Hertel 85703924 Jobber Drill Bit Size 15 Hss 118 Degree

Product Description

The HERTEL 85703924 is a jobber-length drill bit sized to wire gauge number 15, with a decimal diameter of 0.1800 inches. Built from high speed steel with a bright uncoated finish, it is designed for general-purpose drilling in metal, wood, and plastic. The standard 118-degree split point geometry with web thinning reduces walking and entry force. A regular spiral flute pattern with tapered web configuration promotes chip evacuation. This bit is a staple in tool kits for machinists, pipefitters, electricians, and maintenance technicians who need a reliable, everyday jobber drill in a smaller wire-gauge size.

The 85703924 is suited for bench-drill, hand-drill, and drill-press applications in light manufacturing, mechanical maintenance, MRO shops, and field service work. Its straight-cylindrical shank fits standard three-jaw chucks without adapters, making it compatible with the widest range of portable and stationary drilling equipment. The 0.1800-inch diameter falls in the 0.1500 to 0.2000 inch size range, covering common pilot-hole and clearance-hole tasks in trade and shop environments.

Key Features

• Wire gauge size 15 with 0.1800-inch decimal diameter for precise sizing
• High speed steel construction for durability across a broad range of workpiece materials
• 118-degree standard point angle with web thinning to reduce thrust and prevent walking
• Two-flute regular spiral design promotes consistent chip clearance
• Straight-cylindrical shank fits standard three-jaw chucks directly
• Bright uncoated finish allows easy visual inspection for wear

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard three-jaw chuck accepting a 0.1800-inch straight-cylindrical shank, suitable for bench drills, hand drills, and drill presses commonly used in trade and MRO applications.

Installation Notes

Installation is performed by machinists, maintenance technicians, or qualified tradespeople familiar with drilling equipment. Secure the straight-cylindrical shank fully in the chuck and tighten with the chuck key before operating. Ensure the workpiece is clamped or fixtured to prevent rotation. Use appropriate cutting fluid or coolant for metal drilling to extend bit life, and allow the bit to cool before handling after extended use.
