Draper HSS Long Metric Drill Bit 3.5 x 100mm (10 Pack) is rated 3.1 out of 5 by 7.
Rated 4 out of 5 by from Helpful for piloting for long screws You need 70mm+ of drill beyond the chuck to pilot for decent sized m6 screws for screwing into structural timber etc unless you want to pay the price for self cutting screws (which in my opinion need a little help and countersinking at least). I go through half a pack these easily on a build. I use them with a countersinking collar. Why are they so poor quality though? I mean you can break them just hitting a knot, whereas the standard-sized cheap ones are much better quality. Supplier should make a little effort to improve these.

Rated 5 out of 5 by from The extra length always helps! I needed a long drill to make pilot holes through thick pieces of oak - these drills performed excellently.
