Hertel 16692246 Jobber Drill Bit 5/16 in Solid Carbide Tin

Product Description

The HERTEL 16692246 is a jobber-length drill bit designed for precision drilling in demanding metal-cutting applications. Built from solid carbide (material grade C2) and finished with a titanium nitride (TiN) coating, this bit delivers extended tool life and reduced friction compared to standard high-speed steel alternatives. It features a 118-degree standard point angle with web thinning for easier penetration and reduced thrust, and a two-flute spiral configuration for efficient chip evacuation. At 5/16 inch (0.3125 inch decimal) in diameter, it is suited for machinists, maintenance technicians, and fabricators working with harder materials where bit longevity matters.

This bit is used in general-purpose metal drilling where a jobber-length reach is appropriate. The straight-cylindrical shank accepts standard drill chucks on floor-standing drill presses, bench-top units, CNC machining centers, and handheld power tools. A right-hand cutting direction means it works with all standard clockwise-rotating spindles. At 3-3/4 inches overall length with a 2-3/8 inch flute length, it provides adequate reach for most through-hole and blind-hole applications in ferrous and non-ferrous stock without excessive overhang.

Key Features

• Solid carbide construction (grade C2) for hardness and wear resistance in demanding materials
• Titanium nitride (TiN) coating reduces friction and extends tool life between sharpenings
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Two-flute regular spiral design promotes consistent chip evacuation
• Straight-cylindrical shank fits standard drill chucks without adapters
• Diameter tolerance of -0.0005 to 0.0000 inches for accurate, on-size holes

Compatibility

Designed as a Series 450 jobber-length replacement drill bit suitable for standard drill chucks accepting a 5/16-inch straight-cylindrical shank, compatible with drill presses, CNC machining centers, and handheld power tools with clockwise-rotating spindles.

Installation Notes

Install and remove drill bits only with the spindle fully stopped and the machine powered down or isolated. Secure the straight shank firmly in a properly sized chuck and verify runout before beginning a drilling cycle. Always use appropriate cutting fluid or coolant recommendations for the workpiece material, even though this bit does not support coolant-through delivery. Wear appropriate eye protection per shop safety standards when operating drilling equipment.
