How Durable is Tungsten Carbide? KOIHO BETTER CARBIDE`s Milling Solutions

The Durability of Tungsten Carbide

Tungsten carbide, a composite of tungsten and carbon, is celebrated for its extraordinary hardness, ranking 8.5-9 on the Mohs scale, just shy of diamond. Its key durability features include:

• Scratch Resistance: Resists wear from abrasive surfaces, maintaining tool integrity.

• High Melting Point: Withstands 2,870°C, ideal for high-friction milling.

• Impact Strength: Absorbs shocks without cracking, even under stress.

At KOIHO BETTER CARBIDE, our asphalt milling picks harness these properties, using micrograin carbide tips to deliver lasting performance on machines like Dynapac’s PL2000 or Roadtec’s RX-700.

Why Durability Matters in Asphalt Milling

Asphalt milling grinds old pavement into reclaimed asphalt pavement (RAP), or millings, reducing paving costs by 30-50% compared to new asphalt. These millings are ideal for:

• Driveways

• Roads

• Parking lots

However, milling is tough on tools. Pavement often contains abrasive aggregates or metal fragments, eroding standard bits and causing delays. Poor milling produces coarse millings, leading to weak surfaces.

KOIHO’s pavement milling teeth, built with tungsten carbide’s durability, excel here. Their carbide tips, brazed to reinforced steel bodies, resist wear and deliver uniform millings for seamless compaction on planers like Bomag’s BM 2200/60.

KOIHO’s Durable Tungsten Carbide Tools

KOIHO BETTER CARBIDE’s road planing bits are engineered for resilience and precision, featuring:

• High-Grade Carbide Tips: Micrograin tungsten carbide for superior hardness.

• Robust Steel Bodies: Withstand intense milling stresses.

• Wear Plates: Protect toolholders from abrasion.

• Clamping Sleeves: Enable quick replacements, minimizing downtime.

These features cut maintenance costs and boost efficiency on machines like XCMG’s XM200K or Volvo’s PL1600. KOIHO’s asphalt grinding bits excel in tasks from surface planing to deep pavement removal, producing high-quality millings that enhance sustainability by reducing fuel use.

Practical Tips for Milling Success

Maximize asphalt millings with KOIHO’s tools and these strategies:

• Assess Pavement: Choose the right bit for asphalt or concrete—KOIHO offers tailored options.

• Maintain Drums: Clear debris and check sleeve alignment for precise cuts.

• Bind Millings: Use asphalt binder for stable, weather-resistant surfaces.

KOIHO’s pavement milling teeth ensure consistent, finely graded millings, streamlining paving and cutting costs for durable, eco-friendly results.
