Portable Electric Tools: Rockwell RK1807K2 20-Volt Brushless Drill-Driver And Impact Driver Combo
Rockwell’s new model RK1807K2 20V MaxLithium Drill-Driver and Impact Driver combo with brushless motor technology increases battery run time by up to 50 percent per charge over comparable tools with standard brushed motors.
The brushless motor has computer controlled power distribution, which improves motor efficiency and durability by reducing heat, friction and wear.
Inside Rockwell’s brushless drill-driver and impact driver, carbon brushes have been eliminated to create motors that are maintenance free. The new electrically commutated motors reduce noise, friction, heat build-up and wear for longer motor life.
Precise internal software controls (smart chips) provide the electromagnetic current for the most efficient conversion of electricity into mechanical energy. Since less energy is wasted, battery power lasts longer.
Rockwell’s brushless motors feature a 10-year warranty versus 3 years for brushed motors. Add Rockwell’s Batteries for Life program, once the tools are registered, and the savings is even greater. In fact, over the life of the tool, there’s a cost savings of up to 70 percent versus tool ownership from other manufacturers. Replacement batteries are not cheap and their cost alone should be factored before buying any cordless power tool.
The 20V brushless Drill-Driver is compact and lightweight (3.4 lbs. with battery). Its compact size provides easy access in limited clearance areas. The drill-driver has a short headstock and overmold on the back of the handle for a steady grip. The tool also is equipped with a belt clip for securing the tool when not in use.
The brushless drill-driver is powered by a 20V MaxLithium, 2.0 Ah battery for longer run time and high working efficiency. The battery also affords more charge cycles with minimal self-discharge. The two-speed gearbox has no-load speeds of 0-600 and 0-2000 rpm.
Its maximum torque is 531 in./lbs. The 1/2-inch metal chuck has 18+1 clutch positions to handle a wide range of drilling and driving jobs. The tool’s drilling capacity in wood is 1-1/2 inch and 1/2 inch in steel.
Spring kicks off the deck building season, and an impact driver is indispensable for efficient deck construction. Rockwell’s 20V brushless impact driver with 1550 in./lbs. has plenty of torque to get jobs done fast. This impact driver is a serious deck building and assembly tool. It’s designed to drive screws hard and fast in the densest and thickest materials all day. The tool’s concussions are channeled to the screw, so there’s no residual effect to the user’s wrist or forearm. Its compact size and stubby headstock, affords easy access into limited clearance areas.
It has a 1/4 in. chuck and accepts 1/4-inch hex-shanked bits. The driver has a speed range of 0-2900 no-load rpm and 0-3200 impacts per minute (ipm). The 3.2 lb. impact driver has an LED worklight that doubles as low-battery-charge indicator when blinking. The LED light continues to stay on for a short period after the trigger is released.
There’s comfortable overmold on the back of the handle for a secure grip. The tool also is equipped with a belt clip.
The Rockwell 20V Brushless Drill-Driver and Impact Driver Combo (RK1807K2, $279.99) includes two, 2.0 Ah lithium-ion batteries, a one-hour charger, two, double-ended bits and a soft storage bag.
