Global Leading Diamond Tool Manufacturer.
Installing underfloor heating in an existing concrete floor often requires cutting wide, consistent grooves for heating pipes. When the floor is made of extra hard concrete, this job becomes much more demanding than standard concrete cutting.
To meet this application, Johnson Tools has developed a new 130mm 8-segment diamond tuck point blade for underfloor heating grooving. Unlike a standard cutting blade, this product is designed specifically for wide groove cutting in extra hard concrete floors, with a special 8-segment structure, 16mm or 17mm segment thickness, and laser-welded construction.
For contractors, underfloor heating installers, and diamond tool distributors looking for a professional concrete grooving blade, this new design provides a dedicated solution for floor heating groove cutting.
A standard diamond blade is mainly designed to make a narrow kerf through concrete, masonry, or other construction materials.
An underfloor heating grooving blade, however, has a different job. Instead of simply cutting through a material, it needs to remove enough concrete to create a groove wide enough for heating pipes or cables.
This means the blade must handle:
The Johnson Tools 130mm diamond tuck point blade is designed around these requirements.
Its most noticeable feature is the special 8-segment structure, which combines wide diamond segments with large spaces between the cutting sections.
The blade uses eight specially shaped diamond segments positioned around the steel core.
This configuration is different from many conventional segmented blades because the product is intended for wide concrete groove cutting, not ordinary narrow cutting.
The 8-segment layout helps provide stable support during grooving while leaving sufficient open space between the segments for concrete dust and debris evacuation.
For this reason, the blade is particularly suitable for demanding applications such as:
underfloor heating groove cutting in extra hard concrete floors.
The design also makes this product a highly specialized 8 segment diamond tuck point blade for professional floor heating installation.
One of the biggest differences between this product and a standard concrete cutting blade is the cutting width.
The Johnson Tools floor heating blade is available with:
16mm or 17mm segment thickness.
This makes it suitable for applications where a relatively wide channel must be created in a single grooving process.
Instead of making multiple narrow cuts with a conventional blade, a dedicated 16mm concrete grooving blade or 17mm concrete grooving blade can create a wider groove more efficiently.
This is especially useful for underfloor heating installation, where the groove needs to accommodate heating pipes while maintaining a consistent width along the floor.
The 10mm segment height also provides sufficient working diamond depth for professional concrete floor grooving.
This product is not intended as a universal concrete blade.
It is designed specifically for:
Extra Hard Concrete
Extra hard concrete creates greater cutting resistance than softer or more abrasive concrete. During wide groove cutting, the blade is exposed to significant friction and heat because a much larger section of diamond segment remains in contact with the floor.
For this reason, the bond and diamond formulation need to match the hardness of the material.
Johnson Tools develops different diamond formulas according to the material and working conditions. For this particular diamond grooving blade for extra hard concrete, the segment formulation is selected specifically for hard, dense concrete floor applications.
This focused application helps the blade maintain more stable cutting performance under demanding grooving conditions.
Cutting a thin line in hard concrete is already demanding, but cutting a 16mm or 17mm wide groove creates an even greater load on the blade.
Several factors make the job difficult.
Extra hard concrete has a dense structure and offers strong resistance to the diamond segment.
When the cutting width increases, the total contact area between the blade and concrete also increases.
Wide groove cutting generates more friction than conventional narrow cutting.
If heat is not managed properly, the segment can lose cutting efficiency and the blade may require more cutting force.
Underfloor heating installations often involve long groove paths throughout an entire room or building.
The blade therefore needs to perform consistently during repeated and continuous groove cutting.
Grooving removes a relatively large amount of concrete material.
The open spaces between the eight segments help provide room for dust and debris to move away from the cutting zone.
This is one of the important reasons why the special 8-segment structure is suitable for this type of application.
The Johnson Tools underfloor heating diamond blade uses laser-welded diamond segments.
Laser welding creates a strong connection between the diamond segment and the steel core.
This is particularly important for a wide groove diamond blade, because thick segments experience greater mechanical stress during cutting than standard thin cutting segments.
The main advantages of laser-welded construction include:
For contractors working on extra-hard concrete floors, strong segment attachment is an important factor in blade reliability.

This specification makes the product suitable for professional 130mm underfloor heating grooving applications where a wide and stable groove is required.
Underfloor heating systems are commonly installed using pipes or cables positioned beneath the finished floor.
In renovation projects, one method is to cut grooves directly into the existing concrete or screed surface.
A typical process includes:
Because this blade has a 16mm or 17mm cutting width, it is designed specifically for producing wide channels rather than ordinary narrow saw cuts.
It is important to distinguish between a standard concrete blade and a dedicated floor heating grooving blade.
A normal diamond blade is primarily designed to cut through concrete.
Its kerf is usually relatively narrow.
A standard tuck point blade is commonly used for applications such as mortar removal, crack repair, and masonry joint cleaning.
An underfloor heating grooving blade is different.
Its purpose is to remove a wider section of concrete and create a controlled channel.
The Johnson Tools blade combines:
This makes it a dedicated diamond blade for underfloor heating groove cutting, rather than a general-purpose concrete blade.
Using the correct blade for the application can improve both cutting efficiency and groove consistency.
A dedicated concrete floor grooving blade offers several practical advantages.
The 16mm or 17mm segment thickness determines the width of the groove.
This helps create a more consistent channel for heating pipe installation.
A wide grooving blade can create the required channel directly, reducing the need to make multiple narrow cuts.
The 8-segment configuration is designed to provide stable support while cutting a wide groove.
The segment bond is developed specifically for extra hard concrete rather than being a universal formula for many different materials.
This product is particularly suitable for:
It is especially relevant for companies working on renovation projects where heating pipes need to be installed into existing extra hard concrete floors.
For distributors, the product also offers a differentiated 8-segment underfloor heating diamond blade compared with conventional tuck point blades.
