Product Description

The OSG Micro Drill Bit (MPN 3300070) is a solid carbide micro drill bit with a 0.7 mm diameter, 140° 4-facet point, and TiAlN coating. It features a regular spiral flute design and a specified attribute value of 0.0276.

Frequently Asked Questions

What is the OSG Micro Drill Bit 0.7 mm used for?

The OSG Micro Drill Bit 0.7 mm is used for precision drilling of small-diameter holes in hardened steels, stainless steels, and other tough materials. Its TiAlN coating and 140° 4-facet point reduce heat and improve chip evacuation, making it ideal for high-speed CNC machining in aerospace, medical, and mold-making applications.

What are the specifications of the OSG Micro Drill Bit 3300070?

The OSG Micro Drill Bit 3300070 has a 0.7 mm diameter, a 140° 4-facet point, and a TiAlN coating. It is made of solid carbide with a regular spiral flute design. The manufacturer part number is 3300070, and it is designed for precision micro-drilling in demanding materials.

Where to buy OSG Micro Drill Bits worldwide?

You can source OSG Micro Drill Bits worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the OSG 3300070 micro drill bit.

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

To select the right OSG micro drill bit, match the diameter (e.g., 0.7 mm) to your hole size, and choose a point geometry like the 140° 4-facet for precise centering. The TiAlN coating suits high-temperature alloys. For regular spiral flutes, use in materials that produce short chips. Consult OSG's technical data for feed and speed recommendations.
