## Customer Reviews

### ⭐⭐⭐⭐⭐ Exceptional Forstner Bit Set
*by B***D on August 19, 2025*

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.

### ⭐⭐⭐⭐⭐ Sharp bits
*by R***H on August 21, 2025*

Nice set of bits. Sharp and cut good.

### ⭐⭐⭐⭐⭐ Good quality bits
*by M***W on June 22, 2025*

Super sharp bits and chew through wood quickly. I use them currently almost exclusively for building birdhouses which I make a lot of in the spring time. Might seem like an insignificant project but these bits chew through cedar better than bits I have used in the past. Leaves and very nice clean hole especially if you use a sacrificial piece behind it.
