Hertel H-81185020600 Combo Drill Countersink Hss

Product Description

The HERTEL H-81185020600 is a combination drill and countersink designed for simultaneous drilling and countersinking in a single pass. Built from high-speed steel with a bright uncoated finish, this tool handles trade size 2 work with a 3/16 inch body diameter and a 5/64 inch drill point diameter. The 118-degree drill point angle and 60-degree included angle on the countersink are standard geometry for general metalworking and fabrication applications. At 6 inches overall length, it qualifies as a long-length tool. Machinists, tool and die workers, and general fabricators use this type of tool to prepare countersunk fastener seats without changing tooling mid-operation.

This combo drill countersink is suited for use in drill presses, milling machines, and CNC machining centers where countersinking of metal workpieces is required. The plain cutting edge style and double end type make it a versatile option for general shop use. It is not aircraft-style and is not tapered, making it appropriate for standard 60-degree countersink applications in production or maintenance environments. The long-length design provides additional reach for deeper work setups.

Key Features

• High-speed steel construction for durability across general metalworking applications
• Bright uncoated finish suitable for use with cutting fluids
• 118-degree drill point angle for standard metal drilling geometry
• 60-degree included angle for countersinking standard flat-head fastener seats
• Double end type extends tool life by providing two usable ends
• Long-length design at 6 inches overall for added reach in deep setups

Compatibility

Designed as an OEM-style replacement or standard tooling option for drill presses, milling machines, and CNC machining centers requiring a size 2 combo drill countersink with a 60-degree included angle.

Installation Notes

Install and remove this tool only while the machine is fully powered down and the spindle has come to a complete stop. Use an appropriate collet or drill chuck rated for the 3/16 inch body diameter. Apply cutting fluid when working with ferrous metals to extend tool life and improve finish quality. Inspect the cutting edges before each use and do not use a tool with visible chipping or wear on the drill point.
