Hole Saw - experience - help please.

(1/4) > >>

Richardgregory:
I'm sort of a newbie when it comes to wood working and especially using a hole saw to drill a 3.5 inch hole into 3/4" plywood for a trackball.

I am using a Dewalt 20Volt Brushless drill and set the speed setting to 1 for higher torque instead of higher speed and the setting of the drill to the drill driver setting.

When I went to drill the hole, my experience was that the drill would catch on the wood and with such force that it through my grip off as my wrist went flying. 

What am I doing wrong?  Is it the drill that might not have enough power?  Or something else....

Would appreciate any help for next time...

Thank you

It is a big hole saw for a hand drill. I find that high speed and a light touch helps keep it from binding.

I used a hole saw bit to drill my trackball hole. Whether you use high speed or low speed you need to keep the hole saw drill bit even especially when you start the hole. If you rock/angle the bit it can bind in the hole .... not great for the wrists! Start with a practice piece of wood, keep the bit square with the wood and apply light not heavy downward pressure until you get used to drilling it. The larger holes are more sensitive to binding but after you drill a few you'll get the feel for it :cheers:
