Reisser HSS Long Series Drill Bit 5.5mm x 139mm

Reisser HSS Long Series Drill Bit 5.5mm x 139mm

Reisser 145139 High-Speed Long Series HSS Drill Bits have a 5.5mm diameter, 139mm length and a working length of 91mm. Reisser HSS Drill Bits expertly drill steel, aluminium, plastic pipes and profiles because of their 135º split point which centres accurately without the need to centre punch. These bits are also fully ground which gives less tolerance and longer life than roll forged bits and have a reinforced core, giving greater fracture stability. Reisser recommends always pre-drill with a shorter drill of the same diameter to help prevent flexing and breakage.
