Does this angle grinder have a speed control feature? If not, which Makita angle grinder does.
Asked by Briansculpt November 15, 20194
AnswersNo it doesn’t
Can you remove the guard?
Asked by Harold November 8, 20195
AnswersYes
Will this accept standard sized wheels or does it need propitiatory disks?
Asked by Harold November 8, 20194
Answers"Thank you for your question. The 9557NB 4-1/2"" Angle Grinder, with AC/DC Switch accepts 4-1/2"" discs with a 5/8" - 11 UNC spindle thread. The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool.
Can you remove the guard to use this as a paint remover or a polisher?
Asked by Harold November 8, 20194
AnswersYou can but it’s up to you But a lot debri everywhere on you and everything around you it’s a risk
is this made in China or Japan?
Asked by Ross August 29, 20193
AnswersA good question. At our local Home Depot they had a single grinder in a box, made in Brazil, for $ 49.00. They also had a twin pack, made in China, for the same money. The one made in Brazil was heavier and appeared to be better made. I bought two of the Brazilian grinders. Not as good as my thirty year old Makita, but I am happy with the purchase.
Can a 5" disk be used with this grinder? Thanks.
Asked by Beck January 25, 20194
AnswersYes, if you use without a guard

May 5, 2020
I picked up this grinder to cut some flagstone I had purchased through a third party. I had to purchase an additional wheel (Ridgid Diamond) because obviously the wheel it came with wasn’t for cutting stone. It works really well. The only issue I have with the grinder is the switch. It’s a little tough switching it on but I believe that’s due to safety concerns. Other than that, it works great. I’ve used it now for about 2 weeks off and on. Great tool to have around for many projects.

March 10, 2020
The only THing wrong I see is the switch, is kind of hard to turn on, need to really use both hands to turn it on, eventually the switch will brake, I had another one before with the same issue. Other than that, very reliable tool.

This is an awesome grinder!
I had used a porter cable angle grinder for a few years around the house and the brushes needed replaced. I ordered another Porter cable grinder (online) took it out of the box and it literally went up in smoke in less than 10 minutes in the middle of my project.
I needed to finish so I walked into home depot and picked this up.
I am so happy I did
So very very smooth with no vibration compared to the Porter Cable units.
I am using to grind floors with a 4 1/2" Dewalt diamond grinding cup and a dust collector attachment.
The only thing is when grinding floors I wish the body was a little longer and thicker. I have big hands and this kinda feels like a kids toy. But it works great.
The slide switch is really easy to use. I am not sure why people have mentioned having trouble getting it to lock on. I had a pc unit that had a paddle switch,,, Ughh - never again . I hate the paddle switch.

Extremely easy to handle and cuts very well. Difficult to make precision cut though, so if it needs to be perfect - don't recommend it. Great for grinding down wood or composite wood (composite fence pieces).
A++ Best Grinder Ever ! !
September 6, 2015
6 years of personal hard use and abuse. Tortured and used just about every weekend. Built two ground up hotrods and many household projects. I was ridiculed for not buying a Dewalt but that same person needed it for a week in the oilfield when his Dewalt died. This grinder has been dropped a few times but always worked. Ground down and cut miles of steel and all metals. The cord never cracked or failed. The grip handle cracked on 6th year but never changed the performance. I disassembled the grinder thinking the bearing failed but it was the ring gear. Sold forever on the grinder. No complaints except it quit working at 10:00 pm on a Saturday night and Home Depot was closed. I'm going to get one after I complete this review.
