Hertel 83246280 Carbide Die Drill Bit 0.0995 in 140 Deg

Product Description

The HERTEL 83246280 is a solid carbide die drill bit designed for precision drilling in hard and abrasive workpiece materials. Built from C2-grade carbide with a bright finish, this straight-flute drill produces clean, accurate holes in demanding applications. It measures 0.0995 inches in diameter with a 140-degree notched point and features a web-thinned design to reduce thrust and improve penetration. With a diameter tolerance of +0.0000 to -0.0005 inches, this bit holds tight dimensional accuracy. Right-hand cutting direction and 2-flute geometry make it suitable for machinists, tool-and-die shops, and precision fabrication operations.

This drill bit is suited for use in tool-and-die work, precision machining, and production drilling environments where close tolerances are required. It is rated for use in chrome alloy, heat-treated alloy, nickel alloy, stainless steel, carbon steel, and titanium alloy workpieces. The wire-gauge sizing corresponds to number 39, making it a common selection for tapping prep and die-making operations in both job shops and production facilities.

Key Features

• Solid carbide C2-grade construction for high hardness and wear resistance
• 140-degree notched point reduces walking and improves hole entry on hard materials
• Web-thinned design lowers axial thrust for cleaner drilling in tough alloys
• Bright finish with diameter tolerance held to +0.0000 to -0.0005 inches
• Straight-flute geometry suited to die drilling and precision hole work
• Right-hand cutting, 2-flute configuration for standard CNC and manual spindle use

Compatibility

Designed for precision drilling in chrome alloy, heat-treated alloy, nickel alloy, stainless steel, carbon steel, and titanium alloy workpieces. Corresponds to wire gauge size number 39.

Installation Notes

This bit is installed and operated by machinists or tool-and-die professionals using drill presses, CNC machining centers, or manual mills. Secure the shank firmly in a collet or drill chuck rated for the 0.0995-inch shank diameter before operation. Ensure the spindle is fully stopped before changing tooling. Use appropriate cutting fluid or coolant compatible with the workpiece material to extend tool life, as this bit does not feature through-coolant capability.
