A comprehensive product portfolio meets the needs of an extensive range of construction applications including railtrack, pipes, steelwork erection, structural engineering, petrochemicals, civil engineering, water and gas industries.

Cutting tools manufactured to internationally recognised standards provide the convenient solution wherever a hole has to be made, enlarged or neatly finished with consistent precision. The Powerbor hole cutting system from G&J Hall offers the highest quality electromagnetic drilling machines, annular hole cutters and accessories for quick, efficient and accurate drilling or hole cutting; capacities range from 12mm diameter to 100mm diameter.

Ratchet spanners and ratchet levers offer first class solutions for construction applications; particularly No 333 enclosed action non-reversible ratchet levers, and No 335 heavy duty reversible ratchet levers.
No 333 ratchet levers have a totally enclosed mechanism, which gives protection against particularly dirty conditions such as construction sites or trenches, or corrosive atmospheres.
No 335 ratchet levers are designed for the toughest loads. The racks and pawls are specially heat treated to withstand a higher load than the tubular handle - a safety feature designed to protect the operator if the lever is abused.

Standard quality combined drills and taps are manufactured from carbon chrome alloy steel and HSS with ground threads and special anti-shock treatment. All tools are suitable for general use in underpressure machines for the installation of feed connections in gas and water mains.
