3M 7010307647 Lapping Film Disc 4 in Silicon Carbide

Product Description

The 3M 7010307647 is a pressure-sensitive adhesive (PSA)-backed lapping film disc designed for fiber optic connector polishing and other precision finishing applications. The abrasive mineral is silicon carbide, coated onto a 3 mil polyester film backing. This combination delivers a consistent cut rate, predictable finish quality, and stable service life across repeated use. At 4 inches in diameter, the disc mounts directly to a backing pad without adhesive preparation. Fiber optic technicians, optical assembly shops, and precision finishing operations are the primary users of this product.

This disc is used in fiber optic polishing workflows where tight particle distribution is required to achieve repeatable connector end-face finishes. The PSA backing allows fast disc changes on compatible rotary polishing fixtures. It is suited to both single-mode and multimode connector termination processes in telecommunications, data center, and industrial fiber installation environments. The silicon carbide mineral is appropriate for polishing ferrule materials commonly encountered in fiber connector assemblies.

Key Features

• PSA backing for quick, tool-free disc mounting and removal
• Silicon carbide abrasive on a 3 mil polyester film for dimensional stability
• Tight particle distribution for consistent cut rate and finish quality
• 4-inch diameter fits standard lapping and polishing fixtures
• Sold individually; minimum order quantity is 1000 units

Compatibility

Designed as an OEM-style replacement lapping disc for use with rotary fiber optic polishing fixtures that accept 4-inch PSA-backed abrasive discs.

Installation Notes

Fiber optic technicians and precision assembly personnel typically handle installation of lapping film discs. Ensure the backing pad surface is clean and free of debris before applying the PSA disc to prevent uneven contact. Disconnect and properly store any live fiber connections before beginning polishing operations. Follow equipment manufacturer guidelines for rotary speed and polishing sequence when using lapping films.
