Carbide Tipped vs. Steel, No Contest! - Router Bits & More

Carbide Tipped, No Contest! Router bits made of steel are cheaper, but that is the only advantage. Carbide-tipped router bits maintain a sharper cutting edge longer than steel, produce a better finish when cutting, and provide cleaner and smoother cuts. They also withstand very high temperatures better than steel, allowing for faster machining.

Chromium Carbide Appliion - Nanoshel

Chromium Carbide-based coatings have a wear resistance which is between two and a half and five times better than hard chrome plating and do not suffer from effluent disposal problems. They are therefore finding increasing use at the expense of hard chrome plating, particularly if wear resistance is important or if a thick coating is required on a large part.
