Ratings & Reviews for IRWIN Marples 1-1/2-in x 3-11/16-in Woodboring Forstner bit Drill Bit

Forstner bit

I. tried unsuccessfully to drill a hole in hardwood with my old, dull 2 inch bit . I bought this one and it worked well. All good Forstner bits are too expensive in my opinion in my opinion

Great bit, good price.

Just the bit I needed for installing cabinet hinges.

1 1/2 inch bore bit

This bit is the clear choice over paddle bits. Drills clean, efficiently and perfect size for a plug.

Forstner bit

Bit did exacter what it needed to--fit into my drill press with wobble

Very Poor Quality

This might work ok for rough cuts on 2 x 4's, but not at all a quality woodworking bit. It took a lot of work just to clean up the burs and rough spots in order to actually sharpen it. The design didn't allow sharpening without grinding parts out first. Definitely will never buy this brand again.

Bad design

It keeps slipping. I could not make a single hole.

Drill Bit

Building a ladder, had to drill holes for the rungs. This drill bit CRdid the job.

Sharp, reasonably priced bit

Cuts a very clean, accurate hole. When hole depth got beyond 1.5" or so it required slower progress and clearing the chips out of the hole often. Bit can get very hot so watch your speed and don't let it get hot enough to draw the temper of the steel. This is a problem with all bits of this style however. I had to drill several holes through a mix of mahogany, sycamore, and cypress. Holes were from 1-3/4" to 2-3/4" deep, I took my time and gave the bit a break in between holes. I would not ...

Awesome but

Needed a hole in a desk for wires. Bit bore through without an my issue. Great buy

GOOD BIT...

Nice sharp bit and works just as good as more expensive bits. Drilled quite a few holes and it has kept it's edge.

Arbor for chubbier Birdhouse 'Harbors'

I purchased this arbor to go with the comparable set. This next size up, for larger 'plumpier' species worked very will. The material used was pine and I naturally go slow making the holes. This larger arbor worked very well, cleaned well during drilling and left a clean hole entrance for future birds. Very pleased!

Works TERRIFIC

Actually did the hinges on our cabinets with this and it worked wonderful!

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.
