NOT A MINOR DETAIL – MAJOR STABILITY
Walter introduces the new WL17 indexable inserts
Tool specialist Walter is expanding its WL copy turning system with the introduction of the new WL17 indexable inserts for Swiss type auto lathes and small Dmin. Used on the W1011-S-P external turning toolholder, which is also new and the W1210/W1211 boring bars, they bring the benefits of the existing WL25 inserts to smaller dimensions. The W1011-S-P toolholders with square shank in the most common shank sizes, 12×12 mm and 16×16 mm are specially designed for use on automatic lathes and multi-spindle machines. Walter is the only manufacturer to offer a turning system for automatic lathes with positive engagement and three-edge turning inserts. As with the WL25 turning inserts and toolholders, the smaller indexable inserts facilitate equally high cost-efficiency. This is partly thanks to the three cutting edges, as well as stability and higher indexing accuracy (+50 percent compared with ISO inserts). The targeted Walter precision cooling on the rake and flank faces also increases tool edge life.
When it comes to internal turning, the inner diameter (Dmin) of the workpiece is often a limiting factor. ISO turning inserts, such as the VBMT11, have only two cutting edges and can be used at a 93° approach angle from a Dmin of 22 mm. By contrast, the new Walter boring bars W1210 and W1211 with WL17 inserts can be used for internal turning from Dmin 18 mm and have one more cutting edge. Plus, the operator can use the indexable inserts for both forward and reverse turning. Just like all WL inserts, the WL17 inserts can be used in a neutral, right-hand and left-hand version and are coated in the latest cutting tool materials, such as Tiger·tec® Gold. Thanks to its high stability and cost-efficiency, the WL17 copy turning system is ideal for internal turning of small diameters and for use on automatic lathes.

DRILLING ALUMINIUM WITHOUT ADHESIONS
Walter presents the DC166 Supreme with innovative new thinner web
In the field of aluminium machining, operators often look for more specialist tools since their requirements are often very specific. But with their new DC166 Supreme, premium tool manufacturers Walter have demonstrated just how special a standard drill can be. The solid carbide drill with internal coolant has been specially developed for machining aluminium and other ISO N materials, which is why it boasts certain distinctive features, including all key surfaces on the drill, such as flutes, lands or clearance angles are polished. This reduces friction and prevents adhesions in the highly adhesive material, which in turn increases tool life and process reliability of the drill. The highly innovative, patent-pending thinner web of the DC166 Supreme is like nothing else on the market. It prevents edge from building up and improves chip removal and supply of cooling lubricant.
The aluminium specialists’ innovative design facilitates exceptionally high cutting speeds in conjunction with excellent drilling quality – especially in terms of the roundness of the hole and surface quality. Walter is launching the DC166 Supreme, which can be used with emulsion, oil or minimum quantity lubrication (MMS), in 5 × D, with a diameter of 3–12 mm. By having it available as standard, the company is able to quickly show the drill’s performance in action to potential users. At the same time, however, Walter also offers the drill as a special tool (up to 30 × D; dia. 3–20 mm) via the Walter Xpress Service with a shorter delivery time of maximum two weeks. The DC166 Supreme is of interest for all areas of application dealing with ISO N materials, especially the automotive sector and supply industry and aircraft construction.
