Tool review: Mighty quiet -- King Tony America's NC-4232Q wrench

Obviously, ½-inch-drive air wrenches are plentiful in today’s market, so what makes this one worthy of consideration? King Tony America’s new NC-4232Q is touted as a “quiet” wrench, hence the “Q” suffix in the part number in the firm’s “Mighty 7” series.

The “Q” isn’t in the part number just to fill space. At a mere 83 dba, this cute little guy is pleasing to the ears, something you immediately notice when you squeeze the trigger for the first time. Sure, you can hear it, but it’s notably quieter than you expect from any air wrench.

One of the very first features to catch my attention was the forward/reverse lever. This is a rotary lever, located on the left side, immediately behind the trigger. The lever offers a very healthy surface area for positive no-guessing-involved directional choice. Your thumb (assuming you’re right-handed) intuitively finds it and snaps it into forward or reverse without the need to hunt for it. The location, design and size of the lever allows you to change direction in a heartbeat without the need to move your operating hand or your trigger finger. I really like this lever.

This little bugger is strong, quiet and ergonomically a pleasure to handle. The smallish size, coupled with the composite grip, results in a mere 3 lbs. of weight, reducing wrist and arm strain. Plus, the stubby length (drive to rear of the body) measures only 4.75 inches, making it ideal for tight spaces, in addition to offering a pleasing balance. The weight feels very centered relative to the hand,without being nose or tail heavy. Height is 6.75 inches.

The trigger covers a lot of ground, offering a healthy 1.75 inch height of finger contact area, which will accommodate even the heaviest of gloves.

The grip area design indicates that some thought went into operator comfort. The bottom of the grip slants outward, and the top of the grip (immediately under the trigger) features a radiused extension. The result: Your index finger, ring finger and pinky are comfortably captured between these two rests, for a very positive grip and handling control. In short, the grip immediately feels great in the hand.

There’s no good reason to toss any tool around the shop just to see if it will live. Besides, what does that really prove? Regardless, we played with this little muscle-gun, tackling some stubborn fasteners up to 5/8-inch thread diameter. We also “accidentally” dropped it several times just to see if anything would crack or cause a malfunction. I’m sure that if you abuse any air gun enough, you’ll have a problem, but we abused this cutey and just like the Energizer bunny, she just kept rockin’ away. While the torque was exceptional in both reverse and forward, what really sold me was the reduced noise level, the comfy grip and that lovely directional lever.
