HSS in the HSS Cobalt Drill Bit is high-speed steel, which is a tool steel with high hardness, high wear resistance and high heat resistance, also known as high-speed tool steel or high-speed steel, commonly known as white steel. High-speed steel cutters are tougher and easier to cut than ordinary cutters.
Titanium-plated drill bits are also high-speed steel titanium-plated. Titanium-plated steel drill bits: extremely high hardness (hardness can reach HRC78, provided that real industrial plating is required, not the decorative plating)
The point is that more than 95% of the titanium-plated drill bits on the market are fake, because most of the propaganda titanium-plated drill bits are only decorative plating, just to achieve the effect of the color of the titanium-plated drill bit, so in order to distinguish between these two kinds of titanium-plated drill bits, fake It's called decorative plating,and it is really called industrial coating.
