  • Cool Jet, can be sealed

Power Shrink Chuck with Safe-Lock™
DIN 69893-1 · HSK-A125

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 internal groove in the clamping bore
  • With threaded holes in order to balance with balancing screws
  • With Cool Jet bores that can be sealed (Thread M4) and 6 bores
  • Higher coolant flow rate due to optimized coolant bores
  • Cooling with Cool Flash for an extra charge
  • Safe-Lock™ pull out protection included

The long versions (A = 160 and 200 mm) with slim tips are especially versatile to use.

  • 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

Features Power Shrink Chuck

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)

Safe-Lock™  for Shrink Fit Chucks

Safe-Lock™ pull out protection

  • Highly accurate clamping due to shrink fit technology
  • High torque due to form closed clamping
  • No loss of accuracy
  • No pull out and no spinning ot the tool
  • Groove on tool shank is directed so that the tool will be pulled into the chuck (depending on direction of rotation)
Cool Jet for Shrink Fit Chucks

Cool Jet

  • 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 Flash

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
Machining example Power Shrink Chuck vs. Standard Shrink Cuck

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)
