Works on bowling ball!
Popeye✓ Verified Purchase•January 9, 2018
Good large drill bits. Worked great for purpose I purchased them for. I used to drill bowling ball. If you purchase for this purpose use fairly slow speed. Do not drill a pilot hole I will repeat this do not use pilot hole. If you do they are very aggressive and will tear up ball. Drill press would help, but not necessary. Then clean up with Dremel type tool and sanding wheel, to bevel hole. Saved over cost of pro shop $40 for holes. Now I can drill balls for whole family. LOL
Worked great on 1/4" steel

These worked great for drilling through 1/4 hot rolled plate steel. I stepped up bit sizes as usual and ensured that the bit was centered and had no problems with the bits handling the material. On first use I made the mistake of having the chuck too close to the piece and had to move the platform, the small deviation in concentricity caused issues, but the bits still managed the hole, though with some frustration. When I corrected this on the next holes, the bits had no problems drilling up to 13/16". Just go slow and use a lubricant
Very pleased

These are great bits for the price. I needed to drill six 7/8 holes through doubled 1/4 inch plate with a hand drill and these did the job with no problem. I don't think I could get another six out of them but this set cost less than one bit of any of these sizes. If they are used in a drill press they would last a very long time.
Great for wood so far

I only bought these to drill through wood, so they're plenty good for that. I haven't tried metal with them. Wooden box they come in is very handy, and the holders inside are just foam. Bits came coated in oil and each in a plastic sheath. Extremely happy with them for light-duty, but not sure how hardened the steel is for drilling through metal yet
Enlarged a hole in cast steel just fine.

Not the prettiest tools straight out of the box (which is surprisingly nice.) The edge that was on them was really rough. However, I used these to cut through a steering knuckle on my jeep project (which is a cast steel), and by working up through the sizes, going slow, and using oil, I managed to enlarge the inch-deep hole to the largest 1 inch diameter without any drama. These are supposedly HSS (and appear to be), so they should hold up fine on steel with careful use and occasional sharpening. These are not 'cobalt' bits or anything of that nature, so you can't abuse these and expect them to hold up for any length of time.
