Frequently Asked Questions

What is the OSG Micro Drill Bit 0.31 mm used for?

The OSG Micro Drill Bit 0.31 mm is used for precision drilling of small-diameter holes in hardened steels, stainless steels, and other tough materials. Its 140° 4-facet point and TiAlN coating reduce thrust and improve chip evacuation, making it ideal for micro-machining applications in tool and die, medical device, and electronics manufacturing.

What are the specifications of the OSG Micro Drill Bit MPN 3300031?

The OSG Micro Drill Bit MPN 3300031 has a 0.31 mm diameter, 140° 4-facet point, and TiAlN coating. It is made of solid carbide with a regular spiral flute design. The attribute 0.0122 corresponds to the drill's decimal-inch equivalent. This bit is designed for high-precision micro-drilling in demanding materials.

Where to buy OSG Micro Drill Bits worldwide?

How to select the correct OSG micro drill bit for my application?

Selecting the correct OSG micro drill bit requires matching diameter, point geometry, and coating to your material and hole depth. For hardened steels, use a TiAlN-coated bit with a 140° point to reduce cutting forces. Ensure your spindle speed and feed rate are appropriate for the 0.31 mm diameter to prevent breakage. Consult OSG's technical data for specific parameters.
