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 Available in diameters ranging from 12,0 42,5mm New Drilling Depths 1,5 12 x Diameter Optimised heat dissipation via precisely located coolant holes Maximised rigidity from newly developed clamping system High performance drilling of precision holes from solid New 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 holes with tolerances similar to that of reaming and tool life almost doubled. Through coolant holes positioned to optimise coolant pressure and direction Edge security comes from replaceable drilling heads bolted to fixed radial serrations which provide a rigid and precise clamping platform. Specially treated toughened steel body to resist wear and rust Drilling Precision I Application Example Drill: 018,0mm Work material: C50 Conditions: vc = 70 m/min, f = 0,25 mm/rev doc = 38 mm (through), Water soluble SMD-MultiDrill k 1 ft’ JM Conventional Brazed Drill 3 Times Life Fixed at 70pcs/reg.
