Description
Product Overview
The KEO 53523 is a premium single‑end countersink designed for high‑performance machining of hard metals. Constructed from cobalt steel, the tool inherits the toughness of high‑speed steel while adding cobalt for superior heat resistance and wear resistance. A titanium nitride (TiN) coating blankets the cutting edges, delivering a gold‑colored ceramic layer that reduces friction, increases hardness, and prolongs tool life. The 90° point angle ensures a clean, precise entry into the workpiece, while the 3/8″ round shank offers universal compatibility with a wide range of collet and chuck systems. With a body diameter of 5/8″ and a compact length, the countersink balances rigidity and maneuverability, making it suitable for both manual and CNC applications.
Usage
This countersink excels in environments where stainless steel, nickel alloys, and other tough materials are processed. The tool’s right‑hand cut spiral flutes evacuate chips upward, preventing clogging and maintaining a smooth cutting action even at high feed rates. It is ideal for creating clean, deburred holes for fasteners, bolts, and screws in aerospace, automotive, and medical device manufacturing. The TiN coating allows operators to increase spindle speeds without sacrificing tool integrity, reducing cycle times and improving overall productivity. Whether mounted in a handheld drill press or integrated into a CNC spindle, the 3/8″ shank fits standard toolholders, enabling quick changeovers and minimizing downtime.
Why Choose Us
Choosing the KEO 53523 means selecting a tool backed by decades of cutting‑tool expertise. KEO Cutters manufactures each piece under strict quality‑control protocols, ensuring consistent geometry and coating thickness across every batch.

FAQ
What materials can this countersink effectively cut?
The KEO 53523 is optimized for stainless steel, nickel alloys, and other hard metals where cobalt steel and TiN coating provide the necessary hardness and heat resistance.
Can I use this tool in a CNC machine?
Yes, the 3/8″ round shank is compatible with standard CNC collet systems, making it suitable for both manual and automated machining setups.
How does the TiN coating improve performance?
TiN creates a hard, low‑friction surface that reduces tool wear, allows higher spindle speeds, and helps achieve a smoother finish on the workpiece.
What is the recommended spindle speed for stainless steel?
For stainless steel, a spindle speed between 2,500 and 3,500 RPM is typical, but you should adjust based on material thickness and feed rate.
Is there a warranty or replacement policy?
KEO provides a limited warranty covering manufacturing defects and offers a straightforward replacement process for tools that fail under normal operating conditions.
