Emuge Corp. has introduced the KSN5 and KSN6 Softsynchro® Tap Holders. The holders are designed for tapping operations in components used in oil, power generation and wind turbine applications and in the production of large diesel, locomotive and ship engines.  

“We are seeing an increased need for larger tapping applications such as in the energy sector,” said Mr. Mark Hatch, Product Director of Taps and Threads Mills at Emuge Corp. “The new KSN5 and KSN6 Softsynchro Series are ideal for work in energy and other large component applications”. The KSN5 series is for tap sizes M16 to M56 and ANSI sizes to 1 ¾”.  

The KSN5 series uses the ER50GB collet and is available in both DIN and ANSI tap sizes. Tension and compression of  2mm is used in machines with rigid tapping cycles. Coolant-through capability is available up to 50 bar and the KSN5 series is also available with an integral shank CAT50 or HSK100A. The KSN6 series is for sizes M24 to M76 and uses Emuge HE2 large QC Tap Adapters used currently on Emuge HF20 tap holders.  Emuge HE2-IKZZ adapters are available in both DIN and ANSI tap sizes 1” through 2 ½”. The KSN6 has 2mm of tension and 2mm of compression for rigid tapping cycles. The tool is coolant-through capable, to a maximum of 50 bar. Emuge KSN Series Tool Holders are designed, engineered and manufactured with the utmost precision and quality and provide excellent concentricity, rigidity and safe tool clamping in machines with synchronous spindles.  Axial forces that occur in the threading process are minimized by the use of an integrated minimum length compensation on tension and compression.
