Frequently Asked Questions

What is the OSG #12 jobber length drill bit used for?

The OSG #12 jobber length drill bit is used for general-purpose drilling in ferrous metals, stainless steel, and high-temperature alloys. Its TiN-coated cobalt construction provides wear resistance and heat dissipation, making it suitable for production environments where precision and tool life are critical.

What are the specifications of the OSG 15189005 drill bit?

The OSG 15189005 is a #12 jobber length drill bit with a 0.1890-inch diameter, 130° split-point (R-thinning) geometry, and TiN-coated cobalt material. It is designed for general-purpose drilling in tough materials, offering improved chip evacuation and reduced thrust.

Where to buy OSG drill bits in worldwide?

You can source OSG drill bits worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time on the OSG 15189005 or other OSG tooling.

How to select the correct OSG jobber drill bit for stainless steel?

For stainless steel, select an OSG jobber drill bit with TiN coating and a 130° split point, like the #12 (0.1890 inch) model. The coating reduces friction and heat, while the split point minimizes walking. Ensure the drill speed and feed match the material hardness for optimal performance.
