Frequently Asked Questions

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

A KEO plain-tip center drill creates precise conical starting 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 in ferrous materials.

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

The KEO center drill #4 1/2 has a 60° included angle, 8-inch overall length, and double-end plain tip. It is made from AlTiN coated high-speed steel, with manufacturer part number 907-000-760. The coating improves wear resistance in hard-to-machine alloys.

Where to buy KEO center drills worldwide?

3G Electric supplies KEO center drills worldwide, handling full logistics and customs clearance. As a global industrial sourcing partner, we provide genuine KEO tooling like the #4 1/2 plain-tip drill (MPN 907-000-760) to customers across machining, aerospace, and automotive industries.

How to select the right KEO center drill size?

Select a KEO center drill size (#4 1/2, #5, etc.) based on the workpiece diameter and required center hole depth. The 60° angle is standard for general turning. For hard materials, the AlTiN coating on high-speed steel reduces edge buildup. Always match the drill to your lathe tailstock taper.
