    • Great little set of Forstner bits
I’ve been wanting a set of Forstner bits for a long time and finally had a reason to buy some for a project I’m doing. These are great. They’re sharp, cut great, leave very clean holes requiring no extra cleanup, they cut fast and smooth. The storage case they come in is perfect for keeping them safe and sharp so they’re always ready to use, and the variety of sizes is perfect for me. Very happy with this purchase. ... show more

    • Exceptional Forstner Bit Set

I was looking for a set of forstner bits to cut holes for scroll saw projects. I have used Irwin tools many times in the past and have been satisfied with their quality, so I decided to give the Irwin forstner bits a try after reading the reviews. The case is very well designed. The bits are very sharp and durable. The type of wood I have used the bits on so far has been primarily poplar wood which is a softer hardwood, so I can not attest to how the bits will work with the harder woods, but for what I need them for, they have performed as well if not better than expected. The case that the bits are enclosed in is very secure. Unlike some cases I have had, the bits do not drop out when opened if upside down, they are secure and have to be intentionally removed. It was a very good price and I am very pleased with this forstner bit set. I would highly recommend this bit set. ... show more

    • Great drill bits
Awesome drill bits. I use them all the time. I build a lot of things from scratch using different types of wood and these drill bits work really great. I use them in my drill press all the time. The holes are perfect and true to size. I would recommend them to anyone who does woodworking
