EZARC Carbide Hole Saw Heavy Duty, Hole Cutter for Stainless Steel, Sheet Metal 3/4" 19mm

This is exactly what I needed to bore a 1-1/4" hole in a stainless steel sink deck that was over 1/8" thick. The size needed for a reverse osmosis filter/dispenser system. Well worth the cost. Make sure to use cutting fluid or oil while drilling to keep this bit from overheating. Makes a perfect clean cut

Haven't used it a lot yet, but I'm impressed so far. It's well made, accurate, sharp and has a nice finish. The only thing that may be suspect is how long the ejector spring will last. Time will tell.

We bought this tool so we could put a Reverse Osmosis system in our kitchen. It worked great. We used gun oil as the lubricant to help the drill not overheat. It took less than 60 seconds to get the hole. If you are needing to do something similar as myself, buy this tool.

This cutter worked well on 3/16" galvanized steel until the pilot bit, which was cheap and fragile, snapped. Tried to contact the manufacturer using the information on the package. No response. Terrible customer service! And while a replacement was listed on Amazon, it did not come with the spring (likely to disappear when the bit breaks) and was out of stock. Fortunately, I found a replacement from another company. If you're in the same predicament, search for "Ideal Industries SmoothStart Replacement Pilot Drill". It fits, comes with a spring, and appears to be made of better metal than the one that came with the hole cutter.

This bit cut clean holes through thin sheet metal. I think I would use thus up to maybe 1/8 mild steel with appropriate lubrication and cooling fluid.

Fast , clean, long lasting

Holes for camera installs

Went on a job site that required me to cut into a 1/4" thick beam to access my conduit, (Only Reason Why I Purchased These) and it did not even cut a full ring. It had no cutting power whatsoever. I literally could not believe what I was seeing. I went into my tool box and pulled out an older Diablo Hole Saw and cut through the same beam without any issues.The sad part is I purchased these 3 months ago and this is the first time I needed them and there is no chance for a refund.Looks like they are tool box decoration,I do not recommend these for anything metal or stainless steel, Heck I would be Leary of wood as well.

prodotto come da descrizione,fa il suo lavoro molto bene

La Corona Perforadora EZARC Sierra de Corona Broca Circular de Carburo es una herramienta de perforación de alta calidad diseñada para perforar agujeros precisos y limpios en metal y acero inoxidable. Esta corona está fabricada con materiales de grado industrial, lo que la hace resistente y duradera, capaz de soportar el desgaste que se produce en la perforación de materiales duros y difíciles de cortar.La corona tiene un diámetro de 32 mm y utiliza carburo de tungsteno como material de corte, lo que le da una gran capacidad para cortar y una vida útil más larga que otras coronas convencionales. Además, su diseño de dientes dentados asegura un corte suave y eficiente, sin engancharse ni vibrar, lo que resulta en un trabajo más rápido y sin esfuerzo.En cuanto a la calidad de corte, la Corona Perforadora EZARC Sierra de Corona Broca Circular de Carburo es impresionante. Esta herramienta es capaz de perforar agujeros limpios y precisos en acero inoxidable y otros materiales metálicos sin desgarrar o romper la superficie del material. También es eficaz para perforar plásticos, madera y otros materiales no metálicos.En cuanto a la duración de la herramienta, la Corona Perforadora EZARC Sierra de Corona Broca Circular de Carburo tiene una vida útil más larga que otras coronas perforadoras. Esto se debe a la calidad del carburo de tungsteno utilizado en la herramienta, que le permite mantener su filo por más tiempo que otros materiales de corte.Sin embargo, un problema que se puede encontrar al utilizar esta herramienta es que, debido a su diseño de dientes dentados, la corona produce una especie de rebaba en el material perforado. Esta rebaba puede limitar la profundidad de la perforación, ya que se acumula en la base del agujero, lo que impide que la herramienta continúe perforando a una profundidad mayor.En resumen, la Corona Perforadora EZARC Sierra de Corona Broca Circular de Carburo es una herramienta de alta calidad y eficiente para la perforación de metales y otros materiales. Su diseño de dientes dentados y el uso de carburo de tungsteno la hacen duradera y capaz de cortar materiales duros con facilidad. Sin embargo, la rebaba que produce puede limitar la profundidad de la perforación, lo que puede ser un inconveniente en algunas situaciones.Para solucionar este problema, se recomienda usar una lima para eliminar la rebaba en la base del agujero después de la perforación, lo que permitirá continuar perforando a una mayor profundidad. Además, también se puede usar la herramienta en combinación con un lubricante de corte, lo que reducirá la fricción y la acumulación de rebaba.En general, la Corona Perforadora EZARC Sierra de Corona Broca Circular de Carburo es una herramienta altamente recomendable para aquellos que necesitan perforar metales y otros materiales duros con regularidad. Su capacidad para cortar de manera precisa y su vida útil más larga que otras coronas perforadoras hacen que valga la pena el costo adicional. Si se tiene en cuenta el problema de la rebaba y se toman medidas para solucionarlo, esta herramienta puede ser una excelente inversión para cualquier persona que necesite perforar agujeros de manera eficiente y precisa.

