I have a 4 inch hole saw looks like this:

I have it attached to my hand drill and want to cut my exhause holes......i tried it on a piece of test wood...which is thinner than the side of the box i need to get through.....and it just locked up...jerked me around a bit but would not cut through...the saw is 4 amps.

Whats the problem here getting pretty frustrated.

Get the first hole started, as in let the teeth gently cut into it a little bit. Then you have something its in, not bouncing around on. Then just slowly apply more speed until its cutting away...........

didnt work..tried 5 times in the test piece of wood, just gets jammed after creating a little bit of a circle.

higher speed on the drill and dont press down so hard. let the teeth do the work.

and the teeth on the bit are sharp?

I'm not sure, but I think you're using a hole saw designed for metal, instead of wood.

sike89 · Apr 20, 2012

with cutting holes, as its been mentioned above, you need to go slow and let the teeth do the work. Specially with a larger hole.

Is the drill turning the right way? (clockwise)

dxfan227 · Apr 20, 2012

went slow, went fast, pushed in hard, did it lightly....drill is 4 amps...is this not powerful enough maybe....ughghg

dxfan227 · Apr 20, 2012

I really dont have anymore ideas on what to do here..

Grampa · Apr 20, 2012

keep the teeth square with the surface and go slowly. it really shouldnt be difficult at all especially with a 4amp drill. also make sure your drill isnt going in reverse or something. ive seen it happen a few times in my day.

well first off your drill can't be 4 amp because it is a drill not a speaker...so it might be 4 volts...anyway...and really there is already a post with my idea...is it possible that you are using a bit for metal on wood? There are different ones, and it is weird because the ones for wood will cut metal, but the ones for metal can't cut wood...I would think metal would be stronger...my husband has an 18 volt drill and it doesn't seem overly powerful so perhaps you do need a stronger drill if it is a terribly thick piece of wood.

Do you have the pilot bit in the hole saw?...there should be a 1/4" drill bit in the mandrel also.

everything that runs electricity has amps. volts and amps not just speakers. your husband's 18v drill has a no load current of about 2.6 amps

only cordless drills are rated in volts (the voltage of the battery)

A mans drill has cord, and is rated in amps..lol jk

"...ideal for metal and wood cutting in a wide variety of HVAC, electrical, plumbing and maintenance/repair applications..."

Nope, its good for wood. :-)

Hey, I prefer corded drills as well since I know what a pain it could be to drill with an underpowered drill. Having an electrical background gave me many opportunities to fuck around with hole saws. What u need is a drill with enough torque that could literally tear ur elbow apart if it locks up on u and a pilot bit of course. Start with the hole saw perpendicular to the wood as mentioned. Once the teeth start to bite slowly start to rotate the drill a little in the clockwise direction around and around and u will find it much easier. This is just to get it started, then u can rock the drill slightly up and down as it's starts to go through the wood. This always works for me and is very easy to do. One other thing is make sure u hold the drill with both hands.

SUCCESS. here are some tips that helped

drill the pilot hole first

go SLOW..let the teeth do the work ( find the sweet spot between jammed and not cutting

wobble the blade.

and the best tip was by far to run the bit in reverse , while this does take longer it also causes no "bite" or "grab"

oh and i burnt out the drill basically ( sparks and smoke ) but were though pictures later

lol im glad you got it cut but god damn! sparks and smoke??
