DSWORD – HELI –4T4702TL/4T4702RC J700/ CAT374/ 375/390 /995 Forged Bucket Teeth / Forged from high-quality alloy steel; wear-resistant and rugged; available for global wholesale.

In the extreme digging environment of large‑scale mining and mass excavation, Caterpillar’s 374, 375, 390, and 995 excavators represent the top tier of hydraulic power and bucket capacity. The teeth on these buckets face a relentless assault: high‑pressure abrasion from hard rock, enormous breakout forces, and severe impact loads. The J700 series forged bucket teeth, identified by part numbers 4T4702TL (TL‑style) and 4T4702RC (RC‑style), are designed to handle exactly these conditions.

HELI‑DSWORD manufactures these teeth as a rugged, wear‑resistant forged solution, produced from high‑quality alloy steel with a focus on extreme durability and long service life. We supply these teeth on a global wholesale basis, directly from our manufacturing facility. I’m Jack, from the HELI‑DSWORD international affairs team, and I’ve personally written this article to take you through the metallurgy, forging discipline, and rigorous inspection that make our 4T4702TL and 4T4702RC teeth a reliable choice for the world’s most demanding excavators.

1. HELI‑DSWORD: A Full‑Spectrum OEM/ODM Manufacturer Serving 5t to 400t Equipment, with Teeth up to 150t

HELI‑DSWORD is a dedicated OEM and ODM manufacturer of heavy‑duty undercarriage systems and ground‑engaging tools. Our engineering and manufacturing range covers tracked machinery from 5 tonnes to 300 tonnes, and we have pushed our undercarriage platform to 400‑tonne‑class ultra‑heavy equipment. In the specific segment of ground‑engaging tools, we have forged bucket teeth, adapters, and ripper tips for excavators and dozers up to 150 tonnes — well within the range of the 95‑tonne class CAT 995 and its siblings.

Our product expertise extends across a comprehensive range of tracked machinery:

• Crawler excavators (including the largest Caterpillar mining models)
• Bulldozers
• Crawler drilling rigs
• Crawler cranes
• Tracked loaders
• Tracked pavers
• Tracked conveyor systems

This broad foundation means our 4T4702TL and 4T4702RC teeth are not simply dimensionally correct — they embody the wear‑resistant metallurgy and structural integrity lessons learned from engineering ground‑engaging tools for the most severe applications.

2. Self‑Built Factory with 100% In‑House Production for Consistent, Reliable Quality

On a CAT 995 bucket digging in blasted granite, a bucket tooth that fails due to internal defects or inconsistent heat treatment can cause catastrophic damage and hours of lost production. To guarantee that every tooth we ship performs identically, HELI‑DSWORD operates from a self‑built industrial campus where every production line is company‑owned and operated. No core manufacturing step is outsourced.

Every tooth manufactured under part numbers 4T4702TL and 4T4702RC undergoes a fully in‑house production chain:

• Incoming alloy steel chemistry verification via spectrometry
• Precision hot die forging under strictly controlled temperature parameters
• CNC machining of the adapter nose pocket, retention pin slot, and working profile
• Targeted quenching and tempering heat treatment of the working face
• 100% non‑destructive flaw detection on each individual tooth
• Random batch destructive cut‑up inspection
• Dimensional verification against Caterpillar’s J700 engineering tolerances
• Anti‑corrosion coating and final quality release

Because every operation is under our direct control, the quality of a 4T4702TL tooth delivered to a mine in Australia is identical to one shipped to a quarry in Europe — fully traceable, fully repeatable.

3. OEM Manufacturing Partnerships and a Catalog of Over 20,000 Products

Our manufacturing standards are confirmed every day by the original equipment manufacturers we serve. HELI‑DSWORD is an active OEM manufacturing partner for leading global brands, including:

• Hitachi
• LiuGong
• XCMG
• KOBELCO
• SDLG (LGCE)

We produce undercarriage components and forged wear parts that are installed on new machines on these manufacturers’ assembly lines, conforming strictly to their technical drawings, material specifications, and audit protocols. This OEM discipline is directly applied to our aftermarket production: the same engineering rigor and inspection gates stand behind every 4T4702RC and 4T4702TL tooth.

