DORMER HSS Jobber Drill A108 UAE
Features
The DORMER A108 is a fully ground HSS (High Speed Steel) jobber-length twist drill built for general-purpose hole making in steel, cast iron, aluminium, and other common workshop materials. Manufactured to DIN 338 dimensional standards, the A108 range delivers a precision-ground 118° conventional point for reliable self-centering on flat and lightly curved surfaces, minimising walking on start-up. Bright/polished HSS construction gives good wear resistance and edge retention across a wide range of cutting speeds, while the standard jobber flute length balances rigidity with chip clearance for clean, efficient drilling. This listing also includes the 12.50mm size in a stainless-finish variant, offering improved surface finish and corrosion resistance for use on stainless steel and other tougher alloys.
How to Use
Select the drill diameter matching your required hole size and mount it in a standard 3-jaw chuck or collet. Centre-punch the workpiece before drilling to prevent the point from wandering, and run the drill at a speed appropriate to the material being cut — slower speeds for harder metals such as stainless steel, faster speeds for softer materials like aluminium. Apply steady, even feed pressure and use cutting fluid or coolant on steel and stainless steel to extend tool life and improve finish. Clear chips periodically on deeper holes to avoid binding.
