KEO

KEO is a manufacturer of precision cutting tools, primarily known for its center drills, countersinks, and keyseat cutters. The company, based in the United States, has a long history in the industrial tooling sector, dating back to the early 20th century. KEO's product line focuses on tools used for creating accurate starting points for drilling, chamfering holes, and milling keyways in shafts. Their catalog includes plain-tip, bell-tip, and radius-tip center drills, available in various sizes (from #4/0 to #13) and point angles (60°, 90°, 118°). These tools are offered in double-end and single-end configurations, with materials ranging from high-speed steel (HSS) to cobalt and carbide, and coatings such as TiN (titanium nitride) and AlTiN (aluminum titanium nitride) for enhanced wear resistance. KEO also produces left-hand center drills for specialized applications and keyseat cutters in carbide for precision keyway milling. The tools are designed to meet standard industrial tolerances, with overall lengths varying from 1 1/4 inches to 4 inches, depending on the type and size. 3G Electric supplies KEO cutting tools globally, offering a range of these products for plant engineers, maintenance managers, and procurement specialists who require reliable tooling for machining operations. The inventory includes both standard and coated variants, supporting applications in metalworking, automotive, aerospace, and general manufacturing. KEO's tools are specified by their dimensional accuracy and material composition, making them suitable for repetitive, high-precision tasks. 3G Electric provides logistics support to ensure availability of these tools across different regions, with no geographic restrictions on distribution.

Frequently asked questions

Common questions about KEO from 3G Electric.

What types of center drills does KEO offer?

KEO offers three main types of center drills: plain-tip, bell-tip, and radius-tip. Plain-tip center drills have a straight point for general-purpose centering. Bell-tip center drills feature a flared end for creating a countersunk hole, and radius-tip center drills have a rounded tip for reducing stress concentration. These are available in double-end and single-end configurations, with sizes from #4/0 to #13 and point angles of 60°, 90°, or 118°.

What materials and coatings are available for KEO center drills?

KEO center drills are made from high-speed steel (HSS), cobalt, or carbide. Coatings include TiN (titanium nitride) for increased hardness and lubricity, and AlTiN (aluminum titanium nitride) for higher temperature resistance and extended tool life. Uncoated HSS and cobalt options are also available for standard applications.

Are KEO keyseat cutters available in carbide?

Yes, KEO produces small keyseat cutters in carbide, such as the straight-tooth type with diameters like 1/8 inch and thicknesses like 1 mm. These cutters are designed for precision keyway milling in hardened materials and are available with 4 teeth for efficient cutting.

What is the difference between double-end and single-end KEO center drills?

Double-end center drills have two usable ends, allowing the tool to be flipped when one end wears out, doubling its service life. Single-end center drills have only one cutting end and are typically used for applications requiring a specific geometry or when space constraints limit tool length.

Can KEO center drills be used for left-hand rotation?

Yes, KEO offers left-hand (LH) center drills, such as the bell-tip type in size #11 with a 60° angle. These are designed for machines with left-hand spindle rotation or for specific applications where conventional right-hand tools are not suitable.

Does 3G Electric supply KEO products?

Yes — 3G Electric (S) Pte. Ltd. supplies KEO products. We stock the KEO catalog and supply genuine factory-original products with full manufacturer warranty and technical support.
