Cleveland C46185 Countersink 1 in 120 Degree 3 Flute Hss

Product Description

The CLEVELAND C46185 is a single-end, straight-shank countersink designed for deburring and seat preparation in metalworking applications. Manufactured from high speed steel with an oxide finish, it cuts a 120-degree included angle at 1 inch head diameter. The three-flute geometry balances chip evacuation with surface finish quality, making it well suited for production and maintenance work in carbon steel and cast iron. A right-hand cutting direction and straight cylindrical shank provide straightforward setup in standard drill press or CNC spindles. No pilot is included, and the tool is offered as a head-and-shank unit rather than a head-only style.

This countersink is intended for use on carbon steel and cast iron workpieces in industrial, maintenance, and fabrication environments. Typical applications include chamfering drilled holes for fastener seating, deburring hole edges, and preparing countersunk screw seats. The 0.5 inch shank diameter fits standard collets, drill chucks, and quick-change tooling systems commonly found in machine shops, maintenance departments, and metalworking trade environments. It is sold as a single unit.

Key Features

• 1 inch head diameter with 120-degree included angle for standard countersunk fastener geometry
• Three-flute design promotes smooth cutting action and efficient chip removal
• High speed steel construction for durability in carbon steel and cast iron applications
• Oxide coating provides corrosion resistance and reduces surface friction during cutting
• Straight cylindrical shank at 0.5 inch diameter fits common collets and drill chucks
• Single-end, no-pilot design for direct chuck mounting without additional components

Compatibility

Rated for use in carbon steel and cast iron material applications. Fits standard 0.5 inch straight-shank toolholders, collets, and drill chucks used in drill presses, milling machines, and CNC machining centers.

Installation Notes

Installation and use should be performed by qualified machinists or metalworking tradespeople. Secure the shank fully in the toolholder and verify runout before cutting. Power down and lock out the machine spindle before changing or inspecting tooling. Do not exceed the recommended speed-and-feed parameters for the workpiece material and tool diameter.
