SIA 115mm (4.5") Grinding Discs Grit Level = P40 Economy Flap Disc - pack of 10

SIA make their top quality Flap Disc available in all 3 life lengths, economy, standard and jumbo (longest life) they all enjoy the same quality of bonded grinding media just the number of leaves changes with "Jumbo" having the most and lasting the longest, followed by the "standard" range which enjoys the widest range of grit levels, this is followed by the "economy" flap discs with the least amount of leaves - still better than the cheap discs on the market.  The economy range makes sense to purchase when you know you cannot avoid having to run the working edge into an item which can cause premature degradation of the outer grinding edge.

All Sia's products are produced to the highest quality and their flap discs are made in their own factory in Switzerland. Not only does this mean you get the highest quality abrasive you get it consistantly from one pack to the next. 

Perfect on mild steel for dressing welds and smoothing edges prior to painting. You can also use them for cleaning up your metal before welding. An excellent multi-purpose disc. 

These discs come with a 22mm centre to fit any standard 4.5 inch grinder.
