Tool Review Fastening drawer slides to plywood, without stripping or breaking the screws, requires good finesse from the trigger and a gentle approach. Ryobi was the slowest. While the impact action was taking place, it wasn't rattling my teeth or making the driver uncomfortable to hold on to. Additionally, although I drove a lot of long screws with each tool, I didn't notice excessive heat buildup from their motors. Mini impact drivers aren't as noisy as a router, but you should definitely wear hearing protection when driving fasteners with these machines. This is especially important when you've got your head inside a cabinet while you're installing hardware. That said, no one driver was noticeably louder than others in this test.
Makita This 10.8-volt tool provides a nice overall balance between power, finesse, feel and price. The worklioht remains on for 10 to 15 seconds after you release the trigger, which is a useful convenience. www.makita.com ♦ (800) 462-5482 For more info on RE^IO the web: use our Fj'l'llfl^kl TD090DW $146 Drilling Test All right, I know these tools are designed to drive, not necessarily drill, but I couldn't help but wonder how much wood a driver could drill if a driver could drill wood. What I was really looking for here was how large a hole I could drill before the impact function engaged. If the tool starts impacting while drilling, it slows down the drilling process. All the tools succeeded at what I'd consider to be a must-have operation: spinning a countersink bit for a #8 screw into melamine without the impact starting up. That's great, since pre-drilling with a countersink and then driving a screw is a pretty standard assembly operation for woodworking. Then, I switched to hard maple and found that the largest hole I could drill without the impact engaging was 3/16" diameter. I had to be more careful feeding the bit on some tools than others. Although this isn't a huge bit, it's still relatively good news since a 3/16" hole is commonly used for pull and knob screws. The bottom line is that these tools excel at driving, but they are still OK for drilling small holes. Some of the drivers are available in kits that include a drill, which makes a handy combo pack. Or, buy an accessory three-jaw chuck, which locks into the hex drive and would be handy for using those occasional small drill bits. Hitachi sells one (part #725045) for around $30. Getting a Grip My hand measures 8" from the heel of my palm to the tip of my middle finger; my wife's measures 6". I had no trouble gripping and using any of these tools, but my wife really appreciated the smaller grip size of the Hitachi driver. If you're small-handed, you'll love the feel of the smaller grip size. In contrast, RIDGID's R82238 felt the bulkiest of the tools for both my wife and me. 60 April 2009 Woodworker's Journal |
