LUOTA Tools manufactures solid carbide end mills for steel, stainless steel, titanium, superalloys and aluminum — from carbide rod to finished, coated tool, under one roof. Standard sizes are kept in stock year-round, and small trial orders are welcome.
Every series is engineered around an ISO material group — substrate grade, geometry and coating are chosen together, not mixed and matched. Pick your material group to see the series we recommend.
Showing the full range — 18 series and tool types.
High-efficiency lines, each tuned to one material family
High-efficiency milling of forged and cast aluminum (Si < 12%). The U-groove gives a larger chip pocket, polished flutes prevent built-up edge, and the DLC coating pairs low friction with high hardness for a major gain in tool life.
The dynamic-milling workhorse for carbon steel, alloy steel, stainless steel and cast iron. Unequal pitch with a variable 35–37° helix suppresses vibration in slotting, facing and trochoidal milling; a nano-composite AlTiN coating adds wear resistance.
A 44–45° high helix keeps cutting-edge load low and extends tool life across carbon steel, alloy steel, stainless steel and cast iron. The 12% cobalt, 0.4 µm substrate is tough and hard at the same time — a true all-rounder.
Built for titanium alloys and stainless steel. Unequal pitch and unequal helix resist vibration, the widened trapezoidal flute moves chips freely, and the composite nano HT coating stands up to cutting heat while helping chips and heat escape.
For nickel-based and iron-based high-temperature alloys. The substrate is heat- and impact-resistant, so edges resist chipping and metal removal stays high in roughing — while its red hardness keeps it wear-resistant for finishing passes.
Made for alloy and hardened steels at 45–65 HRC. A large core gives rigidity, a big wedge-angle edge resists breakage, and the hardest substrate in our range (HRA 93.5–94) carries an AlTiN+TiSiN coating for long life in hard milling.
An anti-vibration 3-flute for forged and cast aluminum. Unequal pitch and helix raise efficiency, the polished U-slot suppresses built-up edge, and DLC coating cuts friction for a cleaner workpiece surface finish.
The versatile everyday 4-flute for carbon steel, alloy steel, stainless steel and cast iron. Anti-vibration unequal geometry delivers a high metal removal rate and good surface roughness; the SP coating resists wear and oxidation.
Economical universal lines graded by workpiece hardness
For hardened steel and chilled cast iron at the top of the hardness range. A negative-rake edge design stays strong and resists chipping, on an ultra-fine 9% cobalt substrate with AlTiN+TiSiN nano coating.
For carbon steel, alloy steel, stainless steel and cast iron up to 65 HRC. The blue TiAlSiNX nano coating runs on a 12% cobalt fine-grain substrate; micro sizes down to Ø0.2 mm cover precision mold work.
A balanced line for steels up to 60 HRC — carbon steel, alloy steel, stainless steel and cast iron. AlTiN (black nano) coating, plus 2-flute micro flat and ball-nose versions for small, precise work.
An economical line for carbon steel, alloy steel, stainless steel and cast iron up to 58 HRC, with the flat, ball and corner-radius geometries most shops reach for every day.
Our broadest economical line for carbon steel, alloy steel and cast iron: flat, ball and corner-radius end mills, plus the HRC55 spot drills, roughing cutters, chamfer mills and micro tools below.
Bright, polished tools for aluminum and copper alloys — sharp uncoated edges that resist built-up edge and leave a clean finish, in flat, ball-nose and corner-radius geometries.
Roughing, spotting, chamfering and micro work
Serrated edges break chips into short, safe fragments, and an arc-shaped edge profile keeps the edge strong under heavy cuts — higher roughing efficiency for steel (HRC55 line) and aluminum versions.
90° spot drills for accurate hole starting and chamfering in one pass — a TiAlSiN-coated version for steel and cast iron, and a bright version for aluminum and copper alloys.
Chamfer mills for clean edge breaking and countersinking — TiAlSiN-coated for carbon steel, alloy steel and cast iron, and a bright version for aluminum and copper alloys.
2-flute micro flat and ball-nose end mills from Ø0.2 mm, with a large chip pocket for smooth evacuation and stable tool life — available in the HRC55, HRC60 and HRC65 lines for precision and mold work.
We don't assemble tools from bought-in blanks. Carbide rod production, CNC grinding and coating all happen inside our own production bases — which is why quality stays consistent from the first piece to the seven-millionth.
100+ rod production lines turn out the carbide blanks behind every series — 10% and 12% cobalt grades, grain sizes down to 0.3 µm, hardness up to HRA 93.5–94 for hard-milling tools.
120+ CNC grinding machines, including ANKA grinders, produce the geometries our catalog is built on — unequal pitch, variable helix, U-slot and trapezoidal flute profiles.
Four coating lines apply DLC, AlTiN, AlTiN+TiSiN, TiAlSiN, TiAlSiNX and our SP and HT nano coatings in-house, so coating quality and lead times stay under our control.
| Cutting diameter | 0 / −0.03 mm |
|---|---|
| Shank diameter | h6 |
| Flute length | ±0.5 mm |
| Overall length | ±1 mm |
| Corner radius | ±0.01 mm |
Tolerances above are the standard our catalog is manufactured to. Regular sizes are kept in stock year-round, so repeat orders ship without a production wait — and when a size does need to be produced, the full chain is in-house, not queued at an outside grinder or coating shop. Cutting parameters for every ISO material group are published in our catalog; ask us for the pages for your series.
Distributors and tool brands build their own labels on our production lines. You bring the brand; we bring the factory — rods, grinding, coating, marking and packaging.
LUOTA Tools is a manufacturer specializing in solid carbide cutting tools. We operate two production bases in Changzhou and Suining, China — equipped with 100+ carbide rod production lines, 120+ CNC grinding machines and in-house coating facilities, forming a complete production chain from carbide rods to finished tools.
Our sales and logistics center in Dongguan ensures fast response to inquiries and efficient worldwide shipping.
