ASNOMY Tungsten Carbide Tipped Hole Saw Drill Bit for Hard Metal, 1 Inch T.C.T Hole Saw Cutter with 2pcs Titanium-Plated Pilot Drill bit for Metal, Steel, Iron, Wood, Plastic

Had to cut a JBL marine radio into a dash on a classic car. Worked beautifully, cut even and quick.

Cuts extremely well and leaves a smooth hole. Works best in a drill press as you must maintain firm pressure to reduce chattering

I have to create holes in Fiber or Glass Reinforced Plastic (GRP & FRP) boxes. If the holes are much bigger than 1/4in then the plastic tends to shatter around the hole or the box cracks. I tried using a hole saw for wood but it gets blunt quickly and always leaves a rough portion at one point where is breaks through, not to mention the mess of dust that gets into your hands and you have to wear a mask. A friend introduced these to me. They are almost perfect for cutting holes into FRP, there is very little dust and it is fine, the hole is clean cut and the whole circle comes out near perfect. I will always use these for making holes in FRP and GRP boxes. Would recommend and I love them.

I used this hole saw in a hand drill to put vent holes in a 50-gallon drum burn barrel. The hole saw, center drill bits (2), springs, and allen wrench come in a nice plastic container. When installing the center drill bits, there is a "flat" side that needs to be aligned with the allen set screw. If these are not aligned, the center drill bit will come loose (don't ask me how I know that). I drilled about 13 holes in the barrel which is made sheet metal probably about 1 mm thick. The center drill bit cut through the metal ok -- nothing spectacular but not bad. The hole saw portion worked fine, but unless the saw was entering the metal at a perfect 90-degree angle, like it would when using a drill press, one of the hole saw teeth would catch as it cut completely through the metal and torque the hand drill almost out of my hand. After several holes I was better at keeping the hole saw at the correct angle and mostly avoid this. I ran the drill at a slow speed and used cutting oil, two important tips whenever cutting metal. I noticed a slight slow down (i.e., dulling) on the center drill bit from the first two the last hole, but expect it will continue cut fine for many more holes. The item comes with two center drill bits. The hole saw did not seem to dull over the course of the 13 holes I drilled. I would buy this again for the price and the limited number of times I expect to use it.

Worked great for drill holes for new locks in Stainless Steel doors, first one lost a tooth, seller replaced, in just 1 day, delivered next day, no others were showing any damage, went through 35 holes, like all steel, use lots of oil and keep cool with water bucket or oil dip bucket , I prefer oil dip.

Loaded a 60mm version onto my drill press. Excellent cut, nice clean hole, almost looks as if it came off a mill or CNC.I needed to make some precise holes and this hole saw did not disappoint. Make sure you go slow. I'm able to run my drill press at its lowest speed 200RPM which is what you want when going through some steel. Then made sure that I was 99.9% square and perpendicular to the work piece. Almost all teeth making contact onto the face of the work piece at the same time. Then as I spun her up, made sure to be generous with the the lube/cutting oil.All I can say is out of all the hole saws, drill bits, spade bits, etc. that I've ever used on a variety of materials. This has come to be the cleanest cut.Had some questions and they responded quickly to address my inquiry.

Bought this to use for some small cut-in can lights being installed in 26 gauge R-panel. Drilled over 20 holes and didn't even chip one tooth off of the saw. Pre-drilled my pilot holes to keep the saw from catching and it did a great job.

Used this to drill (4) holes in 1/4" mild steel. It lasted 3.5 holes. Cut great up until that point. For the price, i wasn't all that surprised.

sharp and cuts good, cut 10 holes in steel don't know how long it will last though, pricey name brand not as good as this thing.

La precisión para perfóralar

I needed to cut some AR400 plate steel. these cutters, while not the best quality, did the job. I was able to cut 4 holes at 2" diameter in 3/4" thick steel. Chip evacuation is rather poor, so i had to retract the cutter often to clear chips. And i used plenty of cutting oil to give the cutter a fighting chance. After these four holes, the teeth on the cutter are very worn, and i don't think it will cut one more hole.

agujere en una placa de acero y funciono muy bien, hice lo mismo en una lamina y se quebró la broca pero trae una de repuesto

Buena calidad
