TOOLS Norbar&#x2019;s non-magnetic solution

Norbar Torque Tools, based in Banbury, UK, has launched its fi rst ever non-magnetic torque wrench, which it says is proving invaluable for medical equipment maintenance, notably in the MRI fi eld. It also has further applications across a range of industries wherever tools have to be used in the presence of a strong magnetic fi eld.

be diffi cult and hazardous. Potential incidents can occur from tools locking onto magnets and tools fl ying out of control under magnetic attraction. In both cases there is serious risk of injury to the operator and damage to

sensitive and expensive equipment. The new Norbar wrench is acceptable for the majority of MRI scanners in use today. Philip Brodey of Norbar explained that manufacturing the non-magnetic torque wrench required carefully selected and tested

materials to replace the ferrous components present in standard torque wrenches. &#x201C;The new wrench is designed and manufactured to the same high standards as our other torque tools, but has an extremely low magnetic footprint,&#x201D; he said. Other maintenance applications where the Norbar Non-Magnetic torque wrench will be a real benefi t includes clean rooms, radar transmission centres, precision magnetic equipment, permanent magnetic generators (PMGs) and nuclear products.

Safe, advanced, technical - that&#x2019;s GEDORE

When products leave GEDORE&#x2019;s 10,000m&#xB2; radio-controlled logistics centre in Remscheid, Germany, the user can be certain that the three above factors apply as the prime standard from the fi rst technical drawing through to actual production.

his also holds true for the 2011 products which include angled combination pliers, the hexagonal UD profi le socket and the DREMOMETER EK. GEDORE highlights that the hot drop-forged 8248 combination pliers with a 60&#xB0;angled head is suitable for the toughest of demands placed on them. The angle ensures that the power of the hand is optimally used. It also prevents

any forced positioning of the hand thus substantially reducing stress on both joints and tendons and you keep the work piece in view at the same time. Inductively hardened cutting edges and specially offset teeth in the grip surfaces ensure both a clean cut and the best-possible technical grip on tubes and screws. The GEDORE Unit Drive profi le &#x2013; known as the UD profi le &#x2013; is now also available for hexagonal sockets. GEDORE explains

that the uniform distribution of forces onto the fl anks of the screw head lowers the notching effect and stops the screw head profi le from spinning. For controlled screw tightening between 600Nm - 1,500Nm there is only one answer states GEDORE and that is the

GEDORE DREMOMETER EK, an optimum torque wrench for vital screwed fastenings at industry and wind power plants. Classifi ed to DIN EN ISO 6789:2003 Type II Class A, with a factory certifi cate and working accuracy of +/- 3% tolerance of

scale set torque, the torque wrench exceeds the standard specifi cation by +/- 4%. GEDORE also points out that due to the torque wrench&#x2019;s lightweight and robust aluminium-alloyed housing, it is both extremely kind-on-hands and dependable under tough continuous work. As both square drive and pivot are on a single axis, two-handed operation and actuation done away from the hand grip produce no shifts in value and no impact on accuracy. The three products are in the current 2011 GEDORE catalogue, which is now available free of charge.
