I frankly have zero interest in golf, but I did need a portable, light-duty rotary tool for cleaning battery contacts and light buffing, and this one does very well. It runs on disposable AA alkaline batteries rather than a rechargeable battery pack, and I consider that a plus, since it results in lower immediate cost and avoids the irritating self-discharge characteristics and lengthy recharge times of NiCd and NiMH batteries. Torque is limited, but ample for things other than metal grinding or wood routing. It's a useful tool.

The best price I've found for a battery-operated Dremel is the Golf Cleaning Tool Kit. Similar tools, albeit with sanding drum attachments, are sold as "pet grooming tools" and cost significantly more. I use this tool regularly for grinding toenails on my show dogs and find they vastly prefer this battery-operated tool to a corded, electric one. This tool is capable of many traditional high speed/low torque rotary tool tasks.

br /If you're looking for battery powered convenience (4-AA batteries), I highly recommend this two-speed tool. Battery life is reasonable and though the tool is not too cumbersome in the hand for most jobs, if you have a job that requires you to hold it like a pencil it can become a bit fatiguing (it's pretty heavy at the end opposite your work.) The button-lock means you don't have to fool around with small wrenches to tighten or loosen the collett when changing attachments. If you find instances where the convenience of battery operability is of paramount importance, this is a very plausible tool to consider.

Since that there are very few cordless drills made for the hobbyist/modeler, I converted this tool to an excellent drill by replacing the 1/8" collet with a 0" collet, whereas, it will accept #60 thru #80 drill bits. Of course, the low speed of 5,000 RPM may be too fast for plastic or metal, it works great on wood.

You need to look before you leap. Amazon is not, and has not been for a long time, the cheaper buy. Home depot sells this exact same tool for $19.99. Just do a search for Dremel.
