Metabo Power Grip

Ever find yourself on your back, contorted into a pretzel-like shape while coping with dozens of tiny screws, bolts and nuts? Under-dash work is typical of this cramped quarter service, and if you’re in a hurry, as most are in this industry, a power screwdriver can be a real timesaver. Metabo, a name unfamiliar to most in the automotive service trade, has an unusual tool called the Power Grip that’s ideal for close quarters work. SSGM tested the Power Grip in typical light duty under-dash work.

The unit has an unusual “banana” shape that falls readily to hand, and allows the bit to reach tight spots both vertically and horizontally. Bits insert with little force without a collet lock, and a clutch ring rather like a cordless drill controls torque. In fact, the Power Grip feels like a miniature cordless drill, and was capable of spinning a hex-mounted 3/16″ bit to open up a misaligned screw hole. The tool feels substantial and comes in a plastic case with a spare battery and charger. The 4.8-volt battery doesn’t suffer from the “memory effect” of older NiCad types, so it’s O.K. to recharge a partially full battery. The included charger maintains a trickle charge on the battery, so one can be safely kept topped up ready for use. Batteries charge fully in approximately two hours. Operation is simple, with a two-position trigger controlling forward and reverse motion. The unusual rounded battery pack also allows the user to put palm pressure on the bit in awkward positions, especially useful with the automatic spindle lock which holds the bit stationary for manual driving. Maximum tightening torque is substantial 133 inch-pounds, and mercifully for a European-designed tool, the spindle uses the classic 1/2″-20 UNF thread. The only criticism of note is the charger, which would be better designed as a table or wall-mount stand rather than the plug-in type. Metabo’s Power Grip is an interesting option for faster work in under dash, trim or similar light driving operations. Power Grip carries a MSRP of $190, which includes the tool, two batteries, charger and case, and is available exclusively at industrial supply distributors such as Acklands Grainger, Fastening House, CTF Supply and others.
