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.
Walter has introduced the DB130 Advance, its smallest solid-carbide microdrill with diameters from 0.004 to 0.06 in. (0.1 mm to 1.45 mm). With a point angle of 118° and cylindrical shank, the drill meets DIN 1899 standards.
Walter has announced several extensions to its Tiger-tec Gold inserts, all of which possess the features that have made it so successful: A smooth rake face for excellent friction characteristics; optimal wear detection due to its gold-colored top layer; an especially tough cutting edge for maximum…
The new WCK10 ceramic cutting grade from Walter is optimized for roughing gray cast iron at high cutting speeds, with either continuous or interrupted cutting. The inserts deliver improved productivity, process reliability and longer tool life due to their new Si3N4 wear-resistant ceramic cutting…
Walter has introduced its ISO H Advance Line of solid-carbide milling cutters, consisting of seven new cutter families specially tailored to the requirements of hard machining (up to 63 HRC). These new cutters include mini and multi-flute, shoulder/slot, ball-nose and high-feed milling cutters,…
Walter has introduced two new insert grades in its Perform Line of turning tools, the WPV10 and WPV20. These versatile, cost-effective inserts are suitable for users whose machines are limited in cutting parameters due to their stability and performance, and who need a versatile insert that can…
Walter has introduced the TC120, TC121 and TC122 Supreme, three new blind-hole taps that combine maximum performance in steel with improved tool life and process reliability. These new entries in the Walter Supreme line have been specially developed for machining steel.
Walter has expanded the range of its innovative T2711/T2712 thread milling cutter family for cutting large threads with two new tool bodies for the M56 and M64 threads and three new thread milling cutter inserts. Walter's multiple-row T2711/T2712 thread milling cutter family, which can…
Walter has expanded its popular Paradur HT HSS-E blind-hole tap range by adding UNC thread dimensions. Previously available in dimensions M4-M36 and M10×1-M33×2, Walter has now expanded the range of the taps to include dimensions UNC 1/4-UNC 1.
The new Walter Cut MX grooving and parting tool reportedly improves accuracy, stability and process reliability by adopting and improving on proven technology. These new indexable inserts have four cutting edges per insert.
The new MD133 Supreme milling cutter from Walter, designed specifically for dynamic milling, delivers increased process reliability, particularly during unmanned operation. It reportedly boosts productivity thanks to a higher metal-removal rate and a reduction in machining time.
