Walter AG

The solid carbide high-performance drills from the X•treme product range represent maximum productivity, process reliability and a wide range of applications. With this most recent addition, a version with external cooling, Walter has now made this successful range of tools complete. The X•treme solid carbide high-performance drills are now immediately available in the diameter range 3 to 25 mm including external cooling. Apart from the cooling method, they offer users the same advantages as the already tried-and-tested version with internal cooling. The most striking feature is the four lands. The improved guidance ensures maximum process reliability and extends the area of application.In many cases, the processing time for components is reduced, as the user is able to forgo preparatory operations such as milling a plane surface.
In response to very positive customer feedback about Tiger∙tec® Silver high-performance cutting material, Walter are adding a new grade to the Tiger∙tec® Silver family. The universal WKP35S grade is joined by WKP25S, a grade whose main area of application is the machining of steel and castings. The newly developed Tiger∙tec® Silver WKP25 S milling/cutting material is designed to process all steel materials at high cutting speeds as well as average feed rates. This also applies to tool steel with strengths >1000 N/mm2. Its second main area of application lies in the machining of grey cast iron or cast iron containing vermicular graphite at average to high cutting speeds and average feed rates.The new grade is a match for unfavourable conditions such as fluctuating material removal or severely interrupted cuts. Typical components that can be machined using WKP25S are in series production.
The success of the Xtra•tec® Insert Drill has led Walter to supplement the product range even further. The larger diameter range of 13.5 mm to 120 mm is now available with immediate effect and is suitable for hole depths up 5xD. The expansion of the Xtra•tec® Insert Drill programme concerns both sides of the diameter spectrum. Diameters as small as 13.5mm are now available in contrast to the 16.5mm versions available previously. The tools in this range are equipped with size 1 internal and external inserts. The expansion of tools larger than 59 mm is particularly extensive. Walter markets the insert drill as a cartridge solution in this size range. This provides the user with cost advantages in comparison to a solution with fixed insert seats.Walter offers the drills up to D=80 mm and 3xD hole depth as a standard version, up to D=120 mm and 5xD hole depth as a special version or semi-standard version via the Walter Xpress service.
In comparison with conventional drills made of HSS, the new Titex UFL® gives you significantly more performance, especially when drilling deep holes. The particular identifying feature is its ultra flat flute profile. The core diameter is larger than that of a standard type N twist drill, which results in higher rigidity. This design was made possible through the use of a helix angle of 40 degrees – the standard helix angle is 30 degrees. Additional features include a special U form tip geometry for low feed forces as well as a TFP tip coating for maximum tool life. An HSS-E grade cutting tool material with 5 percent Co content and high temperature resistance is used to achieve this. The new high-tech HSS-E drill is suitable for all ISO material groups. Walter recommends this tool especially for users who, because of the quantity, need a universal drill that's capable of making deep holes.The diameter range available is from 1 to 12 mm.
Walter is expanding the clamping options for the ConeFit™ modular milling system by introducing new monoblock toolholders. The greater stability pushes the performance of the mill even closer to the limit. With these new monoblock toolholders, Walter is now offering users of the ConeFit™ modular milling system an option with as few joins as possible. The toolholders that have the special ConeFit™ thread fit directly into the machine spindle and this means that there is no need for the usual cut-off area between the modular tool shank and the collet. At 2xD, the clamping length of the mill is extremely short. The entire tool/clamping system therefore maintains an excellent level of stability. During machining, extremely high cutting data can be achieved and the performance of the tool can be used to its full extent. In order to reach as many users as possible, the monoblock toolholders come in various versions to fit the most common machine spindles on the market. In the area of milling machines/machining centres, the HSK 63A, SK40, MAS BT40 interfaces are covered, and in the area of lathes with driven tools, the Walter Capto™ C5 and C6 adaptors are covered. We recommend this new clamping option for applications that do not have protruding edges.If these are present, the tried and tested steel and solid carbide shanks are available as an alternative and come in different lengths.
