Dottie CO1 Dark Cutting Oil, 1-Quart

For faster, cleaner threading of steel and cast iron, choose Dottie Dark Cutting Oil (CO1). This 1‑quart, pressure‑fortified cutting oil is engineered specifically for ferrous materials, making it ideal for threading conduit and pipe used in security, surveillance and monitoring installations. The chlorinated additive acts as a pressure agent to allow increased tolerance on alloyed or hard‑grained pipe, reducing tool wear and improving cut quality. Because the formula contains active sulphur, it delivers superior lubricity on steel and cast iron but can stain non‑ferrous metals such as copper, brass and stainless — keep a dedicated lubricant on hand for those materials. The oil’s dark color offers visible coverage during use, and the convenient quart size fits easily in service carts or toolboxes for field technicians installing CCTV, access control or network conduit. Trust Dottie CO1 Dark Cutting Oil to speed jobs, protect tooling and deliver consistent results on ferrous threading tasks. Add to your jobsite supplies or order a case for ongoing maintenance and installation projects.
