Product Description

OSG General Purpose Cobalt Screw-Machine Length Drill Bits.

Frequently Asked Questions

What is the OSG #47 screw machine drill bit used for?

The OSG #47 screw machine drill bit is used for precision drilling in automated machining centers and screw machines. Its 130° split-point with R-thinning reduces thrust, making it ideal for high-speed production of small-diameter holes in steel, stainless steel, and cast iron.

What are the specifications of the OSG 10078505 drill bit?

The OSG 10078505 is a #47 screw machine length drill bit with a 0.0785-inch diameter. It features a 130° R-thinning point and TiN-coated cobalt construction for heat resistance and extended tool life. It is designed for general-purpose drilling in ferrous materials.

Where to buy OSG drill bits 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 10078505 and other precision tooling.

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

Select the OSG screw machine drill bit by matching the wire gauge number or decimal diameter to your hole size requirement. For the #47 bit, the diameter is 0.0785 inches. Ensure the 130° split-point and TiN coating suit your material—cobalt grade handles harder steels. Consult OSG's application data for optimal speeds and feeds.
