Why Choose the Klingspor QRC 800 Very Fine?

The QRC 800 is designed for applications where controlled surface conditioning is required rather than aggressive stock removal.

Klingspor highlights three principal benefits:

• Light deburring

• Removal of rust and paint

• Long service life from the hard, stable surface-conditioning material. (Klingspor)

The Very Fine grade makes catalogue number 295421 particularly useful for final-stage surface refinement and blending where maintaining control over the finish is important.

Very Fine Grade

This version of the QRC 800 is classified by Klingspor as:

Very Fine. (Klingspor)

Very Fine surface-conditioning material is appropriate for applications such as:

• Fine blending

• Refining previously ground surfaces

• Light deburring

• Surface cleaning

• Preparing metal for subsequent finishing

• Producing a more uniform appearance

Unlike a conventional coated abrasive specified by a standard P-grit number, Klingspor identifies this SCM disc by its Very Fine grade.

Blue Colour Coding

Catalogue number 295421 is:

Blue. (Klingspor)

The colour provides a convenient visual identifier for the Very Fine version within the QRC 800 range.

76mm Manufacturer Diameter

The exact Klingspor specification for 295421 is:

76mm Diameter. (Klingspor)

This corresponds approximately to:

3 Inches. (Gasweld)

Some Australian commercial listings describe the product as 75mm, including the Supply Solutions Group listing. The manufacturer's 76mm specification is the more precise technical dimension. (Dicksmith Australia)

Aluminium Oxide Abrasive

The QRC 800 uses:

Aluminium Oxide

abrasive grain. (Klingspor)

Aluminium oxide provides a versatile abrasive action suitable for the metal and surface-finishing applications for which the QRC 800 is designed.

Resin Bond

Klingspor specifies the bonding agent as:

Resin. (Klingspor)

The abrasive grain and resin bond form part of the durable non-woven surface-conditioning construction.

Hard Non-Woven Web Construction

The core of the QRC 800 is formed from a:

Hard Non-Woven Web Material

bonded to a synthetic fibre backing.

Klingspor states that this combination provides the disc with a long service life, while retaining the characteristics needed for surface-conditioning applications. (Klingspor)

Quick Roll Connect System

QRC stands for Klingspor's:

Quick Roll Connect

system.

The QRC connector uses a plastic locking element with a male thread. (Klingspor)

This allows operators to change discs quickly without the more time-consuming mounting process associated with some conventional abrasive products.

Compatible QRC 555 Backing Pad

Klingspor specifies the:

QRC 555 Backing Pad

for use with the QRC 800. (Klingspor)

The backing pad contains the matching mounting system required for the disc's plastic locking mechanism.

The disc should only be used with a compatible backing system and power tool.

Simple Disc Installation

Klingspor's QRC system is designed for straightforward attachment.

The disc is positioned on the backing pad with the fastener facing the pad and then rotated approximately:

180° Clockwise

to secure it. (Klingspor)

This quick-change arrangement makes it practical to switch between abrasive grades or replace worn discs during production and maintenance work.

Light Deburring

Klingspor specifically identifies:

Light Deburring

as a primary application for the QRC 800. (Klingspor)

Typical tasks may include:

• Refining metal edges

• Removing minor burrs

• Cleaning fabricated components

• Finishing areas after cutting or machining

For substantial burr removal or heavy stock removal, a more aggressive abrasive may be required.

Rust Removal

The QRC 800 is also designed for:

Removing Rust. (Klingspor)

Its non-woven construction makes it useful for surface cleaning where the goal is to remove corrosion while conditioning the underlying metal surface.

Paint & Coating Removal

Klingspor specifically lists:

• Paint

• Varnish

• Filler

among the materials/applications suitable for the QRC 800. (Klingspor)

This makes the disc useful for appropriate surface-preparation and maintenance work where old coatings or surface residues need to be removed.

Stainless Steel Applications

The QRC 800 is rated by Klingspor for:

Stainless Steel. (Klingspor)

Typical applications can include:

• Fine blending

• Light deburring

• Surface refinement

• Cleaning

• Weld-area finishing

Where cross-contamination is a concern, abrasives and tools should be managed according to the organisation's stainless-steel fabrication procedures.

General Metal Applications

Klingspor also specifies:

Metals

as a principal application area for the QRC 800. (Klingspor)

The Very Fine grade is particularly appropriate where surface refinement is more important than aggressive material removal.

Hard-to-Reach Areas

One of the main benefits of Klingspor's Quick Change Disc system is its compact size.

Klingspor describes Quick Change Discs as particularly suitable for small and hard-to-access areas on workpieces. (Klingspor)

Applications can include:

• Tight fabricated assemblies

• Small surface areas

• Recessed components

• Localised repair work

• Detailed finishing

• Contoured parts

Backing Pad Selection

Klingspor notes that backing-pad hardness can influence sanding performance.

A hard backing pad supports higher stock removal, while a softer backing pad is better suited to fine sanding and profiled surfaces because it conforms more readily to workpiece contours. (Klingspor)

Backing-pad selection should therefore reflect the required finish and workpiece geometry.

Box of 25

Catalogue number 295421 is supplied in a manufacturer packing unit of:

25 Discs. (Klingspor)

This Supply Solutions Group listing also contains:

25 × Klingspor QRC 800 Very Fine Blue Quick Change Discs. (Dicksmith Australia)

The box quantity is practical for:

• Fabrication workshops

• Maintenance teams

• Automotive workshops

• Manufacturing facilities

• Engineering departments

• Mine-site workshops

• Industrial stores

Related QRC 800 Grades

Klingspor's current data lists the 76mm QRC 800 in:

• Medium – Purple – 295420

• Very Fine – Blue – 295421. (Klingspor)

This allows users to select the grade according to the level of surface conditioning required.

Safety Considerations

Powered surface-conditioning operations can generate:

• Abrasive particles

• Metal debris

• Rust particles

• Paint or coating dust

• Noise

• Heat

Appropriate workplace controls and PPE should be selected according to the substrate, coating and power tool being used.

This may include:

• Safety glasses or goggles

• Face protection

• Hearing protection

• Suitable gloves

• Protective clothing

• Respiratory protection where required

When removing existing paints or coatings, the coating itself should be assessed for hazardous constituents before mechanical removal.

Storage & Handling

For best abrasive condition:

• Store in a clean, dry environment

• Protect from excessive moisture

• Avoid excessive heat

• Keep the non-woven material clean

• Protect the QRC connector from damage

• Keep discs appropriately packaged

• Inspect before use

• Do not use damaged discs

• Use only with a compatible backing pad
