Milling Cutter Carbide Tips

Carbide Road Milling Cutter Tips — Manufacturer & Supplier

Ruixin carbide tips for road milling machine cutters are cemented tungsten carbide inserts designed for cold milling of asphalt and concrete road surfaces. Engineered for wear resistance and thermal stability under the high-speed abrasive cutting conditions of road planing machines. Manufactured at our 14,200m² ISO-certified facility in Jinan, Shandong.

Quick Grade Selection

Surface Type	Grade	Key Advantage
Standard asphalt milling	SR7X / SR8C	High wear resistance HRA 89–91 for abrasive surfaces
Concrete & composite road surfaces	SR8C / SR10C	Higher toughness TRS ≥2200MPa for hard aggregate
Heavy-duty urban milling / high aggregate content	SS16CB / SS18CB	Coarse grain 4–6μm — impact + wear balance

Full Grade Specifications

Grade	Density (g/cm³)	Hardness (HRA)	TRS (MPa)	Grain (μm)	Best For
SR7X	14.70±0.05	91.0±0.5	≥2000	1.0–1.2	Max wear resistance — abrasive asphalt milling
SR8C	14.65±0.05	89.0±0.5	≥2200	2.0–3.0	Balanced wear + toughness — concrete/asphalt
SR10C	14.45±0.05	88.0±0.5	≥2200	2.0–3.0	Higher toughness — hard aggregate, urban milling
SS16CB	14.70±0.05	87.5±0.5	≥2200	4.0–6.0	Heavy-duty milling with high impact loading
SS18CB	14.60±0.05	87.0±0.5	≥2400	4.0–6.0	Heavy-duty milling with high impact loading

Frequently Asked Questions

Are your carbide milling tips compatible with Wirtgen road milling machines?

Yes. We manufacture carbide tips compatible with Wirtgen, Bomag, Caterpillar, Volvo, and other major cold milling machine platforms. Send us your current tip part number or dimensions (shank diameter, tip height, brazing interface) and we will confirm compatibility or produce to drawing.

Which grade should I use for milling concrete road surfaces?

Concrete milling is more demanding than asphalt due to hard aggregate (granite, basalt) embedded in the matrix. We recommend SR8C or SR10C for standard concrete, which offer a higher toughness-to-hardness ratio. For high-silica aggregate or reinforced concrete, SS16CB provides coarser grain and higher impact resistance. Contact us with your surface specification for a specific recommendation.

What is the MOQ and lead time for road milling carbide tips?

Sample orders of 20–50 pieces are accepted for field trials. Bulk orders typically start from 500 pieces per grade. Lead time is 5–7 days for samples and 3–4 weeks for production quantities. Long-term supply contracts for road construction projects are available.
