Ultra flexible – FEIN HM ULTRA. More quality in every way.
Ultra long lasting, ultra efficient, Ultra flexible – FEIN HM ULTRA. The core drill bits with innovative cutting geometry.

Better in every way.

Ultra durable:
Ultra durable: Up to 100% longer life thanks to a new cutting geometry. An innovation that pays off in terms of durability and work quality: on the one hand, the load on the individual cutters has been reduced considerably, and on the other the stress is equally distributed. The result: FEIN HM ULTRA-core drill bits last longer than traditional TCT core drill bits.

Ultra efficient:
Ultra efficient: the innovative cutting geometry ensures that the chips removed are a uniform size. Material removal is thus optimised for top quality work results. The result: Up to 20% more machining performance thanks to simultaneous meshing of the drill. In other words: with FEIN HM ULTRA-core drill bits you get more work done per hour – and improve your effi ciency.

Ultra flexible:
Ultra flexible: FEIN HM ULTRA-core drill bits are highly specialised: for optimal core drilling results. And what is more, in all current types of steel, including high quality steel and non ferrous metals. A FEIN HM ULTRA excels through precise boring – even when not used with a FEIN core drill. And of course, there is the FEIN HM ULTRA-core drill bit, with its super fast FEIN QuickIN fitting and with the M 18-FEIN thread and Weldon fitting.

Ultra comfortable:
Ultra comfortable: The combination of HM ULTRA and QuickIN offers in every respect the highest level of core drilling comfort. Changing tools with the QuickIN quick-change system is ultra comfortable and time saving: Insert the core drill bit, click it into place – ready.

Ultra safe:
Ultra safe: Sharp cutting and powerful – the FEIN HM ULTRA provides greater safety: its innovative cutting geometry with rear cutting keeps the chips short and removes them more quickly from the cutting hole. This has two benefits: You have a better view of the cutting position and work more safely.

Considerably more cost-effective than normal 'full' drilling

For drilling large diameters up to Ø 65 mm, maximum

For drilling thick materials up to Ø 50 mm, maximum

No centring and rough-drilling required

Better surface quality, no burr formation

Clean drill hole

Also suitable for overlap drilling
