Chicago-latrobe 45672 Wire Size 2 Jobber Drill Bit Hss

Product Description

The CHICAGO-LATROBE 45672 is a jobber-length twist drill bit designed for high-performance drilling in demanding trade and industrial applications. Built from high speed steel with an oxide coating, this Series 150ASP bit carries a wire gauge size of 2, equal to 0.2210 inch decimal diameter. The 135-degree split point with web thinning reduces walking on entry and lowers the thrust required to start the cut. With an overall length of 3-7/8 inches and a flute length of 2-5/8 inches, the bit is sized for standard jobber-length reach in handheld and machine-mounted drilling operations. It meets NAS 907 Type B standards and is rated heavy duty.

This drill bit is intended for use on cast iron, stainless steel, and steel workpieces in fabrication, maintenance, and repair environments. The straight cylindrical shank fits standard drill chucks without adapters, making it a practical choice for machinists, pipefitters, ironworkers, and general maintenance technicians. The regular spiral flute promotes chip evacuation, reducing heat buildup during extended cuts. It is sold individually, making it a straightforward replacement or addition to a tool kit without a minimum quantity commitment beyond a single unit.

Compatibility

Designed as an OEM-style jobber-length drill bit suitable for use in standard drill chucks, drill presses, and CNC machine spindles accepting straight cylindrical shanks at 0.2210 inch diameter. Rated for primary workpiece materials including cast iron, stainless steel, and steel.

Installation Notes

This bit is installed by a machinist, maintenance technician, or trade professional using a standard keyed or keyless drill chuck sized for the 0.2210-inch straight shank. Ensure the chuck is fully tightened and the workpiece is securely clamped before beginning the cut. Always wear appropriate eye protection and follow applicable OSHA and shop safety requirements when operating drilling equipment. Coolant-through operation is not supported on this bit; use an appropriate cutting fluid applied externally when drilling stainless steel or hardened steel to extend bit life.
