Description
The Dremel 8240 is a compact 12V cordless rotary tool that gives you the freedom to work anywhere, supplied here as a ready-to-use kit with a 2Ah battery, charger and a 5-piece accessory set. Dremel says it delivers the same power as its corded 4250, without the need to stay near a power point, so it suits hobbyists, DIYers and tradies who want a small, capable tool for detail work around the home, workshop or garage.
About the product
The 8240 runs on a removable 12V, 2Ah lithium-ion battery for a good run time between charges. Dremel has tuned it to run cooler and quieter than the earlier 8220, so it stays comfortable over longer sessions. The soft grip and thumb-position speed control are designed for easy handling. A motor brake stops the rotation straight away when you switch off, which helps with control and safety. LED battery indicators show the remaining charge at a glance. A hanger bail lets you hang the tool from a Dremel tool holder with a Dremel Flex-shaft.
Where to use it
Indoors: craft and hobby projects, model making, engraving, sanding and polishing small items, and tidy-up work around the home.
Outdoors and in the workshop: cutting, grinding, carving and sharpening jobs where a power point is not handy.
How to use it
Fit the supplied battery, choose an accessory suited to your job and set the speed with the control under your thumb. The tool is compatible with the full range of Dremel rotary attachments and accessories, including Dremel MAX accessories and the EZ Lock system, which uses a pull, click and twist action to change accessories quickly. It is suited to cutting, grinding, carving, engraving, sanding, cleaning and polishing.
