Hertel 83246488 Solid Carbide Die Drill Bit 0.1660 in

Product Description

The HERTEL 83246488 is a solid carbide straight-flute die drill bit designed for precision drilling in hard and exotic metals. Ground to a 0.1660-inch diameter with a 140-degree notched point, it delivers accurate entry and clean hole geometry in materials that defeat standard high-speed steel tooling. The C2 carbide grade provides the hardness and wear resistance needed for consistent performance across production runs. A bright finish is applied without any coating that could alter dimensional tolerance. Two right-hand flutes and a web-thinned construction reduce thrust and improve chip evacuation during die and tool room work.

This bit is suited for machining operations in tool rooms, die shops, and precision manufacturing environments. It handles chrome alloy, heat-treated alloy, nickel alloy, stainless steel, carbon steel, and titanium alloy workpieces. The straight-flute geometry makes it appropriate for short-hole drilling and spot applications where standard spiral-flute bits may deflect. No coolant-through capability is present, so external cutting fluid or mist coolant is recommended when drilling heat-sensitive alloys. It is packaged and sold individually.

Key Features

• Solid C2 carbide construction for high wear resistance in hard metals
• 140-degree notched point reduces thrust and improves self-centering on hard surfaces
• Web-thinned design lowers cutting resistance and aids chip evacuation
• Bright finish preserves dimensional accuracy with tolerance of +0.0000 to -0.0005 inches
• Straight-flute configuration suited for short-hole and die-work drilling
• Right-hand cutting direction compatible with standard CNC and manual drill spindles

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide die drill bit for precision machining operations requiring a No. 19 wire size, 0.1660-inch diameter straight-flute drill in tool room and die shop applications.

Installation Notes

Installation and use should be performed by a qualified machinist or tool room technician. Secure the bit in a properly sized collet or drill chuck rated for carbide tooling before operation. Power down and lock out the machine before changing or inspecting bits. Avoid side-loading or using this bit for anything other than axial drilling, as carbide is brittle and susceptible to chipping under lateral stress.