Cuts through thin steel efficiently.

pour faire des trous dans de l'aluminium de 3 mm d'épaisseur,résultat parfais .Avec d'autres marques (que je posséde aussi)au bout de 5 trou j'avais déja cassé un carbure ,la avec ERZARC(marque que je ne connaissé pas)aucun carbure n'a cassé au bout de 24 trous,je crois que s'est parce les carbures sont un peut plus fin il attaque moins de métal et il sont aussi plus solide.Résultat un travail parfait et prés pour un autre travail.je recommande vivement cette marque.

Oh, WHY didn't I find these long before now!I install cooling systems, and I work on many sites where I need to cut holes in metal - sometimes thick and sodding hard metal. Shipping Containers are a prime example.I've spent many 100s of pounds in 10 years on those standard hole cutters - the Bosch ones being the best I could find, but would still only last a couple of cuts then start giving up, and often new cutters would dull before completing the cut. On many occasions, I was having to reach for a drill to drill many small holes for the hole cutter to take, an angle grinder to finish the job or to cut a rough squarish holeAnd then I happened across this "Tungsten Carbide Teeth Hole Saw" - never seen one in action or on-site so was sceptical it would be effective. I was also wary that it looked like something that was best suited on a bench drill, whereas I will be using on a cordless drill on-site. It is not cheap, but I was desperate so took a puntAnd then I used it... WOW! A quick, clean hole - like a very sharp knife through melted butter! What have I been missing for all these years! I'm not talking silly thin metal - this is the same for thick stainless steel - and it has yet to blunt the jaws. It's not even worth trying to compare to the other standard hole saws - this is in a league of its own.It was one of those times of enlightenment - the first time I used this I was full of bad memories of years gone past with a spinning hole cutter doing nothing other than making a nice circle and no hole... many broken bits where you try and twist the cutter to "take"... thousands of small holes and cutting between using a chisel. I almost cried, folks...Now been used on many occasions far outlasting any other hole saw I ever had the displeasure of using, so despite the high cost this is both a money saver and a time saver.The only niggle is that the hole cutters have a depth stop which can be a pain when I'm drilling in panels with a cavity. I suspect this is because it is (as noted) purposed for a bench drill and not for the purpose I am using it for. No worries as I can alternate between a slightly larger hole cutter then a smaller hole to reach the second stageA word of warning - this produces swarf and a lot of it. Wear glove and a protecting face mask or you will regret it! I would also recommend a cutting spray, as that also helps it slide through the metal, although I have found it not to be essential, but like to look after the bitIf anyone regularly cuts through metal, then I would strongly suggest you dip in your pockets and buy this cutter
