The quality standards in milling have been defined by the Boehlerit cutting experts for decades now. The development engineers in the Austrian steel industry town of Kapfenberg put all their technical know-how into a dynamic FEM design (finite-element method) for Boehlerit milling equipment to create stable milling tools with excellent fatigue strength properties, optimum chip formation and precise concentricity characteristics. All tools are nickel-implanted and owe their long tool life to special materials and heat treatments. The basis of the new high-end milling range are 15 innovative tool systems, including multi-purpose tool systems where one base body makes two types of machining possible. This reduces the carrier body costs and saves warehousing expenses. The range includes highly economical high-feed tools and face-milling cutters with 16 edges. A total of 18 milling grades cover all the many milling tasks of face or step milling in all current materials. They combine machining reliability and economic efficiency. Various carbide substrates are used to produce the range of milling grades, or indexable milling inserts, fine-tuned to cover an extensive range of face and step milling operations: from roughing to finishing, from cast to steel, stainless materials and aluminium. The milling grades guarantee minimal wear on free areas and a higher resistance to chipping of the cutting edges. Resistance to thermal cracking or crater wear is also ensured.
Regardless of whether it is a roughing application or face milling on low-performance machines: Boehlerit offers four different face milling systems that cover the high demands of our customers through the optimal pairing of design, cutting materials and costs per cutting edge. For high machining volumes, Boehlerit also offers the option of choosing from one of two available high-feed milling systems in order to achieve high economic efficiency.
A multitude of machining possibilities requires a multitude of solutions. Based on many years of experience in the milling sector, Boehlerit has developed seven edge milling systems to date in order to be able to offer the optimal solution for each application. Thanks to the multifunctional nature of some milling systems, the range of applications can be increased, thus reducing costs, by simply changing the indexable insert.
High feed cutting
Boehlerit's tool specialists have been relying on international quality standards in the field of milling for decades. Thanks to their expertise and experience in material and cutting tool development, the experts at the Kapfenberg-based company have developed stable milling cutters with excellent fatigue strength properties, optimum cutting performance and precise geometric characteristics. The BETAtec 90P Feed tools are actually the ultimate corner milling tools in Boehlerit's milling range. The fact that the carrier tools can also be equipped with indexable inserts for high feed milling makes the tool systems multifunctional. This increases efficiency and flexibility for the user and reduces carrier tool costs and the associated storage requirements. The innovative DELTAtec 90P Feed tool system also allows maximum tooth feed rates and can be used both as an HFC milling cutter and as a corner milling cutter. The multifunctional tool systems are available as slip-on, screw-in and shank milling cutters and, in combination with the right cutting material grade, can be used across the entire material group.
THETAtec 25N Feed:
High feed cutting redefined
Boehlerit has already set standards with its positive high feed systems. The company is now expanding its portfolio of high feed products and introducing its new tool concept on a negative basis. Like its positive systems, the innovative THETAtec 25N Feed tool system enables higher cutting rates and thus maximum performance and efficiency in a single application.
High-performance cutting (HPC) is a proven method for performing machining operations with high removal rates, as required for roughing steel, cast iron and stainless materials. Maximum feed rates reduce machine occupancy times and maximise the volume of chips removed. This is advantageous in view of the increasingly important cost factors in the area of process energy efficiency and creates additional production capacity. High-feed milling results in increased productivity and, at the same time, a measurable reduction in costs.

With the DELTAtec 90P Feed, the company already has a versatile milling system in its portfolio and is now adding smaller-format tools. The BALLtec copying tool was specifically developed for finishing - resulting in two new geometries, one for pre-finishing (N geometry with neutral rake angle), the other for fine finishing (F geometry with positive rake angle). The hardness and toughness behaviour of the newly developed grade BCH13M offers special properties in machining. This also brings with it a new geometry with convex helical cutting edges, and fits into the BALLtec programme with the designation FHF2. These tools may also be combined with the Vidat vibration-dampening extension system by Boehlerit technology partner Bilz. Solid carbide extensions by Boehlerit may also be used. The BALLtec carrier tools are available in a high-precision steel design and in a version with a solid carbide shaft.
The RHOMBICtec milling system is also suitable for finishing, but within a larger diameter (16 to 25 mm), and is suitable in particular for 90-degree, plane surface, and contour finishing in die and mould making applications.The ISO 00P programme for roughing applications is also a complete novelty. The programme is extensive and contains a multitude of round indexable inserts for the machining of a wide range of steels as well as cast materials.When developing these three tooling systems, the Kapfenberg-based carbide and tool experts focused on performance as the key element.
And the new cutting grades can certainly hold their own in this respect, for instance the extremely hard, ultra-fine grain grade BCH03M with a cobalt content of just 3 percent, which, in combination with the RHOMBICtec system, is ideal for the finishing of even the hardest materials (up to 65 HRC). This grade is also available for the ISO 00P. Two grades that were specially developed for die and mould making complete the product range: BCH05M is CVD-coated and, in combination with ISO 00P, particularly suited for high-feed applications thanks to its stable cutting edge. The universal BCH10M grade is also available for BALLtec, RHOMBICtec and ISO 00P.
Boehlerit now offers a full-scale solid-carbide milling programme: with innovative technology and versatility, the Austrian carbide and tool specialist raises the bar for the entire industry, all the way to the most challenging machining applications.
The solid-carbide milling portfolio compiled by the Boehlerit cutting material specialists once more focuses on quality and performance, with a carefully thought-out blanks concept on the one hand and high-grade substrates and coatings on the other. This includes PVD coating as well as solid-carbide milling cutters with diamond coating, used for the machining of materials with a high silicon content. Given this level of versatility, there are virtually no limits to possible applications. For roughing applications with large cutting depths, for instance, the programme includes soft-cutting milling tools that require only little machine capacity. These tools are available in diameters from 3 to 20 mm and stand out for their high performance and long lifespan. In addition, the Styrian material specialists also offer standard solid-carbide milling cutters with a special substrate for machining hard materials of up to 58 HRC. Hardened materials (up to 65 HRC) pose an even greater challenge for tools: with this in mind, the Boehlerit developers have also included highly wear resistant solid-carbide milling tools for tool and mould makers. The solid-carbide range also includes tools for milling softer materials such as aluminium, copper or even plastic.
With over 1000 products, this is Boehlerit's most extensive solid carbide milling programme to date. What they have in common is high performance, resistance and tool life - the characteristics that are expected from a carbide and tool specialist. In addition, it is possible for the customer to quickly realise individual special solutions.
The new milling grade generation BCM35M and BCM40M – Unsurpassed cutting power on stainless steels
Milling stainless steels is one of the most challenging tasks in machining technology. The extreme, sometimes downright contradictory properties of this material class ensure a high level of abrasive wear, suboptimal chip break and chemical reactions with the tool material that may lead to built-up edges and, in extreme cases, to tool breakage. Such high requirements demand a perfectly developed tool concept. With the new grade generation BCM35M and BCM40M, Boehlerit is facing up to the challenge of milling stainless steels. As a result of intense research and development, these grades reflect all technical aspects in an optimised form.
