OTEC TX15 Super Premium Diamond Blade - 15mm Segment - Concrete & Universal - Lowest Cost-Per-Cut
Overview
The OTEC TX15 is a super premium diamond blade engineered for fast, controlled cutting of concrete and hard non-abrasive construction materials where productivity and cost-per-cut matter. Featuring a 15mm segmented rim, this blade is designed to deliver extended wear life, reduced blade changes, and consistent cutting performance on demanding construction sites.
Key Features & Benefits
- 15mm super premium segmented rim delivers extended service life and reduced tool change frequency.
- Fast cutting performance on concrete, limestone, flint aggregate, and reinforced concrete.
- integrated cooling holes improves safety and cutting stability.
- Semi-transparent steel core improves cut-line visibility during operation.
- Optimised for lowest cost-per-cut on high-volume concrete cutting tasks.
- Conforms to EN13236 for diamond blade safety and specification-led procurement.
Installation & Applications
Fit the blade to a compatible cut-off saw, ensuring the 20mm bore matches the machine spindle and the rotation direction aligns with the arrow on the blade. Apply steady cutting pressure and allow regular cooling breaks during extended cutting cycles.
- Concrete, reinforced concrete, and in-situ concrete
- Limestone and flint aggregate concrete products
- Kerbs, slabs, concrete paviors, and yorkstone
- Medium to hard bricks and general construction materials
This blade is not suitable for metal, very hard materials, or asphalt. For a full list of compatible applications, refer to the OTEC product catalogue.
Who Is This For?
- Concrete and groundworks contractors requiring fast cutting and long blade life
- Site teams cutting reinforced and hard concrete products daily
- Hire fleets specifying super-premium blades for durability and reduced downtime
- Procurement teams focused on lowest cost-per-cut and long-term value
Competitive Advantages
The TX15 is optimised specifically for concrete and hard non-abrasive products. The 15mm segment height delivers extended wear life, while the semi-transparent cooling design improves visibility and cutting control, helping reduce operator fatigue and blade replacement costs.
