What is the best way to remove burrs from a land?

• A. File
• B. Sandpaper
• C. Grinder
• D. Chisel

Answer: (A)

Deburring a land requires removing the sharp burrs without changing the edge geometry. A hand file is best because it gives precise control over material removal and lets you feel the burr as you work along the edge. This lets you follow the contour of the land, keeping the edge flat and true for a proper fit. Use light, steady strokes and maintain the edge geometry; finish with a fine file or emery cloth if a smoother surface is needed. Sandpaper can’t shape a narrow edge as precisely and tends to clog, a grinder is too aggressive and can remove too much material or round the edge, and a chisel risks gouging the surface.
