Zoro Select Flap Disc Type 27 4-1/2" 120 Grit
The Zoro Select flap disc is a coated abrasive wheel built for right-angle grinders. It uses zirconia alumina grain on a plastic backing plate with a threaded 5/8 in.-11 centre hole. The disc is rated for a maximum speed of 13,300 rpm and carries a standard density rating. Trimmable flaps extend usable life during finishing work.
Suited for metal finishing
Fabricators blending weld seams or removing light scale on steel will find the fine 120 grit effective. The Type 27 flat profile keeps the abrasive face parallel to the workpiece. Operators who need aggressive stock removal on curved profiles or a coarser grit for heavy grinding should choose a different disc geometry.
Threaded 5/8 in.-11 centre hole fits common
The connector size matches the spindle thread on many 4-1/2 inch angle grinders. Verify your tool’s arbor specification before purchase. The plastic backing plate and trimmable flaps are designed for standard density applications up to the rated maximum speed.

Questions about this item
Should I choose the 120 grit flap disc or a different grit for fine finishing?
The 120 grit rating provides a fine grade surface preparation suitable for blending and light material removal on metal workpieces.
What does the 13,300 RPM maximum speed mean when mounted on my angle grinder?
Your angle grinder must not exceed 13,300 RPM; operating above this limit can cause the disc to fail and create a safety hazard.
Will the 5/8 In. -11 threaded hole fit my grinder's spindle?
The 5/8 In. -11 threaded hole matches the standard spindle size on most 4-1/2 inch angle grinders for direct mounting.
