Famag have Excellent forstner bits and I used only this manufacturer

Jim Hall (Ottawa, CA)

I have a large collection of Forstner bits accumulated over the years, some from well known brands.
I recently needed a metric size and picked up a FAMAG bit. I was absolutely astounded at its performance.
It cut cleanly and effortlessly through hard maple - no comparison with the bits I already have.
I will now being replacing all my existing bits as needed.
