MOUNTING INSTRUCTIONS FOR ER-COLLETS PER DIN STD 6499 Assembling instructions: Insert groove of collet into eccentric ring of the clamping nut at the mark on the bottom of the nut. Push collet in the direction of the arrow until it clicks in place. Screw nut with collet onto toolholder. We recommend to tighten the nut with a torque wrench. Disassembling instructions: After the nut is unscrewed from the toolholder, press on the face of the collet while simultaneously pushing sideways on the back of the collet until it disengages from the clamping nut. Improper assembly can permanently destroy the concentricity of the collet and may result in a damaged clamping nut. Note: Only mount nuts with correctly inserted collets Never place the collet into the holder without first assembling it into the nut. Never clamp oversize tool shanks e.g. never use a 0 12-11 mm collet to clamp a 0 12.2 mm shank. Instead, use the next size up (in this example, a 0 13-12 mm collet). Insert tool the full length of the collet for best results if possible. However, never insert tool less than 2/3 of the collet bore length. Improper tool insertion can permanently deform the collet and will result in poor runout. / Maximum torque ER 16 ER 25 ER 32 ER 40 M22 x 1.5 M32 x 1.5 M40 x 1.5 M50 x 1.5 70 Nm 130 Nm 170 Nm 220 Nm Please observe the maximum torque indicated in the chart 266
