Left Hand Drill Bit Set, 15 Piece | M2 HSS with Titanium Nitride Coating | SAE (1/16" - 1/2")

3 stars because of the low price, 1 star if they were expensive. Most of the drills in this set work just fine. However 3 of the larger size drills do not cut aluminum, let alone steel, at all. Upon further inspection I found that they were not ground properly from the factory. They had been ground with almost no relief angle so that the cutting edge was not contacting the metal at all. If you know what you are doing, you can fix this issue within seconds on the bench grinder. I will say that once you sharpen drills on a bench grinder they are never quite the same because you ruin the perfect geometry from the factory, but in this case, a few seconds on a bench grinder would be a major improvement.

Lost my keyring and had no spare for my storage lock. The storage folks suggested a locksmith could drill out the lock. i ordered the left twist bits and had the lock out in less than sixty seconds.

I rarely write reviews but for this product it was a must. The bits are quality and left handed as promised. I really only use them to extract broken bolts, screws, to allow the opposing grab to try and "unscrew" a sheered bolt. See the photo attached.Anyway, when I placed my order, there was a minor snafu that the seller promptly responded to. The incident was no ones fault, more like an odd circumstance in shipping. The seller was very accommodating, helpful and very respectful in helping to resolve the hiccup. Thanks again!5 stars for sure.

Bought these after a nightmare removing a broken starter bolt from an industrial forklift (aka towmotor). Got to use them this week (same sort of job) and I was happy with them. Cut well and didn't leave me feeling like I was on the verge of breaking a drill bit in a place that would make me want to commit harikari.If they let me down in some sort of fantastical way, I'll update

Absolute garbage. Will not cut steel at all. Bought to drill out a bolt broken well below the surface. In preperation I made a pilot hole with a normal drill bit and filled the hole with CRC cutting fluid- great stuff btw. Chucked up the 3/8 left hand bit and put the drill in reverse. Going slowly and with lots of pressure on the drill it was barely making chips.

very good qaulity

Great Seller!!! Fast shipping!!!!
