Hard Materials Diamond Blade – Super Premium – 10mm Segment – OTEC LT10R is a super premium diamond blade developed for professional use on UK construction, infrastructure, and civil engineering sites where very hard materials place increased demands on cutting performance.
It is intended for contractors and site operatives working with hard concrete, granite, hard natural stone, clay products, and engineering bricks. The blade is also capable of cutting metal, making it suitable for mixed-material site environments where versatility is required.
The LT10R is not recommended for asphalt or highly abrasive materials. It should not be specified for asphalt, green concrete, render, cement screed, or lignacite blocks, and should be used within its intended hard-materials application range.
On UK construction and infrastructure sites where very hard materials and occasional metal elements are encountered together, maintaining stable cutting performance without frequent blade changes is critical. Hard Materials Super Premium Diamond Blade – OTEC LT10R is intended for use in these demanding mixed-material site conditions.
✓ Engineered for fast, stable cutting of very hard materials
✓ Supports reliable performance on hard concrete, granite, and natural stone
✓ Reinforced flange design contributes to blade stability during demanding cuts
✓ Turbo segment profile supports smooth cutting action across varied materials
✓ Capable of cutting metal without compromising operator safety
✓ Suitable for universal site use where material types may vary
✓ Developed for consistent performance on UK construction and infrastructure sites

Before use:
Ensure the blade specification is suitable for the material being cut. Inspect the blade for cracking, segment damage, undercutting of the steel core, uneven wear, or other defects. Confirm that the rotation direction matches the arrow on the blade and that the bore size matches the machine spindle. Wear appropriate PPE and ensure machine guards are correctly fitted.
During use:
Do not apply excessive force when cutting. Allow the blade to cut at its designed speed and take regular cooling breaks. If overheating occurs, reassess material suitability. A blunt blade may be refreshed by cutting a soft abrasive material such as brick or block. Ensure the material being cut is firmly secured and frequently check the blade for signs of damage.
Wet cutting:
If wet cutting is used, ensure a continuous and adequate water supply is applied to both sides of the blade.
Is the OTEC LT10R suitable for cutting very hard materials?
Yes. The LT10R is designed for very hard and dense materials such as granite, engineering bricks, hard clay products, and very hard concrete.
Can this blade be used on reinforced concrete?
Yes. Reinforced and hard unabrasive concrete fall within the intended application range of the LT10R.
Is the LT10R suitable for metal cutting?
It can be used for occasional metal cutting, including exposed steel and rebar, where site conditions require versatility. It is not intended as a dedicated metal cutting blade.
Can this blade be used for asphalt cutting?
No. The LT10R is not suitable for asphalt, green concrete, render, cement screed, or other highly abrasive materials.
What machines can the LT10R be used on?
Depending on blade diameter and bore, the LT10R is suitable for use on angle grinders, large angle grinders, petrol cut-off saws, and floor saws, provided maximum RPM limits are respected.
Is this blade compliant with UK safety standards?
Yes. The LT10R is manufactured in accordance with EN13236, the recognised safety standard for diamond blades used on UK construction sites.
