2-1/2 Inch HSS M2 Drill Bit Hole Saw for Metal, Steel, Iron, Alloy, Ideal for Electricians, Plumbers, DIYs, Metal Professionals

I drill holes in metal for a living. This was rather expensive. “You get what you pay for.” Is what I think when it comes to tools. Waste of money. I have had cheaper ones similar to this last years.

I used the 3/4 inch bit/saw to cut 6 holes into my car trailer frame to install new marker lights. The frame on my trailer is 3/8" thick steel. This cut through it like it was aluminum. It didn't dull or slow down through all 6 holes. I did use a bit of wd40 to help keep it lubed a bit as you should. I was very impressed it makes a very clean cut and left few to no metal burrs for me to remove.

Excellent quality; good instruction follow-up from McJ. Very precise holes. Plug eject spring and extra pilot bit are handy time-saving features. Cutting oil essential. Most small drill presses do not have a slow enough speed (230 rpm). Mine was 628 rpm. You can of course drill at higher speed; but, the bit will wear out much, much faster. Google "Intermediate Drill Speed Reduction" if you want to modify your existing drill press for extended metal drilling.

Great product. After reading negative reviews I decided to give the drill a try and I'm glad I did. I had 4 3/4" holes thru 3/8" plate. I used a punch then predrilled with a 1/4" Drill to create a small crater for the bit drill to follow. Drill worked perfectly in my drill press at a medium speed. I also used a liberal amount of tread cutting oil and didn't let the bit get hot. Not sure how this bit will work on a hand held drill, but I think slow speed and using oil is a must when drilling thicker material.

I tried this upon recommendation of a friend. Came nicely packed in a reusable plastic sleeve, and the build quality looks great at first glance. Good heavy feel. I like that the pilot bit can be replaced via hex screw. It cut through 3/16 aluminum plate without a hitch, but I admit that since it looks so pretty I will wait awhile before trying it on steel... I just enjoy keeping tools pristine for awhile. I did try it on plywood, and it made a great precise cut, although thickness is limited to 1/2 inch plywood max. It is likely I will buy an additional bit or two of different sizes, as the need arises.

Tool worked great. I tried to used different tools to cut through metal but this one is the only one that worked.

Great tool! Cuts a clean hole with ease. Very sharp; can get away from you and snap the pilot bit. I've broken (2) pilot bits almost immediately while using a portable drill. The pilot bits are extremely hard but brittle; they will not bend. I've made my own pilot bit from a standard drill bit. Overall, I'm very happy with the product but wish that the pilot bit was a bit softer. I don't see any issues with the pilot bit when the work is held in a vise on a drill press.

I have work with PDR in Brazil for a long time and that tool helps me be the best

The fact that I've managed to punch 6 holes through 1/2" steel is impressive. The drawback that I'm seeing is the limited depth of the bit (<1/2") which requires finishing the hole from the back side.The pilot bit is also sub-par, but if you pre-drill with a good bit, the hole saw will do it's job well.

Worked great. Purchased 2 of these 9/16" and 22mm for one project. Drill 6 22mm holes and 12 9/16" holes in an 8" I beam. I pre-drilled the pilot holes took it easy, used lots of cutting fluid. Drilled using a hand held cordless drill.

Je m'en sers pour percer de l'acier 1/4 de po. Après de multiples usages en utilisant de l'huile de coupe, elle perce encore parfaitement. J'en suis très content.

Bought this to drill 4 holes in 1/4" steel, and worked like a charm. Kept very well lubricated when drilling and looks like still very sharp and will last.

Bought it to drill a hole in my Jeep for installation of a CB radio. This thing is sharp and cut through the body like nothing! Recommend!
