For producing high-quality and smooth tenons, e.g. for hand rail junctions in making stairs or for the production of wood dowels, such as knothole dowels or screw covers. Due to optimized cutting edge geometry, low energy input required, especially in hardwood. Extremely long lifetime. Used with Forstner bits and hinge boring bits.

  • CNC ground Offers higher precision for improved quality of cutting edge geometry and diameter tolerances.
  • Ground interior diameter The smallest possible diameter tolerances and the slightly conical shape of the cutting insert ensure optimum quality of the plugs.
  • Large withdrawing zone Enables easy withdrawal of plugs and variable plug lengths possible.
  • Perfect concentricity Prevents unbalance (no vibrations) and ensures precise working.
  • Burnished steel Chemical corrosion protection for a long service life.


Precision-cut cutting edge geometry made of Highspeed Steel, multi-cut, with peripheral cutting edge and cylindrical shank. For diameter up to 32mm: shank 13x50mm. From diameter 33mm: shank 16x50mm.
