Milling Cutters

The addition to the "TPW / EPW Type" series includes CBN inserts designed for high-speed cast iron finishing. In addition to the economical 2-corner standard insert, a wiper insert option is also available to achieve excellent surface finish. The insert grade is High-content CBN "BX480," which consists of densely bonded medium-grain CBN. This grade offers high hardness, toughness, and superior thermal conductivity, making it suitable for high-speed machining at cutting speeds (Vc) exceeding 1000m/min.

Walter expanded the TC630 Supreme product range to include UNJC4 to UNJC9/16, UNJF4 to UNJF9/16 and MJ3 to MJ10 thread sizes. Optional internal coolant is available for thread sizes starting from MJ4, UNJF8 and UNJC8 to provide effective chip removal on deep threads.

The M5250 cutter is effective for milling steel, cast iron, stainless steel, aluminum and other non-ferrous metals (ISO P, K, M and N workpiece groups), as well as materials with difficult cutting properties. Unlike other full-effective helical milling cutters, the XTRA∙TEC® XT M5250 can also be used for full slotting, shoulder milling, pocket milling and ramping. The positive rhombic basic shape of the face insert makes ramping possible.

The TC685 Supreme cutter is a left-hand cutting tool that features a 15° helix angle for excellent chip removal. Cooling with compressed air makes it possible to achieve maximum tool life in materials harder than 50 HRC. Additionally, internal coolant delivery is available for tools that create the M6 size through the larger thread sizes. The tool shank is in accordance with the DIN 6535 HA standard.

The larger diameter cutter and new lengths both boost the Fullcut Mill FCM BBT line’s already-considerable versatility, allowing machinists to tailor their tool selections for many different applications. The BIG-PLUS BBT shank products are compatible with both BIG-PLUS and existing BT spindle machines. This allows for seamless integration, no matter the machining setup.

The advanced design combines a strong insert structure, a durable cutter body, secure mounting, and advanced carbide grades. This innovative solution enables face and square shoulder milling, while providing an additional option for milling close to shoulders where there are workpiece or work holding fixture constraints. 

The XNMU inserts are the original concept of double-sided inserts with 4 right-hand and 4 left-hand helical cutting edges for slot milling cutters. These inserts are made of SUMOTEC carbide grades, designed for milling alloy steel, ferritic and martensitic stainless steel, and cast-iron. 

When mounted in a NEOFEED tool, the insert enables a positive tool rake angle which assures smooth cutting and reduced cutting forces and power consumption. The insert pocket has a dovetail shape that provides rigid and reliable insert clamping and improves the a cutter’s capability to withstand heavy load. These features provide increased cutting data for better productivity and for improved tool life.

The milling heads have been designed for shoulder roughing, semi-finishing and finishing applications with ramping down capability. The milling heads are available in .312-1.00” diameter range.

The spline connection designation is SP… where the no. indicates the connection size.
The general duty cutting geometry of the heads is suited for efficient slot milling on a wide spectrum of workpiece materials for maximum depth of cut.
