Product Description

The KEO Countersink: 120° is a fast-cutting single-flute countersink made of TiN Coated High Speed Steel, with a 1 3/4 in body diameter and a 3/4 in shank (MPN 919-000-178). This KEO tool is designed for efficient deburring and chamfering operations.

Frequently Asked Questions

What is the KEO 120° countersink used for?

The KEO 120° countersink is used to create a conical recess for flat-head screws in metalworking and machining applications. Its single-flute design provides fast, chatter-free cutting in steel, aluminum, and other materials, making it ideal for deburring and countersinking holes in industrial manufacturing.

What are the specifications of the KEO 919-000-178 countersink?

The KEO 919-000-178 countersink has a 120° included angle, 1 flute, 1 3/4 in body diameter, and 3/4 in shank. It is made of TiN-coated high-speed steel for wear resistance. This single-flute design is optimized for fast cutting and chip evacuation in production environments.

Where to buy the KEO 919-000-178 countersink worldwide?

You can source the KEO 919-000-178 countersink through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply KEO tooling to manufacturing facilities internationally.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the screw head angle (e.g., 120° for metric flat-head screws), material hardness (TiN-coated HSS for steel), and shank size matching your tool holder. For deep holes or production runs, single-flute designs like the 919-000-178 offer faster cutting and better chip clearance than multi-flute alternatives.
