Hertel H95006016 Jobber Drill 5/16 in Hss 137 Deg

Product Description

The HERTEL H95006016 is a 5/16-inch high speed steel jobber-length drill bit designed for general-purpose holemaking in metal, wood, and plastic. It features a 137-degree split point that reduces walking and allows the bit to start on contact without a center punch. The oxide and gold coating improves lubricity and extends tool life under moderate heat. At 4.5 inches overall length with a 2.5-inch flute, it fits standard drill chucks and magnetic drill press setups used in trade and light industrial work. HVAC, plumbing, and electrical contractors reach for jobber-length bits like this for bracket mounting, sheet metal, and structural steel drilling tasks.

This bit is suited for right-hand drilling operations in residential and commercial trade applications. The 2-flute spiral design provides efficient chip evacuation in through-hole and blind-hole scenarios. The heavy-duty grade construction holds up in repetitive production drilling as well as single-trade field work. Three flats on the shank help prevent slippage in standard 3-jaw chucks. It is sold individually but requires a minimum order of 6 units per order.

Key Features

• 137-degree split point reduces bit walking and eliminates the need for center punching on most surfaces
• High speed steel construction with oxide finish for improved heat resistance and lubricity
• Heavy-duty grade rating for repetitive drilling in trade and light industrial environments
• 2-flute regular spiral design promotes clean chip evacuation in metals and plastics
• 3-flat shank prevents rotation in standard 3-jaw drill chucks
• ANSI specification designation ensures dimensional consistency

Compatibility

Designed as a standard jobber-length drill bit compatible with any 3-jaw drill chuck accepting a 5/16-inch round shank, including handheld drills, drill presses, and magnetic base drills commonly used in HVAC, plumbing, and electrical trades.

Installation Notes

Secure the bit fully in the chuck before operation and verify the chuck key is removed before powering the drill. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat buildup. Wear ANSI-rated eye protection and secure the workpiece before drilling. Inspect the cutting edges before each use and replace if chipping or dulling is evident.
