🔑 Key Advantages:

v  Universal Machine Fit: Universal Machine Compatibility Designed for maximum adaptability; this tap chuck is designed for maximum flexibility across a wide range of machines. It seamlessly fits vertical drilling and milling machines with rotating and reversing spindles, while also being fully compatible with horizontal lathes, CNC, VMC, and HMC setups. Additionally, it supports radial drilling machines, electric tapping machines and Pneumatic Tapping Machine Gun, making it a highly adaptable solution for both traditional workshops and modern automated systems.

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 and CI Casting, and also suitable for Low Carbon Steel.

v  Cost-Efficient Tapping: Enables fast multi-size tapping at low cost with a single tap chuck.

v  User Requirement: For best performance, operation by a skilled machinist & semi-skilled machinist is recommended.

v  High-Speed Output: Enables tapping faster than Hand Tapping Tools and suited for rapid multi-size tapping at low cost.

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 – Model TK/JT:

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.

v  Workpiece Fixation and Tap Alignment – Critical Considerations:

Ø  Secure the workpiece rigidly and firmly prior to tapping. This prevents any movement, ensures precise threading, and minimizes the risk of tool damage.

Ø  Since spindle float is not available, the tap cannot self-align during entry. Therefore, it is essential that the drilled hole is perfectly aligned and matched to the tap to ensure accurate engagement and avoid mis threading.

v  Blind Hole – Drill Depth Recommendation: The drilled hole should be approximately 2 to 3 mm deeper than the required tapping depth. This extra depth provides clearance for the tap's lead-in point, ensuring accurate threading and preventing bottoming out.

v  Tapping Chamfer: A tapping chamfer is necessary to ensure proper thread formation and tool performance during the tapping process. It is the tapered portion at the front of a tap that gradually engages the material, distributing the cutting load across multiple teeth. This taper is essential for reducing stress on the tap, improving alignment, and producing clean, accurate threads.

Ø  The type of hole - Through or Blind - determines the appropriate chamfer style:

Ø  Long chamfers (Type B) are ideal for through holes and offer better surface finish and lower cutting pressure.

Ø  Medium chamfers (Type C) are standard for blind holes.

Ø  Short chamfers (Type E) are used when clearance is limited at the bottom of the hole.

🎯 High-Precision Features:

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: 75–400 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 ]

v  L/R Nut Square Sizes: 

Model	L/R Nut Square (mm)	L/R Set, Approx Weight (Kg.)
TK-1	13.60 [14 mm]	0.030 Kg.
TK-2	17.70 [18 mm]	0.080 Kg.
TK-3	13.60 [24 mm]	0.200 Kg.
