In precision machining, performance doesn’t stop at tool design, it extends to the finishing process. At Carbide Tool, every detail matters, which is why black oxide coating is a standard part of our manufacturing and repair process. This final step helps protect your tools, extend their lifespan, and ensure they return to you performing like new.
What Is Black Oxide Coating?
Black oxide is a controlled chemical conversion coating applied to steel tools. Rather than adding thickness, it creates a uniform protective layer that enhances surface properties without altering critical dimensions. This makes it ideal for high-precision cutting tools where accuracy and consistency are non-negotiable.
Reduced Corrosion and Wear
One of the primary benefits of black oxide coating is improved resistance to corrosion and wear. The coating helps shield tools from moisture, oxidation, and friction during use, reducing premature degradation. This added protection allows tools to maintain cutting performance longer, even in demanding machining environments.
Maintaining Tight Tolerances
Precision is at the core of everything we do at Carbide Tool. Black oxide coating does not build up on the surface, which means your tools retain their exact geometry and tolerances. After repairs or reconditioning, tools are returned in like-new condition, meeting the same strict dimensional requirements as when they were first manufactured.
A Final Step for OEM-Level Quality
At Carbide Tool, black oxide coating is applied only after final inspection. This ensures every tool meets OEM specifications before it leaves our facility. By integrating black oxide into our finishing process, we help preserve accuracy, protect the tool during handling and shipping, and deliver consistent quality you can rely on.
Black oxide coating is more than a finishing touch, it’s a commitment to performance, longevity, and precision. By incorporating this process into every applicable order, Carbide Tool ensures your tools are protected, accurate, and ready to perform at the highest level from the moment they arrive.
