CD 7-28 Manual Core Bit Retipping Machine

Our most sold model.
The CD 7-28 works without electrical power, without noise, without sparks, waste or scrap. Cuts off the worn end and, at the same time, makes notches for the new segments - with exact distance.

The indexing disc gives you full control of the number of segments
required and full freedom to manufacture the right bit for an efficient work.

The depth of the segment seat can be adjusted - from 0,5 mm just enough to indicate the positioning of the segment - up to a three-side brazing slot for safer drilling in difficult materials. Also good when the steel is worn very thin.

The CD 7-28 is very easy and fast to operate. A drill bit with diameter 100 mm (4”) is ready within a minute. Use our magnets for the brazing and the whole core bit is retipped within the next few minutes.


  • Core bit Ø 38 - 700 mm (1-1/2” - 28”)
  • Core bit length 50 mm (2”) - Any length with extensions
  • Max steel thickness approx. 3.2 mm (1/8”)
