Hertel 85707453 Jobber Drill Bit Wire 23 Hss Tin 118 Deg

Product Description

The HERTEL 85707453 is a jobber-length drill bit designed for general-purpose metal drilling in production and maintenance environments. Manufactured from high-speed steel (HSS) with a titanium nitride (TiN) coating, it runs at higher surface speeds than uncoated HSS and resists wear during repeat-hole operations. The bit measures 3.125 inches overall, carries a 118-degree standard point angle, and uses a right-hand spiral flute to clear chips efficiently. Wire gauge size 23 corresponds to a decimal diameter of 0.154 inches. The straight-cylindrical shank seats directly in standard three-jaw chucks on drill presses, hand drills, and CNC equipment. Licensed machinists, maintenance technicians, and tool-room professionals are the primary users.

This bit suits drilling through mild steel, aluminum, brass, plastics, and similar materials in light-to-medium duty applications. The web-thinned, tapered web configuration reduces thrust requirements at the point, making it practical for hand-held drilling as well as machine setups. With a 2-inch flute length, the bit handles material stock up to its usable flute depth before requiring withdrawal for chip clearing. It ships individually and is ordered in multiples of 12, making it suitable for stocking tool cribs or job boxes where wire-gauge bits are consumed regularly.

Key Features

• HSS construction with TiN coating for extended tool life compared to uncoated HSS bits
• 118-degree standard point angle with web thinning reduces entry thrust on thin-gauge and sheet material
• 0.154-inch diameter (Wire Size 23) with straight-cylindrical shank fits standard drill chucks without adapters
• Right-hand, regular spiral flute with 2-inch flute length promotes consistent chip evacuation
• Tapered web configuration improves self-centering at the drill point
• General-purpose grade covers a broad range of ferrous and non-ferrous workpiece materials

Compatibility

Designed as a general-purpose jobber-length replacement or stocking bit for any drill press, hand drill, or CNC spindle equipped with a chuck that accepts a 0.154-inch straight-cylindrical shank.

Installation Notes

Secure the shank fully in the chuck jaws and verify runout before drilling. Always wear appropriate eye protection and ensure the workpiece is firmly clamped or fixtured before applying feed pressure. For TiN-coated HSS bits, use cutting fluid or coolant on ferrous materials when drill press feeds allow, as dry cutting at sustained high speeds will shorten coating life. Inspect the bit for chipping or point damage before reuse, as a damaged 118-degree point increases thrust and reduces hole quality.
