Tri-Cone Roller Rock Drill Bit

I have to sell my Heavy-duty steel tri-cone roller rock drill bit. It is painted blue to prevent corrosion. This tool has three rotating cones with integrated teeth for drilling through rock. The base has a large tapered threaded connection for attachment to a drill string. Visible wear and paint chipping are present on the body and teeth. Pickup in Saddleridge Calgary Shipping is available at the expense of the buyer.
