Fully supported carbide head that gives longer life; cleaner and more concentric holes for better fixing retention.
Open head design ensures faster drilling.
Has a maximised central core that enables more efficient energy transmission to the drill bit head.
The functional length of a bit determines how deep a hole can be drilled, and also determines the stiffness of the bit and accuracy of the resultant hole.
