14:50 How to Sharpen a Speckled Fluorocarbon Step Drill Bit

Step drill bits (often called unibits) are essential for drilling clean, multi-sized holes in metal and plastic. High-performance variants feature a speckled fluorocarbon coating, which minimizes friction, prevents heat buildup, and stops debris from sticking. However, even the best coated bits eventually become dull.Sharpening a step drill bit requires a different approach than standard twist drills. The key is to sharpen only the flat cutting edge (flute), leaving the stepped diameters and the speckled protective coating untouched.
