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.
Available in diameters from 1/8" to 1", the MA267/MA263 Advance tools are excellent for machining all other ISO N materials, such as copper, brass, bronze and magnesium-based alloys, in addition to aluminum. With a cylindrical shank, these tools are available with or without chip-…
When compared to competing drills, the DC180 Supreme has a tool life that is about 50% longer. An additional benefit for the DC180 drill is universal application at the highest cutting speeds. The drill is suitable for high production volume applications with a large number of holes, such as in the…
The lineup of products consists of three categories of tools. Supreme tools indicate the highest level of technology and performance available. Advance tools indicate products efficiently balanced between price and performance and Perform tools are products that provide an economical solution with…
The inserts feature three cutting edges at a 50° copying angle. Compared to the WL25 indexable inserts, which measure 25 mm per side, the WL17 inserts measure 17 mm per side. The WL25 inserts are now additionally offered in W0110-C Walter Capto tools and the W1211 QuadFit exchangeable head for…
The MA230 Advance solid carbide milling cutting is for universal machining of steel, stainless steel, cast iron and high-temperature superalloys (ISO P, M, K and S workpiece groups) at the highest level. The MA230 Advance cutter is for high-performance roughing and finishing and enables reliable…
The primary applications for the DC183 Supreme solid carbide drill are machining steel, cast iron and non-ferrous materials (ISO P, K and N). The secondary applications are super alloys and stainless-steel materials (ISO S and M). The main targeted areas of use are automotive, aviation and energy…
The WKK25G grade is a true specialist when milling today’s cast irons (ISO K material group), such as ductile cast iron. Specifically, the grade is ideal for unfavorable milling conditions, such as interrupted cuts, and for wet machining applications. The grade meets the most stringent requirements…
Ideal for holemaking without a pilot drill up to 10×Dc, the inserts provide time savings that boost productivity. The inserts were designed to achieve maximum tool life in stable machining conditions thanks to the wear resistant WPP25 grade with HIPIMS technology. The grade has a particularly hard…
The new grade is Walter’s response to the upwards trend towards milling steel with difficult machining properties and wear-resistant stainless steel, such as found in applications in the energy and aviation industries. WSM35G meets the most stringent requirement for process reliability, which is…
The curved wiper cutting edge is a unique feature that makes the wiper action universal across various material groups such as steels, stainless steels, cast irons or even super alloys. The wiper action can be used to reduce machining time by using double the feed rate, while imparting the same…
