International Tools HSS and HSS-E twist drill sets, up to 220 pieces
International Tools twist drill sets bundle HSS drills in a cassette, with every common diameter in half-millimetre steps to hand, for the workshop, the workbench and the service van.
Start with the range. Sets from 1 to 10 mm cover most assembly and maintenance work, sets from 1 to 13 mm go up to the largest size that fits an ordinary chuck. Each size comes in steps of 0.5 mm. Large cassettes of 170 and 220 pieces hold several drills of the small sizes, which break or wear fastest. The 220-piece cassette adds drills of 3.3 and 4.2 mm, the core hole sizes for M4 and M5 threads.
Then choose the grade. Rolled HSS drills suit general work in steel and non-ferrous metals. The ECO PRO HSS sets are ground more precisely, and the ECO PRO HSS-E set to DIN 338 holds up better in stainless steel. These sets are part of the International Tools sets and kits. If you cut threads after drilling, the International Tools thread cutting and hand tap sets match these core hole sizes.
