The HERTEL 85704310 is a jobber length drill bit designed for general-purpose drilling in metal, wood, and plastic. It is sized to wire gauge 54 with a decimal diameter of 0.0550 inches and features a 118-degree standard point angle for straightforward entry into most common workpiece materials. The bit is manufactured from high speed steel with a bright, uncoated finish. At 1-7/8 inches overall length with a 7/8-inch flute length, it fits standard drill chucks and is suited for benchtop drill presses, hand drills, and CNC applications where a straight cylindrical shank is required. Licensed machinists, maintenance technicians, and fabricators are the primary users.
This bit is well suited for light drilling operations in metal fabrication shops, maintenance and repair environments, and production settings that require consistent small-diameter hole quality. The wire gauge 54 size is commonly used for pilot holes, tap preparation, and through-hole work on thin-gauge sheet metal and light structural stock. The right-hand spiral flute design clears chips efficiently during standard forward drilling. The tapered web configuration with web thinning improves point stability and reduces the force required to start the cut.
Designed as a general-purpose jobber length drill bit for use in standard drill chucks accepting straight cylindrical shanks in the 0.0500 to 0.1000 inch diameter range.
This bit is installed and replaced by machinists, tool and die technicians, and maintenance professionals. Secure the shank fully in the drill chuck and verify concentricity before engaging the workpiece. Use cutting fluid appropriate to the workpiece material when drilling metal to extend tool life and improve hole finish. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed, as a worn point on a small-diameter bit increases the risk of breakage.
