Notice
  • For blind holes, please note the extended drill tip (see dimension l3)!

  • The steps of the innovative point geometry drill gradually to achieve the required diameter. To achieve this, the chip is broken into small individual chips by several main cutting edges, thus ensuring optimal chip removal. The result is highly precise, circular drilling.

  • The use of several cutting edges at the same time enables very fast, comfortable working and a long service life.
