      In stock

      Description

      Version:

      Exactly central ground point. Easy spot drilling and high shape accuracy of the centre hole. Sturdy due to short flutes.
      ≥ ⌀ 6 mm with HB drive flat.

      Application:

      Point angle 90° for spot drilling and countersinking in one operation when a drill of smaller ⌀ is used afterwards.

      Note:

      Use the speed for the actual hole ⌀ (not generally the speed for the drill outer ⌀).
