It worked exactly the way I wanted

Throw this in a drill press and it cuts through steel like it’s aluminium. Does well with a cordless drill as well. Doesn’t wander much. So far has lasted way longer than a normal junk carbide or titanium coated bit. For metal drilling I’m going cobalt from now on, the price is worth it.

Great bit. Very sharp. Went thru the wood like butter. Had some issues with the metal plate behind it, but it eventually penetrated it also.

Bought this to drill through a car frame rail and worked flawless. Drilled through the metal with little effort.

Used this to drill through a locked door in my home that didn’t have a key. I used a normal drill bit for 30 minutes to no avail on the anti-drill insert. This drill bit got through in less than a minute.

Great drill. A little proces but it went through 3/16″ mild steel like butter without having to drill a bunch of sequentially larger pilot holes.

bit works great slow speed, we drill 15-20 sheets of steel roofing at a time 20 holes each sheet. lots of drilled feet by the end of the day. not the best bits in the world but will certainly work great if you know how to take care of them during use.

It drilled perftly through the bolts I was trying to get off of my lawnmower. I would recommend trying it for yourself.

I have doors that are made from recycled wood. I tried to drill holes through the door with a cheap-o drill bit I had and it took over 10 minutes to get one hole drilled. I bought this drill bit, and it turned that time into 10 seconds per hole. I wish I had purchased this before making the first hole.

Item in great shape out of the container. Very sharp, definitely straight, and superb craftsmanship. Cut right through steel, wood and almost anything else you might desire. Excellent drill bit.

this drill bit did exactly what I needed it for. I especially liked the guiding nipple at the tip. I have had it for a month now and needed it to drill a large hole into a barbecue in order to insert a thermometer.

Quickly and repeatedly went through the 1/8″ angle iron
Camille Hessel (verified owner) –
Really? You want me to review a drill bit? Umm, it put a hole in the material I wanted so I guess it was at least good.

Good drill bit. Exactly as expected.
