Carbide Mushroom Tooth

Carbide Mushroom Tooth Inserts — Shield Picks Supplier

Ruixin carbide mushroom tooth inserts are cemented tungsten carbide tips for shield machine picks, engineering picks, and construction cutting tools. The mushroom-shaped geometry provides high impact load distribution across the tip base, resisting fracture under the percussion and lateral forces encountered in medium-hard to hard rock cutting. Manufactured at our 14,200m² ISO-certified facility in Jinan, Shandong.

Quick Grade Selection

Application	Grade	Key Advantage
Shield machine picks — medium-hard rock	SS16CB / SS18CB	Balanced wear resistance + impact toughness
Engineering picks — hard formation	SS20CB	Maximum wear resistance in CB series
Complex/variable geology	SS18CC / SS20CC	Coarse grain 7–8μm for maximum toughness
Heavy-duty / high-power picks	SS15CT / SS16CTA	Very high TRS ≥2800MPa for hard complex strata

Frequently Asked Questions

What is a carbide mushroom tooth and where is it used?

A carbide mushroom tooth is a cemented tungsten carbide insert with a domed or mushroom-shaped head. It is brazed into a steel pick body and used on shield machine cutterheads, roadheader drums, and engineering picks for cutting rock, concrete, and hard soil formations. The geometry spreads impact load across the base flange, reducing tip fracture under percussive and lateral cutting forces.

What is the MOQ and lead time for mushroom tooth inserts?

Sample orders of 20–100 pieces per grade are accepted. Bulk orders typically start from 500 pieces. Lead time is 5–7 days for samples and 3–5 weeks for production volumes. We can align delivery schedules with project start dates for large tunneling contracts.

Can you match our existing mushroom tooth dimensions?

Yes. Send us your current insert drawing (DXF, PDF, or STEP) or a physical sample and we will replicate the exact base diameter, head height, dome radius, and brazing shoulder dimensions. Custom alloy grade is also available.
