The Irwin 4935607 Titanium Nitride Coated High-Speed Steel Drill Bit Set delivers a complete 15-piece lineup of general-purpose drill bits housed in a rubber over-molded Pro Case.

Each bit features a 135-degree split-point tip that starts drilling immediately with less force and eliminates "walking" across the work surface, making this Irwin set a dependable choice for professionals who need consistent, accurate holes on the jobsite. The rubber over-molded Pro Case keeps every bit indexed and protected, so the set travels well between the shop and the field.
