The clamping force is generated by manually rotating the collar: sufficient for standard drilling. For heavy drilling (Ø \u003e20 mm on steel) or operations that generate reverse torque (tapping), a geared chuck provides superior grip compared to a keyless chuck.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eB16 connection — compatibility?\u003c\/summary\u003e\n\u003cp\u003eThe B16 connection is the most common standard short taper (Jacobs) found on pillar drills. Verify the short taper code of your machine's chuck before purchasing.

The reverse torque generated during tap extraction can loosen the chuck's grip, causing the tap to be released. For tapping on a drill, use tapping chucks with safety clutches specifically designed 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 days shipping.
