These Bosch Rotozip 1/4" straight cut bits have been discontinued and are hard to find. As described on the internet, "Use your ROTOZIP plunge router attachment to create straight grooves, dadoes, rabbets, joints, mortises and general cuts while removing excess material using this Bosch ROTOZIP 75-22852 1/4" straight-cut bit. The carbide tip delivers reliable durability." All new in package. Packaging has wear. Thanks for reading and looking. Aloha!
