The KST Series tapping machine from King Sang provides fully automatic tapping with easy change of thread-pitch gears. Safety stop devices enhance operator protection, while horizontal gear construction reduces noise and maximizes tapping consistency, making it suitable for a wide range of threaded assembly applications.
King Sang Horizontal Gear Type Automatic Tapping Machine (KST Series)
King Sang’s Horizontal Gear Type Automatic Tapping Machine combines durable gear-drive mechanics with reliable tapping performance. With variants like KST-204A, KST-224A, and KST-232A, it supports diverse tapping capacities and industrial workloads with precision and repeatability — improving throughput in fabrication and production lines.
Features
Allows easy swapping of thread-pitch gears, reducing wear and improving precision. Less slippage, better thread quality over long production runs.
Enhances operational safety by stopping the machine in case of overtravel or other unsafe conditions. Prevents damage to threads and tooling.
Three models (204A, 224A, 232A) with increasing quill diameters (Ø42 → Ø85 mm), spindle tapers (JT2, MT2, MT3), and tapping size capacities (from Ø1-8 mm up to Ø8-32 mm). Allows choosing machine matched to required workpiece size and thread.
Motor power ranges: from ½ HP 4-pole, 1 HP 6-pole up to 2 HP 6-pole depending on model; speed varies with frequency (50Hz / 60Hz) and model, allowing flexibility.
Despite being automatic tapping machines, the KST series has manageable foundation area (about 165×205 mm up to 215×282 mm) and reasonable weight (50–125 kg depending on model), with table sizes suited for moderate workpiece holding.
