Hertel 336-002070 Carbide Countersink 3/16 in 6 Flute

Product Description

The HERTEL 336-002070 is a solid carbide countersink designed for creating chamfered seat profiles in drilled holes. It features a 90-degree included angle and a 45-degree centerline angle, with six flutes ground for smooth cutting action and chip evacuation. The straight cylindrical shank measures 3/16 inches in diameter and matches the 3/16-inch head diameter. The bright, uncoated carbide construction provides hardness and edge retention for use in demanding materials. This countersink is intended for machinists, tool and die professionals, and fabricators who need consistent chamfer geometry in production or job-shop environments.

The 336-002070 is suited for countersinking in alloy steel, cast iron, and glass-reinforced plastic. Its single-end, no-pilot design is typical for precision machine tool applications where the operator controls depth and alignment through the machine setup. The six-flute geometry reduces chatter and produces a cleaner finish compared to fewer-flute alternatives, making it appropriate for light to medium material removal in metalworking and composite machining operations.

Key Features

• 3/16-inch head diameter with matching 3/16-inch straight cylindrical shank
• 90-degree included angle and 45-degree centerline angle for standard countersink profiles
• Six flutes for reduced chatter and improved surface finish
• Solid carbide construction, bright uncoated finish for general-purpose use
• Right-hand cut, single-end design with no pilot included
• Rated for alloy steel, cast iron, and glass-reinforced plastic

Compatibility

Designed as an OEM-style replacement or direct tooling selection for standard straight-shank countersink applications in alloy steel, cast iron, and glass-reinforced plastic machining setups.

Installation Notes

Installation is performed by machinists or toolroom professionals using a drill press, milling machine, or CNC machining center with an appropriate straight-shank collet or tool holder sized for 3/16-inch shanks. Secure the shank fully in the holder before operation and verify runout before cutting. Always follow applicable machine guarding and PPE requirements when working with rotating carbide tooling. Inspect the cutting edges before each use and remove the tool from service if chipping or wear is detected.
