Hertel 85707651 Jobber Drill Bit Wire 41 Hss Tin

Product Description

The HERTEL 85707651 is a jobber-length twist drill bit designed for general-purpose metal drilling applications. It is manufactured from high speed steel (HSS) with a titanium nitride (TiN) coating that increases surface hardness and extends tool life in repetitive drilling operations. The bit is wire gauge size 41, corresponding to a decimal diameter of 0.0960 inches. Overall length is 2-3/8 inches with a flute length of 1-3/8 inches. The 118-degree standard point angle is suited for drilling mild steel, aluminum, brass, and similar materials. This bit is installed by machinists, maintenance technicians, and general fabrication trades.

This drill bit is used in hand-held electric drills, drill presses, and CNC drilling operations where a wire gauge 41 hole is required. Its straight-cylindrical shank seats in standard three-jaw drill chucks without modification. The general-purpose grade and 0.0500 to 0.1000 inch size range classification make it a common selection for production drilling, sheet metal work, and light mechanical assembly. The right-hand spiral flute configuration clears chips away from the cutting edge during standard forward-rotation drilling.

Key Features

• Wire size 41 — decimal diameter of 0.0960 inches
• TiN coating for increased surface hardness and extended tool life
• 118-degree standard point angle for general-purpose drilling
• Right-hand cut with regular spiral and 2-flute configuration for efficient chip evacuation
• Web-thinned, tapered web design reduces thrust required at entry
• Straight-cylindrical shank fits standard drill chucks

Compatibility

Designed as a general-purpose jobber-length drill bit for use in any standard drill chuck accepting a 0.0960-inch straight shank, including hand drills, drill presses, and CNC equipment.

Installation Notes

Secure the shank fully in the chuck and verify concentricity before drilling. Power down the machine and isolate the circuit before changing bits. Use cutting fluid when drilling ferrous metals to preserve the TiN coating and reduce heat buildup. Coolant-through operation is not supported by this bit.
