U3M collets clamp the tool from the outside with high centering precision (TIR typically \u0026lt;0.01 mm) — significantly superior to a standard self-tightening chuck for precision milling and drilling operations.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the difference between 14.0 mm collets and the other sizes in the set?\u003c\/summary\u003e\n\u003cp\u003eEach collet is specific for the indicated tool shank diameter — a 14.0 mm collet only accepts tools with an exactly 14.0 mm shank. \"Approximate\" collets cannot be used (e.g., an 8 mm collet for a 6 mm tool). The complete set (6, 8, 12 mm) covers the most common shank diameters for end mills in wood and composite materials on machines of this range.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow do you mount and dismount a collet in the collet holder?\u003c\/summary\u003e\n\u003cp\u003e1) Insert the collet into the collet holder cone (it should click into place). 2) Insert the tool into the collet. 3) Tighten the collet nut with the appropriate wrench until it is firm — no further, to avoid deforming the collet. To dismount: loosen the nut and use a brass hammer (never steel) to extract the collet from the conical housing. Never force it with a hammer directly on the nut.\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.
