End mills
Start from the material you are cutting — it drives almost everything else. Then pick the flute count, the material of the tool itself and the coating; the type comes last, if you need something special. Open whichever category you need.
THE MATERIAL YOU ARE CUTTING6
Start here. Pick the material you are cutting and the collection filters down to only the tools that work it. The letters P/M/K/N/S/H are the ISO 513 standard, used by every manufacturer — the same letter means the same material in any catalogue.
In detail, per group: [P] Steel · [M] Stainless · [K] Cast iron · [N] Aluminium · [S] Titanium · [H] Hardened.
Plain and alloy steels — the largest and most forgiving group. They give a long, continuous chip, so chip control is what matters.
Stainless steels. They work-harden locally as you cut them, weld to the edge, and do not carry heat away. They want cobalt, a steady feed with no dwelling, and plenty of coolant.
Cast irons. They give a short, crumbling chip, but the material is abrasive and eats the cutting edge. Here you need abrasion resistance, not heat resistance.
Non-ferrous: aluminium, brass, copper. Soft and fast, but they throw a bulky chip that sticks. They want few flutes, large flute valleys and high revs.
Superalloys and titanium (Inconel, Ti). Very low thermal conductivity: the heat does not leave with the chip, it stays in the edge. Low speeds, steady feed, lots of coolant.
Hardened materials, typically above 45 HRC. They demand carbide and a thermally stable coating — plain HSS simply dulls immediately.
THE FLUTE COUNT5
Click a flute count to filter the collection. The rule: soft material → few flutes; hard material → many flutes.
A single cutting edge and the largest possible chip valley. For plastics and soft aluminium at high speed, where the chip is bulky and has to leave the cut immediately.
Large flutes and plenty of room for the chip. The classic choice for aluminium and non-ferrous metals, and for slotting, where the chip has to escape a closed cut.
The modern compromise: chip evacuation close to a 2-flute, but a larger core and therefore more rigidity. Today the preferred choice for aluminium, with a better finish and higher feed.
Four cutting edges and a large core. For steel and hard alloys, where the chip is small and brittle: a stronger tool, higher feed and a better finish.
Many cutting edges for finishing in ferrous materials at a light depth of cut. Maximum surface quality, minimal deflection and long tool life — but almost no chip room, so not for slotting.
THE TOOL MATERIAL5
Click a material to filter the collection. For a detailed description of the grades (M2, M35, M42, PM60) see the Cutting Tool Materials article.
The classic high speed steel with high hardness and resistance to fracture, ideal for straightforward work.
High speed steel with 5% cobalt for increased resistance to high temperatures. Suitable for stainless (INOX) and hard steels.
High speed steel with 8% cobalt for excellent hardness even at high temperatures. For hard and difficult materials.
Powder metallurgy steel with a perfectly uniform structure and excellent wear resistance. A top-tier solution offering longer tool life than conventional high speed steels.
Tungsten carbide with cobalt, extremely hard and rigid. For very high cutting speeds in CNC and maximum tool life, but sensitive to vibration and impact.
THE COATINGS5
Click a coating to see only the end mills that have it.
A coating offering high thermal stability during cutting. It delivers maximum tool life in hard materials and high-speed machining (HSC), and even makes dry cutting possible.
A coating with a higher aluminium content, giving top-tier thermal stability and hardness. It is the ideal choice for maximum tool life in very hard metals (above 52 Rc), titanium alloys and Inconel, especially in high-speed machining (HSM).
A premium YG-1 coating offering excellent resistance to heat and wear, especially for CNC. It delivers increased tool life in production machining, reducing frequent tool changes.
A multi-layered coating designed to absorb thermal shock and withstand extreme pressure. It is the specialist solution for maximising tool life in very hard materials and steels up to 40–55 HRc.
An advanced nano-layered coating with added silicon that provides extreme surface hardness and thermal shielding. It is the specialist solution for machining hardened steels from 50 to 70 HRC, ensuring maximum tool life and accuracy in the most demanding conditions.
THE TYPES4
Click a type to see only those end mills. With nothing selected you also see the square-end mills, which are the basic form.
A spherical tip with a radius equal to half the diameter. For 3D surfaces, moulds, curves and radii — it follows the profile instead of cutting a corner. It does not leave a flat bottom.
A roughing end mill with serrated cutting edges that break the chip into small pieces. Lower cutting forces, less vibration and a very high material removal rate. It leaves a rippled surface — always follow it with a finishing pass.
An end mill with a Morse taper shank (MT1–MT3) that fits directly into the spindle or a sleeve, with no chuck or collet. For milling machines and drills with a Morse socket.
A set of end mills in a case, with the most common diameters together. The economical way to cover a range of diameters from the start.
