19 Piece Metabo Drill Set - HSS-R
Complete with the metal case you get 19 drill bits in the following sizes.
˜ 1 / 1.5 / 2 / 2.5 / 3 / 3.5 / 4 / 4.5 / 5 / 5.5 / 6 / 6.5 / 7 / 7.5 / 8 / 8.5 / 9 / 9.5 / 10 mm
Put simply, 1mm - 10mm in 0.5mm increments.
These jobber drills are good quality high speed steel and being produced / formed by the rolling process makes them good for hand drill use as they are more resilient to snagging.
HSS-R type drills will "lose their edge" more quickly than the ground or cobalt drills from Metabo, soif you are using a bench drill or lathe then choose the HSS- G (Ground) or the HSS-Gc (ground & cobalt) as these work well in "fixed" machines.
The HSS-R by Metabo are suitable for drilling commonly used steels, non-ferous metals, alloyed and non-alloyed cast steels. The R in HSS-R drill bits indicated that they are roll-milled bits. They have a strength of up to 900 N/mm2 tensile it is this method of production which gives the drills their toughness.
