This 55HRC 3 flute chamfer end mill is designed as a robust 90 degree chamfer end mill for efficient edge breaking and deburring on medium-hard steels. The optimized 3-flute geometry offers stable cutting, smoother chip evacuation and a clean surface finish when machining holes, pockets and profiles. Manufactured as a carbide chamfer end mill with precise grinding, it provides long tool life and reliable performance in continuous production. Ideal for both CNC and conventional setups, this chamfer end mill cutter helps you achieve consistent chamfers and reduce secondary finishing operations.
Grade HN40 is made from submicron WC powder, some speclal additlves added to optimize theproperties with good combination of hardness and toughness.
Its suitable for making drills and miling tools for machining stainless steel, tool steel and heat-resistingalloys.

| TiSiN | Ti (titanium): main element, forms TiN nanocrystalline phase. Si (silicon): usually 6–10%, forms amorphous Si₃N₄ phase, refines grains and increases hardness. N (nitrogen): combines with Ti and Si to form a composite structure. | Colour: TiSiN coatings usually appear bronze or dark grey-bronze; exact colour depends on Si content, deposition process (such as PVD) and thickness (1–4 μm). Hardness: 34–42 GPa (≈3400–4200 HV). Friction coefficient: 0.3–0.6 (against steel). Temperature resistance: 1000–1200°C (oxidation resistance). Coating thickness: 1–5 μm (typically 2–3 μm). Deposition temperature: 200–400°C (suitable for carbide tools). | Ultra-high hardness: amorphous Si₃N₄ phase suppresses dislocation movement, giving much higher hardness than TiN (~23 GPa) and TiAlN (~35 GPa). High-temperature stability: suitable for dry cutting and high-speed machining (e.g. quenched steels HRC 60+). Anti-adhesion: reduces built-up edge when machining aluminium alloys, stainless steels and other sticky materials. | Tool coatings: drills, mills (especially suitable for PCB routers, tool life increased by 2–3 times). High-speed cutting of quenched steels, titanium alloys and high-nickel alloys. Mould strengthening: die-casting moulds and stamping dies, improving wear resistance. Industrial parts: piston rings and other high-temperature wear parts. |
A chamfer end mill is a milling tool used to create a beveled edge around holes, profiles and part outlines. Unlike a flat end mill, a chamfer end mill cutter is optimized for edge breaking, deburring and countersinking, giving a clean, consistent end mill chamfer in one pass.
HNCarbide offers multiple chamfer end mill cutting angle options, including 45 degree chamfer end mill, 60 degree chamfer end mill and 90 degree chamfer end mill designs, as well as special angles on request. You can simply match the tool angle to the chamfer specified on your drawing.
A carbide chamfer end mill delivers higher hardness, heat resistance and wear resistance than HSS tools. This allows higher cutting speeds, longer tool life and better surface finish when chamfering steel, stainless steel, cast iron and abrasive materials. materials.
Yes, many users run the same chamfer end mill on steel, stainless steel and aluminum for general edge breaking. For best performance, choose a versatile carbide chamfer end mill grade and coating, and adjust cutting data according to each material.
Yes. We can produce non-standard tools according to your drawings, samples or machining requirements (material, coating, size, tolerance and application). Our engineers will evaluate and provide a quotation and lead time.
For serious buyers and distributors, we can offer free standard samples if in stock. Usually you only need to cover the freight cost. For customized tools, a sample fee may apply, which can be refunded or deducted in bulk orders.

HNCarbide chamfer end mill tools are designed to handle everything from light deburring to heavy-duty edge preparation in a single, reliable operation. Whether you need to break a sharp edge on a 3D profile, clean up the rim of a drilled hole or prepare sealing and assembly faces, our chamfer end mills help you create a precise and repeatable end mill chamfer without extra setups. Popular options such as the 45 degree chamfer end mill and 90 degree chamfer end mill cover most everyday jobs, while specialized back chamfer end mill designs allow you to machine chamfers from the reverse side of the workpiece for complex parts and deep features.
From automotive and mold making to aerospace and general engineering, shops use HNCarbide corner chamfer end mills to reduce manual deburring, improve part consistency and protect critical edges from chipping. By integrating chamfering directly into your milling cycle, you shorten lead times, lower labor costs and reduce the risk of damage from secondary handling, all while maintaining a clean, professional finish on steel, stainless steel, aluminum and cast iron components.
Each HNCarbide carbide chamfer end mill is produced from fine-grain solid carbide and ground on high-precision CNC machines to ensure stable performance at high cutting speeds. We carefully control the chamfer end mill cutting angle, flute geometry and relief so that every chamfer end mill cutter runs smoothly, evacuates chips efficiently and leaves a clean, uniform chamfer even in tougher steels. Available angles include 30 degree chamfer end mill, 45 degree chamfer end mill, 60 degree chamfer end mill, 90 degree chamfer end mill and 120 degree chamfer end mill, giving you a full toolbox for different parts, standards and drawing requirements.
Our range covers single- and double chamfer end mill designs, as well as corner chamfer end mill and end mill with chamfer styles that combine edge preparation with profiling or slotting in one tool. Coating options, shank types and custom diameters can be tailored to your machine and material mix, helping you balance tool life, cutting efficiency and surface quality. With strict inspection on diameter, runout and angle, HNCarbide delivers chamfer tools you can trust from trial runs to full-scale production.
