Product Overview

Coated with a black oxide finish for reduced friction and minimal heat buildup, these heavy-duty drill bits are rated for use on metal to produce clean, burr-free holes. The black oxide drill bits in this 21-piece set from Ryobi have a 135-degree split point so they start penetrating on impact and don’t wander on your workpiece. Also suitable for wood and plastic drilling, these durable bits are constructed with a high-speed steel core to meet the demands of repeated use.

Rated 3.4 out of 5 by 29 reviewers.
Rated 3.0 out of 5.0 by Ryobi Bits Well you get what you pay for. Bought these just for a cheap set to use on occasions and they seem to be sharp and drill fine they just break easy. Would recommend for lite duty use only. November 21, 2015
Rated 4.0 out of 5.0 by Good drill bit set I bought this set to replace one I lost. It seems the bits are made of good quality steel and perform well. I'd recommend these for the DIY'er. July 21, 2015
Rated 5.0 out of 5.0 by Drill bits Great value and high quality for the money would buy this brand again July 21, 2015
Rated 4.0 out of 5.0 by Impulse Purchases Can Be Good The set is working out really well. We have not broken one yet and that is saying a lot! June 9, 2015
Rated 2.0 out of 5.0 by Not sharp- can't handle wood I disagree with previous posters who say that these are good for household use. The price is certainly right and they are fine for drywall or plastic, but as soon as you hit a stud, get ready to sweat. Took me forever to drill just a half inch into the stud to hang a curtain rod and when I pulled the bill out of the wall it felt hot enough to actually ignite the sawdust. Scary. I'm going to see if I can return these. Funny thing is, when I was in the store I was like < "huh, these are $10 cheaper than the Milwaukee set but they look like the exact same thing." Yeah.. not the same thing at all. April 19, 2013
Rated 5.0 out of 5.0 by Used them this weekend. Work as expected Got them on a clearance shelf, like $8. Dreat deal April 28, 2015
Rated 4.0 out of 5.0 by Great product ! Good enexpensive drills bits with compact carrier. February 3, 2015
Rated 1.0 out of 5.0 by Good price, poor quality I broke 4 bits within the first hour of use. It's nice that they provide doubles of common sizes, but these bits break entirely too easy, dull out quickly, and take forever to drill through metal. Spend a little extra and get a quality set.
