4-1/4" Iron Fist w/Dome Cutters | 2-1/8" Tri-Con Connection
When loose ground and cobbles threaten to derail your pilot shot, the Iron Fist pilot bit keeps you in control. Its dome-style carbide cutters excel in fractured formations, while the Tri-Con™ connection makes changeouts simple. The result: fewer delays, cleaner starts, and a bore you can trust to finish strong.
