KEO Countersink: 100°, 6 Flute, 1 1/2 in Body Dia, 3/4 in Shank

A KEO 100° countersink with six flutes is used in machining to create a smooth, countersunk hole for flat-head screws or rivets. The 100° angle is common in aerospace and sheet-metal work. The cobalt construction provides heat resistance for use on hard materials like stainless steel.

The KEO 919-000-827 is a 100°, six-flute countersink with a 1 1/2 in body diameter and a 3/4 in shank. It is made from cobalt for durability in high-temperature applications. This smooth-finish design reduces chatter and delivers a clean, consistent countersink in metalworking.

3G Electric supplies KEO countersinks like the 919-000-827 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. As a global industrial sourcing partner, we provide genuine KEO tooling without requiring you to manage multiple suppliers or international shipping complexities.

Select a KEO countersink by matching the flute count and angle to your fastener and material. Six-flute designs like the 919-000-827 provide smoother finishes on harder metals. Cobalt is ideal for high-heat machining. Always verify shank diameter (3/4 in) fits your tool holder and that the body diameter (1 1/2 in) clears the workpiece.
