Hertel 83246199 Die Drill Bit 0.0760 in Wire 48 Carbide

Product Description

The HERTEL 83246199 is a straight-flute die drill bit designed for precision drilling in hard and difficult-to-machine materials. Built from solid carbide grade C2 with a bright finish, this bit measures 0.0760 inches in diameter and corresponds to wire gauge size 48. The 140-degree notched point geometry, combined with web thinning, reduces thrust and improves chip clearance at entry. With a right-hand cutting direction and two flutes, this drill suits applications where tight tolerances and clean hole geometry are critical. Diameter tolerance is held to +0.0000 to -0.0005 inches, making it appropriate for die work and precision tooling operations.

This drill bit is engineered for use in metals including chrome alloy, heat-treated alloy, nickel alloy, stainless steel, carbon steel, and titanium alloy. It is a strong choice for tool and die shops, aerospace component machining, and precision fabrication work where small-diameter, high-accuracy holes are required. The straight-flute design makes it particularly effective in applications where chip evacuation from deep holes must be controlled carefully.

Key Features

• Solid carbide C2 grade construction for hardness and wear resistance in alloy and stainless materials
• 140-degree notched point for reduced entry thrust and accurate self-centering
• Web-thinned geometry to lower cutting force and improve chip flow
• Diameter tolerance of +0.0000 to -0.0005 inches for precision fitment
• Right-hand, straight-flute design suited for die drilling and controlled-feed operations
• Bright finish with no coolant-through requirement, compatible with external cutting fluid application

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for straight-flute die drill applications requiring a 0.0760-inch diameter, wire gauge size 48 solid carbide bit in chrome alloy, heat-treated alloy, nickel alloy, stainless steel, steel, and titanium alloy workpieces.

Installation Notes

Installation and use should be performed by a qualified machinist or tool and die technician familiar with small-diameter carbide tooling. Secure the shank in a precision collet or drill chuck rated for the spindle speed required by the workpiece material. Carbide tooling is brittle and susceptible to chipping under side loads or interrupted cuts — avoid flexing or lateral force during operation. Apply cutting fluid externally as appropriate for the workpiece material to extend tool life and maintain hole quality.
