Our corner radius end mill range combines solid carbide substrates, advanced multi‑axis grinding, and rigorous metrology. The result is strong cutting edges, consistent radii, and clean finishes in steels, stainless, hardened materials, cast iron, aluminum, titanium, nickel alloys, and composites. Tools are built in our modern Changzhou facility on Swiss TTB, WALTER HELITRONIC, DECKEL, and ANCA platforms. Each tool is engineered for stable slotting, profiling, ramping, and 3D contouring with sub‑micron precision and ISO9001/SGS‑backed quality.
The corner radius reinforces the cutting edge versus a square profile, reducing micro‑chipping in interrupted cuts and heavy side loads. Optimized rake and relief geometries distribute stress through the fillet, enabling higher feeds and extended life in continuous production—ideal when a bull nose end mill profile is preferred.
Precision‑ground radii and controlled runout minimize cusp height on fillets and 3D surfaces. Tight radius tolerance, vibration damping, and fine‑edge preparation support mirror‑level finishes on die/mold cavities and aerospace components with fewer secondary steps.
Application‑specific geometries and coatings are matched to your workpiece: AlTiN/TiAlN/TiSiN for alloy and hardened steels, ZrN/DLC for aluminum and non‑ferrous, and diamond for abrasive composites and graphite. One platform covers roughing to semi‑finishing across diverse materials.
Rigid cores, variable helix/variable pitch options, and high‑precision shanks reduce chatter and heat, helping maintain dimensions over long cycles. Automated grinding and 100% critical‑feature inspection deliver repeatable carbide tooling and batch‑to‑batch consistency.
Choose 2–6 flutes and specialized flute forms to balance chip evacuation and surface quality. Variable helix, corner protection chamfers, and chip splitters are available. Select features to tailor performance for slotting, profiling, or high‑speed finishing, including 4‑flute radius end mills.
Select small to large radii to match design fillets, extend edge life, or strengthen the tool for heavy side milling. Precision grinding ensures consistent radius size and a smooth blend for accurate part geometry and predictable wear—ideal for fillet machining.
Micro‑grain and ultra‑fine carbide grades provide toughness and wear resistance. Coatings include AlTiN/TiAlN/TiSiN for heat resistance, ZrN/DLC for aluminum to prevent built‑up edge, and diamond for abrasive non‑metals.
High‑precision shanks pair with our collet chuck systems to minimize runout and vibration. This improves dimensional accuracy, finish, and tool life at elevated cutting speeds with any corner radius model.
We design and manufacture custom tools from drawings or samples. Options include special diameters, radius sizes, flute counts, helix/lead angles, step designs, neck relief, extended reach, and unique shanks to solve tight‑tolerance features.
Each tool is engineered to your material and process, including machine power, toolholding, and coolant strategy. Optimized geometry and coatings improve stability, reduce cycle time, and lower total tooling cost through machining refinement.
Rapid prototyping on advanced grinding centers and comprehensive metrology enables quick iteration of a prototype radius end mill. Proven designs are scaled with automation for consistent large‑batch delivery and repeatable performance.
Ideal for die and mold milling, aerospace machining, medical, and general engineering where fillets and blended surfaces are required. Suited to carbon/alloy steels, stainless, tool steels, cast iron, aluminum, titanium, nickel alloys, and composites.
Use for profiling, slotting, ramping, pocketing, and semi‑finishing/finishing of 2D/3D forms. Corner radii minimize notch wear in high‑speed and trochoidal milling, enabling aggressive parameters without edge breakage.
Swiss TTB micro grinding, WALTER HELITRONIC, DECKEL, and ANCA provide sub‑micron capability, thermal stability, and multi‑axis control for consistent geometry and edge integrity.
ZOLLER presetting and PARLEC/PG1000 systems verify cutting diameters, corner radii, runout, and edge quality. Results are traceable and repeatable to support tight‑tolerance applications.
ISO9001 (2023–2026) and SGS‑backed processes ensure consistent quality from raw materials to final inspection for continuous production needs.
Balanced core designs, precision grinding, and fine‑edge preparation deliver strong radius fidelity and clean surface finish. Expect reduced burrs, minimized tool marks on fillets, and stable performance at elevated parameters—even in difficult materials.
Select it when edge strength and finish on filleted features matter—slotting with side loads, machining pockets with corners, and blending 3D surfaces.
Match the tool radius to the part fillet for accuracy. If durability is critical, choose a slightly larger radius to increase edge strength without compromising geometry.
Use ZrN or DLC for aluminum/non‑ferrous to prevent built‑up edge; AlTiN/TiSiN for steels and hardened steels to resist heat and abrasion.
Yes. We reverse‑engineer from samples or drawings, replicate or improve geometry, and validate with metrology for consistent production results.
Square, ball, and aluminum‑specific geometries extend capability from roughing to finishing.
Combine precision holes with clean edge blending and contour finishing.
Tungsten steel taps maintain thread quality after milling.
Minimize runout and vibration to enhance accuracy and tool life.
We align geometry with material and process, backed by sub‑micron grinding and full inspection on corner radii. Tailor‑made designs help shorten cycle times, improve finish, and extend edge life—especially in tough alloys and long runs. Contact us to discuss your application or request a quote.
