Chicago-latrobe 69019 Jobber Drill Bit Wire 19 Hss 135

Product Description

The CHICAGO-LATROBE 69019 is a jobber length drill bit designed for heavy-duty drilling in steel alloy and similar ferrous materials. It measures 0.1660 inches in diameter (wire size 19) with an overall length of 3.25 inches and a flute length of 2.125 inches. The 135-degree split point reduces walking and requires no center punch on flat stock. Made from high speed steel with a bright uncoated finish, this bit is built for production drilling environments where consistent sizing and clean entry matter. Licensed HVAC, plumbing, electrical, and mechanical contractors reach for this format when drilling bracket holes, conduit knockouts, and sheet metal penetrations.

The 69019 suits general metalworking and trade installation tasks that call for a wire-gauge drill in the 0.15 to 0.20 inch range. The parabolic flute geometry evacuates chips efficiently, reducing heat buildup in deeper holes. The straight-cylindrical shank fits standard 3-jaw chucks on corded and cordless drill drivers. Right-hand cut orientation is standard for conventional drill press and hand-held operation. This series 150DH bit carries a heavy-duty grade rating and is sold individually, making it straightforward to replace a single worn bit without purchasing a full index set.

Key Features

• Wire size 19 diameter: 0.1660 inches with a tight tolerance of -0.0007 to 0.0000 inches
• 135-degree split point reduces thrust and eliminates center-punch requirement on flat surfaces
• Parabolic flute profile promotes rapid chip ejection and reduced heat in deep-hole drilling
• High speed steel construction handles steel alloy and comparable workpiece materials
• Web-thinned, tapered web design lowers cutting resistance at the tip
• Straight-cylindrical shank fits standard chucks; right-hand cut for conventional rotation

Compatibility

Designed as an OEM-style replacement or production-use jobber drill bit for applications requiring wire size 19 (0.1660 inch) diameter in the CHICAGO-LATROBE Series 150DH heavy-duty line. Compatible with any standard 3-jaw chuck accepting a 0.1660-inch straight-cylindrical shank.

Installation Notes

This bit is installed and operated by machinists, tool-and-die workers, and trade professionals using drill presses, magnetic-base drills, or handheld drill drivers. Secure the shank fully in the chuck before operation and verify chuck key is removed before powering the tool. For best results in steel alloy, apply a cutting fluid or cutting oil to extend bit life and maintain tolerance. Inspect the cutting edges before each use and replace if chipping or dulling is observed to avoid oversized holes or workpiece damage.
