Hertel 85704567 Jobber Drill Bit 11/32 in Hss Tin

Product Description

The HERTEL 85704567 is a jobber-length twist drill bit designed for general-purpose metal drilling in shop and field applications. Manufactured from high speed steel with a titanium nitride (TiN) coating, it delivers improved wear resistance and longer tool life compared to uncoated HSS bits. The bit measures 11/32 inches (0.3438 inches decimal) in diameter with a 4-3/4 inch overall length and a 3-7/16 inch flute length. The 118-degree standard point angle suits a wide range of common materials. A right-hand, two-flute spiral configuration with a tapered web and web-thinned point reduces thrust and improves chip evacuation during drilling.

This bit fits standard jobber-length applications across metalworking, HVAC fabrication, plumbing rough-in, and electrical panel work where a precise 11/32-inch hole is required. The straight-cylindrical shank seats in standard 3-jaw drill chucks on corded or cordless drills and drill presses. It is suited for drilling mild steel, aluminum, copper, brass, and similar materials encountered in trade service work. Individual packaging makes it a practical single-replacement option for tool kits and service vans.

Key Features

• High speed steel construction with TiN coating for extended wear resistance
• 118-degree standard point angle for versatile use across common metals and alloys
• Web-thinned, tapered web design reduces drill thrust and improves hole entry
• Two-flute regular spiral configuration promotes efficient chip clearing
• Straight-cylindrical shank compatible with standard drill chucks
• No coolant-through requirement — suitable for dry drilling in field conditions

Compatibility

Designed as a general-purpose jobber-length drill bit for use in any standard 3-jaw drill chuck accepting an 11/32-inch straight-cylindrical shank, across drill presses, hand drills, and right-angle drills commonly used in HVAC, plumbing, and electrical trades.

Installation Notes

Install and remove drill bits only with the drill unpowered and the chuck fully released. Secure the shank firmly in the chuck before operation to prevent slippage and runout. Eye protection is required per standard shop safety practice. Avoid excessive feed pressure, which can overheat the cutting edge and reduce TiN coating effectiveness, particularly when drilling hardened or stainless steel.
