Sutton Viper D105 1.5mm HSS Jobber Drill Bit

The Sutton Viper D105 is a 1.5mm jobber drill bit made from high speed steel and sold carded as a single bit. Sutton developed the Viper point for the trades person and the home handy person, and it suits machine and hand held drilling in steel, aluminium, brass, wood and plastics. The point geometry is what sets it apart from a standard HSS bit: it self centers on contact, so the bit does not wander, and it cuts with less downward pressure.

What You Need To Complete The Job

For fine pilot work you want a drill that spins fast and a steady hand. When you move on to concrete and brick, swap to an SDS masonry drill, and for cutting metal to length keep an hacksaw in the kit. The full fastening and cutting range lives in General Hand Tools.

Frequently Asked Questions

What is a 1.5mm drill bit used for?

A 1.5mm HSS bit makes small pilot holes, usually before tapping a thread or opening the hole to a larger size. It is also useful for tiny screw fixings and for starting holes in thin sheet metal where a larger bit would catch and distort the surface.

How fast should I run a 1.5mm bit?

Small HSS bits like this one want a fast spindle speed and a light feed. If you push too hard the bit can flex and snap, so let the point do the cutting and back off as soon as the hole breaks through.

Why is the point self centering?

The 118 degree split point bites into the surface instead of skidding, so the bit starts exactly where you put it. That removes the need to centre punch on most jobs and stops the drill walking along the mark.

Will this bit drill stainless steel?

It will drill stainless, but slowly, and you should use a cutting lubricant and a gentle feed. For regular stainless work the coated Viper Plus variant is the better pick, as the PVD tip holds its edge longer.
