140 mm Bimetal HSS M42 Core Drill Large Hole Saw for Metal with Centre Drill and Spring Orange for Ventilation Openings and Passages
You already have the maximum available quantity in your cart.
The bimetal core drill with a diameter of 140 mm is designed for cutting really large circular holes in both metal and wood. The teeth of the drill are made from HSS M42 high-speed steel, which is used for machining steel, stainless steel, iron, and aluminium. The core drill is also suitable for wood and wooden boards. The wide gaps between the teeth during drilling allow for effective chip removal. The 140 mm diameter is ideal for ventilation openings, pipe passages, or the installation of large round components into panels and covers. The core drill can be attached to a standard drill or cordless screwdriver with a chuck, allowing you to work in the workshop or directly on site.
The tool consists of the core drill with teeth, shank, guiding drill, and spring. The guiding drill ensures precise centring: it first creates a small hole and then guides the core drill along the circumference, preventing it from slipping on smooth surfaces. The spring threaded onto the drill pushes the cut-out disc out after the cut is completed. The hole saw arrives assembled and ready for attachment. On the side of the casing, you will find a longitudinal slot for easily removing a stuck cut-out. The orange surface of the core drill is easily recognisable among other tools.

When working with a core drill of this large diameter, it is important to hold the drill firmly with both hands and secure the workpiece with a clamp. Mark the centre of the hole in advance so that the guiding drill starts at the correct location. Drill metals at a slower speed with consistent pressure, and cool steel and stainless steel with cutting oil or emulsion. Higher speeds can be used for wood. If the material is thicker, occasionally pull the core drill out of the cut and remove chips from the groove. It is advisable to support thin sheet metal with a wooden board to prevent it from bending under pressure and to keep the edge of the hole straight. Start the cut slowly and increase the speed once the teeth have created a groove around the entire circumference. After use, clean the tool and store it in a dry place.
The 140 mm core drill is ideal for situations where you need a large and regular 140 mm hole without cutting with a saw. Thanks to its bimetal construction, it can handle both metal and wood and can be used repeatedly. The guiding drill and spring for cut-out removal speed up and simplify the work. It is suitable for use in the workshop, during ventilation installation, and when modifying panels and covers. It complements a set of smaller hole saws when you need a truly large diameter. Once unpacked, simply attach the core drill to the drill and start drilling the first hole.
