Chicago-Latrobe 57720 20-Piece Drill Set

This Chicago-Latrobe 57720 set supplies 20 jobber-length drill bits made from high-speed steel with a black oxide finish. The 118-degree point angle suits general-purpose drilling across metal, wood and plastic. It is built for trade professionals and serious DIY users who need a ready range of diameters in one case.

Installation and common issues

Each bit fits a standard three-jaw chuck; tighten securely and run at the correct speed for the material to avoid wandering. The black oxide coating reduces friction but can wear prematurely if the workpiece overheats or if cutting fluid is omitted on hard metals. Dull edges from excessive pressure are the most frequent cause of poor hole quality.

Check your setup before ordering

Verify that your drill’s chuck capacity covers the largest bit you plan to use and that the machine delivers variable speed for different materials. Confirm you have cutting oil or coolant available for steel work to protect the high-speed steel edges. Ensure the storage case dimensions suit your toolbox or workshop layout.
