Product Description
Compact brushless cordless random orbital sander for convenient one-handed sanding
The ‘20V Max’ 3751 cordless random orbital 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. Our brushless motor is faster, stronger and lasts 10 times longer than a conventional brushed motor. Like all other SKIL ‘20V Max’ cordless tools, this model is powered by the industry-leading PWRCORE 20™ battery and charger technology.
Brushless cordless random orbital sander SKIL 3751 is your ideal partner for sanding both flat and curved surfaces. It offers optimum control during one-handed use because of its extremely compact design and counterweight balancing system ‘VRS’ that reduces vibrations. With its efficient eccentric sanding movements, it’s ideal for both fine finishing and large-scale surface removal. And thanks to the pre-select variable-speed function the speed can be matched to the job. Clean working is guaranteed thanks to the integrated dust suction with micro-filtration system. But if you prefer to use your vacuum cleaner, you can also attach the vacuum cleaner adapter. Another advantage of this model is the integrated brake function, which prevents damage to the workpiece that could arise when placing the tool on the workpiece or removing it. And high-quality dust-sealed ball bearings make sure the dust is kept away from critical internal parts, increasing the tool’s lifetime.
SKIL 3751 CA is supplied with 10 sanding sheets, a micro-filtration dust box and a vacuum cleaner adapter. 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.
