Chicago-latrobe 52444 Reduced Shank Drill Bit 11/16 in

Product Description

The CHICAGO-LATROBE 52444 is a reduced shank twist drill bit designed for portable drilling operations across a wide range of materials. Built from high speed steel with a coated finish, this bit measures 11/16 inches (0.6875 inches) in diameter and carries a 1/2 inch Weldon shank with three flats for secure chuck engagement. The 118-degree split point promotes accurate starting and reduces walking on entry. At 6 inches overall length with a 3-1/8 inch flute length, it handles moderate-depth holes in production and field settings. Licensed trades and general contractors install this type of bit when standard shank sizes do not match available tooling.

The 52444 is rated for general purpose portable drilling in wood as its primary workpiece material, with secondary compatibility noted for alloy steel, carbon steel, cast iron, and wood. The right-hand spiral flute design evacuates chips efficiently during through-hole and stopped-hole drilling. The Weldon shank with three flats makes it well suited for magnetic drill presses and high-torque portable drills where slip resistance is critical. The Series 190F designation identifies it within the CHICAGO-LATROBE catalog for consistent reordering and tool crib management.

Key Features

• 118-degree split point for accurate self-starting entry and reduced thrust requirement
• Weldon shank with three flats provides positive drive and prevents bit slippage in high-torque applications
• High speed steel construction with coated finish for extended tool life across multiple materials
• Right-hand spiral flute design promotes consistent chip evacuation
• Reduced shank design allows 11/16 inch cutting diameter with a standard 1/2 inch chuck or mag-drill arbor
• Diameter tolerance held to +0.0000 to -0.0012 inches for consistent hole quality

Compatibility

Designed as a general purpose reduced shank drill bit compatible with 1/2 inch Weldon-style chucks, magnetic drill press annular cutter arbors, and portable electric drills accepting 1/2 inch shanks. Rated for use in wood, alloy steel, carbon steel, and cast iron.

Installation Notes

Secure the Weldon shank fully into the chuck or arbor and tighten all set screws against the flats before use. Always disconnect or de-energize the drill before bit changes. When drilling metal, use appropriate cutting fluid to reduce heat buildup and extend bit life, even when the bit carries a factory coating. Ensure workpiece is clamped securely to prevent rotation during portable drilling operations.
