Stubby Length Drill Bits - Fractional Series Ideal for production cut- ting of metal. The shorter "stubby flute " make it less likely to break when pressure is applied; compared to standard jobber length bits of the same diameter. They also come in handy in applications where space is a problem. For instance, 3/8 stubbys are often used to drill holes in the top of doors: Many times there is not enough room between the top of the door and ceiling for a full jobber length bit and a drill motor. Manufactured in the U.S.A.
