FOR THE MANUFACTURY OF COOLANT FED CUTTING TOOLS
 
ST
Standard geometry adapted to the production of welded or straight shank drills. Offers hole diameter and spacing that are optimized for standard drills.

FE3 80%
Geometry reduced to 80% of standard CHD. The hole diameter and spacing are slightly reduced to match oversize straight shank (in particular standard shanks according to DIN 6535) with or without a whistle notch/flat, or for the production of step tools.

FE2 65%
Geometry reduced to 65% of standard size. The greater reduction in hole diameter and center distance allow the production of more specific step tools in one piece, or of standard oversized straight shank tools with or without a flat/whistle notch.

FE1 50%
Geometry reduced to 50% of standard size. The particularly small size of the holes and the very narrow center distance are designed for special geometries, multi-step tools, aerospace drills, standard shanks, etc.. It allows the construction of the most complex tools in one piece.
