Power Shrink Chuck, DIN ISO 7388-1, SK50
(formerly DIN 69871)
Quality pass
Chuck fine balanced G2.5 at 25.000 rpm
All functional surfaces fine machined
Taper tolerance AT3
Coolant supply form AD/AF
Shrink fit chuck suitable to all inductive shrink fit units.
The Power Shrink Chuck is the shrink fit chuck for highest machining capacity in high-speed manufacturing. The optimized design combines high rigidity with dampening vibrations, therefore giving more protection to machines, spindles and tools.
  • Increased machining capacity due to higher spindle speed, higher feed and larger cutting depth
  • Shorter processing times
  • Quieter running, therefore better surface quality and protection of tools, spindles and machines
  • Higher machining accuracy
  • With threaded holes in order to balance with balancing screws
  • Cool Jet bores that can be sealed included
  • High rigidity
  • Slim at the tip
  • Dampen vibrations
  • High clamping force
  • Equally suited to high-speed manufacturing and heavy milling
  • Universal usage, saves space in tool magazine
Scope of Delivery
  • With backup screw
HAIMER TIP
For RPM higher 8000 U/min we recommend the optional cooling system Cool Flash. (on request)
The most important features:
  • 1. High runout accuracy (< 0.003 mm)
  • 2. Low tendency towards vibrations by optimised outer geometry
  • 3. Slim design at the top
  • 4. Very rigid shank
  • 5. Standard with Cool Jet (can be re-sealed)
  • 6. Dirt groove in the clamping bore for safe clamping force
  • 7. Safe-Lock (optional)
Machining example Power Shrink Cuck
  • Milling - Ø: 16 mm; n = 13.000 1/min, Feed rate: vf = 5,2 m/min
  • Right: Power Shrink Chuck (Length: A = 160 mm, cutting depth: ap = 3,6 mm)
  • Left: Standard Shrink Chuck (Length: A = 160 mm; Cutting depth: ap = 1,8 mm)
Cool Jet (optional)
  • Optimized coolant bores, aimed at center
  • Coolant directly to the cutting edge
  • Extended tool life up to 100%
  • Higher reliability of cutting process
  • No more balls of chips on tool
  • Cool Jet starting from shank diameter 6 mm
Cool Flash (optional)
  • Optimized coolant bores with coolant outlet through slots
  • Coolant directly to the cutting edge
  • Extended tool life up to 100%
  • No more balls of chips on tool
  • Optimized runout accuracy! No additional unbalance! No disturbing clearance!
  • Cool Flash available for shank diameter 6 - 25 mm
