4-1/2" x 1/2" x 7/8" Hole EXL Unitized Wheel - 2S Fine (Box of 5)

The method of choice among professionals for new stainless steel work, as well as restoration of old pieces.
With a minimum number of steps, you can use the medium and fine wheels, in sequence, to go from a rough weld to a high degree of polish.
This will minimize the amount of traditional abrasive grinding and shaping, as well as tedious cotton wheel and rouge polishing required to get to a mirror finish.

Although these wheels are avaiable in a range of abrasive grades and densities, the 2A Medium and 2S Fine wheels are the ones most commonly used in the marine industry.

Use a medium wheel for surgically shaping welds.
Use a fine wheel for polishing — use it to make your work appear as though the weld never existed, and the work is all one piece.

Note:  When new, the sharp corner/edge on these wheels can unexpectedly gouge your work.
To avoid this, you can soften the original corner by hand with 80 grit sandpaper (an 80 grit Stikit disc stuck to a workbench works well for this).

• High performance and durability for shaping and polishing stainless steel, as well as deburring and finishing applications
• Smear resistant
• Traditional 1/2" center mounting hole
• Layered unitized wheel construction - abrasive is distributed throughout the structure
• The #2 firmness of these wheels is relatively soft and conformable, like a very heavy felt pad, but still capable of shaping stainless welds
• Abrasive mineral in 2A Medium is aluminum oxide for fast, consistent cutting
• Abrasive mineral in 2S Fine is a fine grade silicon carbide for polishing
• For larger pieces where a thicker wheel is desired, these wheels can be ganged together on your bench grinder


Heavy on the technical side...
How to decipher the grades:
• The leading number is the density or flexibility of the wheel (Range: 2 [soft] — 11 [hard])
• The letter is the mineral type (A = aluminum oxide, S = silicon carbide)
• Abbreviation is the grit (Range: Very Fine — Extra Coarse); not all types of wheels are available in all grits
