Frequently Asked Questions

What is a KEO Center Drill used for?

A KEO Center Drill creates a conical starting hole for lathe tailstock centers or for subsequent drilling operations. This plain-type, double-end #4 cobalt tool is common in machining and tool-and-die work where precise alignment and repeatability are required.

What are the specifications of the KEO Center Drill 907-000-121?

The KEO Center Drill 907-000-121 is a plain-type, double-end center drill, size #4, with a 60° included angle and 6-inch overall length. It is made from cobalt for heat resistance and durability in industrial drilling applications.

Where to buy a KEO Center Drill worldwide?

3G Electric supplies the KEO Center Drill 907-000-121 to customers worldwide. We handle full logistics, customs clearance, and delivery, ensuring you receive the correct plain-type, double-end #4 cobalt center drill for your machining operations.

How to select the right center drill size for a lathe?

Select a center drill size that matches the diameter of your workpiece and the tailstock center. For general machining, a #4 plain-type center drill like the KEO 907-000-121 works for medium-duty work. Always match the drill angle (60°) to your center's angle for proper seating.
