2-flute Carbide Drill Bit Sets (DC208) - 1/8 in. (0.125 in.)
Think & Tinker 2-flute carbide drill bits were designed and optimized for the fabrication of printed circuit boards on a wide variety of substrates. Decades of design improvements has expanded their application range to hard and soft woods, metals, glass and carbon-fiber composites and reconstituted minerals.
