Alpha SM16ST 16 piece ONSITE Plus Impact Step Tip Drill Set

The Alpha SM16ST is a 16 piece set of ONSITE Plus impact step tip drill bits from 4.0mm to 13.0mm, with two 6.0mm bits. The bits are fully ground M2 HSS with a 135° split point and a 1/4" quick change shank (manufacturer-stated).

The sizes are 4.0, 4.5, 5.0, 5.5, 6.0 (two of them), 6.5, 7.0, 7.5, 8.0, 8.5, 9.0, 9.5, 10.0, 12.0 and 13.0mm. Alpha lists the same step tip bits as singles, with the overall length and flute length of each size in the catalogue.
