Harvey Tool 17940 Combo Drill Countersink No. 2 3/16 Inch

Product Description

The HARVEY TOOL 17940 is a solid carbide combined drill and countersink designed for precise center drilling and countersinking in a single operation. Built to trade size No. 2, it features a 3/16 inch body diameter and a 5/64 inch drill point diameter with a 118-degree drill point angle. The double-end design provides two usable cutting ends, extending tool life. At 2 inches overall length, this right-hand cut tool suits bench-top and CNC drilling applications where accuracy and repeatability matter. It is used by machinists, tool-and-die makers, and precision fabricators working in metal fabrication and machine shops.

This combined drill and countersink is suited for center drilling workpieces prior to turning between centers on a lathe, as well as for producing 90-degree countersunk entries for flat-head fasteners. The bright, uncoated solid carbide construction makes it appropriate for use on ferrous and non-ferrous metals, including steel, aluminum, and brass, where a sharp cutting edge and dimensional consistency are required. The double-end configuration is common in production environments where minimizing tool changeover time is a priority.

Key Features

• Solid carbide construction for rigidity and extended tool life compared to high-speed steel alternatives
• Double-end design provides two cutting ends per tool
• 118-degree drill point angle for standard center drilling and countersinking
• 90-degree included angle for flat-head fastener countersinking
• Bright, uncoated finish suitable for general-purpose metal cutting
• Right-hand cut, plain cutting edge style for standard machining setups

Compatibility

Designed as an OEM-style replacement or direct-use combined drill and countersink for trade size No. 2 applications in standard machining and fabrication setups.

Installation Notes

This tool is installed by machinists and CNC operators into collet chucks, drill chucks, or tool holders appropriate for a 3/16 inch shank diameter. Ensure the machine spindle is fully stopped before inserting or removing the tool. Use appropriate cutting fluid or coolant for the workpiece material to preserve edge life. Inspect both cutting ends before use and replace the tool if chipping or excessive wear is observed on the active end.
