2-Flute Corner Radius End Mill
Reading the size options — R (corner radius) × shank Ø × flute length × overall length, all in mm. Example: 1R0.2×D4×3×50 = 1 mm cutting diameter with R0.2 corner, 4 mm shank, 3 mm flute, 50 mm overall.
Recommended workpiece materials — BK2055
Stainless steel, carbon steel and alloy steel up to HRC 45. A general-purpose carbide grade built for everyday milling, drilling and tapping where toughness and edge stability matter more than hot hardness.
Milling stainless steel — three grades to choose from
- BK2055 — general-purpose carbide for stainless and steel up to HRC 45. Best value when one tool has to cover mixed work.
- SUS Series — 4-flute corner-radius geometry developed for stainless, titanium and heat-resistant alloys.
- JIN — TiZr coating with a 38°/40° unequal helix, for side milling and dynamic paths where chatter is the limiting factor.
Alloy Coating on Cutting Edge
TiSiN Coating
Coated Cutting Edge
Cutting edge coated with Balzers coating enables direct rough - to - finish machining of materials, reduces tool changes, improves machine utilization, and saves production time.
for Stainless Steel/Die Steel/Cast Iron/Tool Steel/ Metal Copper/Iron Plate ect.
Ultra - Fine Particle Cemented Carbide Base Material
Adopting ultra - fine particle Cemented Carbide base material, it has high wear resistance and strength, and is a milling cutter for high - hardness high - speed cutting applications.
Two - Flute, Mainly for Side Milling and Keyway Machining
Large Chip - Evacuation Flute
Fully Ground Flute
Smooth Chip Evacuation
Sharp and durable wide spiral flute for smooth chip evacuation
Facilitates high - speed machining and improves overall machining efficiency
Sharp Rake Angle for Rapid Cutting
Innovative improved process greatly enhances the sharpness of large rake angle, reduces cutting heat generation, and solves the tool sticking problem at the source.
General Purpose Chamfering Round Shank
component designed for chamfering applications with a round shank that offers good compatibility, ease of use, secure clamping without slipping, and enhanced milling cutter vibration resistance and cutting speed.
