Ratings & Reviews for IRWIN Marples 2-in x 3-11/16-in Woodboring Forstner bit Drill Bit

Nothing Better

I needed to bore a 2" hole through 3 layers of 2 x 4 in my attic to run security camera BNC wires (8). My regular hole saws couldn't cut more than 2" deep, and took a lot of time to drill through 2" at that. This Forstner bit took about 2 minutes to get through 3 2 x 4's. I had a extension on my drill chuck to make the depth, otherwise the Forstner bit could easily bore through 2 2 x 4's on it's own. The bit appears a little pricy at first, until you realize just how effective it is. All in al...

Very smooth

Purchased this product for a couole of DIY projects. It works great, leaving a very smooth and perfectly round hole. Highly recommend this product.

made quick work out of drilling holes for new gas line

Needs a hex shank, not round

I put a couple of holes in plywood and it was iffy. I had to go very slowly in my drill press. I cranked down so hard on the chuck to tighten it, I was almost unable to undo it. When I was boring/drilling the bit would spin in the chuck if I applied more than a slight amount of pressure. Not sure how it would do in pine, but I'd be afraid to try hardwood. Life would be better if the shank was hex and not round.

Woodboring

I loved this Forstner bit mainly because it cuts smooth around edges.

Works

My husband bought this for a home improvement project. It worked as expected.

Very smooth and cuts clean

Very clean hole saw after drilling through 2 1/2” of wood.

1 1/4 inch Forstner Bit

I needed this bit to drill a 1 1/4 inch flat bottom hole. This bit filled the bill and did a great job.

Hard to Center

Even with the starter tip this drillbit was difficult to keep still and isolated quite a bit before grabbing hold and boring out the hole that I needed.

It makes the cut!!

Bought this bit to install a newel post I was working on. It did a great job!
