Ceramic grinding wheel T1 200x20x32 99A 46K white - abrasive wheel

Ceramic grinding wheel T1 200x20x32 99A 46K white is an abrasive wheel designed for precision grinding and efficient material removal on steel and other metals. The wheel uses a ceramic grain type 99A and a relatively hard bond (46K), combined with a 32 mm bore and dimensions of 200×20×32 mm. It is intended for use on bench and pedestal grinders and in toolroom or industrial environments where consistent cutting performance and long life are required.

Advantages

The ceramic grain provides high cutting efficiency and thermal resistance, reducing glazing and loading during sustained grinding. The 46K hardness offers a balance between durability and controlled wear, resulting in stable wheel geometry and predictable stock removal. The white abrasive formulation supports fine to medium surface finishes while maintaining long service intervals in demanding metalworking tasks.

Suitable for

• Precision surface grinding on hardened and alloy steels
• Toolroom dressing and profile sharpening
• Bench and pedestal grinder operations in workshops
• Light to medium industrial material removal where consistent cut is needed

When it may not be suitable

This ceramic abrasive wheel may not be appropriate for very soft non-ferrous metals (such as aluminum or copper) because ceramic grains can cause rapid loading or leave an uneven finish on soft materials. It is also not intended for use on machines or setups that cannot securely support a 200×20×32 mm wheel or where operating speeds exceed the wheel's rated RPM — consult machine specifications before mounting.

Key specifications

• Wheel type: ceramic abrasive
• Dimensions: 200 mm outer diameter × 20 mm width × 32 mm bore
• Abrasive grain: 99A (ceramic)
• Bond hardness: 46K
• Colour: white
• Intended mounting: bench and pedestal grinders, toolroom equipment

How to use

Mount the wheel on a compatible grinder with a 32 mm bore and ensure the machine is switched off and unplugged during installation. Verify the wheel's maximum operating speed against the grinder's rated RPM before use. Perform a trial run at operating speed with the safety guard in place and stand clear, listening for abnormal vibration or noise. Use appropriate coolant, dressing tools, and controlled contact pressure to manage heat and prevent glazing. Follow standard safety practices including eye, face, and hand protection while grinding.

What to consider before purchase

• Compatibility with your grinder spindle bore and maximum RPM
• Suitability for the materials you intend to grind (hardened steels vs soft non-ferrous metals)
• Required surface finish and stock removal rate for your application
• Availability of dressing tools and coolant options in your workflow

Usage recommendations

For sustained performance, dress the wheel periodically to restore cutting geometry and remove loading. Use light, consistent passes and appropriate coolant for long grinding sessions. Inspect the wheel for cracks or damage before each mounting and replace if any defects are found.
