Hertel 83246538 Solid Carbide Drill Bit 0.1820 in Wire 14

Product Description

The HERTEL 83246538 is a straight-flute, solid carbide drill bit designed for precision drilling in hard and exotic metals. Built from C2-grade carbide with a bright finish, it runs a 0.1820-inch diameter and a 140-degree notched point angle. The web-thinned geometry reduces thrust force at entry and improves chip clearing. This bit is suited for machinists, tool-and-die technicians, and production drilling operations where dimensional accuracy and tool life in tough alloys are the priority. It cuts right-hand and carries a tight diameter tolerance of plus 0.0000 to minus 0.0005 inches, making it appropriate for close-tolerance hole work.

This drill bit is rated for use in a broad range of ferrous and exotic workpiece materials including steel, stainless steel, heat-treated alloy, chrome alloy, nickel alloy, and titanium alloy. It is a practical choice for aerospace, defense, medical device, and general precision machining environments where material hardness and work-hardening tendencies demand carbide tooling over high-speed steel alternatives. The straight-flute design suits short-chipping materials where flute geometry needs to evacuate chips efficiently without packing.

Key Features

• Solid C2-grade carbide construction for extended tool life in hard and abrasive alloys
• 140-degree notched point angle reduces walking and improves entry accuracy
• Web-thinned design lowers drilling thrust and improves chip evacuation
• Bright finish, no coating, suitable for applications where coating adhesion or contamination is a concern
• Tight diameter tolerance of plus 0.0000 to minus 0.0005 inches for close-tolerance hole production
• Right-hand cutting, 2-flute straight configuration for short-chipping workpiece materials

Compatibility

Designed for use in hard and exotic metals including steel, stainless steel, heat-treated alloy, chrome alloy, nickel alloy, and titanium alloy. Suitable for CNC machining centers, drill presses, and manual machines equipped with appropriate collet or chuck systems that accept a 0.1820-inch shank diameter.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists familiar with carbide tooling requirements. Carbide is brittle — avoid side loading, interrupted cuts without proper setup, or excessive runout in the spindle or chuck, as these conditions can cause tip fracture. Secure the bit in a precision collet or drill chuck rated for the shank diameter before use. Follow applicable shop safety standards and machine manufacturer guidelines for RPM and feed rate selection when drilling the target workpiece material.
