Harvey Tool 11030 Combo Drill Countersink 1/8 in Solid Carbide

Product Description

The HARVEY TOOL 11030 is a solid carbide combination drill and countersink designed to drill a pilot hole and countersink in a single pass. Built to trade size No. 1, it features a 1/8 inch body diameter, a 3/64 inch point diameter, and a 118-degree drill point angle with a 60-degree included countersink angle. The bright, uncoated finish is suited to a wide range of materials where coating is not required. At 1-1/2 inches overall length, this is a compact, rigid tool appropriate for precision work in CNC machining, manual mills, and drill press setups. Machinists, toolmakers, and fabricators use this style of combined tool to reduce setups and maintain hole-to-countersink concentricity.

This tool is used in metalworking and fabrication environments where pilot drilling and countersinking must be performed in a single operation. The double-end configuration extends usable tool life by providing two cutting ends. Right-hand cutting direction makes it compatible with standard spindle rotation on the vast majority of machine tools. Typical applications include deburring, chamfering, and preparing holes for flat-head fasteners in ferrous and non-ferrous metals, plastics, and composites.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• Combined drill and countersink geometry completes pilot hole and chamfer in one pass
• Double-end design provides two usable cutting ends to extend tool life
• 118-degree drill point angle suits a broad range of workpiece materials
• 60-degree included angle for standard countersink geometry
• Bright, uncoated finish suitable for use without coolant-specific coating requirements

Compatibility

Designed as an OEM-style replacement or direct-use combined drill and countersink for standard toolholders accepting 1/8 inch shank diameters on CNC machining centers, manual mills, and drill presses.

Installation Notes

This tool is installed by machinists and toolroom technicians in standard collet or drill chuck toolholders. Ensure the machine spindle is fully stopped and power is locked out before inserting or removing the tool. Secure the tool to the full recommended collet grip depth to prevent pullout at operating speeds. Do not exceed the machine spindle speed rating or use excessive feed pressure, as solid carbide is rigid but brittle under lateral loading.
