Tooth Holder

Customized Forged Tooth Holders – Secure Interface Between Teeth & Auger Flights

At Y&J Industries, we manufacture high‑performance tooth holders that serve as the critical interface between the cutting teeth and the auger flights. Every tooth holder is fully customized – produced strictly according to your drawings or physical samples. The design is created by you or your engineering team; we focus on precision manufacturing to bring your design to life. These components use either pin‑lock or taper‑fit systems to ensure stability and prevent tooth loss under high torque, heavy loads, and abrasive drilling conditions.

Die Forged & Made to Your Drawings or Samples

All tooth holders are produced using die forging (closed‑die forging) for superior grain flow, impact resistance, and dimensional consistency. The standard material is 42CrMo – a high‑strength alloy steel known for excellent toughness and fatigue resistance. An optional welding overlay can be applied to critical wear surfaces for extended service life in highly abrasive ground. Y&J Industries is a Chinese manufacturer specializing in customized construction machinery parts through integrated casting, forging, and machining. Simply provide your drawings (PDF, DWG, STEP, or other formats) or send us physical samples, along with required dimensions, material grade, and whether you need the welding overlay. We replicate your part with high precision and strict quality control. There is no fixed minimum order quantity – we adapt to your batch size, whether small or large. Tooth holders are available in various sizes to fit different auger diameters and torque requirements.

Pin‑Lock vs. Taper‑Fit – Choose Your Retention System

Your design can specify either system – we produce both exactly as you require:

• Pin‑Lock System: Uses a hardened steel pin to secure the tooth to the tooth holder. Simple field installation and removal, ideal for applications where teeth are changed frequently.
• Taper‑Fit System: Provides a self‑tightening interference fit that increases retention under rotational torque. Excellent for high‑vibration, high‑torque drilling where zero movement is required.

Both systems are forged from 42CrMo and machined to precise tolerances, ensuring a stable interface between your teeth and auger flights.

Installation & Maintenance – Maximize Service Life

Proper installation is critical: clean all mating surfaces, align the tooth holder correctly with the auger flight, and secure the pin or fully seat the taper. Regularly inspect the tooth holder for wear, especially around the locking mechanism and the welding overlay (if applied). Replace the holder before excessive play develops – this protects both the tooth and the auger flight from damage. Y&J Industries combines metallurgical know‑how with strict quality control to meet international standards, serving clients in more than forty countries.
