Replaceable Head Type MULTI-DRILLs

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

New l Drilling Depths 1,5 ~ 12 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

New l 3 different types of head for general and smooth cutting (MTL type, MEL type)

and new MFS type for drilling in non-flat surfaces.

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

Specially treated toughened steel body to resist wear and rust

Through coolant holes positioned to optimise coolant pressure and direction.
