Bosch DQCE1012 Daredevil QC Spade Drill Bit 12 Inch 1/4" Shank Extension

excellent bit holding power These extensions are quite useful and very low profile compared to the exact same style I have from Black and Deck. The mechanical removal of the parts holds very tightly and requires a little force to remove the bits, but it's not too awful. I particularly enjoy that, unlike the Black and Deckers, the Bosch is impact-rated. Bosch is an incredible product that I would suggest to anyone who needs extensions. The bosch are also easy to use when it comes to the blue color sliding to get the bit out. Bosch has a superior retention ring to hold bits firmly.
