Draper HSS 15 Piece Titanium Nitride Coated Drill Set | 1.5 to 10mm Masonry Kit |10/13mm Chuck | 135° Split Point | Multifunctional Drill Bits | Foldable Storage Case | 18549

All my drill bits are out in the shed so I thought I'd get a set for indoor use. I've used a couple of them so far and they do the job I need them to do. I find Draper a very reliable brand for a DIYer like myself. The price of £7.92 was pretty good too.

I bought these to drill out a broken stainless steel (M6) bolt. It took a long time (> hour) requiring a relatively slow speed drill so not to overheat and blunt the bit and also not to heat harden the stainless steel. A drop of oil now and then helped. Going hell for leather with a high speed drill would have been a recipe for disaster.I broke one due to my impatience and the awkward location. Luckily I could pull it out. Drilled several 2 mm holes thru ~20 mm stainless without destroying the face or cutting edge of bit, the coating is still intact and doing its job. They seem just as sharp when job was completed as at the beginning. Would gobble up mild steel if treated correctly.Bits are clearly marked, stamped sizes, which is much more than other bits i have. Case is handy and stores the bits securely.

Drill bits seem OK however the little plastic clips that hold them in have broken, 3 of them anyway. Just means they roll about in the box because they can't be held in place.

Value for money quality drills in a robust case. Used domestically.

Used the drill set for the 1st time today to drill some 3.2mm holes to act as a pilot for a 4mm tap.Unfortunately the 3.2 was extremely brittle and snapped straight away. I've tapped many holes before and was very surprised by the outcome. Had to settle for a 3.5mm from the same set that performed fine.Would advise caution when using the smaller sizes.

I've been using these every few days for well over a year now, it has all the sizes I need except for fine work. The drills are still sharp (I just never cut metal with them). The case is nice and sturdy and still works. It also looks cool and stands out a bit from my other tools so I can find it easily.

I had some nasty tiles to drill and so I destroyed 1 drill bit quite quickly but the secret is keep a cup of water close by and periodically cool your bit down in it and will last a lot longer.
