Cleveland C46200 Countersink 0.25 in 90 Degree 4 Flute Hss

Product Description

The CLEVELAND C46200 is a single-end, straight-shank countersink designed for creating conical seat profiles in metal workpieces. It features a 0.25-inch head diameter, a 90-degree included angle (45-degree centerline angle), and four flutes ground from high speed steel with an oxide finish. The right-hand cutting direction and straight-cylindrical shank make it a direct fit for standard drill chucks and collet holders. Licensed machinists, tool-and-die workers, and maintenance technicians reach for this tool when countersinking for flat-head fasteners in alloy tool steel and cast iron applications.

The C46200 is suited for countersinking operations in both production and maintenance environments. Its 0.1875-inch (3/16-inch) shank and 1.438-inch overall length make it compact enough for close-tolerance work and benchtop drill press setups. The 90-degree angle matches the seating profile required by most standard flat-head machine screws and bolts. It does not include a pilot and is not a head-only style, so it cuts the full countersink profile in a single pass through the workpiece.

Key Features

• 0.25-inch head diameter with a 90-degree included angle for standard flat-head fastener seating
• 4-flute design improves chip clearance and surface finish in ferrous materials
• High speed steel construction with oxide coating for wear resistance and reduced friction
• Right-hand cut, straight-cylindrical shank fits standard drill chucks and collet systems
• Single-end, no-pilot design delivers a clean countersink in one pass
• Rated for use in alloy tool steel and cast iron

Compatibility

Designed for countersinking operations in alloy tool steel and cast iron. Fits standard drill chucks and collet holders accepting a 3/16-inch straight-cylindrical shank.

Installation Notes

Installation is performed by machinists or maintenance technicians using a drill press, milling machine, or hand drill with appropriate chuck. Secure the workpiece firmly before operation and use cutting fluid when working in tool steel or cast iron to extend tool life. Inspect the cutting edges before each use and replace if chipping or excessive wear is observed. Follow applicable shop safety procedures and machine guarding requirements during all drilling and countersinking operations.
