Power Collet Chuck
DIN 69893-5 · HSK-E25

For clamping tools with cylindrical shank in HAIMER Power Collets and ER collets according to ISO 15488.

Low cutting forces at highest rpm are characterizing the micro machining (die & mold, medical engineering, micro mechanical engineering). The Power Collet Chuck is the collet chuck for the highest machining capacity in high-speed manufacturing. The optimized design with better construction combines high rigidity with vibration dampening features, giving more protection to machines, spindles and tools. The universal Power Collet Chuck is a unique high performance chuck that can also be used with standard collets. The slim and short design of the all new HSK–E25 series from HAIMER - which is well known from the HAIMER Mini Shrink tool holders – is perfectly suitable for the requirements of micro machining.

High runout accuracy: 3 μm at 3 × D with Haimer Power Collets
Also for standard collets ER according to ISO 15488 (formerly DIN 6499)
High rigidity
Smoother running thanks to vibration absorbing geometry, therefore better surface quality and protection of tools, spindles and machines
Increased machining capacity due to higher spindle speeds, higher feed rates and larger cutting depths
Shorter processing times, higher machining accuracy, high clamping force
Equally suited to high-speed manufacturing
