Emuge

MultiTap is the first high performance tap designed to cut a wide range of materials including carbon steel, steel alloys, stainless steel, aluminum, cast iron, copper, brass, and bronze, according to its developer, Emuge. The new tap is designed to produce threads within both 2B and 3B classes of fit, eliminating the guesswork of calculating H-limits.

“MultiTap is the ideal tap for a job shop or a manufacturer who works with short and medium run threading applications across a wide spectrum of materials. It will significantly improve thread quality and boost output while reducing production costs, because one high performance MultiTap will handle most common materials and applications. MultiTap eliminates the need to stock numerous types of taps in the tool crib,” says Peter Matysiak, president of Emuge Corp.

The tap is constructed of a proprietary grade of high speed steel (HSS-E), Nitrided with a Ne2 surface treatment. It is available in both spiral point and spiral flute configurations for through-or blind-hole applications. Tap sizes cover a full range for UNC or UNF threads, from #4-40 to ¾ in.-16 in. sizes, to metric sizes from M4 x 0.7 to M16 x 2.0.

The company says it is also offering guaranteed performance. If the tool does not successfully outperform the user’s current taps in most common materials, the tool purchase will be fully refunded.

Iscar

Iscar’s SumoCham drills are the next generation of the company’s ChamDrill and CamDrillJet, featuring improved head and pocket designs, no setup time, fast metal removal and economical indexing. The line incorporates a clamping mechanism for improved productivity output rates while enabling more insert indexes. The shank is designed with twisted nozzles and features a constructed body that is durable and stable. The indexable heads are available in four different geometries and each is designed for drilling steel, exotic materials, cast iron or aluminum. Diameter ranges are 7 to 25.9 mm with a drill ratio of 1.5, 3.5, 8 and 12 x.

The pocket design takes advantage of the cutting forces, mechanically exerted upon the tool. These forces are then converted into gripping forces that are used for tightening the insert towards the back of the pocket. In that sense, the more cutting forces applied, the better gripping forces obtained. The clamping forces around the connection area generate less strain, preventing any potential plastic deformation and enabling at least triple the amount of head indexes.

The most important attributes are a 50 per cent increase in productivity, low clamping torque, and reduced internal stress in the pockets, which increases tool life.

The drill head is also designed with a cylindrical connection, eliminating any possibility of insert pull-out, while utilizing an enlarged clamping area and stopper at the back.

In one application for a manufacturer of heat exchanger products, the drilling operation required 1700 holes per part, made out of SAE carbon steel. Iscar recommended a 25 mm SumoChamDrill, which provided a 30 per cent increase in cutting speed and a 25 per cent increase in feed rate compared to previous tooling on the machine. The table feed was also increased by 33 per cent and the indexing time took only 10 per cent of the time it had in the past. The drilling time per part was consequently reduced by 40 per cent while productivity increased by 63 per cent. This combination led to a total cost reduction of 21.4 per cent.

Komet

The replaceable head system of the two-edged Komet Kub K2 combines flexibility with maximum performance. According to the company, it has demonstrated through other production introductions that modularity brings you cost efficiency and flexibility in a wide range of tooling systems ranging from continuous drilling and boring to reaming. However, with applications requiring smaller hole diameters, the more challenging it becomes to make it possible to use replaceable cutting edges in the form of indexable inserts or changeable heads.

The K2 is based on basic holders with a parallel shank, where double-edged carbide changeable heads have been adapted. This is done using a patented self-fixing and self-centering attachment point. The process of changing the cutting head becomes extremely easy, even in the machine. The replaceable head system makes it possible to use a wide selection of high-end geometries. The optimized surface finish quality of the cutting channels ensures excellent chip removal while the basic bodies achieve an extremely high performance level and tool life thanks to a special surface finish quality.

Two basic body variants are available: 3 xD and in 5 xD as well as changeable heads in two coating variants “8425“ and “2725“ for machining steel, cast iron, aluminum and stainless materials. The available diameter ranges of 12 to 15.9 mm are covered in increments of 0.01 mm. Additional diameters from 8 up to 18 mm will be available soon.

Widia

In deep hole drilling applications up to 30 times in diameter, new solid carbide Widia-Rubig drills remove between three and four times the metal compared to gun drills, in addition to delivering excellent hole quality and cycle times.

“Three or fourfold increases in metal removal rates mean significant improvements in a customer’s bottom line, whether it be in increased throughput, additional capacity for drilling equipment, or better-utilized personnel,” says Chris Merlin, senior global product manager, holemaking.

Length ratios for the new deep hole drills are available in diameters of 15 x, 20 x, 25 x, and 30 x. Available diameters range from 3.0 to 13.0 mm.

Along with increased performance, the solid carbide deep hole drills increase process versatility by not requiring special drivers or guide bushings. And where gun drilling machines are dedicated to gun drilling only, the Widia-Rubig deep hole drills can be used in machining centres, eliminating the need for specialty capital equipment.

With 132° cone-point geometry, the drills have low thrust and excellent centering ability for increased hole quality. A four-margin design improves stability in the cut and an advanced PVD coating and highly polished surfaces increase wear resistance and reduce friction on margins and cutting edges.

“Higher tool life and feed rates are considerable advantages with these tools, and adding that customers will be drilling more holes per drill and getting longer life and more regrinds per drill seals the deal,” adds Merlin.
