Cobalt Drill Bits Set - 1/16in. Dia. to 1/2in. Dia., 21-Pc. Set
I work in a factory where we use high speed drill bits EVERY day. i purchased these due to the fact they were cobalt, not because they were on sale. the price was right, but the product was wrong. i have broken almost ever bit ive tried thus far, so much so i just closed the case and put them on the back shelf. i will be complaining to Northern about this product since i did buy 2 sets. Thought maybe was just a bad set but both sets are junk.

The best drill bits I've ever used
I do a lot of work with mild steel, sometimes very thick mild steel. While I used to use a torch to cut holes and then a step down bit to round them out, I don't need to go through all of that with these bits around. Doing a base hole with an 1/8" bit and then following up with a larger bit is short work with these. Hold their edge a while. Easy to re-sharpen using a Drill Doctor. They are more expensive than titanium bits but well worth it.

Just Drilling Away
I recently purchased a set of (Cobalt) Drill Bits 1/16in. Dia. to 1/2in. Dia., 21-Pc. Set, I have been using them and they are by far the best set of drills I have owned. They handle the tough jobs as well as the finesse jobs, I sometimes abuse drills and these Drill Bits seem to handle whatever I need them to do and the best thing is they stay sharper longer. I have already recommended these Drill Bits to my friends and family.
HAVE A GREAT DAY AND DREAM ABOUT DRILLING,

top of the line
These bits cut through mild steel, stainless, and breezes through aluminum like a hot knife through butter. I've paid twice as much for bits this high in quality. Highly recommended!

Cobalt Bits- Metal Case
I've been using these Bits in the Metal Cases for a long time now in a Shop Situation. I love the Bits. I especially love the cases. Good, Sharp, dependable bits are a must. Anyone who is always reaching for a bit knows what I mean. Having these substantial metal cases with this great assortment make my life easier and my job more enjoyable. Anyone that uses those bits in plastic boxes should try spending a little more and see how great it is to have this heavy solid case always ready to go when needed. The bits themselves are dependable and very rarely do I break a bit. This is an awesome Choice for those serious about having a good case of bits. Seriously, Get some.

Cobalt bits are worth the money
I've used high speed bits for years. They are good for drilling in light metal. They won't stand up under heavy usage. These cobalt bits are for heavier usage. They have stood the test of time on my farm.

Best metal bits I've ever used
I was drilling into 1/4 steel plate.I tried several other brand name bits with no success. I was skeptical of the listed excellent reviews. These are great drill bits ! please add my name to the list of very satisfied customers. I'm buying another set for a friend.

Very good value
I have been purchasing colbalt bits one at a time for use on hardened and stainless steel. When comparing this set to individutal purchases this is a very good buy.
