Abstract

A tool bit includes a plurality of fins each having first and second ends and extended radially and longitudinally and including the second end thereof forming two opposite lateral sides each including a reinforcing section extended therefrom. Two adjacent fins of the plurality of fins form a recess therebetween, which has a curved periphery interconnecting two adjacent reinforcing sections of the two adjacent fins. Each fin defines a first length from the end thereof to the curved periphery of the recess extended from the second end thereof. The first length is smaller than a second length defined between two opposite peripheral sides of a hexagonal periphery of a connecting end of the tool bit.
