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.
The MP060 face milling cutter with a great number of teeth (z) between 10 and 22, and with diameters from 40 mm, can be used for roughing and finishing large surfaces and flat shoulders. The MP160 (z = 3–4) and MP260 (z = 2–3) shoulder and slot milling cutters, with either cylindrical shank or…
In addition to the cooling and geometry, Walter's new WJ30RZ and WJ30RY grades also boost performance because their highly wear-resistant TiAlSiN-based layer applied using HIPIMS coating technology takes the form of a complete coating for 3 and 5xDc (WJ30RZ grade) and a point coating for 8×Dc…
The primary application of the Tiger·tec Gold inserts is steels with various tensile strengths that can be machined. These indexable inserts are ideal for use in the automotive, energy, and general metalworking industries, where the inserts can significantly help reduce the cost per component.…
Additional improvement in surface quality and stability can be realized with advanced wiper geometry option. Walter offers the new WBH30 CBN grade in inserts with and without MW wiper geometry, and with a negative T-land chamfer for excellent strength in interrupted cuts.
This milling cutter can be used universally for steel, stainless steels, cast iron and difficult-to-machine materials, in face, shoulder, ramping, pocket, and circular interpolation milling operations. Available in diameters of 32-100 mm, a maximum depth of cut of 5 or 8 mm), with Weldon shank or…
There are two indexable insert sizes with facet—SDMX0904ZDR-E27 and SDMX1205ZDR-E27. The M4002 cutter provides a depth of cut of 1.5 or 2.0 mm and is available in diameters of 25-125 mm or 1-4 in. and is ideal for high-speed milling in steel and cast iron, stainless steel and materials with…
The standard A2201 is an offset adaptor for reduced radial forces, greater stability and provides more space between the boring bar and the bore wall for improved chip removal with very deep bores. With the A3001 and the A2201 Walter has increased boring bar diameters to 2.5-4-in. and 60-100 mm.
The Xtra·tec XT M5009 face milling cutter has a 45° approach angle, is available in diameters of 25-160 mm (1-6 in.) and provides a depth of cut of 5 or 6.5 mm. It features three pitches for different applications (tools with wide and medium pitch for insert size SN X1205 are designed with carbide…
Positive with four cutting edges, it can be used on both sides, thus combining long tool life and high metal removal rates with greater cost-efficiency. The polished rake face improves chip removal, and the extremely sharp cutting edge creates a softer cutting action, important factors in the…
The M5004 octagon milling cutter combines efficiency and process reliability while also extending tool life, resulting in maximum productivity. Process reliability is enhanced thanks to the new tool's high stability. Lower tool costs and reduced time and labor result from its universal…
