Dimensions of Solid Carbide Drills Conforming to DIN_®

Note:

Solid carbide drills from KENNAMETAL HERTEL conform to the current standards d₂ for suppliers of drilling tools, DIN6537K and DIN6537L.

As only tools of 3 x d and 5xd are covered in

this standard, an internal standard has been

specified for a length range of 8xd in order

to expand the range of applications.
