The Mirka 23-314-240 Bulldog Gold Linkrol PSA Disc Roll is a 5 inch pressure sensitive adhesive sanding disc roll with P240 grit, built for finish sanding and surface preparation. This is a PSA sanding disc roll designed for finer sanding work on compatible 5 inch PSA sanders and backup pads. Model Number: 23-314-240. If you need a dependable abrasive for smoothing surfaces before the next step, this one is aimed at exactly that job.

What matters here is the combination of disc size, grit, and mounting style. The 5 inch diameter matches a common sander size, while the P240 grit sits in the range where you are refining a surface rather than making aggressive material removal passes. That makes it useful for sanding between coats, final prep before finish, and cleaning up a previous sanding pattern so the surface is ready for paint, stain, or polishing work.

Mirka uses aluminum oxide abrasive on a paper backing in a coated construction. In plain terms, that means you get a familiar sanding feel with good all-around performance for general shop and finishing tasks. Aluminum oxide is a practical choice because it balances cut, durability, and cost well. The paper backing helps keep the disc flexible enough for typical finish work without turning the product into something overbuilt for the job.

The pressure sensitive adhesive backing is the other big point. PSA discs are straightforward: peel, stick, sand. When the job calls for a secure hold on the pad, PSA gives you full-face contact without the extra bulk of hook and loop. That can help with a flatter sanding profile and steady disc support, especially on detail prep and smoother finish passes.

This version uses a no-hole design, so it is intended for setups that do not require dust extraction through the disc. That is worth knowing before you buy. If your sander pad is set up around a vacuum hole pattern, this is not the disc to force into that system. If you run a solid backup pad or a no-hole setup, it is a simple match.

It is sold as a roll pack of 100 discs, which makes sense for users who burn through abrasives regularly and do not want to keep reordering small quantities. That kind of packaging is better for busy finish work, production sanding, and anyone who likes keeping one grit on hand for repeatable prep work.

As part of Mirka's Bulldog Gold series, this disc roll is aimed at users who want dependable sanding performance without getting fancy about it. The value here is not hype. It is a known format, a common grit, and a practical abrasive material in a quantity that works for real shop use.

Who should buy it? Anyone running a 5 inch PSA sanding setup and looking for a finer grit disc for prep and finishing. It makes the most sense for woodworking, paint prep, finishing work, and general sanding where surface quality matters more than raw stock removal. If you need aggressive stripping or heavy leveling, go coarser. If you need a finish-ready refinement step, this grit is right in the zone.
