Chicago-Latrobe 55480 HSS Drill Bit
The Chicago-Latrobe 55480 is a reduced-shank drill bit manufactured from high-speed steel. Its 118-degree point angle suits general-purpose drilling across a range of materials. The black oxide finish helps resist corrosion during storage and use.
Practical Limits of 118-Degree HSS Bits
The 118-degree point is not optimised for hard or abrasive alloys where a split point or cobalt blend would reduce walking and heat. High-speed steel loses hardness faster than carbide at elevated temperatures, limiting sustained high-speed drilling. The reduced shank requires a chuck capacity matching the shank diameter, so it will not fit smaller drill chucks. Users needing to drill very deep holes or tough metals should consider specialised geometry or tool materials.
