Dynabrade 320 grit sanding sheet is a hook and loop aluminum oxide abrasive on C-weight paper in a 3 inch x 4-5/16 inch size, so it supports controlled sanding passes on compact surfaces where precise work is important. The 320 grit rating defines it as a fine abrasive, which helps when a smoother finish is needed after coarser sanding stages. The sheet is described as general purpose production paper, so it fits routine sanding tasks in production settings where consistent performance across multiple parts matters. Aluminum oxide as the abrasive material delivers a cutting action suited to light de-burring tasks, so small burrs can be knocked down without overly aggressive stock removal. The C-weight paper backing gives the sheet body for flat support, which helps the abrasive stay in contact across the work area during light scouring or finishing steps.
This Dynabrade hook and loop sanding sheet is sized at 3 inches by 4-5/16 inches, so it fits sanding pads and tools configured for that footprint in shop or onsite work. The hook and loop backing style engages with matching hook and loop pads, which lets the user press the sheet into place without adhesives and remove it by peeling, helping maintain a steady pace when moving between grit levels. The 4-hole pattern is designed to align with compatible 4-hole pads, so when a dust collection system is in use the holes give a path for material to move off the work surface. With a 320 grit aluminum oxide abrasive on C-weight paper, the sheet supports light de-burring and scouring where a more refined surface is needed while still allowing a stable, flat sanding action.
This Dynabrade 320 grit hook and loop aluminum oxide sheet, in its 3 inch x 4-5/16 inch format, fits sanding tools built for that pad size in cabinet, millwork, or other shop environments that use compact pads around this footprint. The general purpose production paper description aligns with routine sanding sequences where parts move through repeated steps and a fine grit is needed for later passes. Because the abrasive is aluminum oxide on a C-weight paper backing, it supports light de-burring work on edges and profiles where a solid paper base helps keep the abrasive face even. The 4-hole layout integrates with 4-hole hook and loop pads that route dust through the pad face, so on systems built around that configuration the sheet becomes part of a controlled surface prep workflow. In practice this makes the sheet suited to fine passes after shaping, or scouring where a consistent scratch is required.
The specified 320 grit level gives the Dynabrade sheet a defined place in a sanding sequence, so users can move from coarser abrasives down to this grit when they want surface refinement without jumping to ultra-fine levels. The combination of aluminum oxide abrasive and C-weight paper means cutting action is balanced with backing stiffness, so the sheet resists folding excessively while still conforming enough for general purpose work. The hook and loop backing directly affects workflow because the sheet can be removed and repositioned on a matching pad, supporting quick grit changes during production runs where downtime between steps matters. The 3 inch x 4-5/16 inch dimensions ensure the contact area stays manageable on smaller workpieces or localized repair areas, which aids control over pressure and scratch direction. The 4-hole configuration gives a fixed pattern for pads designed around four-hole dust extraction, so alignment is predictable each time a new sheet is mounted.
The Dynabrade 320 grit hook and loop sheet is described as general purpose production paper and is used for light de-burring and scouring, so it suits fine sanding tasks in ongoing shop workflows.
The Dynabrade sheet uses hook and loop backing, so it attaches to compatible pads by pressing it on and peels off for removal, allowing quicker abrasive changes between sanding steps.
The 3 inch x 4-5/16 inch size keeps the Dynabrade sheet compact, which aids control on smaller surfaces, edges, or detailed areas when using tools designed around this pad footprint.
This Dynabrade sheet uses aluminum oxide on C-weight paper, giving a fine cutting surface supported by a firm backing, which helps maintain a flat scratch pattern during light de-burring.
The Dynabrade sheet has a 4-hole layout that matches 4-hole hook and loop pads, so in systems using those pads the holes offer a path for dust to move through the pad face.
Dynabrade part number 93893 designates this specific 320 grit, 3 inch x 4-5/16 inch, 4-hole hook and loop aluminum oxide sheet on C-weight paper for general purpose production use.
The Dynabrade 320 grit hook and loop aluminum oxide sheet on C-weight paper, in the 3 inch x 4-5/16 inch 4-hole format, brings together a defined fine grit, a stable backing, and a production-focused design. For shops using hook and loop pads and looking for a general purpose production paper that handles light de-burring and scouring, this sheet offers a size and hole pattern aligned with 4-hole systems built around that footprint. Choosing this Dynabrade 93893 abrasive lets the sanding step slot into a repeatable workflow where controlled, fine surface preparation is needed.
