Hertel 18044 Countersink 1-1/2 in 60 Degree Hss 1 Flute

Product Description

The HERTEL 18044 is a single-flute countersink designed for producing clean, conical seat profiles in metal workpieces. With a 1-1/2 inch head diameter and a 60-degree included angle, it is built for applications that require precise angular seating — such as flat-head fastener recesses and deburring operations on drilled holes. The tool is constructed from high speed steel (HSS), which provides adequate hardness and wear resistance for general-purpose cutting in mild steel, aluminum, brass, and similar machinable metals. The 3/4 inch straight cylindrical shank mounts directly into standard drill chucks and machine tool holders. This countersink is a production-grade tool installed by machinists, toolroom technicians, and maintenance trades operating drill presses, mills, or CNC equipment.

This countersink is suited for manual and machine-fed applications in job shops, maintenance facilities, and light manufacturing environments. The single-flute geometry reduces chatter tendency on hand-held and lower-rigidity setups compared to multi-flute designs. The 60-degree included angle matches the seating geometry required by metric and unified flat-head machine screws commonly used in general fabrication and equipment assembly. It is intended for use in non-interrupted cuts on ferrous and non-ferrous base materials within standard cutting-speed parameters for HSS tooling.

Key Features

• 1-1/2 inch head diameter provides a wide countersink recess suitable for larger fastener heads and deburring wide-bore openings
• 60-degree included angle matches standard flat-head fastener seating geometry
• Single-flute design reduces vibration and chatter during operation
• High speed steel construction offers hardness and resharpening capability for general-purpose metal cutting
• 3/4 inch straight cylindrical shank is compatible with standard drill chucks and collet holders

Compatibility

Designed as a general-purpose countersink for use in standard drill chucks and collet-style tool holders accepting a 3/4 inch straight cylindrical shank. No specific machine models or replacement part numbers were provided by the manufacturer for this item.

Installation Notes

Installation is performed by machinists or maintenance technicians. Before mounting, confirm the machine spindle or chuck is fully de-energized and at rest. Secure the shank fully into the chuck or collet and verify runout before cutting. Follow established HSS cutting-speed guidelines for the workpiece material and apply appropriate cutting fluid to extend tool life and maintain surface finish quality.
