Product Description

Compact brushless cordless multi sander for convenient one-handed sanding
The ‘20V Max’ 3720 cordless multi sander is part of SKIL’s compact brushless range. These tools are extremely compact and offer a combination of high performance, durability and an unmatched level of convenience. Like all other SKIL ‘20V Max’ cordless tools, this model is powered by the industry-leading advanced ‘PWRCORE 20™’ battery and charger technology. Our SKIL 3720 brushless cordless multi sander allows you to tackle a wide variety of jobs: from sanding large surfaces and corners to sanding even the most hard-to-reach areas. The ergonomic, extremely compact, lightweight design makes this tool ideal for one-handed and vertical use. Exquisite test results of the SKIL 3720 show a very long runtime: over 50 minutes with a 2.5Ah battery and over 100 minutes with a 5.0Ah battery (tested on pine wood with sanding paper grit 120, applying 3 kg of weight). The patented internal set up with ‘VRS’ for extremely low vibrations enables continuous work for an extended duration, without fatigue. Supplied with extra attachments for sanding in narrow spaces and a unique flexible attachment that adapts to all kinds of round shapes, this powerful multi sander handles your sanding jobs with ease. And changing these attachments is also very easy thanks to the ‘Clic’ system, which doesn’t require any special tools or keys. The digital brushless motor delivers more power, more efficiency and a 10x longer lifetime than a comparable brushed motor. The high-quality dust-sealed ball bearings make sure the dust is kept away from critical internal parts, increasing the tool’s lifetime. The SKIL 3720 CD is supplied with a turnable delta tip, three special sanding attachments, 24 sanding sheets and a dust bag. The battery and charger aren’t included.

‘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.
