Sutton Viper D105 6.5mm HSS Jobber Drill Bit

The Sutton Viper D105 is a 6.5mm high speed steel jobber drill bit, made to DIN338 dimensions and sold carded as a single bit. The 6.5mm size is a common pilot and clearance choice for metric fixings, often used before opening a hole to its final diameter. The Viper point is a 118 degree split point that self centers on the mark, so the bit starts clean and holds the line, and it drills up to 2 times faster than a conventional HSS bit with less pressure.

What You Need To Complete The Job

A 6.5mm bit needs a drill with a bit of torque, so an 18V cordless or a corded drill is the right match. For masonry, switch to an SDS masonry drill, and keep leather rigger gloves on when handling cut metal. The rest of your cutting kit is under General Hand Tools.

Frequently Asked Questions

What is a 6.5mm drill bit used for?

A 6.5mm HSS bit is a pilot and clearance size used between the standard 6mm and 7mm steps. It suits M7 fixings, self tappers in the 6 to 7mm range, and opening out holes that started at a smaller diameter.

Will this bit suit a pillar drill?

Yes. The 6.5mm DIN338 shank fits a standard 13mm chuck, and the Viper point works well at the speeds a pillar drill holds. It is a good size for repeat holes in a jig or fabrication run.

How do I keep the hole clean in aluminium?

Run a fast speed with a light feed and use a drop of oil. Aluminium can load up on the cutting edges, so lift the bit out and clear the flutes regularly to keep the hole smooth.

Can this bit be used in a drill press at high speed?

Yes, within reason. Set a sensible speed for a 6.5mm bit in the material you are cutting, and do not run it so fast that the edge overheats. A light, steady feed gives the cleanest hole.
