Hertel 331-002050 Countersink 3/16 in 60 Degree 1 Flute

Product Description

The HERTEL 331-002050 is a single-flute countersink designed for creating clean, conical seat recesses in workpiece surfaces. It features a 3/16-inch head diameter, a 60-degree included angle, and a matching 3/16-inch straight cylindrical shank. The bright, uncoated alloy steel construction delivers solid cutting performance across a range of compatible materials. With a right-hand cutting direction and single-end configuration, this countersink suits precision deburring and fastener seat preparation tasks in production and maintenance environments. No pilot is included, and the tool ships ready for use with standard collet or drill chuck setups.

This countersink is suited for shop and field use where controlled countersink depth and clean entry angles are required. It is intended for machining operations involving alloy steel, cast iron, and glass-reinforced plastic workpieces. The straight cylindrical shank allows direct chucking in most standard drill presses, CNC machines, and hand-held power drills equipped with appropriate collets or chucks. It is commonly used by machinists, tool-and-die workers, and maintenance technicians for deburring holes and preparing seating surfaces for flat-head fasteners.

Key Features

• 3/16-inch head diameter with matching 3/16-inch straight cylindrical shank
• 60-degree included angle and 30-degree centerline angle for standard countersink geometry
• Single-flute design for controlled material removal
• Right-hand cutting direction for use with conventional drill rotation
• Bright, uncoated finish — no coating buildup to affect dimensional tolerances
• Rated for use in alloy steel, cast iron, and glass-reinforced plastic

Compatibility

Designed for countersinking operations in alloy steel, cast iron, and glass-reinforced plastic workpieces. The straight cylindrical shank fits standard drill chucks and collet holders accepting 3/16-inch shank tooling.

Installation Notes

This tool is installed by machinists or maintenance technicians using a drill press, CNC spindle, or hand-held power drill with a compatible chuck or collet. Secure the shank firmly before operation and verify spindle speed is appropriate for the workpiece material and tool diameter. Always power down and lock out the machine before changing tooling. Do not exceed the tool's rated material applications to avoid premature wear or breakage.
