Rubber Collets :- S151, S161, S171, S212, S222, S232, S413, S433, S453, S613, S623
📌 Purpose:
A rubber collet is a type of work holding device used in machining and tooling applications. Unlike traditional steel collets, it combines rubber and metal segments to provide a flexible yet firm grip on workpieces. This hybrid design allows it to accommodate a wider range of diameters typically ±1mm from the nominal size making it ideal for operations where frequent size changes occur.
🏗️ Machine Compatibility:
Model Rubber Collet can be seamlessly mounted on:
v Taco Products – HR, TK/JT, TK/MT
v Centre lathes
v Capstans and turret lathes
v Semi-automatic machines

Rubber Collet
Engineered for reliability, speed, and precision in high-performance tapping operations.
🔑 Key Advantages:
v Universal Machine Fit: Universal Machine Compatibility Designed for maximum adaptability; this rubber collet fits Reversible Tapping Attachment (HR) and Non-reversible Tapping Attachment (HNR). It's also fully compatible with Tap Chuck (TK) and Pneumatic Tapping Machine, as well as CNC and VMC machines, making it a go-to solution across conventional and automated setups.
v Tap Compatibility: Accepts all standard HSS tap sets and non-standard HSS taps, only the proper tap length is required.
v Material Suitability: Optimized for ductile metals like MS, CI Casting, Low Carbon Steel, Aluminium and Copper, and also suitable for Steel.
v Machining bar stock with varying diameters: Their ability to grip a range of sizes (typically ±1mm) makes them ideal for jobs where material tolerances fluctuate.
v Quick Changeovers: Because one rubber collet can replace several standard collets, they’re a favourite in setups where time and tooling costs matter.
v User Requirement: For best performance, operation by a skilled machinist & semi-skilled machinist is recommended.
v Maximum Holding Capacity: Provides greater holding capacity than Tap Adaptor QA and ER collets, making it ideal for rapid, cost-effective multi-size tapping
v Die Holder Model DH – Versatile Threading Solution: The Die Holder Model DH transforms a standard tapping attachment into a high-efficiency threading tool with a simple die-holder insertion. This smart integration enables dual-purpose functionality tapping and threading without changing machines. It’s a cost-saving, space-efficient choice for any machine shop aiming to boost productivity with minimal setup.
⚡️Quick & Easy Installation – Rubber Collet:
v Insert the tap into the attachment's chuck and align it properly.
v Lightly tighten the square nuts to hold the tap squarely in place.
v Secure the tap by tightening the chuck nut this grips the tap firmly via the collet.
🎯 High-Precision Features:
v Wider clamping range: Each rubber collet can typically handle a ±1mm range from its nominal size, reducing the need for frequent tool changes.
v Higher gripping force: Thanks to their vulcanized rubber-metal construction, they exert uniform pressure along the entire contact surface up to 2–3 times more than split-steel collets.
v Cost-effective: One rubber collet can replace multiple standard collets, cutting tooling costs by up to 50%.
v Ideal for tapping: Their flexibility and strong grip make them perfect for rapid multi-size tapping, especially in high-mix, low-volume production environments.
v Production-Ready: Capable of handling both batch quantities and mass production with ease.
v Rubber Collet System: Equipped with a precision rubber collet and adjustable left/right locking nuts, the attachment accommodates all standard tap sizes within its rated capacity. This ensures a secure grip, minimal vibration, and optimal tapping accuracy.
📐 Technical Operating Range:
v Threading Speed: 300–1000 RPM depending on material and tap condition (Always use coolant for finish-grade threads and longer tap life.)
v Material Hardness: 50–60.5 HRA, 81–97 HRB, 0–20 HRC, [ Rockwell ]
v Max. Tapping Depth: Up to 3× to 4× the tap diameter. [ Length × Diameter ]
🛠️ Maintenance Note:
To extend the life of this tapping attachment or any die head, die holder, or tap chuck avoid constant use at upper or lower limit capacities. Consider rotating between two or three units for heavy-duty applications.
