Hertel 83246520 Straight-flute Die Drill Bit 0.1800 in

Product Description

The HERTEL 83246520 is a straight-flute die drill bit designed for precision drilling in hard and exotic metals. Built from C2-grade solid carbide with a bright finish, this bit delivers consistent performance in demanding material removal applications. It measures 0.1800 inches in diameter, equivalent to a wire size 15, and features a 140-degree notched point with web thinning for clean entry and reduced thrust. The two-flute, right-hand cutting geometry suits high-precision production and tool-and-die work where tight tolerances and reliable chip evacuation are critical.

This drill bit is suited for metalworking applications involving chrome alloy, heat-treated alloy, nickel alloy, stainless steel, steel, and titanium alloy workpieces. It is a practical choice for tool-and-die shops, aerospace component manufacturers, precision machine shops, and industrial maintenance environments where hard materials are routinely drilled. The straight-flute design is particularly effective in brittle or hard materials where a standard spiral flute may cause chipping or deflection.

Key Features

• Solid carbide construction, C2 material grade, for extended tool life in hard metals
• 140-degree notched point reduces walking and improves hole entry accuracy
• Web-thinned design lowers cutting thrust and improves chip clearance
• Straight-flute geometry suited for drilling brittle and hard alloy materials
• Bright finish with no coating, maintaining precise dimensional tolerances
• Diameter tolerance held to +0.0000 to -0.0005 inches for precision fitment

Compatibility

Designed for use in hard and exotic metal workpieces including chrome alloy, heat-treated alloy, nickel alloy, stainless steel, steel, and titanium alloy. Fits standard drill chucks and collet systems accepting a 0.1800-inch shank diameter.

Installation Notes

This bit is installed by machinists and tool-and-die technicians using compatible drill presses, CNC machining centers, or hand-held drill motors with appropriate collet or chuck systems. Ensure the machine is fully stopped and isolated from power before changing tooling. Solid carbide is brittle and susceptible to breakage under side loading or improper feed rates — do not force or flex the bit during operation. Coolant-through is not supported on this bit; use an appropriate external cutting fluid for the workpiece material.
