HSS Hole Saw 50 mm for Sheet Metal Punch from High-Speed Steel with Centre Drill and Spring for Stainless Steel, Iron and Aluminium
You already have the maximum available quantity in your cart.
This punch is designed for cutting circular holes of larger diameter 50 mm into thin sheets and metal profiles. It is made from high-speed steel HSS, making it suitable for iron, aluminium alloys, and stainless steel sheets. The guiding centre drill in the middle of the saw keeps it in precisely marked position during drilling, which is particularly important for large diameters. The entire hole is created in one drilling without gradual enlarging and additional filing of the edge. It can be used in workshops, on construction sites, and for home repairs.
The centre drill is surrounded by a telescopic spring, which compresses during the cut and ejects the cut disc from the saw after penetrating the material. Fully ground teeth around the circumference divide the cut evenly, and the edge of the hole remains regular. The saw is intended for materials with a thickness of up to 2 mm. A hole with a diameter of 50 mm is suitable for the passage of larger pipes and cable bundles, for ventilation holes in metal cabinets, or for the installation of round instruments, sockets, and grommets into covers and panels.

With larger diameters, the peripheral speed of the teeth is higher, so drill at low speeds and with even pressure. Mark the centre of the hole in advance with a centre punch and guide the saw perpendicular to the surface, preferably in a pillar drill. When drilling stainless steel, use cutting oil or other cooling methods to protect the teeth from overheating. Secure the workpiece firmly to prevent it from rotating with the saw during cutting. After use, remove chips and store the saw in a dry place. Remove the cut disc from the saw only after it has cooled down, as it heats up during prolonged drilling. During storage, protect the teeth from impacts with other tools to maintain their sharpness for a long time. Always check the saw before the next use.
The HSS hole saw 50 mm is an excellent choice where you need a large and clean circular hole in thin metal without complicated cutting. It is clamped by the triangular shank, which holds firmly in the jaws of the chuck and does not slip. Made from high-speed steel and thanks to the centre drill and telescopic spring, it is precise and comfortable to work with. It is useful for installation, maintenance, and modification of sheet metal structures and covers.
