Cleveland C46133 Countersink 1 in Hss Right Hand Cut

Product Description

The CLEVELAND C46133 is a single-flute, high speed steel countersink designed for creating conical seat recesses in metal workpieces. It features a 1 inch head diameter and a 100-degree included angle, which corresponds to a 50-degree centerline angle. The straight-cylindrical shank measures 0.5 inches in diameter, providing solid tool holding in standard drill chucks and collet holders. An oxide coating helps reduce friction and extend tool life during cutting operations. This countersink is suited for machinists and tooling technicians working in production or job-shop environments.

The C46133 is intended for countersinking operations in carbon steel and cast iron workpieces. Its single-flute geometry is well matched to applications where smooth surface finish in the countersink seat is the priority. The right-hand cut configuration is compatible with standard CNC machining centers, drill presses, and manual lathes. It does not include a pilot, so center location must be established prior to use. This tool is sold individually as a single unit.

Key Features

• 1 inch head diameter with 100-degree included angle for standard fastener seat geometry
• Single-flute design promotes clean, chatter-free cutting action
• High speed steel construction provides durability across carbon steel and cast iron applications
• Oxide coating reduces friction and improves tool longevity
• Straight-cylindrical 0.5 inch shank for broad tool holder compatibility
• Right-hand cut, no pilot included — center hole required before use

Compatibility

Designed for countersinking operations in carbon steel and cast iron. Compatible with standard drill presses, CNC machining centers, and manual lathes accepting a 0.5 inch straight-cylindrical shank.

Installation Notes

This countersink should be installed by a qualified machinist or tooling technician using appropriate tool holders rated for the shank diameter. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Because this tool does not include a pilot, a center drill or pre-drilled pilot hole must be in place before countersinking to prevent walking. Use appropriate cutting fluid for the workpiece material to maintain tool life and surface finish quality.
