SurfPrep 5 inch 400 grit sanding disc describes a SurfPrep abrasive disc with a 5 inch diameter and a 400 grit rating, which supports fine sanding where a smooth surface is needed before further finishing steps. The disc uses aluminum oxide abrasive, which provides the cutting action that levels and refines surfaces in woodworking or similar shop work. This sanding disc is built on a film backing, which holds the aluminum oxide layer and maintains disc shape while sanding flat areas or profiles. A 6 hole layout is part of the design, giving a consistent pattern that works with matching vacuum-hole pads to draw dust away from the sanding face. The disc is silver in color, which helps quickly identify this specific SurfPrep abrasive among other grits or types on the bench or in storage.
This SurfPrep aluminum oxide sanding disc relies on its 5 inch size to match common random-orbit style sanders that use hook-and-loop type abrasive discs, allowing straightforward disc changes during sequences of sanding steps. The 400 grit specification defines how fine the scratch pattern is, which matters when moving from more aggressive cutting toward surfaces prepared for subsequent finishing work. Aluminum oxide abrasive on the working face provides the cutting and leveling effect, which helps users bring uneven or marked areas to a more uniform condition. The film backing under the abrasive keeps the disc flat and stable so the abrasive layer can stay in consistent contact with the workpiece as the sander moves. The 6 hole pattern connects to dust-collection style pads that share the same hole layout, giving a pathway for dust to move away from the sanding interface.
The SurfPrep 5 inch 400 grit 6 hole aluminum oxide sanding disc on film, silver, is positioned for tasks where fine surface preparation is needed after coarser grits have already shaped the work. The 5 inch size aligns with sanders designed for that diameter, so the disc covers a practical area on cabinet doors, drawer fronts, and similar parts while remaining easy to control. At 400 grit, the abrasive surface refines the prior scratch pattern to a finer level, supporting smoother surfaces before any later finishing work. The aluminum oxide abrasive provides the cutting face that contacts wood or other materials, allowing the disc to knock down minor high spots or remaining marks from previous sanding steps. The film backing holds this abrasive layer steady across the face of the disc, which helps keep the contact even as the pad travels over flat sections or gentle contours.
This SurfPrep film backed sanding disc uses its 6 hole configuration to align with sanding pads that share the same hole pattern, giving a route for dust to move away from the work surface while the sander is running. That alignment helps keep the abrasive surface clearer, so the 400 grit aluminum oxide continues to cut in a predictable way rather than riding on loose dust. The 5 inch diameter of the disc matches tools built for that size, which supports repeatable coverage patterns and makes it easier to use standard sanding routines across multiple pieces. With its silver color, this SurfPrep abrasive disc remains easy to distinguish from other grits or disc types stored nearby, which reduces handling errors when moving between sanding stages. The combination of aluminum oxide on a film backing and the defined 400 grit rating works together to give a consistent fine sanding action, allowing the user to build reliable surface quality from piece to piece.
The SurfPrep SP5HLF400.6 is a 5 inch 400 grit 6 hole aluminum oxide sanding disc on a film backing, silver in color, which positions it for fine sanding work.
The 5 inch diameter matches sanders built for 5 inch discs, giving a balance between coverage and control on parts like cabinet doors and panels.
The 400 grit rating places this disc in the fine sanding range, so it refines surfaces after coarser sanding to prepare them for later finishing stages.
The aluminum oxide abrasive provides the cutting surface that levels and smooths material, helping create a more uniform finish during sanding.
The 6 hole configuration aligns with compatible pads so dust can move through the holes away from the sanding face, supporting clearer abrasive contact.
The film backing supports the aluminum oxide layer and helps keep the disc flat, which promotes even contact and consistent sanding results across the surface.
The SurfPrep 5 inch 400 grit 6 hole aluminum oxide sanding disc on film, silver, combines size, grit, abrasive type, and backing into a setup oriented toward fine surface preparation work. The 5 inch diameter fits sanders designed around that disc size, so it works naturally into workflows that already rely on 5 inch tools. With its 400 grit rating and aluminum oxide abrasive, this SurfPrep disc focuses on refining surfaces after earlier sanding passes. Selecting this SP5HLF400.6 SurfPrep sanding disc aligns the 6 hole layout, film backing, and fine grit into one abrasive choice for controlled, repeatable sanding.
