Bosch has launched a new line of heavy-duty cordless tools with a battery power system that the company says makes them more powerful than their corded counterparts. The new ProFactor high-powered rotary hammers, grinders and saws pair Bosch’s most powerful lithium-ion battery, the Core 18V, with a new BITurbo brushless motor designed to optimize that battery power for the most demanding jobs.

“It's the part of our tools that produces the high output needed to deliver the corded performance cordless tools so desperately have needed,” said Mike Tsiolis, lead ProFactor marketing manager, during a virtual press event February 9. “Our engineers understood that to deliver serious power on an 18-volt platform, we had to do something drastic.”

The Core18V ProFactor batteries are designed for reduced resistance and greater efficiency, so tools can draw higher currents. The ProFactor batteries come in 8- and 12-amp-hour versions.

Tsiolis says the 8 Ah ProFactor battery provides 75 percent more power and double the runtime than the Core 18V 4-amp-hour battery. He added that though the battery now has ProFactor in its name, it is still compatible with standard 18-volt tools.

The company’s newest battery is a 12 Ah battery exclusively for ProFactor tools. It delivers 50 per cent more runtime than the 8 Ah battery and is geared to heavy-duty tasks.
