IRWIN INDUSTRIAL TOOL CO - ACH 80220 Tap And Drill Bit Set

The IRWIN INDUSTRIAL TOOL CO - ACH 80220 10-24 NC 25 Tap And Drill Bit Set is built for technicians and hobbyists who need reliable threading and pilot drilling performance for automotive and mechanical applications. This compact kit combines precision-ground taps with a matching pilot drill to simplify hole preparation and threading tasks for common 10-24 NC fasteners.

Drills And Taps For Automotive Applications

Designed to work with portable drills and drill presses, the included #25 pilot drill delivers accurate lead-in holes while the 10-24 NC tap produces clean, consistent threads. Materials and fluting are optimized for chip evacuation, reducing cross-threading and improving tap life. The set is suitable for steel, aluminum, and other common substrates encountered in automotive repairs and assembly.

Compatible With Drills, Grinders, And Saws

While this kit is focused on tap and drill pairing, it complements a broader professional power tools toolkit that includes drills, grinders, and saws. The tap geometry and drill pilot are sized to integrate with drill chucks and accessory holders commonly found in automotive shops, making it simple to add thread cutting to existing workflows without extra setup complexity.

Professional Power Tools And Heavy Duty Automotive Power Tools

For professionals seeking consistency and repeatability, the 80220 set delivers predictable thread engagement and reliable pilot hole alignment. The compact case keeps components organized and ready for field use. Whether servicing brake components, fabricating brackets, or restoring threaded holes, this kit helps reduce rework and downtime when paired with heavy duty automotive power tools.

Technical buyers will appreciate the clear size pairing (10-24 NC with a matching 25 pilot drill) and the precision-ground finishes that support threaded assembly longevity. The set is an effective addition to any automotive tool chest or professional power tools kit where dependable tap-and-drill combinations are required. Fast shipping.
