The Revbit pilot bit is designed to operate when the teeth of the hole saw are spinning in reverse (opposite of cutting edge), enabling users to create a pilot hole while keeping their hole saw attached to their drill. According to the company, this method increases the life of a hole saw by up to 10 times and will not tear sheetrock or a finished wall’s surface. Made from 100% high speed steel, the bit works on all surfaces and fits all standard hole saws.
