3M 7000047129 Convolute Deburring Wheel 8 Inch

Product Description

The 3M 7000047129 is a convolute deburring wheel built for medium to heavy precision deburring, blending, and polishing on metal and machined parts. The wheel bonds an open nylon web loaded with silicon carbide abrasive grain and resin to a fiberglass core, producing a strong, dense structure that holds up under sustained edge work. At 8 inches in diameter and 4.69 inches wide, this wheel fits standard bench grinder and pedestal arbors used in production and job shop environments. Silicon carbide mineral delivers sharp cutting action with smooth finish results on a range of base materials.

This deburring wheel is suited for production deburring and finishing operations on aluminum die cast components, machined steel, and other precision parts with close tolerances. The open web construction resists loading, extending service life in high-volume deburring cycles. Its conformable structure allows the wheel to follow part geometry, reducing the risk of gouging or unwanted material removal on contoured surfaces. Machinists, tool-and-die technicians, and metal fabricators typically use this wheel in shop-floor finishing operations.

Key Features

• Silicon carbide abrasive grain delivers sharp cutting action and smooth surface finishes
• Medium to hard density construction stands up to edge deburring on close-tolerance parts
• Open web design resists loading and extends abrasive service life
• Conformable wheel follows part geometry to reduce gouging risk
• Fiberglass core provides structural strength for sustained use at rated speeds
• Effective on aluminum die cast flashing, machined steel, and similar workpiece materials

Compatibility

Designed for use on standard bench grinder and pedestal grinder arbors that accept 8-inch diameter convolute deburring wheels. Verify arbor bore size and maximum rated speed before mounting.

Installation Notes

Mounting and operation of abrasive wheels should be performed by qualified personnel following ANSI B7.1 safety requirements for the use, care, and protection of abrasive wheels. Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel visually for cracks or damage before each use and never operate above the maximum RPM rating marked on the wheel. Eye protection and appropriate PPE are required during operation.
