M-Type Carbide Plum Tooth

M-Type Carbide Plum Tooth – High-Impact, Abrasion-Resistant Ground Engaging Tool for Soil Nailing, Foundation Drilling, and Geotechnical Anchoring in Challenging GCC Terrains

In geotechnical construction across the Middle East—where sandy dunes, compacted gravel, and fractured limestone define the subsurface—the performance of every soil nail, micropile, or ground anchor begins with its cutting interface. The M-Type Carbide Plum Tooth is not a generic insert; it is a purpose-engineered ground engaging tool (GET) designed to deliver aggressive penetration, exceptional wear resistance, and impact toughness in the most demanding drilling conditions—from high-rise foundation projects in Dubai to slope stabilization in Oman’s mountainous regions and oilfield access roads in Saudi Arabia’s Empty Quarter. At Qalalam Industrial Supply, our M-Type Carbide Plum Teeth are precision-brazed onto high-strength steel bodies using advanced metallurgical processes, ensuring they maintain sharp cutting geometry through thousands of meters of abrasive, rocky, or mixed-ground drilling—dramatically reducing downtime, fuel consumption, and tooling costs for contractors across the GCC.

Unlike standard button bits or flat teeth that blunt quickly in quartz-rich formations or shatter under impact in fractured rock, our M-Type Plum Tooth features a distinctive “M”-shaped carbide tip with optimized curvature, reinforced edges, and controlled cobalt content—designed to fracture rock efficiently while resisting spalling, chipping, or premature wear. Whether mounted on soil nailing rigs, drill jumbos, anchor drills, or continuous flight augers from Soilmec, Casagrande, or Bauer, our teeth provide the durability and cutting efficiency that keep your projects on schedule and on budget.

Why “M-Type”? The Geometry of Efficient Rock Fracture

The “M” profile is not aesthetic—it’s hydraulic and mechanical optimization:

• Central Peak: Concentrates force to initiate rock fracture
• Dual Flanks: Channel cuttings away from the cutting zone
• Reinforced Shoulders: Resist edge chipping during side impacts
• Controlled Rake Angle: Balances penetration force and wear life

This design excels in mixed-ground conditions—common in the UAE and Saudi—where layers shift from soft sand to hard caliche within meters.

Material Science: Toughness Meets Hardness

Our plum teeth use dual-zone carbide engineering:

• Tip Core: Fine-grain WC (0.6–0.8µm) with 6% cobalt → high hardness (91 HRA) for abrasion resistance
• Base Transition: Coarser WC (1.0–1.4µm) with 10% cobalt → high toughness (TRS > 2,800 MPa) to absorb impact

This gradient structure prevents crack propagation from the tip into the braze zone—a common failure in uniform-grade teeth.

Standard Grade: MPT-8 (8% average cobalt, bimodal grain)
Heavy-Duty Option: MPT-10C (10% Co + Cr₃C₂ for corrosive groundwater)

All carbide tips are HIP-treated to eliminate internal porosity—critical for impact resistance.

Brazing & Integration: Built to Stay Attached

A plum tooth is only as good as its bond to the steel body. We use:

• Silver-Copper Eutectic Alloy (BAg-24) with 0.15mm controlled joint gap
• Atmosphere-Controlled Brazing (not open flame) to prevent oxidation
• Post-Braze Stress Relief at 550°C to reduce residual stress
• Shear Strength Testing: > 300 MPa (verified per ISO 14193)

Result: Zero tooth loss in field trials—even in high-vibration rotary-percussive drilling.

🔧 Key feature: Braze fillet is smooth and continuous—no stress concentrators.

Frequently Asked Questions (FAQs)

Q1: What’s the difference between an M-Type Plum Tooth and a standard button bit?
A: Button bits are spherical and best for uniform, hard rock—they roll and crush. M-Type Plum Teeth have a sharp, aggressive profile designed for mixed ground (sand + rock, gravel + limestone). The “M” shape fractures rock more efficiently and channels cuttings away—critical in the variable formations common across the UAE and Saudi.

Q2: Can your M-Type teeth be used on rotary-percussive rigs?
A: Yes—our MPT-10C grade is specifically designed for high-impact drilling. The bimodal microstructure absorbs hammer energy without cracking. In tests on Saudi foundation projects, they lasted 2x longer than standard plum teeth under 1,200 BPM percussion.

Q3: How do I know when to replace the plum tooth?
A: Replace when:

• Carbide wear flat > 3mm
• Visible cracks or chips on edges
• Drilling speed drops by >25%
• Increased vibration or noise
  Pro tip: Measure meters drilled per tooth—establish a baseline for your ground type.

Q4: Do you offer custom M-profile geometries for unusual ground?
A: Yes. We’ve developed:

• Wider M-profile for soft, sticky clay
• Narrower peak for ultra-hard dolomite
• Asymmetric flanks for directional drilling
  Send a geotechnical report or core sample—we’ll optimize the design.

Q5: What’s the braze warranty? Do teeth ever pop off?
A: We guarantee zero braze failure under normal operating conditions. Our atmosphere-controlled process and post-heat treatment eliminate voids and stress. In 2+ years of GCC supply, <0.1% field failure rate.

Q6: Can you supply teeth with tungsten carbide buttons on the flanks?
A: Yes—our MPT-8+ variant includes secondary carbide buttons on the shoulders for extreme abrasion (e.g., mining overburden). Adds 15% life in quartz-rich zones.

Q7: What’s your lead time for bulk orders (e.g., 500+ teeth)?
A: 5–7 days from Dubai warehouse. We maintain buffer stock for common sizes (e.g., 22mm, 25mm shank). For custom profiles, 10–12 days.
