Iwaki City, Fukushima Prefecture – June 2026 – Tungaloy Corporation (President & CEO: Satoshi Kinoshita, Headquarters: Iwaki City, Fukushima Prefecture) announces a significant expansion of the cutter body lineup for its TungForce-Rec series of high-efficiency, high-precision square shoulder milling cutters. New cutter body options have been added in the 06, 12, and 18 insert sizes.
Challenges and Trends
In machining operations for automotive components, dies and molds, industrial machinery, aerospace, energy, and other industries, parts are becoming smaller and more complex. As a result, a wider variety of tools is required.
In many applications, users need cutter diameters that can prevent shank interference even with a long overhang. They also need cutter bodies with different overhang lengths, even when the cutter diameter is the same. For this reason, there is a strong demand for a cutter series that can deliver stable performance in many different machining applications.
Product Overview
The TungForce-Rec series is a square shoulder milling cutter line designed for high-efficiency and high-precision machining. It uses uniquely shaped two-corner inserts and is available in four insert sizes: 04, 06, 12, and 18. The series covers maximum depths of cut from 4 to 16.5 mm. In combination with cutter body diameters from ø6 to ø160 mm, it can support a wide range of machining applications.
All insert sizes use Tungaloy’s original V-bottom insert design. This design stabilizes insert behavior during machining and provides high insert clamping rigidity. As a result, TungForce-Rec enables stable, high-efficiency machining even in small-diameter applications around ø10 mm. The series delivers excellent machining accuracy and productivity not only in shoulder milling, but also in slotting, pocketing, and many other milling operations.
With this expansion, Tungaloy adds a wide range of cutter body variations in the 06, 12, and 18 sizes. These additions allow users in more industries and applications to select the optimal tool and achieve high-efficiency machining.
Benefits and Features
Feature 1: High-rigidity clamping and a diverse tooling lineup support a wide range of square shoulder milling applications.
– Four insert sizes — 04, 06, 12, and 18 — cover maximum depths of cut from 4 to 16.5 mm.
– The cutter body lineup includes shank-type, bore-type, and modular-head options. In combination with the TungFlex holder series, users can select tooling with the optimal overhang length for each machining application.
– The insert is securely clamped to the cutter body with a single screw by using Tungaloy’s original V-bottom insert design. This provides high cutting-edge rigidity.
Feature 2: Significant expansion of cutter body variations in 06, 12, and 18 sizes
– 06 size:
New ø22 mm and ø28 mm cutter diameters have been added to the EPAV06 shank-type cutter lineup. With these cutter diameters, the cutting edge is positioned outside the shank diameter of ø20 mm or ø25 mm. This helps prevent interference between the shank and the workpiece, even when machining with a long overhang.
– 12 size:
The EPAV12 shank-type cutter lineup has been expanded with additional body length and tooth-count options in cutter diameters from ø18 to ø50 mm. In addition, the TPAV12 bore-type cutter lineup has been expanded with additional tooth-count options in cutter diameters from ø40 to ø100 mm.
– 18 size:
New ø28 mm and ø35 mm cutter diameters have been added to the EPAV18 shank-type cutter lineup. Since the cutting edge is positioned outside the shank diameter of ø25 mm or ø32 mm, interference between the shank and the workpiece can be avoided even with a long overhang. In addition, the new HPAV18 modular-head cutter has been added in ø25, ø32, and ø40 mm diameters. In combination with the TungFlex series, users can select tooling with the optimal tool length.
