Every month, we’re putting together a Technology Showcase, highlighting some of the product information that PM receives from supplier companies. For October, we focused on toolholders — which are important for effective, safe connections between high-speed tools and machines. With the right toolholder, companies can safely and consistently produce quality, reliable products.
PM’s October toolholder showcase includes a pre-settable, quick-changeable tooling system for swiss-type lathes; a toolholder system that has clamping carried out via a clamping wedge on the face; a height-adjustable backworking holder offering precise coolant delivery; and more as described below.

Goeltenbodt, represented in the U.S. by Schwanog, offers a pre-settable, quick-changeable and coolant fed tooling system for Swiss-type automatic lathes such as Tsugami, Star, Citizen, Tornos and others. The system is said to provide quick and easy tool changeovers and is pre-settable off the machine with repeatability of .0004″. Coolant-fed holders with high pressure ratings up to 1,500 psi are available.
Horn Supermini Set Offers Greater Holding Force

Paul Horn GmbH offers users its Supermini toolholder system with face clamping as a set. With the Supermini holder variant, clamping is not carried out via the lateral surface of the cutting insert but rather via a clamping wedge on the face. This is said to result in a greater holding force on the insert and thus high rigidity of the entire system. Also, this style of clamping is said to increase repeatability when changing the insert and provide better utilization of the available space. This is said to be a great advantage on Swiss-type lathes, as the user can change the cutting insert without removing the toolholder.
GenSwiss Quick-Change Toolholder Adapter for Fast Setups, Tool Changes

GenSwiss’ GenQuick quick-change ER system for CNC Swiss machines and precision machining equipment has been redesigned to achieve faster setups and tool changes. It does this through the use of toolholder adapters and quick-change modules that can be preset and are based on the ER standard toolholding system. Base toolholder shanks are available from GenSwiss in diameters to suit most Swiss machine models’ ID working tool positions.
Backworking Holders Designed to Reduce Setup Time

The iSwiss Corp.’s Height Adjustable Backworking Holder X Type is said to offer precise coolant delivery to the cutting area up to 130 bars (1885 psi). It has been redesigned to point the coolant flow directly to the tip of the tool, which is designed to aid in evacuating the heat from the cutting area and breaking the chips. The system is built more rigidly to eliminate vibrations (up to 80%), which is said to help increase tool life and to achieve better surface finish. These holders are intended for Star, Citizen, Tornos, Mazak, Tsugami, Hanwha, Traub and Manurhin machines.
Iscar Neo Swiss Quick-Change Toolholders for Swiss-Types

Iscar’s NEO Swiss modular quickchange tooling line for Swiss-Type machines are designed to provide rigidity and accuracy. The line is said to have a robust rotary wedge mechanical design for clamping rigidity. The company says rigidity is important due to the nature of the processes on Swiss machines and the difficult materials which are often machined, meaning that depths of cuts can be deep which can compound the need for an extremely rigid system. Accuracy is also essential when changing tools for part requirements and achieving seamless changeover from job to job. The repeatability of Iscar’s NEO Swiss tools is ±.0008” (±0.02 mm).
Thinbit Toolholders Position Inserts at Multiple Angles

Kaiser Tool Co.’ s Thinbit angled round toolholders are designed for CNC, conventional and endworking positions on Swiss screw machines. The angled round toolholders position the insert at 30-, 45- or 60-degree angles for reliefs, undercuts and angled outer diameter and face grooves. Round shank sizes are available in diameters of 1/2", 5/8", 3/4", 1", 20 mm and 25 mm. The angled round toolholders are for use with Thinbit inserts in grades for ferrous and nonferrous materials. Inserts are available in sizes 0.004" to 0.150" which come in 0.001" increments coated with TiN, TiAlN, TiCN, diamond film or uncoated.
