HSS Bi-Metal Hole Saw 50 mm with Guide Drill and Spring for Core Ejection Orange for Holes in Sheet Metal and Wood
You already have the maximum available quantity in your cart.
The bi-metal hole saw with a diameter of 50 mm is designed for cutting precise circular holes in metal sheets, stainless steel, iron, aluminium, and wood. The cutting part is made from high-speed steel HSS with M42 tooth design, which can handle harder materials. The crown features prominent sharp teeth with large gaps that help remove chips from the cutting area. The 50 mm diameter is suitable for waste pipe passages, ventilation and exhaust openings, or cable glands in worktops and covers. The hole saw can be attached to a standard drill or cordless screwdriver with a chuck.
In the centre of the crown is a guide drill with a spring, which first drills the centre and then keeps the hole saw in precise position to prevent it from slipping on the surface during the start. The spring around the drill helps eject the cut disc of material from the crown after the cut is complete. The hole saw is supplied assembled with a shank and guide drill, so it can be easily attached to the drill chuck right after unpacking. The orange finish of the crown protects it and makes it easier to find in the tool case.

Before drilling, mark the centre of the hole with a centre punch or pencil, and the guide drill will easily find the correct spot. It is advisable to securely clamp or hold the workpiece to prevent it from rotating during the cut. When drilling into metal, use lower speeds and consistent pressure to prevent the teeth from overheating unnecessarily. Higher speeds can be used for wood and plastic than for metal. For steel and stainless steel, it is advisable to continuously cool the cutting area with cutting oil or emulsion. For thicker materials, it is good to occasionally interrupt the cut, remove the chips, and then continue. After use, clean the crown of chips and dust and store it in a dry place to keep the teeth sharp for as long as possible.
The 50 mm hole saw is a simple way to achieve a clean and precise hole without the laborious task of sawing or drilling with multiple bits. The teeth with M42 tooth design handle both sheet metal and wood, and the guide drill keeps the crown in place from the very first moment. Thanks to its bi-metal construction, which is flexible and durable, the crown can be used repeatedly on various materials. It is suitable for both craftsmen and DIY enthusiasts who need to quickly and cleanly create a larger hole with a diameter of 50 mm. Just clamp it into the drill, and you can start drilling.
