Frequently Asked Questions

What is the OSG #5 screw machine drill bit used for?

This OSG #5 drill bit is designed for high-speed drilling in production environments. Its 130° R-thinning point and TiN-coated cobalt construction provide wear resistance and chip evacuation, making it suitable for machining steel, stainless steel, and other ferrous materials in automated or manual setups.

What are the specifications of the OSG 10205505 drill bit?

The OSG 10205505 is a #5 screw-machine length drill bit with a 0.2055-inch diameter. It features a 130° R-thinning point and a TiN-coated cobalt substrate for extended tool life. This general-purpose bit is optimized for rigid, high-speed drilling applications in industrial machining.

Where to buy OSG drill bits worldwide?

3G Electric supplies OSG drill bits like the 10205505 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. As a global industrial sourcing partner, we provide genuine OSG tooling with technical support for your machining requirements.

How to select the correct OSG screw machine drill bit size?

Select the OSG drill bit size based on your hole diameter and material. For the #5 bit (0.2055 inch), confirm your workpiece material and machine rigidity. Use a 130° point for general steel drilling; TiN coating reduces friction. Always match the drill length to your setup for optimal chip clearance.
