Bosch's New GWS Grinders - a Power Tool Spy Exclusive

While we were visiting Bosch last December, we heard a rumour that they had the latest additions to their GWS range of grinders in the building.

Out came our camera and we hastily recorded one of the models being unboxed, plus some fairly staggering spec on how it's going to perform for you.

Check it out.

So, what's new in the range and what's the spec?

There are 3 new GWS models in the range, 2 of which fall into Bosch's "universal" category and come either with or without an anti-vibration side handle as follows:

• Bosch GWS9-115 - 4 1/2" 115mm Angle Grinder with Slim Grip
• Bosch GWS9-115AVH - 4 1/2" 115mm Angle Grinder with Slim Grip and Anti-Vibration Side Handle
• Bosch GWS11-125 - 5" / 125mm Angle Grinder with Slim Grip
• Bosch GWS11-125AVH - 5" / 125mm Angle Grinder with Slim Grip and Anti-Vibration Side Handle

The GWS9 models have a 900W motor and the GWS11 models have an 1100W motor.

Who should be interested in either of these models?

Bosch are aiming these at anyone in the following industries:

• General metal working
• Lock smith
• Plumbing & HVAC installation
• Electrical installation

These grinders are described by Bosch as "the perfect all-rounder for a wide range of applications due to their ideal balance of power and ergonomics". However, it seems to be the perceived lifetime of these new grinders that's causing Bosch to be so excited about them.  This is thanks, in part, to the capability of the brushes, as can be see below (verified by SLG).

Bosch attribute this longer brush lifetime due to the stronger motor and "direct motor cooling'.

Bosch claim, due to these stats, that these new GWS grinders are providing you with the best lifetimes in the market. And the slim grip handle seems to offer a higher level of ergonomics, so going for the version with the anti-vibe handle means you'll be able to use the grinder longer, for longer...

Is there anything a bit beefier on offer?

The two new models we've covered so far are ideal "mini grinders" for universal use, but Bosch recognises that sometimes we need something a bit more powerful. That's why they've added the Bosch GWS12-125CI 5in/125mm Angle Grinder, with around 100W more power than it's predecessor.

It comes with an anti-vibration side handle as standard and features Bosch's well-known Kickback Stop system.

It's aimed at power tool users going for "heavier applications", and it features:

• Heavy duty performance for toughest applications
• Fastest work progress
• Maximum user protection

Who should consider it? Anyone working in the following:

• Metal processing/Steel working
• Machine building/Vessel construction
• Construction
• Roofing

Bosch have piled as much consideration into user safety as they have wattage into the motor.

For example, the GWS 12-125Ci Professional has a large spindle lock, "two-movement safetly-switch protection" to prevent you accidently switching the grinder on, 40% less vibration (thanks to the anti-vib handle), burst-proof guard and Kickback Stop.

So, that's the ever-expanding GWS range of grinders from Bosch.
