3" hole

[ScottM]

I might have a project that calls for a pair of 3" holes being drilled. I said might as this is a small custom piece and I have not yet committed to doing it. The stock being drilled will be 3/4" hardwood. I would hate to buy a hole saw or forstner bit for one time use. Anyone in my area or the triangle have one I can borrow if I need it?

I have one, if you can't find any closer

Have you thought about using a router with a circle cutting jig? I have used this method for larger holes, but it may be fine for a 3 inch hole.

+1 Scott. I have used this method for cutting 2 1/2" circles (zero clearance inserts for drillpress) on a quite a few occasions.

Router will work, but if you go with a hole saw I have to recommend a carbide tooth saw. For Christmas presents this year I needed to bore 24 - 4" holes in 3/4" oak. Instead of dulling a $40 spiral bit, I thought I'd try the 4" bi-metal hole saw I used on my Paulk bench. Lasted 2 holes and the second hole was a show, with lots of smoke!

Off to Lowe's where I found a $30 carbide tipped hole saw. The thing cut all 24 holes (had to redo the first piece...dovetail slots too) and could easily cut 24 more.

Save your money, buy the best!

I have a 3" Forstner (and a 4") and an adjustable hole cutter that will work. The Forstner has a hex shank so won't slip with the extreme torque generated by the large bit. You're welcome to borrow either or just make the cut on my drill press. I'm retired now so my schedule is pretty open if you want to come visit.

If someone near you has a CNC machine, it would be quick and clean. If not, I could send you a baltic birch or acrylic template

I have a set of Blu-Mol Bi-Metal hole saws. Not carbide but you are welcome to use them. When do you need them?

Scott, I have a 3" forstner bit that you're welcome to borrow, as well as an adjustable hole cutting bit.

If you know where you want to drill the holes, you can bring your board along and drill the holes using one of my drill presses. That will save you a second trip back to return the bit.

 

[FredP]

I have one you can use. come on by. just call or pm.

If you want to have some fun we can make those holes with a brace and an adjustable expansive bit.

If not, I can offer a few other alternatives. Take your pick: hole saw, forstner bit, circle cutter for the drill press, etc.
