3M 7100263903 Deburring Disc 4.5 in Coarse Ceramic

Product Description

The 3M 7100263903 is a ceramic abrasive deburring disc designed for aggressive material removal on metal workpieces. It measures 4.5 inches in diameter and 0.25 inches in height, running at a maximum rated speed of 13,300 RPM. The coarse grade ceramic abrasive construction delivers fast cut rates and consistent performance on edge work, weld cleanup, and surface conditioning tasks. This disc is used by fabricators, pipefitters, and maintenance technicians who need reliable deburring action on ferrous and non-ferrous metals. It weighs 0.04 pounds and ships individually per package.

This deburring disc is suited for use on angle grinders and compatible right-angle disc tools in fabrication shops, job sites, and industrial maintenance environments. It is appropriate for both light production deburring and heavy-edge cleanup applications where a coarse cut rate is required. The ceramic abrasive material holds up well under sustained pressure, making it a practical choice for repetitive deburring passes on cut pipe, plate, and structural steel.

Key Features

• Ceramic abrasive construction for aggressive, fast-cutting deburring action
• Coarse grade for heavy material removal and edge cleanup
• 4.5 inch diameter fits standard angle grinder tool heads
• 13,300 RPM maximum rated speed for compatibility with common 4.5 inch grinders
• Low profile at 0.25 inches height for controlled contact on workpiece edges
• Lightweight at 0.04 pounds for reduced tool fatigue during extended use

Compatibility

Designed as an OEM-style replacement or standard consumable for use with 4.5 inch angle grinders and disc-style deburring tools rated at or above 13,300 RPM.

Installation Notes

Installation and disc changes should be performed by a qualified technician familiar with abrasive tool safety per ANSI B7.1 standards. Always power down and unplug the grinder before mounting or removing a disc. Verify the tool spindle speed rating meets or exceeds the disc maximum RPM before operation. Inspect the disc for cracks or damage before each use and do not exceed the rated maximum speed.
