Cleveland C46130 Countersink 1 in 60 Deg Hss Right Hand

Product Description

The CLEVELAND C46130 is a single-flute, high speed steel countersink designed for producing clean, chamfered seating surfaces in metalworking applications. It features a 1-inch head diameter and a 60-degree included angle, making it well suited for standard fastener seating, deburring, and chamfering operations on carbon steel and cast iron workpieces. The straight cylindrical shank measures 0.5 inches in diameter for secure chuck holding, and an oxide coating provides basic corrosion resistance and reduced friction during cutting. This tool is right-hand cut and is installed and operated by machinists, tool and die workers, and maintenance technicians using standard drill presses or hand-held drilling equipment.

The C46130 is intended for countersinking operations on carbon steel and cast iron in production and maintenance environments. Its single-flute geometry promotes smooth chip evacuation and reduces chatter in materials that can work-harden or produce stringy chips. The 60-degree included angle is a common specification for metric and inch fastener head seating, deburring through-holes, and chamfering hole entries prior to assembly. This countersink is a single-end tool with no pilot and no integrated countersink head-only configuration, meaning it is used as a complete unit in a standard drill chuck or collet holder.

Key Features

• 1-inch head diameter with 60-degree included angle for standard fastener seating
• Single-flute design promotes smooth chip flow and reduced chatter
• High speed steel construction for durability across carbon steel and cast iron
• Oxide finish provides corrosion resistance and friction reduction
• 0.5-inch straight cylindrical shank fits standard drill chucks and collet holders
• Right-hand cut geometry for use with conventional clockwise-rotation drilling equipment

Compatibility

Designed for countersinking operations in carbon steel and cast iron. Fits any standard drill press, milling machine, or hand drill equipped with a chuck or collet sized for a 0.5-inch straight cylindrical shank.

Installation Notes

This countersink is installed by machinists or maintenance technicians in a drill press, milling machine, or hand-held drill. Power down and lock out the machine before inserting or removing the tool from the chuck or collet. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Secure the workpiece firmly before beginning the countersinking operation to prevent movement and tool damage.
