Choosing a Carbide Drill Bit Set
-
Incremental sets: Good for keeping a small range of nearby drill sizes on hand.
-
Metric sets: Useful when your project, drawing, or specification calls for metric drill sizes.
-
Fractional inch sets: Useful for common fractional drill sizes used in shop, hobby, repair, and general drilling work.
-
50-piece and larger sets: Better when you need a broader assortment of micro drill sizes for PCB work, prototyping, testing, or mixed projects.
-
Carburetor jet sets: Configured for carburetor jet sizing, cleaning, tuning, and small precision hole work.
Most sets include solid carbide micro drill bits with standard 1/8" shanks, commonly used for PCB drilling, precision CNC work, plastics, composites, brass, aluminum, and other appropriate materials.
