Product Description

The OSG Micro Drill Bit (MPN 3300161) is a solid carbide micro drill bit with a 1.61 mm diameter, 140° 4-facet point, and TiAlN coating. It features a regular spiral flute design and a decimal equivalent of 0.0634 inches.

Frequently Asked Questions

What is the OSG Micro Drill Bit 1.61 mm used for?

The OSG Micro Drill Bit 1.61 mm is used for precision drilling 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 aerospace, medical, and mold-making industries.

What are the specifications of the OSG Micro Drill Bit 3300161?

The OSG Micro Drill Bit 3300161 has a 1.61 mm diameter, a decimal equivalent of 0.0634 inches, a 140° 4-facet point, and a TiAlN coating. It is made of solid carbide with a regular spiral flute design. These specs enable high-precision drilling in hard materials with extended tool life.

Where to buy OSG Micro Drill Bits worldwide?

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., 1.61 mm) to your hole size, and choose a point geometry like the 140° 4-facet for reduced walking on curved surfaces. Consider the TiAlN coating for heat resistance in hard materials. Always verify flute design (regular spiral) for chip clearance.
