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 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

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

Technical data subjects to change without prior notice.

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)

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
