Bosch DG300LPD Die Grinder Offers Market Leading Power

We first gave you a glimpse of the Bosch DG300LPD Die Grinder back in February as part of our Bosch 2015 Media Event coverage. For anyone involved with metalworking, the die grinder is a key tool in your arsenal. So what did Bosch do to set this model apart for pros? Let’s take a look.


There are several talking points about the new Bosch DG300LPD die grinder. First of all, they’ve packed a 4.8 amp motor into it. There is going to be a noticeable difference in power compared to die grinders that are in the 3.0 to 4.0 amp range. In fact, Bosch tells us that this model is now the class leader in power.

The new die grinder also benefits from Service Minder carbon brushes. Like all carbon brushes, these need to be changed periodically. Bosch makes it easy to know when you need to change them by automatically shutting off the tool when it’s time. This can seem like a pain when it happens at an inconvenient time, but keeping a spare set of brushes nearby is a relatively small price to pay to keep your tool in service longer.

This model also comes with a no lock-on paddle switch. People will debate their preference of lock on features until the sun goes down. No matter what your preference though, having no lock on is safer in the event that you set the tool down without releasing the lock or you drop it.

“Applications in metal can be tough on a die grinder, especially jobs in tight spaces. Thanks to great power and advancements in ergonomic design, the Bosch DG300LPD Die Grinder can handle deburring and cutting jobs at difficult angles and with limited space. When you’re straining to finish a tough job, a little extra power and a smaller package helps.”

– John Rose, product manager, metal cutting, Robert Bosch Tool Corporation.

Overall, this looks like a great addition to Bosch metalworking tools arsenal.
