Chicago-latrobe 53907 Jobber Drill Bit 7/32 in Hss Tin

Product Description

The CHICAGO-LATROBE 53907 is a jobber-length drill bit engineered for heavy-duty drilling in steel alloy and similar ferrous materials. It measures 7/32 inch (0.2188 inch decimal) in diameter with a 3-3/4 inch overall length. The bit features a 135-degree split point for fast, self-centering entry that reduces walking on hard surfaces without a center punch. A titanium nitride (TiN) coating increases surface hardness and reduces friction, extending tool life in production environments. The parabolic flute geometry promotes efficient chip evacuation, making it well suited for deep-hole work in tough materials. This bit is intended for use by machinists, pipefitters, electricians, and other trade professionals who require consistent, accurate hole size in metal fabrication and installation work.

The 53907 is designed for right-hand cutting in steel alloy as the primary workpiece material, though its TiN-coated high speed steel construction also handles cast iron, aluminum, and similar metals encountered in general trade work. The straight-cylindrical shank seats securely in standard 3-jaw drill chucks on corded drills, drill presses, and magnetic base drills. The 2-1/2 inch flute length provides adequate chip clearance for the jobber-length application range. With a shank diameter matching the cutting diameter at 7/32 inch, the bit fits any chuck capable of accepting that size. It is sold individually and suits both bench drilling operations and field installation tasks.

Key Features

• 135-degree split point for self-centering entry and reduced thrust force
• Titanium nitride (TiN) coating for extended wear life and reduced heat buildup
• Parabolic flute design promotes fast, efficient chip evacuation in deep holes
• Web-thinned, tapered web construction reduces cutting resistance in hard materials
• Heavy-duty drill bit grade rated for steel alloy and demanding production use
• Straight-cylindrical shank fits standard 3-jaw drill chucks without adapters

Compatibility

Designed as an OEM-style jobber-length drill bit for use in any standard drill press, corded drill, or magnetic base drill equipped with a chuck capable of accepting a 7/32 inch straight-cylindrical shank.

Installation Notes

A licensed machinist or qualified trade professional should select cutting speed and feed rate appropriate for the workpiece material before drilling. Secure the workpiece firmly before starting the cut, and ensure the drill chuck is tightened on all three jaws to prevent bit slippage. Apply cutting fluid when drilling steel alloy to reduce heat and extend bit life. Inspect the cutting edges for wear before each use and replace the bit if the TiN coating is fully worn through at the tip.
