Short Description

The 100 x 16 mm (4-inch) #80 Grit Fiber Sanding Disc is a durable, medium-grit abrasive accessory designed for an angle grinder, featuring an #80 grit for efficient general smoothing and blending and a rigid vulcanized fiber backing to ensure high durability under operational heat and speed. Its 4-inch size and 16 mm bore offer a standard fit for most small grinders, making it versatile for blending welds, stripping medium rust, and general surface preparation on both metal and wood.

Description
The 100 x 16 mm (4-inch) #80 Grit Fiber Sanding Disc is a versatile and durable abrasive accessory designed for use with an angle grinder. It is made up of durable abrasive particles (like Aluminum Oxide) bonded firmly to a rigid, strong vulcanized fiber backing. The #80 medium grit makes it an excellent general-purpose choice, balancing fast material removal with a smoother finish than coarser discs. It is primarily used for tasks requiring efficient surface blending, such as smoothing down welds, stripping medium amounts of rust and paint from metal, and preparing wood surfaces for final finishing.

Features

 :
  • Fast Cutting Power: It removes material quickly because it uses sharp, durable abrasive grains (like aluminum oxide).
  • Strong and Stiff: The sandpaper is backed by a tough vulcanized fiber (a strong, rigid base) that stops it from tearing apart when spinning at high speeds.
  • Heat Resistant: The grains are secured with a special resin bond that resists heat, meaning the disc lasts longer even when grinding hard metal.
  • Medium Grit: The #80 grit is excellent for general-purpose work—it efficiently smooths surfaces and blends welds, leaving a smoother finish than the #60 grit.

Applications

 :
  • Metal: Blending welds (creating a smooth transition), quickly stripping medium rust and old paint, and preparing metal for a finer finish or primer.
  • Wood: General smoothing and removal of small imperfections from lumber, suitable for preparing surfaces before final sanding. Use gently to avoid burning the wood.
  • General: Removing paint, body filler, or cleaning surfaces that have heavy buildup where a smoother final texture is needed.
Maintenance
  • Dry Storage: Store the discs in a cool, dry place. If the fiber backing absorbs moisture, the disc can warp (curl up), making it unsafe to use.
  • Check for Clogging: If the disc starts slowing down, it's likely clogged with material (called "loading"). Use a sanding belt cleaning stick (a rubber block) while the disc is spinning slowly to scrape the debris off.
  • Inspect Before Use: If the disc has deep cracks, tears, or is badly warped, throw it away immediately and use a new one.

Usage

 :
  • Mount Securely: Always unplug the grinder first! Place the disc onto the grinder's Backing Pad (the rubber/plastic support plate) and tighten the locking nut firmly.
  • Start Away: Turn the grinder on while holding it away from the material and let it get to full speed.
  • Use the Angle: Hold the grinder at a shallow angle (about 10° to 15°) to the metal or wood. If you hold it flat, it will clog and burn.
  • Keep Moving: Use light to medium pressure and move the disc constantly in smooth, overlapping strokes. Never stop in one place, or you will dig a hole or create too much heat.
Precautionary Guidance (Safety Tips):
  • Wear Safety Gear: Always wear safety glasses, a face shield, and gloves. The sparks and dust from this disc can be very dangerous.
  • Check Speed Rating: Make sure the maximum speed rating printed on the disc is higher than or equal to the maximum speed of your angle grinder.
  • Use the Pad: Always use a proper Backing Pad; never attach the disc directly to the grinder spindle without support.
  • Avoid Pressure: Let the tool do the work. Pressing too hard creates dangerous heat and will destroy the disc and potentially damage your grinder.
