Product Description
The KEO Countersink: 100° is a zero-flute, anti-vibration countersink with a 1/2 in body diameter and 5/16 in shank, featuring AlTiN Coated Cobalt construction (MPN 919-002-817). This tool is designed for chatter-free operation in industrial deburring and countersinking applications.
Frequently Asked Questions
What is a KEO 100° countersink used for?
A KEO 100° countersink is used to create a conical recess in a workpiece, typically for a flat-head screw or rivet to sit flush with the surface. The 100° angle is common in aerospace and sheet-metal applications. This zero-flute design reduces chatter and vibration, producing a smoother finish in materials like steel and aluminum.
What are the specifications of the KEO 919-002-817 countersink?
The KEO 919-002-817 is a 100° countersink with zero flutes, a 1/2 in body diameter, and a 5/16 in shank. It features an AlTiN (aluminum titanium nitride) coating on cobalt substrate, which enhances wear resistance and heat tolerance. This anti-vibration design is ideal for precision chamfering in hard metals.
Where to buy KEO countersinks worldwide?
KEO countersinks, including the 919-002-817, are available to order through 3G Electric, a global industrial equipment supplier. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact our team for pricing and lead time; we source and deliver genuine KEO tooling to your facility.
How to select the right KEO countersink for my application?
Select a KEO countersink based on the screw head angle (e.g., 100° for aerospace), material hardness, and desired finish. For hard metals, choose an AlTiN-coated cobalt variant like the 919-002-817. Zero-flute designs minimize vibration on CNC or manual machines. Match the body diameter to the hole size and ensure the shank fits your toolholder.
