What Customers Are Saying

This set of Forstner bits generally performs well for most woodworking projects, producing clean, smooth holes, especially when used with a drill press. The wide range of bit sizes is a key benefit. However, some customers reported quality issues like dull or damaged cutting edges, as well as challenges using the bits in a handheld drill. Overall, this is a reasonably priced and functional set suitable for hobbyist and DIY use, but may not meet the needs of professional or heavy-duty users.

Great Forstner Bit Kit

Would Recommend

This is a well compiled kit of Forstner bits. I only needed two sizes, but ended up getting the whole kit because the price for the kit was better than the cost of two or three single bits, and it came with a case. I have always gotten good usage out of my Irwin tools, so this was a no brainer for me. It did the job I needed it to do. Now, to find other projects to use it on.

Worked well, but....

Would Recommend

It did exactly as I needed. But I needed one specific size which I could not get as a single unit or in a smaller package. So I had to buy the largest quantity which made my overall project more expensive.

Gets the job done

Would Recommend

I used this 14-piece IRWIN Marples Forstner bit set while working on a staircase newel post, and it performed really well. The bits cut clean, flat-bottom holes and stayed steady without wandering, which was important for the precise placement I needed on the post. The edges were sharp right out of the box and went through the wood smoothly without a lot of tear-out. I also liked having multiple sizes available in the set so I could match the exact hole size for the hardware I was installing. ...

Not too bad

Would Recommend

I just purchased the 14 piece set of Forster bits today for a project I am working on. I used a cordless drill and drilled 18 holes at 1 3/8" deep. The 3/4" bit worked perfectly. Granted, as some have mentioned the bits aren't esthetically great but worked fine for a DIYer. Some also mentioned that these bits slip in the drill, come on guys put your purse down and tighten the chuck! I've seen so many guys grab the drill hold the bit and spin 'er up. That's just not tight enough from my experienc...

Will make holes constantly.

Like the case and the quantity of bits. Down side the bits can slip in the drills chuck. So 4 stars.

Lots of bit sizes.

Would Recommend

Needed to make some holes in a piece of plywood and what not. This is a comprehensive set with just about any size you'd ever need.
