P220 and P320 are medium grits suited for intermediate smoothing. P400 and P600 are fine grits used for surface refinement and achieving a smooth, polished finish on molds and metal parts.\u003c\/p\u003e\n\u003ch4\u003eQ: What does \"vacuum oil-leakage treatment\" mean for these whetstones?\u003c\/h4\u003e\n\u003cp\u003eA: Vacuum oil-leakage treatment is a manufacturing process where oil is drawn deep into the pores of the ceramic stone under vacuum pressure. This saturates the abrasive body, keeping the cutting surface lubricated during use, which significantly improves grinding efficiency, reduces loading, and extends the working life of each stone.\u003c\/p\u003e\n\u003ch4\u003eQ: Are these oilstones suitable for use with water or oil?\u003c\/h4\u003e\n\u003cp\u003eA: These are oilstones designed for use with light honing or mineral oil as a lubricant, which complements the vacuum oil-leakage treatment. Using oil helps flush away swarf, keeps the stone cutting cleanly, and protects the workpiece surface during grinding and polishing operations.\u003c\/p\u003e\n\u003ch4\u003eQ: Can these abrasive files be used on materials other than metal molds?\u003c\/h4\u003e\n\u003cp\u003eA: While these engineered abrasive oilstones are specifically designed for mold work and metalworking applications, they can also be used on hardened steel, carbide, ceramics, and other hard materials that require precise, fine-detail finishing with a slim-profile abrasive tool.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
