Harvey Tool 11060 Combo Drill Countersink Solid Carbide

Product Description

The HARVEY TOOL 11060 is a solid carbide combo drill countersink designed to drill a pilot hole and cut a countersink in a single pass. With a No. 4 trade size, a 5/16-inch body diameter, and a 118-degree drill point angle, this tool handles both operations without requiring a tool change. The 60-degree included angle and plain cutting edge style deliver clean, consistent results in production and job-site environments. The bright, uncoated finish suits general-purpose countersinking applications. At 2.5 inches overall length and 0.3 pounds, it is compact and easy to handle in a standard drill chuck or CNC setup.

This combo drill countersink is built for countersinking applications in metalworking and fabrication environments. The right-hand cut and double end type make it a practical choice for high-volume or repetitive fastener-prep work. It is suitable for use by machinists, metalworkers, and fabricators working with No. 4 fasteners where a clean countersink seat is required. The solid carbide construction provides the hardness and wear resistance needed for demanding materials and tight tolerances.

Key Features

• Single-pass combo tool: drills pilot hole and countersinks simultaneously
• Solid carbide construction for hardness and wear resistance
• 118-degree drill point angle with 1/8-inch point diameter
• 60-degree included angle for standard countersink seat geometry
• Right-hand cut with plain cutting edge style
• Double end type extends usable tool life
• Bright, uncoated finish — no coating buildup in tight clearances

Compatibility

Designed as an OEM-style replacement or direct-use combo drill countersink for No. 4 trade size fastener applications requiring a 5/16-inch body diameter and 60-degree countersink geometry.

Installation Notes

Install in a drill press, CNC machining center, or hand drill using a chuck sized for the 5/16-inch body diameter. Secure the workpiece firmly before operation. Use cutting fluid appropriate to the base material to preserve carbide edge life. Inspect the cutting edges before each use — carbide is brittle and can chip if the tool is dropped or mishandled.
