      Tap extension with HB flat

      In stock



      h6 shank with Weldon flat for use in Weldon/shrink-fit chucks or hydraulic chucks.
      • Long and extra long version.
      • The front end of the extension acts as a collet. The collet is clamped to the tap by tightening the knurled clamping nut.
      • The torque is transmitted via the drive square.
      • The rear of the extension is to DIN, so that the extension can be mounted in quick-change tapping collets or ER tapping collets with a square drive.


      For tapping in inaccessible places such as recesses, offsets, sharp edges on jigs, extremely deep internal threads or directly into casting walls.
