You’ve decided it’s time to upgrade your drill, but how do you know which one to get? Do you prefer a tool with a lot of power that you have to plug in all the time, or do you prefer the freedom and agility of a battery-powered tool? Will you be dealing with wood and drywall, or will you have to punch through concrete and stone? Whatever your requirements, it’s critical to weigh your alternatives and determine which type of drill is best for you. We’ve put together this information to assist you in selecting the ideal drill:
A motor upgrade is also beneficial to many of today’s cordless drills. Brushless motors (as opposed to the more common brushed version) were once only available in contracting firm drills like DeWalt, Makita, and Milwaukee, but today they’re also available in consumer drills from Kobalt, Porter-Cable, and Ridgid. Brushless motors adjust to the degree of resistance they encounter and consume less energy than brushed motors, which run at the same rate whether drilling through a softwood like pine or a hardwood like oak, emptying the battery. They also have less roughness than brushed motors, which allows them to work more effectively. They also have fewer moving components, and since there are no brushes, they never need to be replaced.
Another consideration is the type of handle that will best fit your requirements. T-handles are now standard on most drills to evenly distribute loads, improve balance, reduce slippage, and provide place for a battery. However, if you need to deal with tougher projects or larger screws, you might just want to consider switching to a different kind (like a pistol grip).
Lithium-ion batteries are one of the most common forms of battery today, as they charge faster, last longer, and are lighter than NiCd batteries (Nickel-Cadmium). Lithium-ion batteries likewise discharge at a consistent rate until the battery is totally depleted. Pay attention to two things: the battery charger and the battery’s amperage hour (Ah). Some chargers can recharge a battery in as little as 15 minutes. Others will take three hours, a significant variation that can affect your productivity. Another important parameter that indicates a battery’s storage capacity. A greater Ah figure, once again, indicates a longer battery life.
The majority of cordless drill/drivers have two speed settings: low (about 300 to 400 rpm) for driving screws and high (around 1,200 to 1,500 rpm) for drilling. Electronics in better cordless tools maintain speed under varying loads. A drill/clutch driver’s can be tuned to various levels of resistance to driving force; once that level is reached, the clutch will slip, emit a rapid clicking sound, and stop applying rotational force to the bolt. This prevents the screw from peeling, breaking, or overdriving into the material. A clutch also prevents the motor from overheating when it is subjected to high resistance.
