Chicago-latrobe 70218 9/32 Inch Hss Tin Jobber Drill Bit

Product Description

The CHICAGO-LATROBE 70218 is a jobber-length twist drill bit designed for general-purpose drilling in metal fabrication, maintenance, and trade service work. Built from high speed steel with a titanium nitride (TiN) coating, it delivers improved surface hardness and extended tool life compared to uncoated HSS bits. The 118-degree standard point angle suits a wide range of common workpiece materials. At 4.25 inches overall length with a 2.9375-inch flute length, this bit fits standard drill chucks and magnetic drill press setups used by HVAC, plumbing, and electrical trades for sheet metal, structural steel, and cast iron drilling.

This bit is rated for drilling cast iron and steel, making it a practical choice for trade professionals who need a reliable jobber-length bit on mechanical, plumbing, or electrical rough-in work. The straight-cylindrical shank accepts standard three-jaw chucks. The regular spiral flute geometry and web-thinned point reduce thrust requirements and improve chip evacuation. It is sold individually and suits job-site drill presses, handheld drill drivers, and drill press fixtures commonly used across HVAC, plumbing, and electrical installations.

Installation Notes

Install and removal should be performed with the drill unplugged or the battery removed. Secure the workpiece before drilling to prevent rotation. Use cutting fluid or lubricant when drilling steel to extend bit life and maintain dimensional tolerance. Follow applicable OSHA and site safety requirements for rotating tool operation.
