Blue Spot Tools Anti-Clogging Emery Cloth Roll (120 Grit)

MPN: 19904

Barcode: 5028734199048

Size: 3.8cm x 460cm

Weight: 0.14kg

Overview:

This Blue Spot Tools 120 grit emery cloth is coated with aluminium oxide on a J-weight waterproof polycotton backing. It measures 3.8cm x 460cm and includes an anti-clogging design to maintain cutting performance during use.

At 120 grit, this roll sits in the medium range - suited to removing rust, scale, and surface scratches while preparing metal for further finishing. It also works on wood, plastic, and leather. The polycotton backing holds together under both hand and power tool use. The cloth can be used wet or dry and wraps around pipes, rods, and other cylindrical parts.

Key Features and Benefits

• Anti-clogging abrasive: Stays clear during extended intermediate sanding passes, maintaining cutting performance throughout.
• Waterproof polycotton backing: Holds together under the sustained pressure of both hand and power tool use.
• Aluminium oxide coated: Provides consistent abrasion at 120 grit across metals, wood, plastic, and leather.
• Wet or dry compatible: Suits both conditions, with water-assisted sanding available for metal finishing tasks.
• Conforms to curved surfaces: Wraps around pipes, rods, and contoured parts for uniform abrasive contact.
• Hand and power tool ready: Tear or cut to length for use in manual sanding and machine sanding applications.

Specs & Attributes

• Size: 3.8cm x 460cm
• Weight: 0.14kg
• Grit: 120
• Abrasive: Aluminium oxide
• Backing: J-weight waterproof polycotton

Typical Applications

• Removing rust, scale, and surface corrosion from ferrous and non-ferrous metals
• Smoothing scratches left by coarser abrasives during multi-stage sanding
• General surface preparation on metals before painting or coating
• Deburring and cleaning metal edges after cutting or fabrication
• Finishing and polishing brass, copper, and aluminium surfaces
• Intermediate sanding on wood before moving to a finishing stage
• Conditioning plastic and leather surfaces before further treatment

How to Use

• Prepare the surface: Remove any loose particles and confirm coarser sanding stages are complete before starting.

• Cut or tear to size: Take a strip sized for the tool or task at hand.

• Wet or dry: Apply dry for most tasks. Use with water for heat-sensitive metal sanding.

• Keep pressure even: Hold the cloth flat against the surface and work in controlled, consistent strokes.

• Work cylindrical parts: Wrap the emery cloth around the workpiece and draw the cloth back and forth with tension on both ends.

• Check and clear: Stop periodically to inspect the surface and remove any debris from the cloth.

Frequently Asked Questions (FAQs)

• Is 120-grit fine enough to prepare metal for painting?
  120-grit leaves the surface smooth enough for many painting applications, though a final pass with a finer abrasive of 180 or above gives a cleaner result. For automotive or decorative work, finishing with a finer grit reduces visible scratch marks under the coating.

• What does 120-grit emery cloth remove?
  120-grit handles rust, scale, surface corrosion, and old paint on metal. It also removes the scratches left by coarser grits and smooths down rough edges. It strikes a balance between material removal and surface refinement, making it well-suited to intermediate prep stages.

• Can emery cloth remove mill scale from steel?
  Yes. Aluminium oxide-coated cloth at 120 grit cuts through mill scale and surface oxidation on steel. For a very heavy scale, a coarser grit works better for the initial pass, with 120 grit then used to refine the surface afterwards.

• Is emery cloth reusable?
  Emery cloth can be used multiple times, but cutting performance reduces as the abrasive particles wear down. Once it no longer cuts effectively or the surface appears glazed, replace it. Anti-clogging designs help extend usable life by keeping the abrasive surface clear between uses.

• What is the difference between medium and fine grit on an abrasive cloth?
  Medium grit (roughly 80 to 120) removes material and surface scratches more aggressively, leaving a coarser finish. Fine grit (150 to 240) refines the surface further, removing the scratch pattern left by medium grit and preparing it for coating, painting, or polishing.

Summary

The Blue Spot Tools 3.8cm x 460cm 120 Grit Emery Cloth is an aluminium oxide coated sanding roll on J-weight waterproof polycotton backing. The anti-clogging surface and wet or dry compatibility make it a practical choice for rust removal, scale removal, general surface preparation, and intermediate finishing on metals, wood, plastic, and leather.
