Chicago-latrobe 45694 Jobber Drill Bit 24 Wire Hss 135 Split Point

Product Description

The CHICAGO-LATROBE 45694 is a jobber-length drill bit in wire gauge size 24, equivalent to 0.1520 inches in diameter, designed for high-performance metal drilling in demanding trade and production environments. Built from high speed steel with an oxide coating, this bit features a 135-degree split point for fast, self-centering starts without a center punch. The tapered web and web-thinned construction reduce thrust and heat buildup during drilling. The two-flute spiral design promotes efficient chip evacuation. At 3.125 inches overall length with a 2-inch flute length and a straight-cylindrical shank, the 45694 is well-suited for drill press and hand-drill applications in fabrication, maintenance, and field service work.

This bit is rated for use on cast iron, stainless steel, and carbon steel workpieces, making it appropriate for HVAC fabrication, plumbing rough-in, electrical conduit work, and general mechanical assembly. The Series 150ASP designation indicates heavy-duty grade performance meeting NAS 907 Type B standards. It is sold individually but requires a minimum order of 12 units per purchase, making it practical for shop stocking or service fleet kits where consistent bit supply is critical.

Key Features

• 135-degree split point for self-centering starts and reduced walking on hard metals
• Web-thinned, tapered web construction lowers drilling thrust and extends bit life
• Oxide coating improves surface hardness and heat resistance during high-speed cutting
• Right-hand cut with regular spiral flutes for reliable chip clearance
• Straight-cylindrical shank fits standard 3-jaw drill chucks without adapters
• Meets NAS 907 Type B specification for heavy-duty industrial drill bit performance

Compatibility

Designed for use in standard 3-jaw drill chucks accepting a 0.1520-inch straight-cylindrical shank. Rated for drilling cast iron, stainless steel, and carbon steel. Conforms to NAS 907 Type B specification as part of the Chicago-Latrobe Series 150ASP line.

Installation Notes

This bit is installed and operated by machinists, mechanics, and trade professionals using drill presses or portable hand drills. Secure the straight-cylindrical shank firmly in a properly sized chuck before operation. Use appropriate cutting fluid or coolant when drilling stainless steel or cast iron to extend bit life and maintain cutting edge integrity. Inspect the split point for chipping or wear before each use and replace bits that show visible edge degradation to avoid workpiece damage or bit breakage.
