Product Description

The KEO Countersink: 90° is an Anti-Vibration Zero-Flute Countersink, featuring a 1/2 in body diameter and 5/16 in shank, with AlTiN Coated Cobalt construction (MPN 919-002-826). This zero-flute design minimizes vibration during operation, and the 90° angle is suited for standard countersinking tasks.

Frequently Asked Questions

What is a KEO zero-flute countersink used for?

A KEO zero-flute countersink creates a clean, chatter-free 90° chamfer around a drilled hole. It is used in machining and metalworking to prepare holes for flat-head screws or deburr edges. The AlTiN-coated cobalt construction provides heat resistance and extends tool life in ferrous and non-ferrous materials.

What are the specifications of the KEO 919-002-826 countersink?

The KEO 919-002-826 is a 90° zero-flute countersink with a 1/2 in body diameter and a 5/16 in shank. It is made from AlTiN-coated cobalt for durability. This anti-vibration design reduces chatter and produces a smooth finish. It is suitable for general industrial deburring and countersinking applications.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle (90° is standard for flat-head screws), the hole diameter, and the material being machined. For hard or abrasive materials, choose AlTiN-coated cobalt for heat resistance. Ensure the shank diameter matches your tool holder. Zero-flute designs minimize vibration for a cleaner finish.
