Dewalt DW4312 5 in 8-hole 150 Grit Hook Loop Sanding Discs 25pk

Product Description

The DEWALT DW4312 is a 25-pack of 5-inch, 8-hole, 150-grit hook-and-loop sanding discs designed for use with random orbital sanders. The hook-and-loop backing allows for fast disc changes without tools, keeping downtime low during surface prep work. At 150 grit, these discs fall in the fine range, making them well suited for final smoothing passes on wood, removing light scratches, and prepping surfaces before finishing. The 8-hole pattern supports dust extraction through compatible random orbital sander pads, helping maintain a cleaner work surface and extending disc life.

These discs are used in residential and light commercial finishing applications including cabinetry, trim work, furniture refinishing, and drywall prep. They are a standard consumable for carpenters, finish contractors, and general tradespeople who run 5-inch random orbital sanders as part of their daily workflow. The 25-pack quantity is suited for job-site use where multiple discs are consumed across a single project.

Key Features

• 150 grit fine abrasive for finish sanding and surface prep before coating
• 5-inch diameter fits standard random orbital sander pads
• 8-hole dust extraction pattern reduces loading and improves visibility
• Hook-and-loop backing enables quick, tool-free disc swaps
• 25-pack quantity reduces mid-job restocking

Compatibility

Designed as an OEM-style replacement disc for 5-inch hook-and-loop random orbital sanders with an 8-hole dust extraction pad pattern.

Installation Notes

Always power down and unplug the random orbital sander before attaching or removing a disc. Align the disc holes with the sander pad holes to maintain dust port function. Discs should be replaced when abrasive loading or glazing is visible, as worn discs increase heat buildup and reduce cut quality.
