Today we have the Techsouth’s Powerpoint DCS hand-held tungsten grinder.
Much like the Sharpie model tungsten grinders, these are the perfect Pro-Hobby grinders: At a low price point, the Techsouth Powerpoint DCS offers a lot of bang for the buck; and while they’re not as easy to use as the Sharpies, the “DCS” stands for “Dust Collection System”, so this model will limit the users exposure to grinding dust. First off, a favorite feature of all of our users is the size. Just like the Sharpie Grinders, this is truly a hand-held tungsten grinder—and worth noting that it’s the only other grinder that we truly consider “Hand Held”.

Similarly to the Sharpie Deluxe Model, this grinder also has an adjustable grind angle that goes from 15 to 45 degrees. Again like the Sharpie Deluxe, there is no degree scale to let you know exactly what angle you’re grinding. However, you can lock the angle selector so that once you’ve found the angle you want, you’ll get it every time.
Now, breaking from the similarities: the way this unit adjusts isn’t exactly intuitive. The grind angle is adjusted by rotating the dial. So, it was difficult for some of our testers to know whether or not they were increasing or decreasing the grind angle—especially because the grinding chamber is completely enclosed; therefore, you can’t see how the electrode is going to impact the wheel.
The other capabilities shared by the DCS and both Sharpie Tungsten Grinders are: The ability to do a tip flat and notched cut-off. But, this is where we see the one flaw with the dust collection. In order to do a tip flat, or cut electrodes, the grinding chamber enclosure needs to be opened, which then releases the grinding dust into the work area.
A quick note about doing notched cut-off: tungsten is extremely brittle, so ‘snapping’ the tungsten will fracture the electrode and ruin it’s performance. So, if you were to use this wheel to grind completely through the electrodes, the life of the wheel would be shortened dramatically; the compromise here is to score the electrode deeply all the way around; then, use the tip flat holes to finish the job.
Another great feature is the range of electrodes that they cover: From .040” all the way up to 1/8”. Even though they can grind eighth inch electrodes, it puts a pretty good strain on the motor. Also, on the topic of the motor, these do have adjustable speeds, but like all tungsten grinders with adjustable speeds, it should be set to the fastest possible setting. Furthermore, you should exercise patience when the grinder: has low pressure, and is constantly rotating the electrode. This will give you the best finish and it’ll prolong the life of the grinding wheel as well as the motor.
The last topic to note is safety. This unit is fully enclosed, so there is limited exposure to grinding dust and no exposed grinding wheel. And, while we did express our reservations about how well it contains the grinding dust, this unit does meet most job site safety requirements. As for accessories, it’s just the .040” collet, a case, and of course a spare grinding wheel; all of which are included in the Pro-Kit upgrade.
To recap: The Techsouth’s Powerpoint DCS hand-held tungsten grinder cuts, it does tip-flat, it grinds consistently up to eighth inch electrodes, and while it’s not the best at capturing the grinding dust, it does it well enough to meet most safety requirements—which is the main reason why we would recommend it.
