Overview

- PreciseBits Carbide Micro Drills - Wire Gauge (Number) Sizes 40-59

High-quality carbide micro drill featuring a shallow point angle that minimizes backside breakout and splintering while the geometry and back tapered flutes virtually eliminate top surface splintering. The tip geometry produces shallow glue pockets for anchoring inlaid components.

A great choice for such applications such as drilling hardwoods, non-ferrous metals, inlay pockets for mother-of-pearl dots and drill printed circuit board substrates.
