Product Description
Lubrall CUT-4100 is a semi-synthetic metalworking fluid described in the supplied product data sheet for cast iron machining. Its formulation is described as combining naphthenic base oil with synthetic additives to support lubrication and cooling during machining. These properties are intended to help manage friction and heat, support tool life and contribute to surface finish when the fluid is used in a suitable application.
Cast iron machining can be abrasive and may place demands on cutting tools. The product sheet describes CUT-4100 as helping reduce friction and heat build-up and providing corrosion protection for workpieces and equipment. Suitability depends on the machine, process, material grade, water quality and working concentration. Users should confirm the recommended dilution and operating conditions with the manufacturer before use.
RJ Enterprises can assist customers who want to enquire about Lubrall CUT-4100 for industrial machining operations. Ask for the latest technical documentation, recommended concentration, compatibility guidance and current availability. The supplied sheet lists a 210-litre drum. Follow the manufacturer’s directions and site safety procedures for handling, mixing, monitoring and disposal of metalworking fluids.
