Steep Tapers 8° Steep taper adapter JIS B 6339 Design: - for highest cutting performance at HSS operations- high rigidity with vibration damping JIS ISO Form6339 B7388-2AD/BHPCHSC G 2,5 25.000 min-1 - universally applicable also with standard collets - high concentricity: 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 (except 241034) Note: l1 Matching collets see under 248910, 248920 and 248930 on page 24/514. d1 d 3 24 l2 241034 HAIMER, collet chuck Power ER, ultra short ST/Collet 241034 d1mm d3 l1 l2 LockingmmmmmmthreadST/Collet 241034 d1mm d3 l1 l2 Lockingmmmmmmthread 30/ER16  2.0 - 10 28 55 43 M12 30/ER32  2.0 - 20 50 55 53 M12 30/ER25  2.0 - 16 42 55 51 M12 — — — — — — — 241035 HAIMER, collet chuck Power ER, short ST/Collet 241035 d1mm d3 l1 l2 LockingmmmmmmthreadST/Collet 241035 d1mm d3 l1 l2 Lockingmmmmmmthread 30/ER16  2.0 - 10 28 80 43 M12 40/ER32  2.0 - 20 50  70 64 M16 30/ER25  2.0 - 16 42 80 51 M12 50/ER16  2.0 - 10 28 100 43 M24 30/ER32  2.0 - 20 50 80 53 M12 50/ER25  2.0 - 16 42 100 51 M24 40/ER16  2.0 - 10 28 70 43 M16 50/ER32  2.0 - 20 50 100 53 M24 40/ER25  2.0 - 16 42 70 51 M16 — — — — — — — 241036 HAIMER, collet chuck Power ER, long ST/Collet 241036 d1mm d3 l1 l2 LockingmmmmmmthreadST/Collet 241036 d1mm d3 l1 l2 Lockingmmmmmmthread 40/ER16  2.0 - 10 28 100 43 M16 40/ER32  2.0 - 20 50 100 53 M16 40/ER25  2.0 - 16 42 100 51 M16 — — — — — — — 241037 HAIMER, collet chuck Power ER, ZG130 ST/Collet 241037 d1mm d3 l1 l2 LockingmmmmmmthreadST/Collet 241037 d1mm d3 l1 l2 Lockingmmmmmmthread 50/ER16  2.0 - 10 28 130 43 M24 50/ER32  2.0 - 20 50 130 53 M24 50/ER25  2.0 - 16 42 130 51 M24 — — — — — — — 241038 HAIMER, collet chuck Power ER, overlong ST/Collet 241038 d 1mm d3 l1 l2 LockingmmmmmmthreadST/Collet 241038 d 1mm d3 l1 l2 Lockingmmmmmmthread 40/ER16  2.0 - 10 28 160 43 M16 50/ER16  2.0 - 10 28 160 43 M24 40/ER25  2.0 - 16 42 160 51 M16 50/ER25  2.0 - 16 42 160 51 M24 40/ER32  2.0 - 20 50 160 53 M16 50/ER32  2.0 - 20 50 160 53 M24 24/444 www.precitool.de
