d1 d3 Steep Tapers 8° Steep taper adapter DIN 69871 Design: - for highest cutting performance at HSS operations DIN Form G 2,5 G 2,5 - high rigidity with vibration damping 69871 AD/B 25.000 min-1 30.000 min-1 - high concentricity of 0.003 mm at 3 × D with Haimer Power Collets - also for standard collets ER to ISO 15488 (Attention: When used with standard collets the I1dimension is longer) - higher running smoothness thanks to vibration absorbing geometry, therefore better surface quality - increased chipping capacity due to higher speed, greater feed and greater cutting depth - shorter machining times - better dimensional stability - high clamping power - ideally suited for HSS and heavy-duty machining - with threaded holes for balancing screws - SK40 balanced G2.5 30,000 min-1 - SK50 balanced G2.5 25,000 min-1 Note: - matching collets see under 248910, 248920 and 248930 on page 24/514 - fitting tightening bolts see under 246542 on page 24/498 24 l2 l1 240712 HAIMER, collet chuck HP, short ST/Collet 240712 d1mm d3 l1 l2 LockingmmmmmmthreadST/Collet 240712 d1mm d3 l1 l2 Lockingmmmmmmthread 40/ER16 2.0 - 10 28 70 43.0 M16 50/ER16 2.0 - 10 28 70 43.0 M24 40/ER25 2.0 - 16 42 70 61.5 M16 50/ER25 2.0 - 16 42 70 62.0 M24 40/ER32 2.0 - 20 50 70 62.0 M16 50/ER32 2.0 - 20 50 70 62.5 M24 240714 HAIMER, collet chuck HP, long ST/Collet 240714 d1mm d3 l1 l2 LockingmmmmmmthreadST/Collet 240714 d1mm d3 l1 l2 Lockingmmmmmmthread 40/ER16 2.0 - 10 28 100 43.0 M16 50/ER16 2.0 - 10 28 100 43.0 M24 40/ER25 2.0 - 16 42 100 61.5 M16 50/ER25 2.0 - 16 42 100 62.0 M24 40/ER32 2.0 - 20 50 100 62.0 M16 50/ER32 2.0 - 20 50 100 62.5 M24 240716 HAIMER, collet chuck HP, ZG130 ST/Collet 240716 d1mm d3 l1 l2 LockingmmmmmmthreadST/Collet 240716 d1mm d3 l1 l2 Lockingmmmmmmthread 50/ER16 2.0 - 10 28 130 43.0 M24 50/ER32 2.0 - 20 50 130 62.5 M24 50/ER25 2.0 - 16 42 130 62.0 M24 — — — — — — — 240718 HAIMER, collet chuck HP, overlong ST/Collet 240718 d 1mm d l l Locking312mmmmmmthreadST/Collet240718 d 1mm d l l Locking312mmmmmmthread 40/ER16 2.0 - 10 28 160 43.0 M16 50/ER16 2.0 - 10 28 160 43.0 M24 40/ER25 2.0 - 16 42 160 61.5 M16 50/ER25 2.0 - 16 42 160 62.0 M24 40/ER32 2.0 - 20 50 160 62.0 M16 50/ER32 2.0 - 20 50 160 62.5 M24 www.precitool.de 24/419
