kwb 5 piece HSS bi metal hole saw set Ø 25, 32, 40 and 51 mm with progressive vario toothing, high precision, 1/4" hexagonal shank, 38 depth of cut centre bit

HSS TENDER: The high-quality HSS toothing of the hole saws for metal is suitable for machining unalloyed and alloyed steels, non-ferrous and light metals, sheet steel, aluminium, bronze, copper, plastic, acrylic, plasterboard and wood. PROGRESSIVE VARIO-TOOTHING: The progressive vario-toothing of the kwb hole saws made of bi-metal ensures accelerated chip removal and thus a longer service life due to lower heat generation during cutting. HIGH PRECISION: Due to the stable, resistant hole saw bodies and the 6 mm centre drill of the core bit set made of high-quality M2 steel, a clean cut and high precision is possible. 1/4" HEXAGONAL SHANK: The 1/4" hexagonal shank of the HSS hole saw set is not only suitable for rotary and impact drills, but also for cordless screwdrivers. 38 MM CUTTING DEPTH: With the hole saws for plastic in diameters of 25, 32, 40 and 51 mm, it is possible to cut holes in material thicknesses of up to 38 mm. 6 MM CENTRE DRILL: The 5-piece set includes a centre drill for hole saws from kwb made of high-quality HSS steel with a diameter of 6 mm and a length of 75 mm.
