*Grinding wheel dimensions: outer shape 100 / thickness 3.5 / inner diameter 15 (mm)

I found this Angle Grinder in the recycling power tools station. I liked the unique design of HITACHI Power tools and I bought it for only ~$8 with some missing parts. I found out that they built their version of A/Grinder in this style round 2005, now under HiKOKI. It almost had no damage in Armature/Field Assembly, but it was very dirty and had a lot of dust (Cement) that make it stuck when turn on, also switch was broken from my first look. I used few version Angle Grinder before but for me this version really good design and power (quite Hot), I'm very happy how it turned out and I really like it new look. I'll keep this A/Grinder in my workshop and I'm going to use it from now, you will see it often in my next videos.

If you have any questions about my used techniques, my mistakes during restoration, please let me in the comments. I am no professional, I'm always learning, looking for new methods and trying to improve my skills, so please give me some feedback, constructive criticism and suggestions. My technical English is by far not the best, I learned it during my offshore life and just for work.

This is my first video, so i'm sorry for the bad quality, HD but only in 24 frame/sec, sorry make mistake about record video setting , i will improve quality, color, brighten by editing software in my next videos.

I hope you will become my subscriber, every comment is highly appreciated. Once again Thank for watching !
