BOSCH Roto Zip SC4 1/8-Inch Zip Bit for Wood and Plastic, 4-Pack

I could of found alot more expensive bits than these but my project was small and needed bits in a hurry. These worked great on a very demanding solid wood job although they did not last a really long time and eventually overheated and broke. I was expecting this and was very greatful not to have paid alot for them because I am confident that the expensive ones would of broke and cost me more for the same job. If you are using these on thin or soft material they will work fine for you. Also I have generation 1 rotozip and they eat bits by default! These bits came very fast and I got my job done on time and that to me is all that matters. If you want perfect bits go to the Rotozip site and spend the $.
