DEWALT’s lead design engineer for drills was tasked with designing a high power right angle drill that is lightweight, compact, and portable. The goal with the design was to maximize performance while minimizing the size of the tool. The design would incorporate a mechanical clutch built to limit maximum torque output to 70 ft-lbs. Absent the clutch, with the huge gear reduction of 75:1, the drill would be capable of producing a lock rotor torque at the spindle of 175 ft-lbs, transmitted directly to the operator of the tool. It was determined early on that the clutching thrust required in the space available could only be achieved by a Disc Spring design. Compared to conventional coil springs, Disc Springs offer a higher load capacity in less space. Additionally, longevity and reliability is a high measure of quality for professional tools used on a daily basis. The life and performance warranty of the tool was reliant on the Disc Spring design.

Thanks to the Inverter group it is possible to remove the entire mechanic clutch group, that has over 30 different part numbers (50 items). This upgrade also has the advantage of bringing significant savings during the maintenance phase, not just as regards the items that are removed, but also in terms of the gears, pins and bearings, since “softer” operations will prolong their productive lifetimes.

Tohnichi's AMRD series torque screwdriver provides same features as series RTD, except designed for tightening small screws. Thereby this model is ideal for assembly of watches, precision electronic equipment, computer, etc. Via micrometer scale torque can easily and quickly be adjusted. Index finger holding feature allows the operator to tighten with precise movements. Upon reaching the set torque, it clicks to signal tightening is complete. Integrated rotary clutch mechanism reliably prevents over-torque. Key Features: - Accuracy and calibration compliant to ISO 6789 type II class D - Micrometer adjustable - Clockwise direction - Click signal - Rotary clutch - Calibration certificate (ISO/JIS) incl. Options: - Counterclockwise tightening model available on request. - Optionally available in metric (gf·cm) or in english units (lbf·in, ozf·in).

Many customers ask us what ROPP is and the simple answer is Roll On Pilfer Proof closure. Simply put it is an unthreaded aluminum shell that is placed on and pressed down onto the bottle neck while thread forming wheels spin around the shell and press against it to conform to the existing threads of the bottle and locking ring. In many respects a ROPP capper resembles a chuck capper although since it is not torquing a cap there is no clutch mechanism required. ROPP capping machines are available as a single head to multiple head high speed rotary systems. The big advantage of a ROPP capper machine is that it is sealing the product at the same time it is providing tamper evident security. The big disadvantage is that it is expensive to run more than one size cap. The neck and threads of the bottle must also be hard enough to withstand the pressure required to form threads such as glass or hard plastic.
