End Mills Types
Discover various types of end mills tailored for different machining needs—from general-purpose milling to high-precision mold processing.
Square End Mills
Square end mills are among the most common tools used in CNC milling. With their flat ends and sharp 90° corners, they are ideal for slotting, profiling, plunge cutting, and contouring applications. Suitable for machining ferrous and non-ferrous metals, plastics, and composites. Their simplicity makes them a staple in most machining setups.
Keywords:
- square end mill
- CNC slotting
- profile cutting
- flat end mill
- 90-degree milling
Ball Nose End Mills
Ball nose end mills are ideal for 3D contouring and finishing complex surfaces. They are widely used in mold, die, and aerospace part machining. The rounded tip produces smooth surface finishes and allows for high-precision tool paths.
Keywords:
- ball nose end mill
- 3D contour milling
- mold finishing
- surface machining
Corner Radius End Mills
Designed with a fixed radius at the corners to reduce tool chipping and improve strength. Corner radius end mills are commonly used in mold and die machining where sharp internal corners can be stress concentrators.
Keywords:
- corner radius end mill
- mold tool
- stress relief cutting
- fillet milling
Tapered End Mills
Square end mills are among the most common tools used in CNC milling. With their flat ends and sharp 90° corners, they are ideal for slotting, profiling, plunge cutting, and contouring applications. Suitable for machining ferrous and non-ferrous metals, plastics, and composites. Their simplicity makes them a staple in most machining setups.
Keywords:
- square end mill
- CNC slotting
- profile cutting
- flat end mill
- 90-degree milling
Corner Rounding End Mills
These tools produce consistent rounded edges on the outside of parts. They are particularly useful for aesthetic finishes and edge stress reduction in components that undergo dynamic loading.
Keywords:
- corner rounding end mill
- edge fillet tool
- radius forming cutter
High Feed End Mills
High feed end mills are designed to remove large volumes of material rapidly using shallow depths of cut and very high feed rates. Typically used in roughing operations on hardened steels and tool steels. Their unique geometry results in low radial forces, making them suitable for thin-walled or less rigid parts.
Keywords:
- high feed cutter
- roughing end mill
- fast material removal
- HFM milling
Variable Flute End Mills
These end mills feature uneven flute spacing, which disrupts harmonics and minimizes vibration and chatter. This results in smoother finishes and prolonged tool life, particularly beneficial for high-speed machining of stainless steel, tool steel, and titanium alloys.
Keywords:
- variable flute end mill
- anti-vibration cutter
- chatter reduction
- high-speed milling
Reduced Shank End Mills
These tools allow for deeper milling without enlarging the diameter of the tool shank. Useful in deep cavity mold work or machining undercuts.
Keywords:
- reduced shank end mill
- deep cavity machining
- clearance shank tool
Miniature End Mills
Engineered for small-scale machining operations in electronics, watchmaking, and medical device manufacturing. These end mills offer high precision at diameters below 1mm and work well with micro CNC equipment.
Keywords:
- miniature end mill
- micro milling
- precision CNC tools
- small diameter cutter
Router End Mills
Primarily used for cutting composite materials like carbon fiber, fiberglass, and plastics. Router end mills often feature diamond coatings to extend tool life and improve surface finish.
Keywords:
- router end mill
- CFRP cutter
- composite machining tool
- diamond coated router bit
Roughing End Mills
These roughing end mills feature serrated or “corn cob” cutting edges that break up chips and reduce cutting forces, making them ideal for fast material removal. They offer high metal removal rates without compromising tool life.
Keywords:
- roughing end mill
- serrated cutter
- corn cob end mill
- aggressive machining
Finishing End Mills
Finishing end mills are optimized for producing fine surface finishes and maintaining tight tolerances on final passes. They typically feature more flutes and a sharper cutting edge than roughing mills, making them ideal for polishing steps on molds and complex components.
Keywords:
- finishing end mill
- final pass cutter
- fine surface milling
- polishing cutter
Chamfer End Mills
Used to machine angled features on parts such as chamfers, deburring edges, and countersinking holes. Chamfer mills increase part aesthetics and improve assembly fit by removing sharp edges.
Keywords:
- chamfer end mill
- deburring cutter
- countersink milling
- edge chamfering
Drill Mills
Combines drilling and milling capabilities into one tool, reducing tool changes and increasing productivity. Perfect for machining printed circuit boards, soft metals, and plastic enclosures.
Keywords:
- carbide drill mill
- multi-purpose cutter
- hole and slot tool
- combo end mill
Carbide End Mills
Purpose-built for hardened steels up to HRC 70. These tools maintain cutting edge sharpness and resist thermal fatigue. Commonly used in mold finishing and tool steel component manufacturing.
Keywords:
- hard milling cutter
- Carbide Hard Milling End Mills
- carbide tool for hardened steel
- high HRC machining
PCD End Mills
PCD end mills are used for abrasive non-ferrous materials like aluminum, graphite, and composites. Their extreme wear resistance makes them suitable for mass production environments.
Keywords:
- PCD end mill
- aluminum cutting tool
- graphite machining
- non-ferrous cutter
Ceramic End Mills
Ceramic tools excel at high-speed machining of heat-resistant alloys such as Inconel and Hastelloy. These tools are extremely hard and brittle, requiring rigid setups and dry cutting conditions.
Keywords:
- ceramic end mill
- Inconel cutting tool
- high temperature alloy machining
