Hertel 85707743 Jobber Drill Bit Wire 50 0.0700 in Hss Tin

Product Description

The HERTEL 85707743 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. It is sized to wire gauge number 50, with a decimal diameter of 0.0700 inches and an overall length of 2 inches. The bit is manufactured from high speed steel with a titanium nitride (TiN) coating that increases surface hardness and reduces friction for longer tool life. The standard 118-degree split point and web-thinned, tapered web geometry promote accurate starting and reduce walking on entry. This bit is a common choice for machinists, maintenance technicians, and fabricators working with close-tolerance hole requirements.

This drill bit suits general-purpose applications in job shop, production, and MRO environments where wire-gauge-sized holes are required. At 0.0700 inches, it covers small-diameter work such as tapping pilot holes, electrical knockout preparation, and light sheet metal fabrication. The 2-inch overall length and straight-cylindrical shank make it compatible with standard drill chucks on both bench-top drill presses and handheld power tools. Its right-hand spiral flute geometry clears chips efficiently during through-hole drilling in a wide range of workpiece materials.

Key Features

• Wire size number 50 with 0.0700-inch decimal diameter for close-tolerance small-hole work
• TiN coating improves surface hardness and extends cutting edge life over uncoated HSS
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust and accurate entry
• Right-hand cut with regular spiral and 2-flute geometry for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks without adapters
• 1-inch flute length accommodates typical depth requirements for this diameter range

Compatibility

Designed as a general-purpose jobber-length drill bit suitable for use in any standard drill chuck accepting a 0.0700-inch straight-cylindrical shank.

Installation Notes

This bit is installed and used by machinists, maintenance technicians, and general fabricators. Secure the straight shank fully in the drill chuck and tighten all jaws evenly before operation. Apply cutting fluid when drilling hardened steel or stainless to preserve the TiN coating and cutting edge. Inspect the point for chipping or wear before each use, as small-diameter bits are susceptible to breakage if run at incorrect feed rates or speeds.
