Makita 10 Pack - 4.5" Cut Off Wheels For Grinders - Aggressive Cutting For Metal & Stainless Steel/INOX - 4-1/2" x .045 x 7/8-Inch

Q: So what is this 5/8-11 thread. some disks are marked 7/8 while some are 5/8. yet both fit the grinder? can please someone explain?

Excellent Question. 5/8" is the actual diameter size of the spindle found on the angle grinder. Almost every 4 1/2" angle grinders in the US have a 5/8" spindle diameter size. However, on 4 1/2" abrasive discs, the actual diameter of the arbor hole is 7/8". The 2/8" size difference is because of the locking and securing mechanism of both the "Inner Flange" and the "Lock Nut" of the 4 1/2" angle grinder. The Inner Flange and the Lock Nut maintain the stability and safety of the abrasive disc during operation. In other words, your Makita 4 1/2" X 3/64" X 7/8" abrasive disc will properly fit and work on your 4 1/2" X 5/8"-11 angle grinder. Lastly, as a side note, the "-11" refers only to the "Thread Count". "-11" is 11 threads per inch and is standard in the US.

Q: will these cut hardened high speed steel?

Excellent question. These Makita 4 1/2" cutting wheels are engineered to specifically cut Stainless Steel/Inox applications. The "hardness" factor of these Makita 4 1/2" cutting wheels are on the scale of "Very Hard" and would not be recommended for the very hard brittle material of hardened high speed steel applications. Although the Aluminum Oxide material composition of the Makita 4 1/2" cutting wheel may help, it would not hold up very long and would lead to premature wear. In summary, these Makita 4 1/2" cutting wheels are not designed to cut hardened high speed steel, but if you absolutely need to make small cuts, they should be able to get you out of a bind.

Q: before I Purchace will these fit my grinding wheel 5/8 arbor x 4 1/2

Yes, these Makita cutting wheels with 7/8" arbor size fit snugly into all US 4-1/2" Angle Grinders with standard 5/8" shaft diameter

will these cut hardened high speed steel?

before I Purchace will these fit my grinding wheel 5/8 arbor x 4 1/2

So, is this a 5/8 or 7/8 arbor as 7/8 is on the description, but then you say it is optimized for 5/8 arbor? It can only be one.
