Cleveland C46169 Countersink 5/8 in 82 Degree 3 Flute Hss

Product Description

The CLEVELAND C46169 is a single-end countersink designed for creating conical seat profiles in metal workpieces ahead of flat-head fastener installation. Built from high speed steel with an oxide finish, it features a 5/8 inch head diameter and an 82-degree included angle suited to standard flat-head screw geometry. The 3-flute design balances material removal rate with surface finish quality. The straight-cylindrical shank measures 3/8 inch in diameter, making it compatible with standard drill press and hand-drill chuck configurations. A licensed machinist, tool and die technician, or maintenance mechanic typically selects this tool for production or maintenance drilling operations.

The C46169 is used in ferrous metalworking applications including carbon steel and cast iron workpieces. It is appropriate for both production-line countersinking and field maintenance scenarios where a clean, consistent seat angle is required prior to flush fastener installation. The right-hand cutting direction and straight shank make it straightforward to chuck into standard drilling equipment without adapters. Its 2.25 inch overall length provides enough reach for most sheet metal and light structural work without excessive overhang.

Key Features

• 3-flute configuration for balanced chip evacuation and finish quality
• High speed steel construction with oxide coating for wear resistance
• 3/8 inch straight-cylindrical shank fits standard drill chucks without adapters
• Rated for carbon steel and cast iron material applications
• Single-end design with no pilot for use with pre-drilled clearance holes

Compatibility

Designed as an OEM-style countersink for use in carbon steel and cast iron drilling and countersinking operations. No specific machine or system compatibility was stated in the product data.

Installation Notes

Installation and use should be performed by a qualified machinist or maintenance technician familiar with metalworking drill press or hand-drill operation. Always secure the workpiece firmly before engaging the cutter, and power down the drilling equipment completely before changing tooling. Use appropriate cutting fluid when countersinking ferrous materials to extend tool life and improve finish quality. Do not exceed the recommended RPM range for the workpiece material and tool diameter.
