Description

Collet chuck type ER, ISO 7388-1 (DIN 69871), Form AD/B, SK 40, balancing quality G6.3 12000 min-1 Design: Made of alloy case-hardened steel, with a core tensile strength of approx. 950 N/mm² and a hardness depth of min. 0.5 mm. Taper according to DIN 254. Taper angle tolerance: AT3 Taper surface roughness: Ra < 0.001 mm Hardened: 58 ± 2 HRC Application: For clamping tools with cylindrical shank in collets according to ISO 15488 (DIN 6499). For high-speed machining and heavy machining. Increased cutting performance due to higher speeds, feed rates and greater depth of cut. The increased running smoothness due to the low-vibration geometry ensures better surface quality and protects the tool, spindle and machine. Scope of delivery: Collet chuck complete with clamping nut.
