Carbide grinding blades are versatile tools that many use for remedial projects. Ideal for grinding or removing materials such as grout and mortar, this tool offers more than one use and makes a great addition to any tool kit.

At Sealants & Tools Direct, we are experts in all things tools, and we have put together a complete guide to help you decide which carbide grinding tool will aid in your next project, how to use it effectively, the different types and where you can get yours.

What are carbide grinding blades?

Carbide grinding blades are cutting tools used in various construction industries on products that entail machining and grinding applications to remove material from a workpiece. They are hardwearing and designed to withstand cutting and grinding through tough materials without wearing out quickly like other materials. This is due to the carbide, a hard and durable material with wear and heat resistance properties.

What are carbide grinding blades used for?

Carbide grinding blades have many uses in a range of industries. Some commonly used applications include:

  • Tool cutting and grinding
  • Surface grinding
  • Cylindrical grinding
  • Centerless grinding
  • Precision grinding.

As well as removing materials from a surface to achieve a high-quality finish, carbide grinding blades can sharpen and shape various tools. They are available in multiple sizes and shapes depending on the task. Carbide grinding blades can be brazed onto a grinding tool or mounted to a grinding wheel.

Who uses carbide grinding blades?

Wood flooring installers and any construction worker can use a carbide grinding blade, as this tool is versatile and handy for many project types.

A wood flooring installer could use a carbide grinding blade for:

  • Subfloor preparation to ensure the floor is flat and level before installing hardwood
  • Remove adhesive residue such as glue
  • Repair high edges, scratches or uneven transitions between the boards
  • To shape and contour stair treads and riders on staircases
  • Edge grinding and detail work, particularly for areas where large sanding grinders can't get to
  • Create expansion gaps between the boards.

A construction worker could use a carbide blade for:

  • Concrete surface preparation, grinding and polishing
  • Tile, grout and mortar removal
  • Asphalt cutting and repairs
  • Metal and hard plastic cutting, trimming and shaping
  • Removing rust and coatings

Other professions that use a carbide grinding blade are metal workers, woodworkers, masons and stone workers, construction workers, tile installers, automotive mechanics, fabricators, glassworkers and general DIY enthusiasts.

Choosing a carbide grinding blade


Choosing the right carbide grinding blade requires careful consideration to optimise performance, use safety, and the finished work's overall quality. The choice of carbide blade comes down to the grade, size and shape, and which one will depend on the type of work being carried out and the desired finish.

Carbide grinding blades can be used on most materials, including metals, concrete, stone, wood, plastic and many more, so the type of material won't determine your choice, but what you intend to do with that material will. Are you shaping? Cutting? Grinding? Removing material?

The choice of shape, from discs, wheels and blades, needs to align with the surface profile that you're working with, as well as the size and diameter of the blade. Once you have chosen the right carbide grinding blade or disc for the job, have a test run on a spare piece of material to ensure the blade fits the purpose.

Carbide grinding blades

Here are some examples of carbide grinding blades and how they differ.

Our carbide tile and grout remover saw blade is an 88mm carbide ceramic cutting and group removal saw blade. It's a universal multi-function tool fitment with a tool-free, quick-change design. This tool is compatible with standard multi-tool machines. This tool is specifically designed to remove ceramic or porcelain tiles and grout from surfaces such as walls and floors, making it ideal for renovation and remodelling projects.

The carbide tile, grout and mortar removal blade is a 65mm radial saw, multi-tool function blade. Universal multi-function tool fitment open-backed tool, free quick change design. This tool can remove tile grout, mortar, cement and shape ceramics and masonry-based products. It works well on fibreglass and other composite materials and is often used by decorators to remove rust and paint from hard objects like railings.

Our carbide grout, adhesive, and paint removal blade is a 78mm triangular carbide grout and mortar removal, stone and masonry grinding saw blade. It can also be used to grind back old adhesive when tiling or in other applications where the removal of bulk materials, such as paint from metal railings, is needed. The tool's distinctive design makes it effortless to reach challenging corners.

Carbide grinding blade vs carbide grinding disc


Carbide grinding blades and carbide grinding discs are tools made of the same material but hold different shapes, suitable for different applications. A disc typically has a flat, rounded shape, and they're often used with angle grinders and surface grinding machines for flat or curved surfaces. Blades are flat and thin and are better used on applications that require cutting or shaping.

An example of a disc is our 115mm carbide grinding disc, designed for fast removal on various surfaces. It is ideal for removing rough concrete, fibreglass, stone, tiles, brick, and rust.

Carbide mortar rake

Another option is to use a carbide mortar rake, a tool primarily designed to remove old mortar between bricks, blocks or stones. Carbide mortar rakes can be used as handheld tools or with angle grinders.

Always check the compatibility of your carbide grinding tool, as they can be used with various tools, depending on their design. This includes angle grinders, circular saws, jigsaws, reciprocating saws, tile saws, bench grinders, handheld grinders and many other power tools. Make sure you choose a carbide grinding product that is compatible with the tool you intend to use on your project.

How to use a carbide grinding blade efficiently

The specific usage of this tool will depend on the work being carried out, but there are several general guidelines to follow to ensure safety and efficiency of use.

  • Wear protective gear to protect yourself from harm
  • Inspect the blade for damage before use
  • Make sure the work surface you're working with is secure and isn't going to move
  • Mount the blade securely to the tool and make sure it isn't going to come loose
  • Select the right job for the blade and always test it first before using it on the final project surface
  • Set the speed- slow and best to begin with
  • Position the blade correctly at the right angle and apply sufficient pressure
  • Take your time and grind in stages, stop and inspect your work as you go
  • For long usage, give the blade time to cool and properly lubricate if needed.

Often, other tools will be needed to complete the task. For additional tools, look at our product categories, where you will find abrasives, glass paper, and sanding and smoothing a surface.

Abrasives are often used alongside carbide grinding blades to enhance the cutting, grinding, cutting or shaping process, depending on the application. Abrasives and glass paper can often help prepare the surface for grinding, deburr the edges to be safe and smooth, or remove material from the surface.
