“Don't waste your money on those cheapie Ryobi or Hitachi countersinks available at Home Depot and Lowes. The W.L. Fuller countersinks are the finest available--sharp, durable, and well-made. I am a professional cabinetmaker, and every cabinetmaker in our shop has a set of Fuller countersinks. Nice, clean countersinks everytime.
The tapered bits this set comes with can be swapped out with regular drill bits. The tapered bits work well for wood screws, but it seems like few people use wood screws anymore. We use sheet metal/drywall screws exclusively, and find them far superior. Just put regular drill bits in your Fuller countersink set, and you're ready to roll. Save the tapered bits for acrylic and plexiglass, as they won't crack or chip the material like straight bits do.
W.L. Fuller sells an unbelievable line of specialty bits and cutting tools, and their quality is top rate on all their tools. It's a shame Amazon only sells the countersinks, but if you need a set, this is the best price out there.
Fuller is a family owned and operated business out of Warwick, Rhode Island. At a time when more and more tool manufacturing jobs are being lost to near-slave labor in China, it's great to see some Yankee ingenuity cranking out products that will still be rockin' when all that Chinese junk has been re-recycled back into beer cans.”
