DRALL+ improves force transmission
The new DRALL+ screwdriver range made by Stahlwille, based in
Wuppertal, Germany, allows the best possible fit between the hand and the
tool’s handle.
The rounded triangular cross-section of the handle fits into the palm of the user's
hand. In this way, the user can transmit large axial forces through the tool with minimum
effort. Stahlwille says that the handle sizes in this range are designed specifically to match
the drive profiles and the forces to be transmitted.
“The shape and position of both the hard and the soft handle components further improve force
transmission and ensure enhanced comfort and convenience when tightening screws. The textured black
tip of the DRALL+ reduces the tendency of the tip to slip out of the screw head.”
The DRALL+ range consists of the popular profiles and sizes. For tough working conditions, there is also a
version with a one-piece shaft and an impact head. The VDE series screwdrivers have been individually tested in a
water bath at 10,000V and are guaranteed to protect against up to 1,000V AC.
Safety for heavy industry
Norbar Torque Tools says it has had huge success with its TruCheck torque wrench tester for the car and more recently heavy
vehicles markets.
The TruCheck is a torque wrench tester with an accuracy of ± 1%, and a range of up to 1,000Nm. The basic model has no changeable
settings and is designed for click type wrenches, the operator simply sets a torque on the wrench, applies it to the tester, and the actual
torque applied is displayed on the clear LED screen.
Norbar says that the TruCheck Plus version is similarly simple, but the user can also select the units of measurement and also whether
the torque wrench is a click or dial type. In addition to the numeric display, a tolerance band can be set and the result (low, within
tolerance, or high) is indicated with amber, green or red lights.
The LED displays are visible in all light conditions and data collected can be downloaded to a PC for storage or for the production of
calibration certificates.
“We all know the potentially catastrophic consequences of incorrectly tightened wheel nuts,” said Philip Brodey of Norbar. “But we also
know that many people in the industry baulk at the cost and time involved in calibrating their tools regularly. That’s why we are delighted
to be able to offer this simple and cost-effective tester to help improve safety standards across the board.”
