                                                                SMD Type

General Features

Fast accurate and ideal for drilling steels, this newly developed drill
from SUMITOMO gives similar hole accuracy to that of regrindable
drills renowned within the industry as being the ultimate hole making
tool.

Advantages           l Available in diameters ranging from 12,0~42,5mm
                     l Drilling Depths to 8 x Diameter
                     l Optimised heat dissipation via precisely located coolant holes
                     l Maximised rigidity from newly developed clamping system
                     l High performance drilling of precision holes from solid
                     l 2 different type of head for general and smooth cutting

The newly developed tungsten carbide substrate                                               Edge security comes from replaceable drilling
with it’s ultra hard smooth coating proved that                                              heads bolted to fixed radial serrations which
against competition users can expect to see                                                  provide a rigid and precise clamping platform.
