Review on Enhanced Meich Forstner Drilling Cemented Counterbore: Efficiency and Precision at Its Best by Will Ridpath

Very sharp and good quality. I took off a star because I would have preferred it to be in inches rather than millimeters. Each bit comes in its own protective plastic case to keep it sharp and prevent rusting. A good price of $10 minus a coupon for an additional 5% off plus free Prime shipping and no sales tax beats buying at a retail store. The drill bit package includes 5 bits 15mm/20mm/25mm/30mm/35mm. It looks like they could be easily sharpened with a small file. They are for wood only so don't be fooled by the description and do not use them on metal. Should work for other materials like drywall etc. I like them and recommend them.
