Junk Mills

Logan Junk Mills are hard-faced with sintered tungsten carbide particles that mill away stuck fish that can not be retrieved with conventional fishing methods. These tools are highly resistant to impact and their super rates of penetration result in fewer round trips. Their maximum useful life is enhanced by their self-sharpening feature.
