Floating tap holders with extension and Morse taper shank are a reliable technical solution for threading operations on machine tools. They are designed to ensure high thread quality, extended tool life, and effective compensation of synchronization errors during machining. They are particularly suitable for use on single-spindle and multi-spindle lathes, CNC machining centers, drilling machines, and transfer lines.

The operating principle is based on a floating system with controlled extension stroke (E = 16 mm), allowing axial movement of the tap through internal springs. This axial movement compensates differences between machine feed and thread pitch during machining, preventing tool overload and significantly reducing the risk of breakage.

During reversal phases, typical in tapping operations, the axial compensation absorbs generated stresses, maintaining stable working conditions. A slight controlled radial play further compensates misalignment between spindle and workpiece, improving thread quality and reducing geometrical errors.

The different dimensional configurations allow use with various tap diameters, maintaining the right balance between system rigidity and compensation capability. This makes the tap holder versatile and suitable for a wide range of industrial applications.

From a construction standpoint, the tap holder is made from certified high-alloy steel, heat-treated and fully ground to ensure wear resistance, geometric precision, and long-term stability. The entire production process is carried out in Italy using high-precision machine tools and strict quality control procedures.

These tap holders are widely used in automotive, industrial production, precision engineering, and subcontract machining. They are ideal for production cycles where thread quality, reduced scrap, and extended tool life are critical factors.

Selection should consider taper type (Morse taper), tap diameter, and operating conditions, especially in threading processes requiring synchronization compensation. This is a reliable and versatile solution for technicians, CNC operators, and process engineers.
