Hertel 16692048 Carbide Jobber Drill Bit 1/2 in Tin

Product Description

The HERTEL 16692048 is a solid carbide jobber-length drill bit designed for precision drilling in hard and abrasive materials. It carries a Titanium Nitride (TiN) coating that reduces friction and extends tool life in demanding applications. The 118-degree standard point angle provides a stable entry, while the web-thinned, tapered-web geometry reduces thrust requirements at the cutting edge. With a 1/2-inch diameter and a 4-3/4-inch overall length, this bit is sized for production and maintenance machining operations performed by machinists, tool-and-die technicians, and metalworking tradespeople.

This drill bit is suited for use in CNC machining centers, drill presses, and manual mills where solid carbide tooling is required for harder workpiece materials. The straight-cylindrical shank allows it to seat directly in standard chucks and collets without adapters. The two-flute spiral configuration with a regular spiral type promotes chip evacuation during through-hole and blind-hole drilling. Coolant-through capability is not supported on this bit, so surface or flood coolant should be used where heat management is a concern.

Key Features

• Solid carbide construction, Material Grade C2, for rigidity and wear resistance in hard materials
• Titanium Nitride (TiN) coating reduces friction and increases surface hardness of the cutting edge
• 118-degree standard point angle with web-thinned, tapered-web design for reduced thrust and clean entry
• Right-hand cut, two-flute regular spiral for efficient chip clearance
• Straight-cylindrical shank in 1/2-inch diameter seats in standard chucks and collets
• Series 450 jobber-length format with 3-inch flute length and maximum drilling depth of 4-3/8 inches

Compatibility

Designed as an OEM-style replacement and standard tooling option for metalworking operations requiring a 1/2-inch solid carbide jobber drill bit with a straight-cylindrical shank and TiN coating. Compatible with drill bit size range 0.5000 to 0.6500 decimal inch tolerance class applications.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tradespeople familiar with carbide tooling. Before mounting, power down and lock out the machine spindle per applicable safety procedures. Solid carbide is brittle compared to high-speed steel; avoid side-loading, interrupted cuts, or impact conditions that can cause chipping or fracture. Use appropriate flood or surface coolant since this bit does not support coolant-through delivery.
