Hertel 85704435 Jobber Drill Bit 9/64 Inch Hss Tin

Product Description

The HERTEL 85704435 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastics. Built from high speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction compared to uncoated HSS. The bit measures 9/64 inch (0.1406 inch decimal) in diameter with a 2-7/8 inch overall length and a 1-3/4 inch flute length. The 118-degree standard point angle suits a wide range of common materials and is the most widely stocked geometry in trade and industrial settings. A web-thinned, tapered web design reduces the thrust required to start and drive the cut.

This drill bit is suited for light-duty production drilling, maintenance and repair operations, and general fabrication work. The straight-cylindrical shank fits standard 3-jaw chucks on corded and cordless drills, drill presses, and hand-held power tools. Right-hand cut with a regular spiral flute promotes efficient chip evacuation during through-hole and blind-hole drilling in common shop and field applications. It is used by HVAC technicians, electricians, plumbers, and general tradespeople for everyday drilling tasks on the job site or in the shop.

Key Features

• High speed steel construction with TiN coating for extended wear resistance and lower cutting friction
• 118-degree standard point angle for broad material compatibility
• Web-thinned tapered web reduces bit walking and lowers required thrust
• Regular spiral flute with right-hand cut for efficient chip clearance
• Straight-cylindrical shank compatible with standard 3-jaw chucks
• 2-flute geometry balances cutting speed with hole quality

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard 3-jaw drill chuck accepting a 9/64 inch straight-cylindrical shank.

Installation Notes

Installation is performed by licensed tradespeople or qualified operators using a properly rated drill press or handheld power tool. Secure the shank fully in the chuck and verify the bit runs true before cutting. Always wear appropriate eye protection and secure the workpiece before drilling. Replace the bit if the cutting edge shows signs of chipping, glazing, or excessive heat discoloration.
