Important Use Note

Solid carbide drills are rigid and wear resistant, but they are also brittle. Use a stable holder, low-runout spindle, drill press, mill, CNC machine, pin vise, or other controlled setup. Keep the drill aligned with the work and avoid side pressure, bending, or forcing the tool.

The exact drill style, flute length, point geometry, manufacturer, ring color, and cosmetic appearance may vary across the assortment. The included diameters and quantities are shown in the size chart above.
