Mollom Heavy Duty Carbide Hole Saw, Hole Cutter cuts Stainless Steel, mild Steel, Iron, Copper, Brass, Plastic (3 76mm)

As the title states, the feeder bit broke on the very 1st hole. It was only a typical metal stud and nothing thick at all. It broke immediately as it penetrated. Im a plumber and tend to use a hole saw for my holes but after trying out a similar kit to what this bit is, figured it would work great. It didnt work at all. Returning for refund and I will not bother to try again. Time is money and this feeder bit (also called the guide bit) is far to cheap to work as such a bit would require.

They work great.

I do a lot of truck frame modifications, these bits save a lot of time.

Smooth cit in 1/4 steel four holes and works great

Came in short wait time was excellent for cutting 16guage metal cut clean was very useful thank you

Use a god oil to lube hole cutter when using it.

Product arrived on time and worked very well to drill holes in the fiberglass boat so we could install new electrical outlets. I would recommend.

For the price I thought this was a throw away but it was quite nice. Have not subjected it to repeated use but surprisingly good.

Le facilita hacer el trabajo

Got the job done
