Mirka Gold 4-1/2-in. x 10-yd. 100 Grit PSA Sanding Roll for Wood and Metal (23-573-100)

The Mirka Gold 23-573-100 4-1/2 in x 10 yd PSA Autokut Roll is a pressure-sensitive adhesive sanding roll made for sanding wood and metal. This is a PSA sanding roll designed for high-speed surface prep and finish sanding. Model Number: 23-573-100. If you want abrasive material you can cut to size for shop sanding, refinishing, or production work, this format gives you flexibility without needing to commit to pre-cut sheets or discs.

The big story here is the combination of size and grit. At 4-1/2 inches wide and 10 yards long, this roll gives you a lot of usable abrasive for repeated sanding tasks. The 100-grit rating puts it in a practical range for general-purpose sanding where you need a solid cut but still want control over the finish. For users working through wood processing, metal processing, or automotive refinishing steps, that balance is usually where a lot of real work gets done.

Mirka positions the Gold line as a durable abrasive suited for high-speed sanding, and that matters more than the label alone. In real use, a durable abrasive helps you keep a more consistent cut across the job instead of swapping material too often. That can save time in production environments and also helps serious DIY users avoid the frustration of abrasive that gives up too early when sanding larger surfaces.

The PSA Autokut format is especially useful when the job does not fit a standard consumable shape. Because the abrasive comes in a roll, you can cut pieces to match the task at hand. That is useful in automotive refinishing, marine work, vehicle manufacturing, and general fabrication where surfaces and sanding tools may vary from one step to the next. It is also a straightforward choice for hand-applied sanding blocks or shop setups that need a custom-cut adhesive-backed abrasive.

Material fit is clear from the product data. This Mirka sanding abrasive is intended for wood and metal, which makes it a practical option for mixed-material shops. If you are moving between wood processing and metal prep, using one abrasive line across both materials can simplify purchasing and keep your sanding supplies more consistent.

Who should buy it? This roll makes the most sense for body shop users, fabricators, marine technicians, woodworkers, and anyone doing repeat surface prep who wants a cut-to-length abrasive instead of fixed-format pieces. If you already know you need a 100-grit PSA abrasive in roll form, the Mirka Gold 23-573-100 4-1/2 in x 10 yd PSA Autokut Roll is a clean, practical pick from a brand that is well known in sanding and finishing.
