Chicago-latrobe 41693 Jobber Drill Bit 23 Wire Hss Tin

Product Description

The CHICAGO-LATROBE 41693 is a jobber-length drill bit in wire gauge size 23 (0.1540 inches decimal equivalent), designed for high-performance metal drilling in demanding trade and industrial applications. Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction compared to uncoated bits. The 135-degree split-point tip reduces walking on entry and requires less feed pressure than conventional 118-degree points. With an overall length of 3-1/8 inches and a 2-inch flute length, this bit fits standard jobber-length applications. Licensed HVAC technicians, machinists, pipefitters, and general trade mechanics will find this bit well-suited for precise-diameter drilling in ferrous and hard materials.

The 41693 is rated for use in cast iron, stainless steel, and steel workpieces, making it a practical choice for mechanical contractors and industrial maintenance technicians who need repeatable hole quality in tough substrates. The right-hand spiral flute with regular spiral type provides efficient chip evacuation during through-hole drilling. The straight-cylindrical shank with a 1.125-inch shank length seats securely in standard drill chucks and drill press collets. This bit conforms to NAS 907 Type B standards, which is relevant for shops and contractors working to aerospace or precision military-specification tolerances.

Key Features

• Wire gauge size 23 with 0.1540-inch decimal equivalent and a tight diameter tolerance of -0.0007 to 0.0000 inches
• 135-degree split-point geometry reduces bit walking and lowers required feed pressure on hard materials
• TiN (titanium nitride) coating improves surface hardness and extends cutting life versus bare HSS
• Web-thinned, tapered web configuration supports cleaner chip formation and reduced thrust in deep holes
• Meets NAS 907 Type B specification for use where dimensional and material standards are required
• Right-hand, 2-flute spiral design with regular spiral type promotes consistent chip evacuation in steel and cast iron

Compatibility

Designed as an OEM-style replacement or direct-use jobber-length drill bit rated for cast iron, stainless steel, and steel workpieces in applications conforming to NAS 907 Type B standards. Fits any standard drill chuck or drill press accepting a straight-cylindrical shank.

Installation Notes

Install in a properly rated drill press, hand drill, or CNC spindle with a chuck matched to a straight-cylindrical shank. Secure the shank fully before operation and confirm chuck tightness to prevent runout, which can cause oversize holes and accelerated bit wear. Use appropriate cutting fluid or coolant when drilling stainless steel to manage heat buildup, as this bit does not include through-coolant capability. Always wear eye protection and follow applicable OSHA or shop safety protocols when drilling metal.
