Walter has expanded its line of Walter Titex X-treme DM high performance micro drills with eight new models, in drilling depths ranging from 2xD to 30xD. Thanks to advances in carbide technology, special coatings and design, these new drills are able to outperform conventional micro drilling tools.
Traditionally, gun drills have been predominate over twist drills in micro drilling (i.e., drilling holes with 3mm in diameter or less) applications. Due to micro drilling's high toughness requirements, twist drills could only be manufactured from high speed steel (HSS). As a result, cutting speeds and feed rates were low, the holes had to be constantly cleared of swarf, and process reliability left much to be desired. However, special carbide grades with a high level of toughness are now available which allow the manufacture of thin, long twist drills capable of high cutting parameters.
Walter has equipped its X-treme DM line of micro drills with an array of performance enhancing features, prime among them being internal cooling.
Other features include optimized point geometry with special cutting edge preparation and flute geometry to ensure superior chip formation. These drills also feature special aluminum-titanium nitride coatings that counteract wear and increase tool life and are suitable for ISO material groups P, K, M, N, S and H. These drills can even micro drill titanium in some applications.
Walter Titex X-treme DM micro drills are designed to drill a hole in one operation without pecking, which is another factor in their superior process reliability. Features and benefits like these combine to deliver productivity increases in the 50-100 percent range.
Conditioning of the cutting edge, such as a honing or chamfering, to make it stronger and less susceptible to chipping. A chamfer is a bevel on the tool’s cutting edge; the angle is measured from the cutting face downward and generally varies from 25° to 45°. Honing is the process of rounding or blunting the cutting edge with abrasives, either manually or mechanically.
WBH20 is a grade well suited for ISO-H Group of material such as for hard turning applications. WBS10 is well suited for ISO-S materials, specifically nickel-based (such as Inconel), iron-based (such as Udimet) or cobalt-based (such as Hayens).
Available in diameter sizes ranging from 0.562-1.375 in. and 16-42 mm with 2, 3, 4 x Dc, the new drill delivers maximum process reliability with simple and efficient chip removal, two coolant channels and polished flutes. Superior protection against friction is provided by the D3120 hardened and…
The M2471 milling cutter, ideal for the aerospace and energy industries, boasts a high metal-removal rate even on low-performance machines thanks to its soft cutting geometries and positive cutting characteristics. It brings all the benefits of single-sided round inserts to double-sided round…
More cost-effective than comparable systems but just as easy on tools, the AB735 synchronous threading adaptor maximizes tool performance. In addition to the minimized wear, the modular design of the adaptor also contributes to cost-efficiency: Exchangeable front pieces for different thread sizes…
These new grades complement Walter's previously released WBH10C coated CBN and WBH10 and WBH20 CBN grade ideal for high temperature stability in hard metal turning. These inserts also have the option of chip breaker (TM-M2) for trouble shooting and wiper (MW2) for exceptional surface finish…
The MC025 Advance is available in diameters from 1/8-1 in. (1-25 mm). A single grade is offered for universal applications for steel, stainless steel, cast iron and materials with difficult cutting properties as well as its ability to lower inventory costs.The MD025 Supreme solid carbide milling…
Tangentially mounted grooving insert with a robust seating surface also ensures maximum stability. The insert and pocket design features an axial key stop for added stability against the side cutting (axial) forces. Precision cooling on the flank surface is offered as a standard feature for longer…
With the special flute geometry, the chips (swarf) are evacuated effectively. This means that hole depths of up to 12 x Dc can be easily achieved. Oil or emulsion can both be used as a coolant with these drills. For deeper holes beyond 8 x Dc, Walter has also introduced a corresponding line of…
The exceptionally smooth yet hard coating improves surface quality, which, in turn, significantly reduces torque requirements. Intended for blind hole and through hole threads and thread depths up to 3.5 x DN in steel, it has also shown good results in machining cast iron and aluminum. The TC470…
The mill is best suited to machining steel, stainless steel, cast iron, non-ferrous material and materials with difficult cutting properties. This wide range of uses results in lower tooling and administrative costs, as does the fact that its 90° approach angle dramatically decreases the need for…
