OSG Micro Drill Bit: 3.29 mm, 140° 4-Facet Point

This OSG solid carbide micro drill bit is designed for precision drilling in hardened steels and abrasive materials. The 140° 4-facet point reduces thrust and improves hole accuracy, while the TiAlN coating extends tool life at elevated temperatures. Common applications include mold and die making, aerospace components, and medical device manufacturing.

The OSG Micro Drill Bit 48172329 has a 3.29 mm diameter with a 140° 4-facet point geometry. It features a TiAlN coating on a solid carbide substrate with a regular spiral flute design. The manufacturer part number is 48172329, and the decimal equivalent is 0.1295 inches. It is suitable for high-precision drilling in hard materials.