Our active product catalog has grown to more than 20,000 individual part numbers, spanning undercarriage parts and ground‑engaging tools for a vast array of Chinese domestic and international equipment brands. This extensive reference base allows us to serve customers who require a reliable global wholesale source for multiple tooth types and machine models with accuracy and efficiency.

4. Inside the 4T4702TL/4T4702RC J700 Tooth: High‑Quality Alloy Steel, Molybdenum, Heat Treat, and Dual‑Level Inspection

Here is precisely how HELI‑DSWORD builds these J700 series teeth to deliver the wear resistance, ruggedness, and impact toughness that CAT 374–995 excavators demand.

High‑Quality Alloy Steel Forging with Molybdenum — The tooth is hot‑forged from a premium alloy steel that includes molybdenum (Mo) as a critical alloying element. Molybdenum significantly improves hardenability, refines grain structure, and promotes the formation of fine, hard carbides that resist abrasive wear far better than conventional chromium‑based steels. The forging process orients the metal grain flow along the tooth profile, maximizing fatigue strength at the adapter pocket and the cutting tip. The result is a tooth that resists dulling, deformation, and breakage under the extreme digging forces exerted by a CAT 390 or 995.

Targeted Quenching and Tempering of the Working Face — After forging and machining, the working face and tip zone receive a precisely controlled quench‑and‑temper heat treatment. This creates a deep, wear‑resistant hardened layer on all ground‑engaging surfaces, while the core remains tough and ductile to absorb high‑impact shock. The tempering parameters are calibrated to achieve the exact hardness range that balances maximum abrasion resistance with crack resistance — essential for large teeth on high‑capacity mining buckets.

100% Non‑Destructive Testing (NDT) — Every single finished tooth undergoes 100% non‑destructive flaw detection. We use magnetic particle and ultrasonic inspection to scan the entire tooth body, adapter pocket, and tip for any sub‑surface cracks, forging laps, porosity, or inclusions. A hidden internal flaw could cause a catastrophic tooth fracture at the digging face, potentially damaging crushers and stopping production. Our 100% NDT protocol completely eliminates that risk before the tooth leaves our facility.

Batch Destructive Cut‑Up Inspection — Beyond individual NDT, we randomly pull sample teeth from every production batch and perform destructive cut‑up analysis. Cross‑sectioning the tooth allows our metallurgists to verify internal grain flow integrity, case depth uniformity, and the absence of hidden internal discontinuities. This dual‑level inspection approach — 100% NDT plus batch destructive testing — provides the highest practical assurance of structural quality and reliability.

Strict Dimensional Tolerance Control — All critical interface and working dimensions — the J700 adapter nose pocket profile, retention pin slot location and width, and the tooth penetration geometry — are machined and inspected within the tolerances of the original Caterpillar engineering drawings. This ensures a tight, secure lock‑up between the tooth and adapter, eliminating the relative movement that causes premature insert wear and preventing tooth loss during aggressive digging cycles.

5. One Manufacturer for Complete Undercarriage and Ground‑Engaging Tools

A bucket tooth is a critical wear part, but it is part of a larger system. HELI‑DSWORD manufactures the full range of undercarriage components and ground‑engaging tools under one integrated quality management system:

• Track rollers (bottom rollers)
• Carrier rollers (top rollers)
• Front idlers (guide wheels)
• Drive sprockets (drive wheel assemblies)
• Complete track chain assemblies with shoes
• Forged bucket teeth, adapters, and ripper tips for excavators and dozers

Because all these components share a unified metallurgical philosophy, heat treatment discipline, and dimensional tolerance regime, they provide predictable, compatible wear performance. For a fleet operating CAT 374, 375, 390, or 995 excavators, sourcing both undercarriage parts and bucket teeth from HELI‑DSWORD simplifies logistics and ensures a consistent, high‑end quality level across all wear items.
