DRILLFORCE HSS Jobber Length 10 PCS,5/32" x 3-1/8"Titanium Coated Twist Drill Bits, Metal Drill, Ideal for Drilling on mild Steel, Copper, Aluminum, Zinc Alloy etc. Pack in Plastic Bag (5/32)

I bought these figuring they would be "cheap" and not very good because they came in a pack of 10. I drilled almost 150 holes in 3/16" steel for a trailer floor and used 1 bit. I now have a lifetime supply of this size.

broke easy only drilled 40 holes with 10 bits

Would recommend these bits . They were sharp and a bargain at the purchased price !

These are excellent drill bits for drilling I-beams on trailers

I could not figure these bits out. I have a 25-foot equipment trailer I was reflooring and used these bits to drill the holes for floor fasteners. The first bit lasted much longer than any ordinary bit would last. The 3 of us working on this trailer, were talking about how phenomenal these bits were. Then.....Some of the bits would not drill one hole before burning up, others snapped in two half way through the hole. Out of the 10 bits, each bit was as different as the kids on The Brady Bunch! If all 10 bits had been like the first bit I used, I could have used 3 bits on almost 200 holes. Instead, I ran out of bits before I finished. If this company had quality control to make each bit like the first bit I used, I'd buy boxes of every size bit they make and pass on my leftover bits to my grandkids!

These drill bits even drilled through the screws left from the prior deck and didn’t snap or break. These are really good quality nothing like Home Depo bits.

This is an essential size drill bit for proper setting on #10 Riv-Nuts. This is a less common size doesn't come in most drill bit sets so I buy these sets of ten since I set a lot of riv-nuts.

They fill the spot missing in the set of drills that I bought.
