Ceramic (NG) Flaring Cup Grinding Wheels T11 – Product Description:

Ceramic (NG) Flaring Cup Grinding Wheels T11 are constructed using the latest natural and synthetic grit configurations to the highest quality. This ensures optimum grinding efficiency and wheel longevity, whether you are simply rough grinding, removing stock or looking for that grinding solution for difficult-to-grind or heat-sensitive materials. GYSL’s next-generation grain technology offers the best grinding performance available in today’s market and our “Cyclone” Next Generation ceramic wheels are raising the standard and exceeding all expectations.


Selecting the right grain & grade:

To achieve the best possible grinding performance, it is important to select the correct wheel grade or specification. The selection should be based on 3 main considerations:

  • Grain type – depending on what material you are grinding.
  • Grit size -, depending on stock to be removed and/or surface finish requirements.
  • Hardness – depending on component material and application requirements.

Other factors such as wheel structure can affect the wheel’s grinding performance and capabilities.

Grain Types & Their Advantages:


Brown Aluminium Oxide (A) is a hard and tough grain suitable for a wide range of applications. It is commonly used for rough grinding on bench or pedestal machines providing good cutting properties and tool life.


Blue Fired Aluminium Oxide (BA) is brown fused alumina oxide that is specially treated at extreme temperatures resulting in significantly improved strength and toughness. This grain type is highly suitable for larger-diameter bench and pedestal wheels.


White Aluminium Oxide (WA) is more friable than Brown Alumina Oxide (A) which contributes to the cooling effect during grinding resulting in a better grinding performance. Suitable for grinding of most steel types and other high strength or high hardness materials where heat generation is a concern. Highly suitable for tool room, surface, and cylindrical applications where precision and control are required. Commonly used throughout most precision-based engineering applications.


Green Silicon Carbide (GC) is a very sharp and brittle grain which is extremely hard only second to boron carbide and diamond. It provides a bright clean cut and is especially suited to the grinding and sharpening of carbides and hand-held tooling. It is also suitable for the grinding of grey and cast iron, non-ferrous metals such as brass, bronze and aluminium as well as stone and rubber. It is also recommended for certain types of stainless steel and is commonly used to dress diamond-bonded wheels.


Pink Aluminium Oxide (PA) is more ductile than White Alumina Oxide (WA). The edge of the grain is very sharp and durable. It is suitable for cutting tools, gauges, precise parts, threaded workpieces, and applications where a high surface finish is required. Whilst largely replaced by low to medium percentage Ceramic wheels the pink wheel is still a favourite for operatives grinding heat-sensitive materials or fine finish surface grinding.


Light Blue Aluminium Oxide (WAB) is constructed using highly friable special alumina and a special cool cutting blue bonding agent. It is specifically designed for grinding High-Speed Steels, Tool Steels and Carbon Tool Steels such as D2 and A2. The cool bonding agent allows the wheel to remain free-cutting and cool resulting in minimal blueing or burning of the steel. Highly suited for tool room and surface grinding applications on materials around 55 Rockwell.


Ceramic Aluminium Oxide (NG) is the jewel in the crown when it comes to wheel performance. Our Ceramic grain offers next-generation technology manufactured in a sintered gel process. This results in a grain that can fracture at a controlled rate at the sub-micron level constantly creating thousands of new cutting points. This grain is exceptionally hard and strong making it the number one choice for precision grinding of hardened steels and alloys upwards of 60 Rockwell. During extensive testing on tool steels such as D2, this grade provided unrivalled performance removing stock more quickly than anything else on the market. It is also able to remain very cool providing a blemish-free surface finish.


Grit Size:

The two main considerations when deciding grit size are your dependence on either stock removal or surface finish requirements.

A coarser grit will remove stock more quickly but provide a rougher surface finish whereas a finer grit will provide a better finish but will take longer to remove stock. Another consideration is the type of grinding you are doing, for example, if you are plunge grinding and need to hold form you will benefit from a closer structure wheel and slightly finer grit.


Coarse: 24; 30; 36
Medium: 46; 54; 60; 70
Fine: 80; 100; 120; 150
Very Fine: 180; 220; 240; 280; 320; 400



The hardness of a wheel can affect its performance in several ways, softer wheels are more free-cutting and less likely to burn the component but are prone to wear more quickly. Harder wheels are more durable but may be susceptible to clogging and require more frequent dressing. Wheel hardness is determined alphabetically by a letter being placed after the grit size. The later in the alphabet the letter is then the harder the wheel.


Soft: E; F; G; H
Medium: J; K; L
Hard: M; N; O; P; Q; R; S; T; Y


Wheel Structure:

The structure of the wheel refers to the spacing or pores between the abrasive grains. An open structure contains large pores so that the grits are spaced further apart, a close structure is the opposite with grits tightly packed together. Open structures are better for grinding softer or sensitive materials, close structures offer better edge retention in precision or formed wheels.
