Drilling for attaching PF pipe connector

I used it as a hole to attach the PF pipe connector to the steel plate. I drilled several holes in an iron plate about 1.5 mm thick, but I was able to do the work quite easily. I think that the sharpness is particularly problematic.

Rather than drilling suddenly with a thick drill, leave a small hole and step by step with this product
The finished one is finished clean.

Heavy feeling, sturdy! It was worthwhile to dare to buy.
It seems to last for a long time if you do not burn the blade with high speed rotation.
