Description
Product Overview
The KEO 55589-01 6-flute countersink is engineered for high‑performance metalworking. Constructed from premium cobalt alloy, the cutting tip resists wear and maintains sharpness even under demanding conditions. With a 3/4″ body diameter and a 2‑5/8″ overall length, the tool provides a balanced feel and optimal torque transfer. The six‑flute geometry removes material efficiently, producing a clean, round hole with minimal burr formation. Designed as a single‑end cutter, it integrates easily into standard CNC spindle holders or hand‑held toolsets, offering flexibility across a wide range of machining environments.
Usage
This countersink excels in applications that require precise deburring and finishing of drilled holes. It is ideal for aerospace components where tight tolerances and surface integrity are critical, as well as for automotive engine parts, transmission housings, and general industrial fixtures. The tool performs reliably in both high‑speed CNC machining centers and manual drilling stations, making it suitable for batch production as well as prototype development. Its robust cobalt tip tolerates high temperatures, allowing continuous operation without loss of cutting performance.

FAQ
What material is the cutting tip made of?
The tip is forged from high‑grade cobalt alloy, which gives it superior hardness and heat resistance compared with standard high‑speed steel.
Can this countersink be used in a CNC machine?
Yes, the single‑end design fits standard CNC spindle holders, and the six‑flute configuration is optimized for high‑speed automated machining.
What is the recommended cutting speed for mild steel?
For mild steel, a cutting speed of 80‑100 surface feet per minute (SFM) is recommended, with a feed rate adjusted to maintain a chip load of 0.001‑0.002 inches per tooth.
How do I maintain the tool for longest life?
Regularly inspect the flutes for chip buildup, clean with a soft brush, and store the tool in a dry environment. Re‑sharpening is not required for cobalt tips under normal operating conditions.
Is there a warranty on this product?
KEO provides a limited one‑year warranty covering manufacturing defects, ensuring you receive a reliable and high‑quality cutting tool.
