Manufactured from bi-metal material with hardened teeth made from high speed steel with an 8% cobalt content for durability. Bi-metal holesaws offer increased safety as they will not shatter under load. The variable tooth pitch provides a fast and smooth cutting performance. They are ideal for use on a wide variety of materials including stainless steel, aluminium, sheet metal, mild metal, non-ferrous metals, cast iron, hard/soft wood, chipboard, plywood, plasterboard and PVC. Suitable for use in most variable speed power drills. Holesaw diameters 14 - 30mm require holesaw arbor FAI HSA16030 (Hex fitting) or FAI HSA1630S (SDS fitting). Holesaw diameters 32 - 210mm require holesaw arbor FAI HSA32150 (Hex fitting) or FAI HSA32150S (SDS fitting) or FAI HSA32150Q (Quick release).

General points when using holesaws ● Always make sure the workpiece is securely clamped, and select the correct speed for the diameter of holesaw being used and that of the material being cut. ● Always use the correct size arbor for the saw size selected, and make sure that arbors with drive pins have these fully engaged before use. ● Always use a lubricant when cutting steel and withdraw the holesaw from the cut at regular intervals to prevent clogging in deep holes.
