Offered is a vintage DoALL D-405 High Speed Steel Counter Drill Set manufactured by the DoALL Company of Des Plaines, Illinois.
This set includes eight counter drills housed in the original fitted wooden storage block along with the original factory box. The tools are marked DoALL and feature a range of sizes suitable for machining operations requiring drilling and countersinking in a single step.
These combined drill and countersink tools were designed for producing centered holes and countersunk openings in metalworking applications. The set retains its original presentation with matching holder and box, making it appealing to both working machinists and collectors of vintage American industrial tooling.
A quality USA-made machinist's tool set from a respected manufacturer.
