Big Horn 18939#11 5pc. Countersink Set W. L. Fuller 10393011C

American made, excellent quality and very easy to use.

Awesome bit set.

Product works great but twice i received this product with the storage case split in two in the same spot. There was no damage to the shipping container and adequate packing inside. I believe that it is a product defect and the company should look at changing their manufacturing process to eliminate this defect as this is quite an expensive but useful product. Otherwise i would have given this 5 stars.

This format of tapered drills is my personal favorite. The available stops while not used very much are a useful accessory. The range of sizes is great. The box is a nice way to package and retain all of the pieces in a handy unit, and is for sure more durable than most of the "plastic" boxes these sets seem to be packaged in nowadays. The plug cutter works well in a hand held drill, even better in a drill press.This is my third set of Fuller bits in three and a half decades. I pass the older sets on and purchase a new set when it appears to be about that time.While I have succeeded in misplacing a couple of the bits over the years, I have yet to break one. Kudos to Fuller for a well made set of bits.

Should have bought these years ago as they are razor sharp to help drive precise holes in all types of wood (oak, baltic birch, pine...).if you can afford them get them and you wont be dissapointed
