RS PRO Bi-Metal Drill Bit Set, 51 mm Diameter, 9 Pieces, Arbor Included, Model 216-016

The RS PRO 216-016 Bi-Metal Drill Bit Set is a comprehensive kit designed for precise and efficient circular hole cutting in a variety of materials. With a maximum diameter of 51 mm, the set is perfectly suited for users who require clean, accurate holes in wood, plasterboard, metal, and similar substrates. Each component is manufactured from durable bi-metal, ensuring long life and reliable performance.

This 9-piece set comprises hole saws in key sizes including 16 mm, 20 mm, 25 mm, 32 mm, 40 mm, and 51 mm, along with arbors (6.5 mm, 9.5 mm), a 6.5 mm pilot drill, and a sturdy case. The case is designed with custom-cut foam inserts, keeping each tool readily accessible and protected against damage or loss. Secure latches ensure that the case stays closed during transit and site work.

RS PRO’s bi-metal hole saws utilize a special construction in which two types of metal are bonded together, providing the strength and flexibility needed for controlled, low-vibration cutting. This results in smoother holes and reduced risk of binding or damage to both tool and workpiece. The inclusion of the arbor and pilot drill ensures compatibility with standard power drills and stable, centered cutting starts.

Typical applications for this kit include the installation of door hardware, creation of cable management routes in office furniture, fitting ventilation ducts or light fixtures, and producing access points in plasterboard or wooden panels. Tradespeople such as electricians, plumbers, and construction professionals will find this set invaluable for streamlining repetitive cutting tasks with reliable results.

The energy-efficient cutting action helps to reduce the workload on cordless drills, prolonging their battery life. Advanced users will appreciate the clean-cutting performance and convenience of having all necessary tools in one organized, portable kit. This set is suitable for both workshop and site-based projects.

The RS PRO 216-016 kit is supplied in a high-visibility, robust polyethylene carry case, offering protection, organized storage, and easy identification of the correct or missing part. The thoughtful, comprehensive design makes it an essential addition to any serious tool collection for professionals in HVAC, building, maintenance, and facilities engineering sectors.
