RETRAC & REAMING BITS

Retrac bits are designed for drilling conditions where fractured rock, unstable hole walls or bit jamming may occur. The extended guiding skirt improves hole stability and straightness while allowing easier bit retraction. Reaming bits are used to enlarge existing drill holes formining, quarrying, tunneling and construction drilling.
