I was hesitant to buy a brand I wasn't familiar with, but this is one great drill. Went through the stainless I bought it for like butter. I can't testify to its long range durability as I probably won't use it much, but it did the job it was intended for very well.

My drill press has a 3/8 Chuck. Wow $43.81 for this hard to find drill bit really blew the cost of my project! I felt the cost was outrageous!

The Drill America 5/8 High Speed Steel Black Gold KFD Drill Bit could not enlarge an existing 1/2 inch hole in a 1/4 inch thick piece of corten steel and the point was destroyed in trying. This D/ACO Series Cobalt Drill Bit (at twice the price) did the job.

Cuts through stainless and hardened steels where titanium and others fail. Use some oil to preserve its edge for longer life.

Drilled 15 holes through 1 in plate steel just fine. I used tap magic and a drill press.

Bought a cheaper bit 1st - it failed immediately so I ordered this bit from Drill America. This bit drilled the 16 holes I needed and was still going strong at the end. Drill America bits stand up to the test.

    Ok, maybe not the noggin! But for drilling steel this bit worked as a cobalt bit should. No issues, and it cut fast. Drilled through 1/4 plate steel pretty quickly using a 20 volt cordless drill. Quality seems good and was cheaper than big brand names. Like the reduced shank so i could use in 1/2 drill. Nothing worse then having a bunch of drill bits with the size worn off from slippage, so pick up a couple.

    The bit fit my 10 amp Drill and it met expectations best drill bit I have ever used on steel.

    Can't beat the quality for the price... I used the bit to drill a motorcycle rotor and it worked great with low speed and lots of oil

    Had a project to drill 4x 5/8 holes in hardened steel. I had ordered 3 Cobalt hss bits from two different brands. Each failed drilling only about an 1/8 of the material. Ordered the bit from Drill America and finished the first hole in 20sec or less and went on to do the other three holes without issue using the single bit.

    Lasted about 2 hours of use against hardened steel before starting to dull.Would last a lot longer against mild steel and even longer with soft metals.

    It just works. I used it on stainless steel and while it worked good, it was on the slower side of drilling.
