TESTS:

Our Tradie used the bench grinder to prepare each end of all pipes for welds to create this exhaust manifold. This involved removing scale and paint and beveling the edges.


SO, WHAT’S THE VERDICT?

PRO’S:

“Overall, this is a good heavy-duty kit. The high guards are worth a special mention, allowing lots of room to work. The

work piece

supports were also really sturdy which is what you want when grinding heavy gauge pipe. The machine is extremely quiet on start-up and the rubber footing definitely reduced vibration throughout the bench – I actually didn’t notice any vibration at all. It is also pretty powerful – I could really load up the grinding wheel.”

“This machine is really about the necessities – it’s not a fancy grinder with lighting, variable speeds or cooling systems, but it’s reliable and does the job. I also noticed the start-up was quick to reach full speed. Overall it was a lot more convenient and safer than hand grinding or torching to prepare for welds.”

CON’S:

“Once I unboxed the kit I noticed there weren’t any bolts to secure the machine to the bench. I know you can’t judge how thick someone’s bench might be, but bolts don’t go astray. An extra journey to the shops could be an inconvenience for some.”

“Usually it’s the machine’s wheels that would cop a go for being wobbly or under-performing, but you can’t make that call until they’re worn in. The only real annoyance I had with the machine is that it was really tedious to realign the guard retaining screws.”

THINGS TO IMPROVE?

“Chuck some bolts in the kit.”

BEST FEATURE?

“Sturdy and zero vibration.”

WOULD YOU BUY IT?

“Yeah! It’s a good mid-range bench grinder and it’s versatile –not too small and not too big. Good for jobs in the shed and on site.”
