1. Built for Hard & Dense Concrete

The Alskar Supreme Black T-Segment Hard Concrete Diamond Blade is designed for professional applications where dense, cured and hard concrete can challenge conventional general-purpose blades.

Unlike the Green T-Segment blade, which is formulated for highly abrasive materials, the Black series is specifically positioned for:

Hard Concrete
Cured Concrete
Dense Concrete
Hard Aggregate Concrete

Its application-specific Supreme bond is designed to maintain effective diamond exposure and cutting performance when working in harder, less abrasive concrete.

The blade combines:

T-Segment Core Protection
Diamond-Bearing Ribbed Core Protection

to provide a professional cutting platform for demanding concrete applications.

2. T-Segment Protection

Integrated T-Segment Core Protection

The T-shaped diamond segment extends toward the steel core to add protection below the primary cutting edge, helping reduce premature wear and reinforce the segment-to-core area during demanding concrete cutting.

• Protected Segment Base
• Reduced Core Wear
• Professional Durability

stable performance in hard concrete

3. Diamond Ribbed Core Protection

Diamond-Bearing Protective Ribs

Diamond-bearing ribs are positioned on the steel core to provide additional wear protection and reinforce vulnerable areas of the blade body during repeated professional concrete cutting.

• Additional core protection
• Reduced side wear
• Improved blade-body durability
• Greater protection during repeated cutting

Dual Protection: T-Segments at the rim + Diamond Ribs on the core.

4. Why Ribbed Core Matters

Professional concrete cutting places repeated stress and wear on the blade body as well as the diamond segments. The Alskar diamond-ribbed core adds diamond-bearing protection to vulnerable areas of the steel core, helping maintain blade integrity and dependable performance during demanding cutting applications.

5. Supreme Quality Grade

Supreme-grade diamond and bond formulation is engineered for professional users who prioritize cutting performance, durability and dependable blade life in hard and dense concrete applications.

Best For：

• Professional concrete contractors
• Frequent concrete cutting
• Cured concrete applications
• Hard aggregate concrete
• High-production construction work
• Rental / professional equipment users

6. 8mm Sintered T-Segments

8mm sintered T-segments provide a durable cutting layer optimized for hard-concrete applications while incorporating protective geometry at the segment-to-core interface.

Supreme bond + T-Segment + ribbed core + application-specific formulation

7. Sintered Construction

The sintered diamond segment construction combines professional-grade diamond abrasive with an application-specific metal bond developed for hard, cured and dense concrete materials.

8. Hand-Finished Steel Core

Hand-Hammer Straightened Core

Each steel core is manually checked and hammer-straightened during production to help maintain blade flatness and stable running performance.
