Chicago-latrobe 47525 1/2 Inch Hss Jobber Drill Bit

Product Description

The CHICAGO-LATROBE 47525 is a jobber length drill bit designed for general-purpose drilling in metal fabrication and maintenance applications. Built from high speed steel with an oxide coating, this bit offers solid wear resistance during routine drilling tasks. It measures 6 inches in overall length with a 4.5-inch flute length and a 0.5-inch diameter. The 118-degree standard point angle and web-thinned tip reduce walking on entry and lower thrust requirements when starting a hole. Two spiral flutes with a regular helix clear chips efficiently during through-hole drilling. This bit is sized and configured for use by machinists, pipefitters, ironworkers, and general maintenance trades.

The 47525 is suited for drilling cast iron and steel in both shop and field conditions. Its tanged shank seats positively in drill chucks and compatible holders. The jobber length format fits standard drill presses, hand drills, and magnetic base drills without an extension. The general-purpose grade makes it a practical stock bit for routine hole-making tasks in structural steel, pipe, plate, and similar ferrous materials where tight tolerances are not required.

Installation Notes

Install and remove this bit with the drill motor fully powered down and the chuck key removed from the work area before securing.
