Cleveland C52773 Combo Drill Countersink Size 2 Solid Carbide

Product Description

The CLEVELAND C52773 is a solid carbide combination drill and countersink designed for precision drilling and countersinking in a single pass. Built to Series 1798 standards, this size 2 tool features a 5/64-inch drill point diameter and a 60-degree included angle, making it well-suited for spotting, centering, and countersinking holes in ferrous and non-ferrous metals. The bright, uncoated finish keeps cutting edges sharp and visible during use. At 1-7/8 inches overall length and right-hand cut geometry, it fits standard drill chucks and is appropriate for bench drill presses, CNC machining centers, and manual lathes. Machinists and tool-and-die technicians are the primary users of this style of combination tool.

This combo drill countersink is intended for use on alloy steel, aluminum, carbon steel, and cast iron workpieces. The double-end configuration maximizes tool life by providing two usable cutting ends before the tool is retired. With a plain cutting edge style and non-tapered, non-aircraft body profile, this is a standard industrial center drill suitable for production and job-shop environments where consistent countersink geometry is required. It is not designed for composite, hardened, or exotic alloy materials without additional verification of tool parameters.

Key Features

• Solid carbide construction provides rigidity and wear resistance during high-speed drilling and countersinking
• 60-degree included angle produces standard countersink geometry for center drilling and screw-seat preparation
• Double-end design extends usable tool life by offering two cutting ends
• Right-hand cut with plain cutting edge style for conventional feed and speed setups
• Bright, uncoated finish suited for use with cutting fluids on steel and aluminum
• Size 2 trade size with 5/64-inch drill point fits standard center drill applications

Compatibility

Compatible with alloy steel, aluminum, carbon steel, and cast iron workpieces as specified by the manufacturer. Designed as a standard Series 1798 combination drill and countersink for industrial machining applications.

Installation Notes

This tool is installed in a drill chuck, collet, or lathe tailstock appropriate for the body diameter. Ensure the machine spindle is fully stopped before changing or inspecting the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality. Follow shop safety protocols and applicable OSHA machining guidelines when operating drill presses or lathes.