Since their launch, a great number of additions have been made to the Xtra•tec® Point Drill range of drills with replaceable tip. Walter regularly meets many customer requirements for new diameters or hole depths. This development is continuing: The upper limit for the hole diameter is now 38 mm. Xtra•tec® Point Drills are one of the top-of-the-range drills on the tools market in terms of performance and hole quality. This is primarily due to the ground replaceable tips made of Tiger•tec® cutting tool materials, the high-precision prism seats in the drill body and the rocksolid setting. In the diameter range of up to 24 mm, the 10xD variant (type designation B4010) now reaches depths within the deep-hole range. The variants for hole depths of 3xD, 5xD and 7xD (type designations B4013, B4015 and B4017) were previously available for hole diameters of up to 32 mm. This is where additions to the range come into play and many users from the fields of mechanical and plant engineering and related industries have been waiting for these additions: The 38 mm hole diameter is now the new upper limit for depths of up to 7xD. The range between 32 and 38 mm is covered by a large number of significant intermediate sizes. For this extended diameter range, Walter is initially supplying the 6003 type replaceable tip for stainless steel grades, materials with difficult cutting properties and long-chipping structural steels. Other replaceable tips in these hole sizes will follow. The features of the 6003 type include a PVD mono-layer coating on a titanium aluminium nitrite base, accommodated to the materials mentioned above. Two further properties are significant, especially for drilling large diameters: a light entry and as soft a cutting action as possible, which also makes it possible to use the drills on low-performance machines.These properties were incorporated by, for example, including a moderate rounding of the cutting edge and a particular point thinning design.
Only one year on since the market launch of the highperformance cutting tool material Tiger•tec® Silver and Walter has completed the range of indexable inserts for the whole range of mills used for steel and cast iron machining. "In view of the extraordinary performance increases made through Tiger•tec® Silver, we have set ourselves an ambitious goal: to equip all mills with the new cutting tool material as soon as possible - the user should benefit from the advancement in performance of the new cutting tool material as quickly as possible. It's full speed ahead for our indexable insert manufacturing“, explains Michael Fink, Product Management Director at Walter AG. In many cases, the performance increases achieved by the silver tiger teeth are up to 100 percent. This is the case, for example, for the face milling of guide tracks made of ST52-2 using an Xtra•tec® octagon cutter F4080. The user has confirmed that the tool life has doubled. Tiger•tec® Silver has superseded a previous benchmark cutting tool material. As the Tübingen-based carbide specialist has announced in the meantime, Tiger•tec Silver indexable inserts are already planned for drilling and turning. Developers are currently working on extending the cutting material grades.The current universal insert grade WKP35S is being strengthened through grades with a greater level of toughness as well as even higher levels of hardness.
The most striking feature of the new Walter Titex X·treme solid carbide high-performance drills is their four lands; the previous generation only featured two. The improved guidance enhances process reliability - and not just in non-critical drilling situations. In particular, the tools maintain their direction at the drill entrance or exit, even when machining inclined surfaces. This enhancement expands the area of application. In many cases, the operating time for components is reduced, as the user is able to forgo preparatory operations such as milling a plane surface or drilling pilot holes. The four lands also ensure a better hole surface. Another new feature is the XPL aluminium chrome nitride-based coating. This coating currently represents the highest level of development for solid carbide twist drills. It enables universal use of the tools for all ISO material groups. The user benefits from a maximum tool life. Other features of X·treme drills include internal cooling, a 140 degree point angle and an HA or HE shank according to DIN 6535. The h6 shank tolerance enables seating in shrink fit chucks.Walter is launching the new generation of drills in diameters ranging from 3 to 25 mm with an internally cooled configuration according to DIN 6537 long. The length/bore ratio according to this standard is around 5xd. Additional designs and dimensions will be introduced gradually.
Like the already familiar PVD-Al2O3 grades from Walter, the two new cutting materials WSM 20 and WSM 30 also have excellent toughness. In addition, the multilayer coatings for the two cutting tool materials feature increased wear and temperature resistance that put all other PVD coatings on the market in the shade. As a result the PVD-Tiger is also conquering new applications that in the past were still closed to it. The above mentioned coating properties provide ideal protection for machining materials with difficult cutting properties and high-alloy materials (ISO S and ISO M). With materials like Inconel 718, Hasteloy or also stainless, austenitic CrNi steels, the two newcomers are in their element.Thanks to the special Tiger.tec(r) process, WSM 20 or WSM 30 indexable inserts have very sharp cutting edges and smooth rake faces.
Walter is careful not to miss an opportunity, also not in the solid carbide high performance roughing milling cutter sector. After various optimisations of the Walter Prototyp Protostar(r) Qmax HR milling cutter family, a new variant for machining steel is now on the market in the form of the Qmax HNR. The Qmax-HR series was designed specially for machining stainless steels. A deep, thread-like tooth pattern and several helix angles (30, 40 and 45 degrees) provide the best pre-conditions for this task. Conversely, the new Qmax HNR is a specialist for mild steel, alloy steel and tool steel. The roughing tooth pattern on this version is flatter than on the HR models. This feature provides particularly stable cutting edges. A helix angle of 30 degrees also maximises the stability of the tool. The other features such as a new type of carbide substrate, refined macrogeometry and microgeometry, and special edge preparation have been adopted from the HR types.The result is an enormous performance increase when used on the materials stated.
