Technical notes
- The KERNVEX TEX corner radius end mill is a solid carbide milling cutter designed for stainless steel roughing, semi-finishing, shoulder milling, and profile machining. Its reinforced corner radius helps distribute cutting loads and reduce the risk of corner chipping. The tool features Balzers AP AlCrN coating, a 45° helix angle, an 8° rake angle, 88°/92° unequal flute spacing, and dual-core geometry (52%/70%) to support cutting stability and wear resistance.
- The TEX Series is suitable for stainless steels such as 304 and 316 and can also be used for nickel-based alloy machining under appropriate cutting conditions. The corner radius should be selected according to the required part geometry, cutting load, and machining stage.
- Corner Radius Standard Size for Stainless Steel Machining
- Our TEX Series corner radius end mills are available from 1.0 mm to 12 mm in diameter, with corner radius options from R0.2 to R3.0. They offer strong versatility for everything from precise pocket features to high-load semi-finishing in stainless steel machining.
- Corner Radius End Mill Applications
- TEX corner radius end mills are suitable for stainless steel milling operations where cutting-edge strength and profile stability are important. Compared with a sharp-cornered square end mill, the reinforced radius helps distribute cutting loads and reduce stress concentration at the tool corner.
- How to Choose the Corner Radius
- The TEX corner radius end mill range includes diameters from 1.0 mm to 12 mm and radius options from R0.2 to R3.0, depending on the tool specification.
- Small corner radius: Suitable for detailed profiles, smaller corner transitions, and applications requiring limited corner rounding.
- Larger corner radius: Provides greater corner support for suitable roughing and semi-finishing operations, provided the radius is compatible with the part geometry.
- The selected radius should match the workpiece corner requirements and machining allowance. A larger radius is not automatically better for every application.
- Nickel-Based Alloy Machining
- In addition to stainless steel, KERNVEX TEX Series corner radius end mills can be considered for nickel-based alloy machining. Nickel alloys often present challenges including high cutting resistance, work hardening, and concentrated cutting heat.
- The reinforced corner radius, Balzers AP AlCrN coating, and optimized flute geometry are designed to support cutting-edge stability and wear resistance. However, the recommended tool size, corner radius, and cutting parameters must be selected according to the alloy grade and machining conditions.
- For nickel-based alloys such as Inconel, please contact KERNVEX with the exact material grade, machining operation, and required tool dimensions for application-specific recommendations.
- TEX Square vs Corner Radius vs Ball Nose End Mills
- KERNVEX TEX Series carbide end mills are designed for stainless steel machining and can also be used for nickel-based alloys under suitable cutting conditions. Square, corner radius, and ball nose end mills serve different machining purposes. The right cutter depends on the workpiece geometry, machining stage, and required surface finish.
- Selection Tip: Choose a square end mill for flat surfaces and defined corners, a corner radius end mill when stronger corner support is required, and a ball nose end mill for curved surfaces and complex 3D finishing. Actual performance depends on tool specifications, material grade, and machining conditions.
