3M 7100331727 Cubitron 3 Quick-change Disc 36 Grit 2 in 50PK

Product Description

The 3M 7100331727 is a Cubitron 3 quick-change abrasive disc engineered for aggressive material removal on stainless steel, nickel alloys, cobalt, Inconel, titanium, and chrome. The disc uses a closed-coat ceramic abrasive on a YF-weight polyester cloth backing with a TR-style quick-change attachment. Ceramic grain self-sharpens continuously during use, sustaining cut rate longer than conventional abrasives. An additional coating reduces surface temperatures during grinding, making this disc well-suited for heat-sensitive alloys where thermal discoloration or work hardening is a concern. Each pack contains 50 discs at 36 grit.

This disc is sized at 2 inches and is designed for use with TR quick-change disc tools commonly found in metal fabrication shops, aerospace maintenance environments, and industrial maintenance operations. Typical applications include weld blending, edge deburring, and surface conditioning on stainless steel and exotic alloys. The closed-coat construction delivers a smoother finish and faster stock removal compared to open-coat alternatives. The flexible cloth backing conforms to contours and resists tearing under aggressive grinding conditions.

Key Features

• Ceramic abrasive self-sharpens continuously for sustained cut rate and longer disc life
• Additional coating minimizes heat buildup, protecting heat-sensitive alloys from discoloration and work hardening
• Closed-coat coverage across the full disc surface for faster material removal and smoother finish
• YF-weight polyester cloth backing is flexible, tear-resistant, and conforms to contoured workpieces
• TR quick-change attachment for fast disc swaps without tools
• Suitable for stainless steel, nickel alloys, cobalt, Inconel, titanium, and chrome

Compatibility

Designed for use with TR-style quick-change disc tools. Compatible workpiece materials include stainless steel, nickel alloys, cobalt, Inconel, titanium, and chrome.

Installation Notes

Installation is performed by metalworking and fabrication professionals using TR quick-change disc grinders. Ensure the backing pad is rated for the disc diameter and RPM before mounting. Inspect the disc for damage before each use and do not use damaged or delaminated discs. Follow applicable ANSI B7.1 and tool manufacturer safety guidelines for abrasive disc operation, including proper guard installation and appropriate PPE.
