Hordion200mm/7.87" Hole Saw Bi-Metal Saw Drilling Tool with Twist Drill Bit & L Hex Wrench for Cornhole Boards Wood Plasterboard Plywood Plastic

I attempted to drill a hole in 4 inch schedule 40 PVC pipe. In the process the drill bit snapped at the shoulder. Not a big deal as there were spare bits included, and it worked properly with the second bit.

Good quality. Excellent price.

One thing to note is mine came used. I did not expect that. I’ve never used a large hole saw. Start very slow. Much slower than you expect. But it worked great and did what I needed. Came with all needed parts to attach to a hammer drill.

Got the job done, but worn out after one use!

great price

Cuts nice even hole

Works as expected. Comes with extra drill bits for the center. Only annoying thing was that the center kept wanting to unscrew from the hole saw when the drill would stop as there’s no set screw or anything but tight threads to keep it in place. Probably won’t use it much after the one project I used it for, but it cut nice round holes in drywall.

Works very well for materials stated, comes with 2 extra drill bits as well. Works amazingly and is super quick to put together and into the drill, have a pair of players handy, you can get it started screwing in at first while attaching the bit to the blade but after a couple turns you can't turn it by hand anymore, used plyers holding the bit end and just twisted the circular saw part and it went on very easily and stayed nice and tight. Drills through plastics very easily you almost have to slow yourself down. For the price this is a great product and is very sharp out of the box, paint stays on well also.

Me decepcionó la broca. Ya tuve de éste tipo, pero de otras marcas y la verdad es que me fue muy distinto. La broca no es estable, tiende a saltar, tiende a moverse en momentos de presión y eso vuelve la cosa incómoda. Además, el desempeño es muy bajo, se tarda bastante a diferencia de otras brocas de éste tipo. Acabé rayando la superficie que trabajé (era una prueba, ya sé que no usaré esa broca a menos de ser una superficie que no requiere un buen acabado). Aconsejo mejor una broca Utoolmart de 100mm que pueden encontrar en Amazon México (y quizás USA)

Price is a little high for the quality. I have not used it yet but I suppose it’ll work fairly well people say you must fasten it somehow because it spins loose from the bit and can become dangerous. I will just spot target with my welder

El producto cumple con su función pero como en comentarios anteriores (en ingles) tiene un problema de seguridad ya que si la broca en rotación se detiene súbitamente, el tambor (Sierra) puede desprenderse por la inercia y salirse del sujetador (Peligro!). No tuve problemas al usarlo ya que mi taladro no se detiene súbitamente pero si el suyo lo hace no es recomendable su uso. Espero sirva el comentario para que tomen precauciones...El producto funciono bien para el propósito que lo compre, salvo este punto de seguridad.

Je m'en suis servi pour percer dans une tuile de carton et les dent de coupe sont grosse, a part cela ok.

It Works fine!
