operations that generate reverse torque (tapping), a geared chuck ensures a superior hold to a keyless chuck.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eMK 4 Taper — what machine is it compatible with?\u003c\/summary\u003e\n\u003cp\u003eThe MK 4 taper fits directly into the machine's spindle with an MK 4 Morse taper seat. Please check that your machine's seat matches the indicated taper. For machines with a different diameter seat, use extension\/reduction sleeves.

The reverse torque generated during tap extraction can loosen the chuck's grip, causing the tap to be released. For tapping on a drill press, use tap holders with specific safety clutches for tapping.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDelivery times?\u003c\/summary\u003e\n\u003cp\u003eOriginal spare parts available with 3–5 working day shipping.
