Chicago-latrobe 69016 Jobber Drill Bit Wire 16 Hss

Product Description

The CHICAGO-LATROBE 69016 is a jobber-length twist drill bit designed for heavy-duty metal drilling applications. It carries a wire gauge size of 16, equal to 0.1770 inches in decimal diameter, and is manufactured from high-speed steel with a bright, uncoated finish. The 135-degree split point reduces walking and requires no center-punching on most surfaces. A parabolic flute geometry improves chip evacuation in deep-hole drilling, making this bit well-suited for production environments where throughput and hole quality matter. The straight-cylindrical shank measures 0.1770 inches in diameter and fits standard drill chucks without adapters.

This drill bit is rated for steel alloy as its primary workpiece material, placing it in common use among machinists, pipefitters, ironworkers, and maintenance technicians drilling structural steel, plate, pipe, and fabricated components. The Series 150DH designation indicates a heavy-duty jobber series intended for higher feed rates and longer run cycles than standard jobber bits. The 3-3/8 inch overall length and 2-3/16 inch flute length are consistent with standard jobber proportions, making it compatible with benchtop drill presses, hand drills, and magnetic base drills used across fabrication and field service environments.

Key Features

• Wire size 16 diameter: 0.1770 inches, held to a tolerance of -0.0007 to 0.0000 inches
• 135-degree split point with web thinning reduces entry force and minimizes bit walk
• Parabolic flute profile accelerates chip clearing in deep or interrupted cuts
• High-speed steel construction handles steel alloy workpieces at sustained cutting speeds
• Tapered web configuration adds rigidity while keeping flute geometry efficient
• Bright uncoated finish provides a consistent baseline for re-sharpening and inspection

Compatibility

Designed as a heavy-duty OEM-style jobber drill bit for use in standard straight-shank drill chucks across drill presses, hand drills, and magnetic base drills; primary workpiece material compatibility is steel alloy as specified by the manufacturer.

Installation Notes

Install and remove this bit only with the drill fully powered down and the chuck key secured. Ensure the chuck jaws are clean and fully tightened on the straight-cylindrical shank before beginning any cut. Drilling into steel alloy workpieces typically requires appropriate cutting fluid to extend bit life and maintain hole tolerances. Coolant-through is not supported on this bit, so external fluid application is the correct method.
