Manufacturers should choose Coromant EH as the preferred rotating modular interface for applications up to 32mm (1.256in) in diameter. Integrated machine adaptors with EH coupling are recommended for small interfaces where gauge line and swing diameter are critical (BT30, SK40, HSK40/50/63, ER, DTH), as well as different shank types in long overhang applications up to 35mm (1.38in) diameter.

Sandvik is implementing a unique cemented carbide recycling program. It will provide huge benefits to customers, local communities and the planet.

CoroMill 316 is suitable for all general milling operations, including high-feed face milling, slot milling, helical interpolation, shoulder milling, profile milling and chamfer milling. The exchangeable heads allow users to easily and accurately switch between various operations, creating end mills with optimised radius variation, teeth frequency, geometry and grade. Beyond steel and stainless steel, the tools can also be used successfully on ISO K (cast iron) and ISO S (heat resistant super alloys) materials.

The cemented carbide recycling program is the only program of its kind in the world. It has been made possible through two major developments by Sandvik; extraction units that separate used cemented carbide inserts from the steel body of drill bits at customer sites, and a process for creating premium cemented carbide powder from the recycled material.

Making new inserts from recycled material significantly reduces the need to mine resources. This means that energy use is reduced by 70 percent and 64 percent less CO2 is emitted. It also means that Sandvik doesn’t have to worry about tungsten supply, a scarce and finite material.

“The latest generation of CoroMill 316 adds a longer cutting length to its list of attributes, delivering even greater flexibility for machine shops,” said Tiziana Pro, product manager solid end mills at Sandvik Coromant. “Specific operations to benefit includes those that demand higher axial depth, up to 1.2 x Dc, as well as where high stability and vibration suppression are required. In particular, the combination of the modular Coromant EH system and CoroMill 316 provides a number of solutions for all types of machines and user challenges.”

The program is currently being rolled out across all Sandvik Mining and Rock Solutions customer sites around the world. Sandvik produces tens of millions of inserts every year. It has a target to buy back 90 percent of this volume from its customers. By reusing the recycled material in new tools, the company will achieve 90 percent circularity with cemented carbide.

The local extraction units are the key to the program. “We used to have to ship the entire drill bits to facilities around the world,” says Kangleas. “And the extraction of the cemented carbide then required a very unsafe and energy intensive process. By doing this in a safe and efficient way at the point of use we now only transport the material we need. This significantly reduces our transport emissions. We can also provide jobs on the local extraction units to people in the local communities.”

Solid Round Tools are purpose-designed to support workflow, efficiency and productivity, with each cutter positioned within three product categories: versatile, optimised and customised. Versatile solutions are performance-oriented tools based on maximising flexibility and cost efficiency for the customer, while optimised solutions comprise a unique line of refined tools for specific needs where extreme efficiency, reliability and durability are paramount. Customised solutions are designed individually to meet the highest performance demands.

The new CoroMill 316 generation of exchangeable-head milling cutters from Sandvik Coromant enhances the company’s established Solid Round Tools portfolio by bringing higher levels of versatility and productivity to machining operations in ISO P (steel) and ISO M (stainless steel) materials. Further benefits include high reliability in almost all applications, along with enhanced tool life and a silent machining process.

CoroMill 316 is part of the extensive Solid Rounds Tools offer from Sandvik Coromant, which today includes more than 10,000 standard products to cover all applications within the areas of solid carbide drilling, milling, tapping, reaming and threading.

“We want the inserts back,” says Dean Kangleas, VP Product Line Services at Sandvik Rock Tools Division. “And the program brings many benefits to customer too. First of all we are buying back the inserts from customers, so we are paying for them. And by separating the cemented carbide from the drill bit the steel value also increases. As we do this on site, customers can then sell the scrap steel to local scrap dealers for a premium. It’s a win-win.”

“It’s good for local communities because with the extraction units we can create local jobs and it is good for the planet because by mining less tungsten and using less virgin material we use less resources and emit lower amounts of CO2. And it is good for Sandvik because it is a cost save. We can produce the same quality drill bits with a lower material cost. It is just good for everybody,” says Kangleas.

Tungsten is a key component in cemented carbide and the extracted inserts are being sent to the Sandvik owned Wolfram Bergbau und Hütten AG tungsten plant in Austria. A new process is used to turn the recycled cemented carbide into powder that has the exact same premium quality as that produced from virgin material. It is then used to manufacture new inserts.
