Chicago-Latrobe 49532 1/2" HSS 118° Jobber Drill Bit

Chicago-Latrobe 1/2 inch HSS jobber drill bit

The Chicago-Latrobe 49532 is a high-speed steel drill bit with a 118 degree conventional point. It is designed for general-purpose drilling in metal, wood and plastic where a standard jobber length is required. The black oxide finish helps resist corrosion and reduces friction during use. Suitable for trade professionals and DIY users needing a reliable replacement bit.

Practical limits of the 118 degree conventional

The 118 degree point angle works well in softer materials but can wander on hard or abrasive surfaces without a pilot hole. High-speed steel loses hardness at elevated temperatures so sustained high-speed drilling in tough alloys will dull the cutting edges quickly. The jobber length provides standard reach but lacks the rigidity of shorter stub drills or the depth capacity of taper-length bits. Users needing extended reach or specialised geometry should consider alternative bit styles.
