NTK Cutting Tools is releasing its Stick Duo Splash cartridge insert line for the turning of small parts. Stick Duo Splash inserts direct high-pressure coolant at the cutting edge, helping to overcome the issues of poor swarf clearance when machining small parts that require internal turning and threading operations.

The Stick Duo Splash is available in two variants that offer either a single coolant outlet directed to the tip of the insert or, alternatively, a two-outlet holder which delivers cutting fluid to both the front and rear side of the tool insert. Stick Duo Splash inserts with two coolant outlets have been designed for evacuating chips during the processing of blind holes, while the single coolant outlet tool is suitable for the machining of through-holes and bores.
NTK’s Stick Duo Splash tool-holder cartridge has been developed for use with machine tools that have both standard and through-coolant delivery configurations. However, the flexibility of the Stick Duo Splash allows end users to attach the coolant hose to either a screw hole at the rear end of the cartridge, or via a connection point located at the front end. NTK has developed the Stick Duo Splash with two coolant inlet options to meet the various tooling configurations and set-ups of small turning centres and sliding-head machines with compact work envelopes.
Stick Duo Splash is available with a variety of cartridge dimensions that meet the specifications of all modern turning machines. Available diameters include 16, 19.05, 20, 22, 25 and 25.4 mm, with an overall length of 90, 110, 120 and 125 mm.

ElectroMill diamond and CBN electroplated grinding solutions from Engis are designed to replace expensive, complex, tungsten carbide or PCD milling cutters in the production of high-quality, flat milled surfaces in high-volume applications – even those with an interrupted cut or where multiple materials must be machined simultaneously.

Designed for use on a variety of machining centre types, in fact any system with high pressure coolant and 10,000+ rpm spindle, ElectroMill improves surface finish and flatness, while extending tool life and reducing cost per part, says the company.
ElectroMill solutions are offered either as an integral unit, providing increased rigidity and internal balance, or as a multi-part (shell) design, offering more flexible options and adaptability for legacy tool-holding situations. A number of standard taper options are also available.
The major benefits of the Engis ElectroMill include reduced numbers of operations, set-ups and inspections, along with high stock removal rates and low heat build-up (providing stress-free, cool cutting action). Engis says that ElectroMill extends tool life compared with conventional milling cutters because the diamond stays sharp with constant controlled micro-fracturing and no dressing cycles required. In addition, the ElectroMill solution is environmentally friendly, being usable with water-soluble or synthetic coolants.
The ElectroMill is aimed at sectors that include marine, automotive, aerospace and defence – and at a wide variety of components in ferrous, non-ferrous and exotic materials.

A new co-operation agreement between two German companies, tool manufacturer Horn and lathe tool-holder producer W&F Werkzeugtechnik, aims to offer customers complete solutions covering everything from the spindle to the tool cutting edge.

Initially, the collaboration will focus on quick tool-change systems for sliding-head lathes and internally cooled whirling units. Under the deal, W&F tool solutions will be sold worldwide by Horn through its subsidiaries and sales partners in more than 70 countries. The UK subsidiary, Horn Cutting Tools, is located in Ringwood, Hampshire.
