Product description

The GRAPHITE bi-metal hole saws with diameters of 19, 29, 33, 51 and 68 mm are tools designed for drilling a wide range of materials. Made of HSS high-speed steel, they are characterised by durability and resistance to the high temperatures generated during drilling. Their height is 51 mm (for diameters 19, 29, 33 mm) and 44 mm (for diameters 51, 68 mm), and the maximum drilling depth is 38 mm. The products are fitted with a 1/2'' x 20 UNF thread (19, 29 mm) and a 5/8” x 18 UNF thread (33, 51, 68 mm). Compatible with the adapters included in the set – 3/8 Hex, 7/16 Hex.

GRAPHITE hole saws are suitable for work in materials such as metal, stainless steel (Inox), cast iron, brass, aluminium and wood. They are designed for use with drills and drill-drivers. To maintain optimum working efficiency, it is recommended to use the appropriate rotational speeds depending on the material. The tools will perform well both in workshops and during installation and renovation work.
