Hertel 95000409 Jobber Drill Bit 0.1406 in Hss 135 Deg

Product Description

The HERTEL 95000409 is a jobber-length drill bit designed for general-purpose holemaking in metal, wood, and similar materials. It measures 0.1406 inches (9/64 inch) in diameter with an overall length of 3.5 inches and a flute length of 1.75 inches. The bit is manufactured from high speed steel (HSS) with a bright, uncoated finish. The 135-degree split-point angle reduces walking on entry and requires less thrust than a standard 118-degree point. This is a two-flute, spiral-flute design with a regular helix. Machinists, maintenance technicians, HVAC installers, electricians, and plumbers commonly use jobber-length bits for layout drilling and field fabrication work.

This drill bit is suited for production and maintenance holemaking across residential and light commercial job sites. Its 9/64-inch diameter makes it a common choice for pilot holes, sheet metal work, and light structural drilling. The jobber-length series falls within the 0.1000 to 0.1500 inch decimal inch size range, covering standard fractional layout requirements. It is sold individually and is appropriate wherever a reliable, general-purpose HSS drill bit is needed without specialty coatings or coolant-through capability.

Key Features

• 9/64 inch (0.1406 inches) diameter for common pilot and through-hole applications
• 135-degree point angle reduces bit walking and lowers entry thrust requirements
• High speed steel construction handles a broad range of workpiece materials
• Bright, uncoated finish — no coating buildup to affect hole tolerances
• Jobber-length (3.5 inches overall) provides reach for most standard drilling tasks
• Two-flute regular spiral design promotes efficient chip evacuation

Compatibility

Designed as a standard jobber-length drill bit compatible with any 3-jaw or keyed drill chuck accepting a straight shank in the 9/64-inch diameter range, including handheld drills, drill presses, and CNC drilling setups.

Installation Notes

A licensed machinist or qualified tradesperson should secure the bit fully in the chuck before operation and verify chuck key removal prior to starting the drill. Always use appropriate work-holding and eye protection per shop safety standards. For ferrous metals, a cutting fluid or lubricant is recommended to extend tool life. Disconnect power to any drilling equipment before changing bits.
