DAYUAN 17PC Professional Diesel Injector Seat Cutter Cleaner Tool Set Carbon Remover

good tool works well

Worked great, mabee slightly blunt on the second injector seat cut but still does the job well , saved me a packet of dosh compared to a gar(b)age doing the job, , just make sure its nice and flat clean and shiney down that hole before you put a new copper washer in, then you can't go wrong, great bit of kit.

Very impressed and very good value for money, although you may need to use some tape to allow for a perfect fit where the holder sits inside the injector recess

Good peice of kit bought for my partner as he does all the mechanical bits. He said it worked like a Charm and was happy especially with all the extra add one

Good service

They need an internal thread in back of each cutter. The groove where safety screw bites need to be deeper. Was working on a golf and butter came off deep down in the hole. Had there been a thread in the back I could have lowered a bar with threaded end down and easily got it out. These are good just you should first grind the flat for the safety screw 4 mm deeper

Very good product

Decent kit.. comprehensive cutters for many different engines..offer up cutting socket to the pulled injector to ensure right size and know if injector port base is domed or flat.. Does what it's meant to do in breaking up carbon deposits in port..

Produit conforme à la description, très utile et qui m'a permis d'économiser pas mal d'argent.

Ottimo strumento necessario per fresatura sede guarnizioni iniettori!!!

Seems to be good quality, haven't use it yet.

Funciona bien. Las fresas no cortan mucho pero poco a poco hacen su trabajo. Me ha servido en un motor Mercedes OM646 con la fresa recta de 19x17mm, por si alguien necesita el dato.

Ottimo prodotto
