RS PRO Counterbore and Pilot Drill Set, M3 to M10, High-Speed Steel, 12 Pieces, Model 132-019

RS PRO 132-019 Counterbore and Pilot Drill Set is a comprehensive 12-piece kit designed for precision hole preparation across industrial, mechanical, and engineering disciplines. This set features six counterbore Drill Bits in popular metric sizes, including M3, M4, M5, M6, M8, and M10, along with six matching pilot drills, making it ideal for applications where flush mounting of screws or bolts is essential.

Made from high-speed steel (HSS), each tool in the set offers outstanding durability and maintains sharpness under demanding conditions. The high-temperature resistance of HSS makes these tools suitable for continuous use in production environments, as well as for maintenance and repair tasks. The engineered geometry of the counterbores ensures accurate, flat-bottomed holes, while the pilot bits offer reliable guidance for the main drills, ensuring alignment and minimising the risk of misplacement.

The set is supplied in a sturdy polypropylene (PP) case which keeps the tools neatly organised and protected. This design supports both mobile engineers and workshop-based professionals who require fast access and safe storage for their tooling.

In practical application, this counterbore and pilot drill set excels in projects requiring concealed fixings or where aerodynamic performance is a consideration, as in the automotive or aerospace sectors. The selection of metric sizes covers most workshop requirements, offering flexibility in a single kit for everything from assembly and fabrication to repairs and upgrades.

Simplicity of use and excellent build quality place this RS PRO kit in a professional class, trusted by tradespeople in manufacturing, equipment service, structural assembly, and technical maintenance tasks. The robust design of each piece ensures repeated accuracy and a long service life under industrial loads.

The set includes six counterbores (M3, M4, M5, M6, M8, M10) and six pilot drills. All pieces are crafted from high-speed steel for optimum performance and increased lifespan. Provides precise solutions for both counterboring and pilot drilling tasks in a single kit.

Polypropylene hard case enhances portability and tool protection. Widely applicable across mechanical manufacturing, equipment repair, and technical installation tasks. Enables production of flat-bottomed holes for flush fitting of hardware and improved assembly aesthetics.
