Product Description

The KEO Countersink: 110° is a general purpose three-flute countersink made of TiN coated high speed steel, with a 1 1/2 in body diameter and a 3/4 in shank (MPN 51501-TIN). This KEO tool is designed for precise chamfering and deburring in industrial machining applications.

Frequently Asked Questions

What is a KEO 110° countersink used for?

A KEO 110° countersink is used to create a conical recess in a workpiece, typically for flathead screws or rivets. The 110° angle is common in aerospace and sheet-metal applications. This three-flute design provides smooth cutting and reduces chatter, making it suitable for general-purpose deburring and countersinking in metal.

What are the specifications of the KEO 51501-TIN countersink?

The KEO 51501-TIN is a 110° countersink with three flutes, a 1 1/2 in body diameter, and a 3/4 in shank. It is made from TiN-coated high-speed steel for extended tool life. This general-purpose tool is designed for use in drill presses or handheld tools on ferrous and non-ferrous materials.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 51501-TIN to customers worldwide. As a global industrial sourcing partner, we handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this TiN-coated high-speed steel tool.

How to select the right countersink for metalworking?

Select a countersink based on the screw head angle (e.g., 82° or 110°), material hardness, and desired finish. For general-purpose metalwork, a three-flute TiN-coated high-speed steel tool like the KEO 51501-TIN offers durability and chip evacuation. Match shank diameter to your chuck size and body diameter to the recess depth needed.
