Hertel 19193 Countersink 1-1/4 in Hss 1 Flute

Product Description

The HERTEL 19193 is a single-flute countersink designed for producing clean, accurately angled seat profiles in metal and other rigid materials. The tool features a 1-1/4 inch head diameter, a 100-degree included angle, and a 1/2 inch straight-cylindrical shank. Constructed from high speed steel, it delivers consistent cutting performance across a range of ferrous and non-ferrous workpiece materials. This countersink is suited to production and maintenance machining environments where a precise countersink geometry is required for fastener seating, deburring, or spot-facing operations. Machinists and tool-and-die technicians are the typical end users.

This countersink is appropriate for use in both manual and CNC machining setups where a 1/2 inch straight shank is compatible with the spindle or chuck in use. The 100-degree included angle accommodates certain aerospace and specialty fastener head geometries that fall outside the more common 82-degree or 90-degree standards. It is well suited to light-production runs and repair work on machine components requiring consistent fastener flush-mount conditions. The single-flute design reduces chatter and promotes smooth cutting in applications where finish quality in the countersink seat is a priority.

Key Features

• 1-1/4 inch head diameter provides a large seating area suitable for larger fastener heads
• 100-degree included angle for specialty fastener head geometries
• Single-flute design minimizes chatter and improves surface finish in the countersink seat
• High speed steel construction offers durability across ferrous and non-ferrous materials
• 1/2 inch straight-cylindrical shank fits standard drill chucks and collet holders

Compatibility

Designed as a standard straight-shank countersink for use in drill presses, milling machines, and CNC machining centers equipped with a 1/2 inch chuck or collet. No specific model or system compatibility data was provided by the manufacturer for this part number.

Installation Notes

This tool is installed and used by machinists and maintenance technicians in shop environments. Secure the 1/2 inch shank firmly in a properly sized chuck or collet before operation. Set spindle speed according to the workpiece material and tool diameter — consult published cutting speed tables for high speed steel tooling. Inspect the cutting edge for wear before each use and do not force the tool against the workpiece to avoid chipping the flute edge.
