OTEC Z15P Professional Diamond Blade – 10/12mm Segment – Concrete & General Purpose – EN13236 Certified

Product Name

OTEC Z15P Professional Diamond Blade – 10/12mm Segment – Concrete & General Purpose – EN13236 Certified

Overview

OTEC Z15P is a professional concrete diamond blade for reliable, fast cutting across concrete & general masonry on active UK construction sites.

It is primarily designed for concrete, limestone, flint aggregate, reinforced concrete, and hard non-abrasive concrete products, with additional capability for kerbs, slabs, medium to hard bricks, yorkstone, and concrete paviors.

With occasional use only, it can also tackle very hard materials such as granite, hard natural stone, hard clay products, concrete roof tiles, sandstone, and abrasive concrete paviors; it is not suitable for metal or asphalt.

Who Is This For? (Typical UK Site Scenarios)

• Groundworks contractors cutting reinforced concrete bases & edge beams on live housing developments where predictable cutting reduces delays.
• Civil engineering teams using 350mm & 450mm floor saws to cut slabs & access channels where consistent depth supports programme planning.
• Highways and public-realm contractors cutting kerbs, slabs & paviors where clean edges help avoid rework.
• Hire fleets specifying professional-grade blades to reduce misuse, returns & premature wear across mixed users.
• Procurement teams standardising diameters & compliance across multiple sites to reduce substitutions and ordering errors.

How to Specify & Use on Site

How to specify: Select diameter by saw type (300mm for handheld saws; 350mm or 450mm for floor saws), confirm bore compatibility, and ensure the blade rating matches the machine running speed (the 300mm option is suitable for running at up to 6400 RPM).

How to use: Before fitting, inspect for cracks, segment detachment, undercutting, uneven wear, or other defects; align the rotation arrow with spindle direction; use guards and eye protection; avoid excessive cutting force; and allow regular cooling breaks.

• If overheating occurs, the material may be too hard; pause for cooling and reassess suitability.
• A blunt blade can be refreshed by running in a soft abrasive material such as brick or block.
• If wet cutting, ensure a plentiful water supply to both sides of the blade.

Frequently Asked Questions

Is the Z15P suitable for everyday concrete cutting on site?
Yes. It is designed for regular use on concrete and hard non-abrasive concrete products, with additional capability for common masonry such as kerbs, slabs, and paviors.

Can it be used on reinforced concrete?
Yes, reinforced concrete is within the intended application range when used correctly and when the blade rating matches the saw specification.

Which diameter should we specify for handheld vs floor saw work?
Use 300mm for handheld saws and specify 350mm or 450mm for floor saws, then confirm bore and RPM compatibility against the machine requirements.

Is this blade compliant for UK site use?
It conforms to EN13236, the recognised standard for diamond blades used across Europe and the UK, supporting procurement compliance and safer site selection.

Can it be used on asphalt or metal?
No. It is not suitable for asphalt or metal; using it outside its intended range can reduce performance and increase safety risk.

What should we do if cutting slows down or the blade feels blunt?
Do not force the cut. Allow cooling breaks and refresh the blade in a soft abrasive material such as brick or block; if issues persist, stop use and consult your supplier.
