Good quality bits and reasonable price. A little disappointed they weren’t individually packaged. More important with larger bits I guess.

Excellent quality, very sharp and stayed sharp. A couple bits in my 100 piece set are getting dull so I replaced them. Unfortunately Spruce doesnt offer all sizes, they skip some numbers, and larger sizes as well. Sure wish they had a complete selection. Its tough to find single bits from other sources with as reasonable shipping as A/C Spruce.

I am learning to scratch build an airplane. This was a big help learning that process. It takes materials and I have some now :D Excellent condition and they allowed me to come and pick up the stuff myself. Awesome! Great customer service. I had a lot of questions and they did not get upset with me when I changed my mind and decided to go in another direction. They simply supported me and I purchased even more stuff! I have been using this company for decades. I first started with the supplies needed for R/C aircraft back in the 80 and 90s.

These are very sharp, great drill bits. I wish the size stampings were a little better (some are readable, some are not), but the actual drill bit cutting quality is amazing.

Cobalt is great for repeated drilling of fiberglass. Lasts longer than other bits.

As always the quality of the product is excellent but I ordered two drills of the same size and neither was the right one. However one was mismarked by the manufacturer. The size difference was obvious to the eye. This was the first time in over 25 years that this has happened and the service you get from Aircraft Spruce is great.

The metal sheets are fine. The drills are fine. And the rivets are fine. All good, thank you.

Used 1 (..and ordered 10) on a PA-12 wing to remove rivets, and its still going.
VERY SATISFIED!

These are very high quality drill bits at a great price. I am a machinist and buy bits from a lot of different sources, but much prefer these in the sizes Spruce has available.

I ordered two #30 Bits in case one went dull. I had to drill out 96 rivets in a Cessna. No problem and I never needed the second bit. I center punched each rivet and the bit never wandered and it grabbed perfectly.

Great drills at a great price (which is good because you go through a zillion of them while building!).

These bits work very well in steel and aluminum. Would be nice if there was a 10 or 12 pack available with a discount.

These cobalt drill bits are reasonably priced compared to offerings in the local hardware stores and Fastenal. I have not used them enough to know if they last longer.

Love the drill bits. They are the best on the market. Just wish whoever packaged them could count. I ordered and paid for 10, but got 9. How can I prove that?

For standard drilling tasks these are fine, but I went through five of them driving out a line of aluminum pop rivets.

Advertised as long lasting. That may or may not be true. They aren’t nearly as sharpe as HSS. They are far more prone to wander than cheaper HSS. Probably fine in a drill press but not a good choice for drilling aluminum, especially rivet removal.

I love the quick service however, using the drill gage purchased in the order the #41 drill bits were actually #40.

The #40 and #30 bits are not split point. And I received #30 bits that had a negative rake angle meaning that it just sat on the surface and would not 'bite' into and feed into the material
