Powermatic PM2244 precut abrasive 180 grit is an aluminum oxide sanding abrasive set up for heavy-duty all-purpose sanding, so the abrasive handles a wide range of stock preparation and finishing passes on the PM2244. The aluminum oxide construction provides a consistent cutting action on typical woodworking materials, which helps maintain predictable removal rates across each job. An open coat design gives the abrasive non-loading properties, allowing dust and fines to clear more easily from the surface so the grit stays exposed longer while sanding. This open structure supports longer use between abrasive changes during routine runs. The abrasive is resin bonded for maximum grain retention, so the grit stays anchored to the backing as it cuts, which supports steady performance over the usable life of the strip.
The heavy-duty X weight cloth backing provides a strong base for the abrasive, so it holds up when tensioned on the sander and during repeated passes without easily tearing. This backing strength supports stable tracking and consistent contact with the workpiece, which is important for maintaining even sanding across panels. Resin bonded construction keeps the abrasive grain locked onto this backing as it runs under load, reducing premature grain loss that could otherwise change cut quality mid-run. The anti-static backing helps dust move away from the abrasive toward dust collection, so less loose material stays on the abrasive surface during operation, which supports a clearer sanding interface between the workpiece and the abrasive.
This PM2244 precut abrasive 180 grit is identified for the Powermatic PM2244, so its format and abrasive setup are matched to that sander for heavy-duty all-purpose sanding tasks. The aluminum oxide abrasive works as a general-use cutting surface for wood and similar shop materials, handling routine stock preparation and smoothing between coarser and finer sanding stages. With its open coat design, the abrasive sheds dust more readily from between the grains, which is useful on resinous or dust-heavy woods that tend to clog tighter-coated abrasives. The heavy-duty X weight cloth backing is designed for strength, so it holds together under the PM2244's operating tension and pressure, supporting repeated passes on wide panels or multiple parts in sequence.
The resin bonded abrasive layer provides maximum grain retention on the backing, so the cutting particles remain in place as the abrasive runs, which helps maintain a predictable scratch pattern and sanding rate throughout its service life. Because the abrasive is open coat with non-loading properties, dust and fibers have more room to clear away from the cutting edges, reducing the tendency for the surface to glaze over during extended sanding. This open structure pairs with the anti-static backing, which supports easier dust pickup by dust extraction systems, helping keep both the abrasive and the work surface cleaner as material is removed. The heavy-duty X weight cloth backing resists stretching and tearing under normal sanding pressure, which supports consistent tracking and contact across the width of the workpiece for more uniform results from pass to pass.
The PM2244 180 grit abrasive uses aluminum oxide, providing a consistent cutting surface for heavy-duty all-purpose sanding on typical woodworking shop materials.
The open coat design gives the abrasive non-loading properties, allowing dust to clear more easily from between grains so the abrasive stays effective during longer sanding passes.
The resin bonded construction provides maximum grain retention, helping the abrasive particles stay attached to the backing so cut quality remains more consistent over time.
The heavy-duty X weight cloth backing supplies strength, helping the abrasive resist tearing under sanding pressure and belt tension during demanding or extended runs.
The anti-static backing supports easier dust pickup, helping dust collection remove particles from the sanding area so the abrasive and workpiece stay cleaner in operation.
This 180 grit aluminum oxide abrasive is specified for heavy-duty all-purpose sanding, fitting general stock preparation and intermediate smoothing stages on the PM2244.
The Powermatic PM2244 precut abrasive 180 grit PK/3 combines aluminum oxide grain, open coat non-loading properties, and resin bonded construction to support steady cutting across typical shop runs. The heavy-duty X weight cloth backing adds strength under sander tension, while the anti-static backing aids dust pickup for a cleaner sanding interface. For heavy-duty all-purpose sanding passes on the PM2244, these abrasive details work together to support consistent surface preparation from one workpiece to the next.
