can i cut door jambs to install flooring?
Asked by Lancer April 11, 20193
AnswersYou probably could, but it would be pretty messy and not too accurate. You can't get the blade flush with the ground because of the guards on both sides, so it'd probably end up with an odd looking angled cut. If you want to cut out the bottom of a door jamb for flooring, I'd use a Makita Multi Tool with a plunge blade on it. The multi tool is also excellent for removing baseboards (something else you'll have to do when installing flooring) as the plunge blade will go through wood as well as the brad nails in baseboards.

Excellent angle grinder
October 11, 2020
I've only used it a handful of times since buying to cut bricks and grind concrete but it's worked great so far. Love the paddle switch, found it easy to use even while wearing thick gloves. Hope to have it for a long time and look forward to using it a bunch more.

April 29, 2019
the only good thing about this grinder is a power cord as it's reusable for something else through pretty expensive piece of cable... used this grinder less the a dozen times cutting aluminum gutters, basically on my first cutoff wheel with about 60% of it left. Rotor winding exploded inside by pulling out magnet wire and shorting it... looks like poor epoxy work as epoxy chipped by commutator area as well...

Absolute Trash!
November 28, 2020
Stopped working after light use cutting a few tiles and 1/8" metal rods. For ~$100, this thing should last a DIYer a lifetime. Instead, it just stops working in the middle of a shower renovation project causing you to stop work and try to fix a tool from a supposedly "quality" brand. Absolutely frustrating! I'm through with Makita and the other "high-end" brands. They charge 3x-10x as much as Harbor Freight and just...break...down! Yet another tool I'll be replacing with a Harbor Freight brand. At least IF they break, I can have another on hand and still spend less for TWO tools than a SINGLE Makita, Bosch (rotary hammers are garbage too!), etc...

Garbage
September 23, 2020
Bought from Home Depot. Used it about 20 minutes. It started smoking, tossed out a piece of copper wire (winding) and started throwing sparks. 20 Minutes! Are you freak'n kidding me?
Switch Problems
August 21, 2020
The switch was always difficult to use. Unfortunately, it now broke off completely. I've had this 16 months, though used it only several times. Unfortunately, the warranty is 12 months.
