Walter has introduced single-sided indexable inserts with new HU5 geometry. These HU5 inserts can dramatically boost productivity particularly in rough machining of stainless steels and heat-resistant superalloys and secondarily in steel. They are typically used in machining AISI 316 material, Inconel 718 and titanium.
The main cutting edge, which is protected by a negative chamfer, prevents insert fractures when machining hard scales and heat affected zones and thus optimizes insert performance in forged parts. Components with interrupted cuts and other demanding machining operations benefit as well.
Compared to double-sided negative inserts, HU5 has a large seating surface. This increases stability and permits greater cutting depths, feed rates, and metal-removal rates. In addition to the stable seating, the key factor in this improved productivity is the combination of HU5 geometry and Walter’s Tiger·tec Silver grades. This combination leads to increased tool life up to 75%.
With HU5 geometry, the curved cutting edge and deep chip groove produce low cutting forces even at high feed rates, reducing heat buildup. The variable rake angle at the corner radius allows for lower cutting forces and increases tool life. Available in grades WPP10S, WPP20S, WMP20S, WSM20S and WSM30S, the HU5 geometry rounds out the extensive Walter product range in the areas ISO S and M, leading to a total of 12 insert shapes in six grades.
Angle of inclination between the face of the cutting tool and the workpiece. If the face of the tool lies in a plane through the axis of the workpiece, the tool is said to have a neutral, or zero, rake. If the inclination of the tool face makes the cutting edge more acute than when the rake angle is zero, the rake is positive. If the inclination of the tool face makes the cutting edge less acute or more blunt than when the rake angle is zero, the rake is negative.
Stainless steels possess high strength, heat resistance, excellent workability and erosion resistance. Four general classes have been developed to cover a range of mechanical and physical properties for particular applications. The four classes are: the austenitic types of the chromium-nickel-manganese 200 series and the chromium-nickel 300 series; the martensitic types of the chromium, hardenable 400 series; the chromium, nonhardenable 400-series ferritic types; and the precipitation-hardening type of chromium-nickel alloys with additional elements that are hardenable by solution treating and aging.
The PCD inserts impart the finest surface finishes while shoulder, face and slot milling. The tools enable precise machining with reduced cutting forces and minimal vibration tendencies. They have a low cost because of their extremely long tool life as a result of the cutting edge being made of the…
WBH20C WL25 indexable inserts are full-radius copy turning inserts with Walter Lock positive engagement. The WL positive engagement provides maximum stability and precision for reliable machining of contours. With pocket support right under the cutting edge, and exceptional ability to prevent…
The MD344 Supreme and the MD340 Supreme three-flute versions both feature a 38° helix, while the MD340 Supreme four-flute has a 39°/41° variable helix, the MD340 five-flute version features a differential or unequal pitch.
A new type of flute design reliably evacuates chips, even with the tinniest drills. This capability ensures that hole depths up to 30 × Dc can be easily achieved with the DB133 Supreme micro drill with its 140° point angle. The DB131 Supreme micro pilot drill features a 150° point angle. Emulsion,…
To cover the widest possible range of applications, Walter offers the MP6 geometry in CCMT, DCMT, TCMT and VBMT basic shapes. Its short protective chamfer, which is characteristic of roughing inserts, ensures a high strength of cutting edge, even in challenging conditions, for example when…
TC388 Supreme (50–58 RC) and TC389 Supreme (55–65 RC) feature new patent-pending cutting geometries that fully shear off the root of the chip when reversing, thus torque peaks are minimized. This prevents fractures, prolongs the tool life, and increases process reliability. Furthermore, the new…
The 180°-point angle makes the DC118 Supreme ideal for plunging into inclined or round surfaces because the drill is guided quickly on the margins and centered accurately. At the same time, burr formation remains extremely low. The protective corner chamfer on the cutting edges protects against…
These WXN15 grade coated inserts are all introduced with a highly positive shaped geometry, which is particularly effective in machining ISO N materials. When used in advanced cutter bodies like the new Xtra·tec® XT M5468 button insert milling cutter, with G88 geometry, this also increases…
The system handles axial grooves from dia. 2.362-in (60 mm), cutting depths up to 1.299-in (33 mm), with insert width of 0.197-in (5 mm). The new system delivers maximum productivity and cutting parameters due to optimal cooling, strength and controlled chip breaking, along with high cost-…
The TC620 Supreme thread milling cutters utilize patent-pending Walter DeVibe technology with an anti-vibration land to effectively suppress vibrations and allow higher cutting parameters, while contributing to other TC620 Supreme advantages like a high level of process reliability and easy…
