Good Vibrations? Review of the Metabo WEA14-125 Quick Angle Grinder
Posted by Mark Hunter - April 03, 2013
It's the law. You must reduce the amount of vibration you're exposed to each day on the job site. That means if you use power tools that produce vibration you need to spend less time using them. Which means jobs are going to take you longer to complete. It's either that or get white finger...And no one wants white finger.
In truth, there's no such thing as good vibrations on the job site, so we need to take a close look at the power tools in our kit to make sure we're within the daily limits of hand-arm vibration as laid out by the Health and Safety Executive.
In this review, we'll be looking at what Metabo are doing in their grinder range to make sure you - and your employer - are staying within the safety limits.
Metabo have launched the Metabo WEA14-125 Quick. It's a 1400W, 125mm (5") angle grinder that's unique selling points include the low levels of vibrations it produces.
Metabo claims 3.6m/s≤ which it says is down from "the already low" 6.5m/s≤.
What makes it possible to provide such a low hand-arm vibration reading is a fairly simply modifcation to the grinder in the form of an autobalancing nut. We asked Metabo's Kyle Leitch to explain - and demonstrate - how this works.
Essentially, Metabo have placed the autobalancing nut between you and the "business end" of the grinder, thereby significantly reducing the amount of vibration that reaches your hands and arms. In the real world, this low vibration reading translates to up to 15 hours a day working time before you reach the Health and Safety Executives recommended ELV (Exposure Limit Value).
Which is fantastic, if you want to work 15 hours a day... But, let's image you do, with the WEA 14-125 Quick you'll have peace of mind.
But what about the performance of the WEA 14-125 Quick asides from vibration control?
Outputing 3.3Nm of torque from the 1400W motor, the WEA 14-125 Quick is going to give you RPMs of between 7000 and 10500. The RPMS are controlled via Metabo's "Vario Tacho Constamatic" (VTC) full-wave electronics, sort of like cruise control in your car. The 1400W motor is Metabo's fabled "Metabo Marathon Motor" kind, so you can expect it to run and run and run...and this is aided by Metabo's excellent dust-protection technology and overload protection.
The spindle features an M14 thread with a quick-change nut system which is tool-free.
The gear housing is die cast aluminium which helps protect and lengthen the lifespan of the gear box along with Metabo's S-automatic torque limiting clutch, and the vibration control is extended to the handle of the grinder, which features Metabo's "VibraTech" dampening design.
All in all, this is the sort of power tool we expect to see Metabo manufacturing. It's rock solid, bullet-proof, it'll run and run, and thanks to the autobalancing nut and VibraTech handle, you'll be able to let it run and run while staying within the vibration health and safety limits.
So, are you ready to trade your grinder in for some good vibrations from Metabo? Let us know what you think of the WEA 14-125 Quick in the comments.
