3M 7000044841 Silicon Carbide Lapping Disc 10 Inch

Product Description

The 3M 7000044841 is a silicon carbide abrasive lapping disc designed for precision polishing and finishing work in the fiber optic and metallurgical industries. The disc features silicon carbide mineral coated onto a 3 mil polyester film substrate with a pressure-sensitive adhesive (PSA) backing for secure, tool-free mounting. The tight particle distribution delivers consistent cut rate, surface finish, and disc life across production runs. At 10 inches in diameter, this disc suits benchtop lapping machines and flat-lap polishing setups used by optics technicians, materials lab technicians, and metallurgical prep professionals.

This disc is commonly used in fiber optic connector end-face polishing and metallurgical sample preparation where controlled, repeatable surface finishes are required. The PSA backing allows fast disc changes on compatible lapping machines and polishing fixtures. Silicon carbide mineral provides aggressive, consistent stock removal on a wide range of materials including metals, ceramics, and optical fiber assemblies. The product line is available in 5.0, 9.0, 15.0, and 30.0 micron grades to support multi-stage polishing sequences.

Key Features

• Silicon carbide mineral on a 3 mil polyester film substrate for dimensional stability
• PSA backing for fast, secure mounting on compatible lapping fixtures
• Tight particle distribution ensures consistent cut rate and surface finish
• Available in 5.0, 9.0, 15.0, and 30.0 micron grades for multi-stage polishing
• Suitable for fiber optic end-face polishing and metallurgical sample prep
• Also available in sheets and rolls for alternate fixture configurations

Compatibility

Designed for use on benchtop lapping machines and polishing fixtures that accept 10 inch PSA-backed abrasive discs, commonly used in fiber optic and metallurgical laboratory applications.

Installation Notes

Mounting is performed by peeling the PSA liner and pressing the disc firmly onto a clean, flat lapping plate or fixture surface. Ensure the lapping plate surface is free of debris and residue before mounting to prevent air pockets that can affect polishing uniformity. Follow equipment manufacturer guidelines for disc speed and applied load. Discs should be inspected before use and replaced when mineral loading or uneven wear is observed.
