3M 7010329608 Scotch-brite Unitized Wheel 4 in 1/4 in Arbor

Product Description

The 3M 7010329608 is a Scotch-Brite Cut and Polish Unitized Wheel designed for aggressive deburring, blending, and finishing on harder metals. Measuring 4 inches in diameter with a 1/4-inch arbor, this tightly layered, non-woven wheel delivers consistent abrasive action throughout its usable life. It is built for applications where portability matters and where small diameter and narrow width are required. Machinists, fabricators, and metal finishing technicians reach for this wheel when working on stainless steel, carbon steel, and high nickel alloys that demand controlled, repeatable surface work.

This unitized wheel fits grinders and rotary tools used in metal fabrication shops, maintenance environments, and field service applications. Its compact 4-inch diameter makes it well suited for tight access areas and portable tool use. The wheel handles deburring of cut edges, blending of welds, and surface finishing passes on harder alloy workpieces. It is available as an individual unit and is commonly used where consistent finish quality across multiple passes is required.

Key Features

• Tightly layered unitized construction runs in clockwise or counterclockwise directions for flexible tool mounting
• High concentration of aluminum oxide abrasive mineral cuts aggressively and produces a bright finish throughout wheel life
• Non-woven flexible construction delivers controlled abrasive action that resists undercutting and gouging
• Scotch-Brite material resists loading and wears at a uniform rate for continuous cutting action
• Suited for deburring, blending, and finishing on stainless steel, carbon steel, and high nickel alloys
• Compact 4-inch diameter supports portable tool use and access to confined work areas

Compatibility

Designed for use with rotary tools and angle grinders fitted with a 1/4-inch arbor. Suited for metal finishing applications on harder metals including stainless steel, carbon steel, and high nickel alloys.

Installation Notes

Installation and wheel mounting should be performed by a qualified operator familiar with abrasive wheel safety. Confirm the tool spindle speed rating does not exceed the maximum rated RPM of the wheel before mounting. Power down and unplug or lock out the tool before changing wheels. Inspect the wheel for damage before each use and never use a wheel that shows cracking, delamination, or uneven wear.
