Product Description

The KEO Center Drill is a high-precision radius-tip center drill, model #7 with a 60° angle and 3 1/4 inch overall length, made from high-speed steel. This double-end tool, manufactured by KEO under part number 906-000-152, is designed for creating accurate center holes in workpieces.

Frequently Asked Questions

What is a KEO Center Drill used for?

A KEO Center Drill creates precise 60° center holes in workpieces for lathe operations or subsequent drilling. The radius tip reduces breakage and improves hole accuracy. It is commonly used in metalworking, toolmaking, and precision machining where exact centering is critical.

What are the specifications of the KEO Center Drill #7?

The KEO Center Drill #7 (MPN 906-000-152) has a 60° included angle, 3 1/4 inch overall length, and is made from high-speed steel. It is a double-end tool, allowing two usable ends. The radius-tip design enhances durability and centering accuracy in hard materials.

Where to buy KEO Center Drills worldwide?
