APPLICATION FIT
Where this solution applies
Operating tasks

Buying & engineering roles
- Foundation contractors
- Trenching contractors
- Tool manufacturers
- Fleet and site engineers
WORKING CONDITIONS
Inputs that control grade and geometry
A useful recommendation starts with the load, environment and mating system. Include measured data when available and describe field conditions when it is not.
- Soil profile, boulders and rock bands
- Rock strength, abrasivity and moisture
- Torque, crowd force and rotation speed
- Cutter spacing, angle and cleaning
COMMON FAILURE MODES
Diagnose the mechanism before changing material
- Tip fracture at obstructions
- Accelerated abrasive wear
- Insert loss or braze damage
- Body erosion and uneven cutter loading
COMPLETE TOOL + CARBIDE
Engineer the interfaces, not only the insert
Assemblies and components
- Piling and auger cutter teeth
- Chain trencher carbide picks
- Rotary drilling cutter bits
- Brazed or press-fit complete assemblies
Custom decisions
- Grade by impact and abrasivity
- Tip geometry and attack-angle review
- Connection and steel-body interface
- Sample matching for replacement tools
Capability note: complete assemblies are evaluated against the drawing, sample, production volume and available technical evidence. No field-life claim is made until a controlled trial is completed.
VERIFIED COMMERCIAL EVIDENCE
Published evidence for foundation and trenching projects
Ruixin publishes real studio photographs and catalogue data for rotary-drilling inserts and tunneling-tooth carbide. These products are relevant inputs for foundation and trenching tools, but the photographs are not auger, bucket, trencher-chain or customer-site assemblies.
Rotary-drilling carbide cutter inserts
Ruixin studio product photograph of current rotary-drilling insert geometries. Final tooth body, attack angle and assembly are project-specific.

Tunneling-tooth carbide geometries
Ruixin studio product photograph relevant to high-impact soil-and-rock cutting. It is not a piling bucket or trencher installation.
Open source product →Published grade envelope
The linked rotary and tunneling catalogues publish fine-to-coarse carbide grades covering approximately HRA 85.5–90, TRS at least 2200–2900 MPa and grain size 2–8.5 μm for impact-versus-abrasion trials.
View grade range →Geometry development scope
Custom tip, shank and OEM tooth geometries are published for drawing- or sample-based review. Attack angle, body support, brazing and retention must be approved at assembly level.
View geometry scope →Sample and delivery scope
Published sampling is 20–50 rotary inserts or 20–100 tunneling-tooth pieces per grade, normally 5–7 days. Typical bulk lead time is listed at 3–5 weeks after drawing and order review.
View sample terms →Inspection documentation
Published shipment records include hardness, density and grain structure. Critical tooth dimensions, joining quality and complete-assembly inspection require an agreed project control plan.
View inspection scope →Evidence status
Evidence still required: real piling tooth, auger, bucket or trencher-chain assemblies; approved steel-body and joining details; a redacted dimensional/material report; and an anonymous job case with soil log, machine, cutter position, baseline and measured result.

FAQ
Questions engineering teams ask first
What should be shared for a piling-tool recommendation?
Provide the rig and tool type, tooth position, soil and rock log, obstructions, current tool specification, damage photographs and the target drilling interval.
How do mixed soil and rock affect carbide selection?
Abrasion in soil and impact at rock bands create competing requirements. The recommendation balances grade toughness, wear resistance, tip geometry and tool-body support.
Can an existing tooth be reproduced from a sample?
A sample can support dimensional review and material analysis. Production feasibility and tolerances are confirmed before a sample batch is quoted.
