HSS Drill Bit Set

Sets of HSS twist drill bits in a case, for drilling steel, aluminium and plastic. Pick the set by number of pieces and size range.

• High speed steel (HSS)
• Sets from 6 to 25 pieces, with sizes from 1 mm up to 13 mm depending on the set
• The 6-piece set has 2, 3, 4, 5, 6 and 8 mm bits with straight shanks for a standard drill chuck

Drill steel slowly, with steady pressure and a drop of oil. Too much speed overheats the tip and blunts it before the hole is through.
