TCT Hole Saw Set, 2-Pack of 3/4" (19mm) Heavy Duty Tungsten Carbide Tipped Hole Cutters for Stainless Steel Mild Steel Copper Iron Brass Plastic and More, with Titanium-Plated Pilot Drill Bits

Only used it once so far since I just had to drill one hole. But it worked better than I expected. Went through 1/8" thick mild steel like butter and made a nice clean hole with no burrs or cleanup necessary. Even if I never need it again, it was definitely worth the price.

Great hole saw for metal. Precise. Carbide cutters make fast work of drilling. The hole diameter was spot-on. This is a steel fill/inspection bung on a Ford 9” axle housing, about to he Tig welded in place.

These bits worked very well. Took my time cut through 3/8 hard steel very well. Very happy with outcome.

Bought the 3/4” ones, drilled about 12 holes into 1/4” aluminum before the pilot bit broke. The second bit I drilled into 12 gauge stainless. 5 holes and cut through with ease. Overall I’d buy more if needed for other projects.

Product worked amazing was super impressed! Bang for the buck for sure look forward to using the other sizes I bought. Thank you.

I bought two sizes of these, the first the drill bit broke within about 30 seconds of use. I swapped the drill bits and the larger bit cut about 1/2 of the hole I was attempting before going dull and just spinning. Terrible quality and nothing but a waste of money. I'd return them but I bought them while traveling and the return period has passed.

Needed a 3" hole saw for a metal box and this one cut thru it like butter. Made well and very sharp.
