Sutton Viper D105 2.0mm HSS Jobber Drill Bit

The Sutton Viper D105 is a 2.0mm jobber drill bit made from high speed steel and sold carded as a single bit. It is part of the Sutton Viper range, developed for the trades person and the home handy person and built for machine and hand held drilling in a wide range of ferrous and non ferrous materials, including steel, aluminium, brass, wood and plastics. The Viper point is a 118 degree split point that self centers as it starts, so the bit stays on the mark and needs less pressure to cut.

Frequently Asked Questions

What is a 2mm drill bit used for?

A 2mm HSS bit is a common pilot drill for small machine screws and self tappers, and it opens out to a 2.4mm or 3mm tapping size for many thread series. It is also handy for drilling thin sheet and for starting holes that a larger bit will finish.

Do I need to centre punch first?

Usually not. The 118 degree split point bites into the surface and stops the bit walking, so on most metals you can start straight onto the mark. On a polished or hardened surface a light centre punch still helps.

How long will a 2mm HSS bit last?

With a sensible feed and a little cutting oil on steel, a jobber bit like this lasts a long time in normal use. Dullness shows as the bit rubbing and smoking; stop and resharpen or replace rather than forcing it.

Can I use it in an impact driver?

No. Impact drivers are for driving fasteners, not drilling. Use a corded or cordless drill; the small shank needs a chuck that grips it without wobble.
