125mm × 32mm 4A2 Diamond Grinding Wheel for Circular Saw Blade Sharpeners – VEVOR, Holzmann, Güde & Compatible Machines

Upgrade or replace the grinding wheel on compatible circular saw blade sharpening machines with this 125 mm × 32 mm 4A2 resin-bond diamond grinding wheel, designed for sharpening tungsten-carbide-tipped (TCT) circular saw blades.

This wheel is intended for professional and workshop sharpening applications where a 125 mm outside diameter and 32 mm bore are required. The 4A2 dish-style profile provides the geometry needed for controlled contact with carbide saw teeth while maintaining a clean sharpening edge.

It is suitable for use with selected VEVOR, Holzmann, Güde and other circular saw blade sharpeners that use the same wheel size and spindle configuration.

Product Specifications

Designed for Carbide-Tipped Saw Blades

This wheel is specifically intended for sharpening tungsten-carbide-tipped circular saw blades.

Diamond abrasive is highly effective for grinding carbide because it provides:

• controlled material removal

• consistent sharpening performance

• improved edge finish

• longer abrasive life

• reduced wheel wear compared with conventional grinding abrasives

The 4A2 dish profile allows the grinding surface to reach individual carbide teeth at the sharpening angles required by compatible circular saw blade sharpening machines.

Compatible Machine Types

This wheel is intended for sharpeners that use:

125 mm grinding wheel diameter
32 mm centre bore
4A2 or compatible dish-style grinding wheel profile

Potential compatible machine families include selected models from:

• VEVOR

• Holzmann

• Güde

• Generic JMY8-70 / MTY8-70-type circular saw blade sharpeners

• Other professional circular saw blade sharpening machines using 125 mm × 32 mm grinding wheels

VEVOR Compatibility

This wheel is intended for VEVOR JMY8-70 / 370W-type circular saw blade sharpeners and other VEVOR machines using a 125 mm wheel with 32 mm bore.

VEVOR has produced several different sharpener configurations, so customers should verify their original grinding-wheel dimensions before ordering.

Holzmann Compatibility

Suitable for compatible Holzmann circular saw blade sharpeners using a:

125 mm outside diameter × 32 mm bore wheel

This may include machines in the MTY8-70 family, subject to verification of the original wheel dimensions.

Güde Compatibility

Suitable for compatible Güde sharpening machines using a:

125 mm outside diameter × 32 mm bore grinding wheel

This may include selected GSS 500 / GSS 700P-type machines, subject to verification.

Important Compatibility Notice

Please verify your machine before ordering.

Circular saw blade sharpeners from the same manufacturer may use different grinding-wheel sizes, bores and profiles.

Before ordering, check:

1. Machine model number

2. Original grinding-wheel diameter

3. Centre bore diameter

4. Grinding-wheel profile

5. Original wheel width/thickness

Your machine should require approximately:

125 mm outside diameter × 32 mm centre bore

Do not order based only on the machine brand.

A VEVOR, Güde, Holzmann or other branded sharpener may use a different grinding-wheel size depending on the model.

Not Suitable For

This wheel is not intended as a direct replacement for:

• sharpeners using a 100 mm / 4-inch grinding wheel

• machines requiring a 20 mm bore

• machines requiring a 13 mm bore

• general tile-cutting machines

• masonry cutting tools

• handheld diamond cutting applications

• ordinary abrasive cutoff saws

This product is a precision sharpening wheel, not a general-purpose diamond cutting disc.

Recommended Grit

180 Grit – Standard Sharpening

We recommend 180 grit for general-purpose use.

This provides a good balance between:

• carbide material removal

• sharpening speed

• surface finish

• tooth-edge quality

Optional Grits

Depending on availability, other grit sizes may be offered:

120–150 grit

• faster stock removal

• useful for damaged or heavily worn carbide teeth

180 grit

• recommended for general sharpening

• good balance between removal rate and finish

320 grit

• fine finishing

• suitable for light sharpening and final edge finishing

Contact Tend Industrial Supplies if you need a specific grit.

Typical Applications

Suitable for:

• circular saw blade sharpening shops

• woodworking shops

• cabinet-making facilities

• sawmill maintenance departments

• metal fabrication workshops

• industrial maintenance facilities

• professional tool sharpening services

• contractors maintaining carbide saw blades

• replacement parts for imported sharpening machines

Why Choose a Resin-Bond Diamond Wheel?

Resin-bond diamond wheels are widely used for precision carbide grinding because the bond provides controlled cutting action while maintaining a consistent abrasive surface.

Benefits include:

• excellent carbide grinding performance

• reduced heat generation

• good surface finish

• controlled tooth geometry

• improved grinding efficiency

• long wheel life

• suitable for precision sharpening applications

Installation Guidance

Before installing the replacement wheel:

1. Disconnect the sharpening machine from electrical power.

2. Remove the existing wheel according to the manufacturer's instructions.

3. Inspect the spindle, flange, and retaining components.

4. Confirm the machine spindle accepts a 32 mm wheel bore.

5. Clean the clamping surfaces.

6. Install the wheel without forcing it onto the spindle.

7. Ensure the wheel seats evenly between the clamping flanges.

8. Tighten the retaining hardware according to the machine manufacturer's instructions.

9. Rotate the wheel manually before powering the machine.

10. Confirm the wheel does not contact the guard or machine housing.

11. Run the machine briefly without load before beginning sharpening.

Never modify, drill, enlarge or force a grinding-wheel bore to fit an incompatible spindle.
