70 mm Bi-Metal HSS M42 Hole Saw with Guide Drill and Spring Orange for Holes in Sheet Metal, Stainless Steel and Wood
You already have the maximum available quantity in your cart.
The bi-metal hole saw with a diameter of 70 mm is designed for cutting clean circular holes in steel sheet, stainless steel, aluminium, iron, and wood. The cutting part of the saw is made of HSS M42 high-speed steel, allowing it to handle tougher metal materials. The wide gaps between the teeth help to remove chips from the cut, preventing the saw from clogging. A hole of 70 mm is suitable for pipe passages, cabinet ventilation, or cable grommets in worktops. The hole saw can be mounted in a standard drill or cordless screwdriver with a chuck. It is ideal for workshops, construction sites, and occasional home repairs.
At the centre of the saw, there is a centre guide drill that first drills a small hole and then guides the hole saw precisely along the circumference. This ensures that the saw does not slip sideways on smooth metal during the start. Surrounding the drill is a spring that helps eject the cut disc from the saw once the material has been pierced. The hole saw comes pre-assembled with a shank and guide drill, so you can simply mount it and start working upon unpacking. The side longitudinal slot in the saw's casing makes it easier to remove any piece of material that may become lodged inside. The orange surface of the saw is easily visible among other tools.

Before drilling, mark the centre of the future hole, preferably with a centre punch, so that the guide drill can find the correct spot immediately. Securely clamp or reliably hold the workpiece to prevent it from rotating during the cut. For metals, work at lower speeds with a steady, moderate pressure; for wood and plastic, you can increase the speed. It is advisable to cool steel and stainless steel while drilling with cutting oil or emulsion to reduce heat on the teeth. When cutting through thicker materials, it is good to occasionally pause the drilling and clear the chips from the groove. If drilling into thin sheet metal, support it with a piece of wood to achieve a cleaner edge and prevent the sheet from bending. After use, clean the saw of dust and shavings and store it in a dry place.
The 70 mm hole saw replaces the tedious process of cutting holes with a saw or gradually drilling multiple smaller holes. The bi-metal construction with cutting teeth made of high-speed steel allows the saw to be reused on various materials. It serves craftsmen, plumbers, and DIY enthusiasts who need to quickly and accurately create a 70 mm circular hole in metal or wood. The guide drill and spring significantly simplify the task. Just mount the saw in the drill, position it on the marked centre, and start cutting.
