Norton 66261183814 Psa Sanding Disc 400 Grit 5 in 100pk

Product Description

The NORTON 66261183814 is a pressure-sensitive adhesive (PSA) sanding disc engineered for finish sanding on wood, composites, and painted surfaces. Part of the Norton A296 series, it uses aluminum oxide abrasive at 400 grit — a super fine grade — bonded to a lightweight B-weight paper backing. The PSA mount attaches directly to a compatible backup pad without hardware, keeping changeovers fast. Rated to 15,000 RPM, this disc is sized at 5 inches in diameter and sold in packs of 100. It is a standard consumable for trades and finishing professionals who run random orbital sanders in production or repair workflows.

This disc is intended for random orbital sander applications where a fine surface finish is required. The 400 grit super fine aluminum oxide is appropriate for final prep before staining or topcoat, light paint scuffing between coats, or smoothing filler compounds. The flexible paper backing conforms to slightly contoured surfaces. No vacuum holes are included, making this disc suited for non-vac backup pads. Cabinet shops, finish carpenters, auto body technicians, and general contractors working on drywall repairs or millwork finishing are typical users.

Key Features

• 400 grit aluminum oxide abrasive — super fine grade for finish-quality surface prep
• Pressure-sensitive adhesive (PSA) backing for tool-free, fast disc changes
• B-weight paper backing provides flexibility on slightly curved or contoured work surfaces
• Rated to 15,000 RPM for safe use on standard random orbital sanders
• No vacuum holes — compatible with solid backup pads
• 100 discs per pack for high-volume production or service use

Compatibility

Designed for use with random orbital sanders accepting 5-inch PSA (adhesive) backup pads. No vacuum holes are present, so the disc requires a solid non-perforated pad. Part of the Norton A296 series.

Installation Notes

Ensure the sander is powered off and unplugged before mounting or removing any sanding disc. Align the disc flush and flat against the backup pad and press firmly across the full face to activate the adhesive bond. Do not exceed the 15,000 RPM maximum speed rating. Worn or contaminated backup pad surfaces reduce adhesion and should be cleaned or replaced before attaching a new disc.
