Frequently Asked Questions

What is a KEO plain-type center drill used for?

A KEO plain-type center drill creates precise 90° center holes in workpieces for lathe turning or grinding operations. The double-end design extends tool life, and the AlTiN coating on high-speed steel reduces friction and heat, making it suitable for machining steel and other metals.

What are the specifications of the KEO #4 1/2 center drill?

The KEO #4 1/2 center drill is a double-end, plain-type tool with a 90° point angle and 4-inch overall length. It is made of AlTiN-coated high-speed steel (MPN 907-000-769). This size is commonly used for medium-duty centering work in industrial machining.

Where to buy KEO center drills worldwide?

How to select the right KEO center drill size?

Select a KEO center drill size based on the workpiece diameter and the lathe center's dimensions. The #4 1/2 size suits medium workpieces. Ensure the 90° angle matches your tailstock center. For harder materials, the AlTiN coating on KEO high-speed steel drills improves wear resistance and cutting performance.
