Product Introduction
The road mixer bullet head is a core consumable cutting component engineered for road rehabilitation and soil-stabilization machinery. Built to withstand high-impact grinding against gravel, lime-earth mixtures and compacted subgrade, this mixer bullet teeth delivers stable cutting performance under continuous heavy-load operation. We supply bullet teeth for tractor mounted road mixer in two mainstream specs: model 20 mixer bullet teeth and model 22 variants. Our road stabilizer bullet-tooth bit integrates high-strength alloy steel body and premium carbide tip, avoiding premature tip loss and rapid matrix abrasion that plague low-cost alternatives. As a key replaceable wear spare, this road mixer bullet head allows quick field swap to cut machine downtime for bulk buyers and project contractors.

Process & Technology
Forging forming
The steel substrate adopts hot die-forging process to optimize internal metal grain structure, improving anti-shock capacity to resist bending or fracture under rock-mixed working conditions.
Brazing technology
High-temperature vacuum brazing locks tungsten carbide tip firmly onto tooth body; it reduces tip-drop failure caused by vibration and thermal cycling during long-hour mixing.
Surface heat-treatment
The tooth body undergoes precise quenching-tempering treatment, balancing surface wear resistance and core toughness to prevent tooth shank cracking.
Precision machining
Shank and locating flange are CNC-machined, guaranteeing precise fitting with tool holder for smooth rotation while working.
Application Fields
- Lime-soil subgrade mixing, road base stabilization with lime soil mixer cutter teeth
- Old pavement cold-recycling reconstruction using heavy-duty bullet teeth for cold recycling machine
- Subgrade renovation, soil homogenization with subgrade mixer bullet teeth
- Tractor-mounted road mixer and disc trencher trench-cutting jobs, applying bullet teeth for tractor mounted road mixer
- Highway, county-road maintenance and earth-road rebuilding projects, with two options model 20 bullet teeth and model 22 bullet teeth for different power-grade machines.
Common Customer Failures & Solutions
Carbide tip falls off prematurely
Cause: Overheating from insufficient cooling, poor brazing quality or hitting large hard boulders. Solution: Check machine water-spray cooling system; avoid direct impact on huge rock blocks; purchase our factory-produced tungsten carbide bullet teeth with vacuum brazing craft.
Tooth shank severe wear, cannot rotate freely in holder
Cause: Abrasive dust invades clearance space, long-term continuous operation without inspection. Solution: Periodically take out teeth, clean tool holder cavity; replace damaged protective washer; stock spare mixer bullet teeth for timely replacement.
Uneven rapid wear across the whole set of teeth
Cause: Incorrect installation angle, partial tool holder deformation. Solution: Inspect tool holder deformation before mounting road mixer bullet head or model22 series; strictly follow installation angle requirement.
