getting a new bench drill (dunno what its called) and thinking to buy Nova 16RF 375w drill. is the 375 wat enough to drill max 22mm holes to steel and aluminium?

if the chuck can fit a 22mm bit it will drill, just take it slow and use cutting cutting fluid

edit: looked it up it has a 16mm chuck so you will need to get a steped drill bit(idk its right name) or spade bits(only alu)

that was just what i wanted to hear. thanks!

That stepped drill is really intended for enlarging holes in sheet metal. You can buy larger diameter drills with a reduced shank size (13 or 16mm).


The second one down has a reduced shank Look for these.

The reduced shank ones are most common in sizes above 13 or 16mm. Most large diameter drills you purchase individually or in a set from a hardware store will have reduced shanks.

You can plausibly drill 22mm holes with a 375W drill, but don't expect it to be quick. Take it slow and use a lot of lube.

progressively drill larger holes. start with maybe 8mm, then 12mm, etc up to your desired size. It is amazing how well that works. I was having some trouble with 4140 the other day, and this accelerated the process by a factor of 5.

cutting fluid is always a good idea. WD-40 or kerosene is fine for aluminum. Tap-matic gold is amazing for steel and smells pretty good.

...yes it does.

But back on topic.... i used to work in a metal shop, we always drilled smaller holes first.. and enlarged them later.

This also makes the hole much easier to line up where you want them.

There was no useful information in this post so I put this here.....
