Product Description

‘XP’ brushless cordless angle grinder with ‘VRS+’ side handle
The ‘20V Max’ SKIL 3930 is a powerful cordless angle grinder and part of the SKIL ‘brushless XP’ range. ‘XP’ tools deliver exceptional performance and durability, thanks to their high specifications and advanced digital brushless motors. Like all other SKIL ‘20V Max’ cordless tools, this model is powered by the industry-leading, advanced ‘PWRCORE 20™’ battery and charger technology. Brushless SKIL 3930 is ideal for fast cuts and effortless grinding with its 125 mm disc. A superb innovation is SKIL’s 'VRS+', a superior vibration reduction system compared to traditional systems. A counterweight that can move in all directions is built in the side handle of this angle grinder. This so-called dynamic absorber reduces vibrations to an absolute minimum. And depending on the task at hand, you can easily adjust the side handle into three comfortable positions. The digital brushless motor delivers more power, more efficiency and a 10x longer lifetime than a comparable brushed motor. This cordless angle grinder has an electronic soft start for a gradual run-up to maximum speed without kickback. The ‘Clic’ system allows you to easily adjust the guard without a key, so you can deflect sparks in any desired direction. The SKIL ‘PWRJUMP™’ charger automatically charges your ‘PWRCORE 20™’ battery from 0% to 15% in the first 5 minutes, so you can get back to the job in a flash. The ‘PWRASSIST™’ USB adapter enables charging of mobile devices on the go. The SKIL 3930 DB is supplied in a carrying bag with a 4.0Ah ‘KEEPCOOL™’ battery, a very fast 'Auto PWRJUMP™' 6.0A charger, a ‘PWRASSIST™’ USB charging adapter, one grinding disc and a ‘VRS+’ side handle.

‘PWRCORE 20™’ industry-leading battery technology to power all SKIL '20V Max' tools
The ‘PWRCORE 20™’ system consists of industry-leading advanced battery and charger technology, plus innovative features you won’t find anywhere else, such as our patented ‘KEEPCOOL™’ battery cooling technology which increases the runtime by up to 25% and doubles the battery lifetime. Whereas the patented ‘ACTIVCELL™’ technology safeguards a maximum performance and optimal battery protection. The ‘PWRCORE 20™’ batteries and chargers are 100% compatible and interchangeable with all SKIL ‘PWRCORE 20™’ power tools and garden tools for ultimate flexibility.
