Cordless tool kits: Features that count
These help make cordless kits easier to use
FOR KITS
 |
|
| QUICK ENERGY Ridgid's charger can recharge two batteries at once in half the usual time for smart chargers.
|
|
|
|
Nickel-metal-hydride batteries. Found only on certain models, including previously tested Panasonic drills, NiMH batteries tend to offer longer run time
per charge without toxic cadmium, an environmental disposal hazard. But higher cost has kept their numbers small.
Smart chargers. Found on all tested kits, these charge each battery in an hour or less, vs. three hours or more. Most monitor battery temperature
to prevent overheating; on some models we tested, the charger didn't automatically begin charging batteries that had been
inserted, even though they had cooled. Another kit can charge two batteries at once in just 30 minutes, letting you use and
charge both in rapid succession.
A bright flashlight. All tested kits include a light that uses the kit's battery. Most are incandescent, shine for 3 1/2 hours, and provide good
intensity.
FOR DRILLS
|
|
| HAMMERED Cordless drills with a hammer mode, like those from Porter Cable, pulse as they drill for speedier work through stone.
|
|
|
|
Hammer-drill mode. This provides a back-and-forth pulsing action to help drill through masonry.
Multiple speeds. All tested drills have a slower range for added torque when driving screws and a faster range for drilling holes. Drills
with one range typically sacrifice speed.
Second handle. This attaches to the side of the drill to allow a two-handed grip when driving balky screws or drilling large holes.
Half-inch chuck. Drills with this feature let you use larger bits than you can with a typical, 3/8-inch chuck. Found on almost all models.
FOR SAWS
|
|
| RIGHT BLADE, LEFT BLADE Which side it's on determines where you begin sawing, since the motor and shoe must be over the material being cut.
|
|
|
|
Easy blade change and adjustment. All reciprocating saws we tested allow you to remove and replace the blade without tools. Most also have an adjustable shoe
that lets you expose only part of the blade for tight spots or use unworn teeth when others have dulled. Only a few models
lack blade adjustment. Some models also have tools-free adjustment.
A carbide-tipped blade. All tested circular saws have this feature. A carbide-tipped blade tends to add cutting speed and durability.
Blade position. Unlike corded circular saws, which often have the blade on the right and supporting base or “shoe” and motor on the left,
all of the tested cordless versions except one reverse those positions. Left-bladed saws (above, right), while more comfortable
for left-handed users, could require some reorientation for right-handers, since you must saw from the other side of the board.
But this newer setup tends to make it easier to see what you're cutting by providing a clearer line of sight--good for mouldings
and other details.
