Product Description

The OSG Micro Drill Bit (MPN 3300315) is a solid carbide micro drill bit with a 3.15 mm diameter, 130° 4-facet point, and TiAlN coating. It features a regular spiral flute design and a specification of 0.1240.

Frequently Asked Questions

What is the OSG Micro Drill Bit 3300315 used for?

The OSG Micro Drill Bit 3300315 is used for precision drilling in hardened steels, stainless steels, and other tough materials. Its 130° 4-facet point and TiAlN coating reduce thrust and improve chip evacuation, making it ideal for micro-machining applications in automotive, aerospace, and mold-making industries.

What are the specifications of the OSG Micro Drill Bit 3300315?

The OSG Micro Drill Bit 3300315 has a 3.15 mm diameter, 130° 4-facet point, and TiAlN coating. It features a regular spiral flute design and a specification of 0.1240. The solid carbide construction provides high wear resistance and rigidity for precise micro-drilling operations.

Where to buy the OSG Micro Drill Bit 3300315 worldwide?

You can source the OSG Micro Drill Bit 3300315 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine OSG tooling for precision machining needs.

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

Select the OSG micro drill bit based on material hardness, hole depth, and required tolerance. For general-purpose drilling in steels, the 130° 4-facet point with TiAlN coating offers good chip control and tool life. Ensure the drill diameter matches your hole size and that your machine spindle speed and feed rate are compatible with solid carbide tooling.
