Design And Fabrication Of Drill Bit Reconditioning Fixture

Mechanical Engineering

Drill bits have so far been manually grinded in order to restore their functionality conforming to specified lip angle. Usually drill bits have been grinded manually by some skilled operators. Due to this sometimes imperfections may occur, leading to reduced drill bit’s efficiency. This project aims at developing a fixture which is capable of holding drill bit firmly against the grinding wheel during reconditioning or re-sharpening process making it less susceptible to minor deviations from specified lip angle. This fixture could be mechanically operated by even a less skilled operator. Also this fixture will eliminate the need for tool inspection during or after reconditioning. It also reduces wastage of drill tools which have been not preferred after a wearer condition. In addition, the cost of buying a new drill bit can be reduced by using this fixture and can prolong the lifespan of the drill. It also helps the drill bits to be more economic. However, this fixture is a hope that will be a successful product and be able to use to sharpen blunt drill bits to the exact angle safely and effectively.
