Product Detailed Description
Our integrated threading system combines the 60° ISO Metric Threading Insert Series with SER (right hand) and SEL (left hand) tool holders, engineered for high-precision internal and external metric thread machining. Adhering strictly to ISO standards (ISO 60° mertic thread), the threading inserts deliver consistent thread accuracy, while the SER/L tool holders ensure stable clamping and rigid support. Suitable for CNC lathes and turning centers, this system covers a wide range of metric thread sizes (M1-M60), making it ideal for machining steel, alloy steel, stainless steel, and cast iron in automotive, mechanical engineering, fastener manufacturing, and precision machining industries. The carbide threading inserts and holders work in perfect harmony to ensure long service life, efficient chip control, and burr-free thread finishes.
Model Breakdown
A. 60° ISO Metric Threading Insert Series
Inserts are available in two types: ER (External Threading) for external thread machining and IR (Internal Threading) for internal thread machining, with consistent 60° ISO metric thread. Typical model example: from 11ER to 27ER(external) / from 11IR to 27IR (internal)
B. SER/L Threading Tool Holders
Two types of holders for internal/external threading: SER (right hand) and SEL (left hand), designed to perfectly match the 60° ISO threading inserts. Typical model example: from SER1212 to SER4040 (external) / from SEL1212 to SEL4040 (internal)
Core Advantages
1. 60° ISO Metric Threading Insert Advantages
Standard 60° ISO Metric Profile: Strictly conforms to ISO standards, ensuring thread accuracy and universal compatibility with metric thread workpieces. Suitable for all standard metric thread sizes (M1-M60, pitch 0.5mm-6.0mm).
Premium Carbide Substrate: Crafted with carbide, balancing hardness (HRA 92.5) and toughness. Resists wear and thermal shock.
Internal/External Dual Options: ER inserts for external threads (e.g., bolts, shafts) and IR inserts for internal threads (e.g., nuts, holes), covering all common threading scenarios. Multi-pitch options meet diverse machining needs.
Efficient Chip Control: Integral chip-breaker groove design optimizes chip evacuation, preventing chip clogging and reducing heat buildup. Ensures burr-free thread finishes.
2. SER/L Threading Tool Holder Advantages
Precision Alloy Steel Construction: Made from carbide material, heat-treated for high rigidity and wear resistance. Prevents holder deformation under cutting loads, ensuring consistent insert positioning.
Secure Clamping System: Ensure the insert stays firmly in place during high-speed threading, eliminating vibration and thread deviation.
Internal/External Specialization: SER holders (external) feature an optimized tool angle for clear chip evacuation during external threading; SEL holders (internal) have a slim, extended design to access deep internal threads.
Universal Compatibility: Standard rectangular shank (16×16mm, 20×20mm, 25×25mm......) fits all CNC lathe turrets. Compatible with all 60° ISO ER/IR threading inserts of matching size
Application Scenarios
External Threading: Bolts, screws, shafts, automotive transmission parts, and fasteners (using SER holders + ER inserts).
Internal Threading: Nuts, threaded holes, hydraulic cylinders, engine blocks, and pipe fittings (using SL holders + IR inserts).
High-Volume Production: Fastener manufacturing (nuts, bolts), automotive component machining, and mechanical hardware production.
Precision Machining: Aerospace components, medical equipment parts, and precision instrument threaded features requiring class 6H/6g thread accuracy.
