Willow E-file Bit Guide

Great little book , very informative to refer too for your drill bits , highly recommend

I LOVE the idea of this book! I didn’t really know what it was until it arrived but I was soooo impressed to see it contains all the Efile bits with pictures and all the details about when to use it, what speed to use it, what its best for etc. Such a brilliant idea and beautifully designed and made.

Very thorough and very handy
