3M 7000046899 Convolute Deburring Wheel 8 Inch

Product Description

The 3M 7000046899 is a convolute deburring wheel designed for medium to heavy precision deburring, blending, and polishing of metal parts. The wheel binds an open web of abrasive grain and resin to a fiberglass core, producing a strong, dense structure that stands up to aggressive edge work. Fine-grade silicon carbide mineral delivers sharp cutting action and smooth surface finishes. At 8.38 inches in diameter and 3.69 inches wide, the wheel suits bench grinder or pedestal grinder setups in production and job-shop environments. Licensed machinists, tool-and-die technicians, and fabrication shops install and operate this wheel for finishing close-tolerance components.

This deburring wheel is well suited for removing medium to heavy burrs from parts with tight tolerances, including aluminum die cast flashing and similar non-ferrous or ferrous workpieces. The medium-to-hard density construction holds its form against sharp edges without collapsing, while the conformable web follows part contours to reduce gouging on irregular geometry. The open-web structure resists loading, extending the service life of the abrasive across high-volume deburring runs in manufacturing, metalworking, and fabrication applications.

Key Features

• Fine-grade silicon carbide mineral provides sharp cutting action and smooth surface finishes
• Open web, abrasive grain, and resin bonded to a fiberglass core for strength and durability
• Medium-to-hard density stands up to edges and resists deformation under load
• Load-resistant open web prolongs abrasive service life in high-cycle applications
• Conformable construction follows part geometry and minimizes gouging risk
• Effective on close-tolerance parts including aluminum die cast components

Compatibility

Designed as a replacement or standard-supply convolute deburring wheel for bench grinders and pedestal grinders configured to accept 8-inch diameter abrasive wheels.

Installation Notes

Installation should be performed by a qualified operator following the grinder manufacturer's instructions and applicable ANSI B7 safety standards for abrasive wheels. Always power down and lockout the grinder before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and do not exceed the maximum RPM rating marked on the wheel or its packaging. Use proper flanges and blotters as required by the grinder manufacturer.
