What is an End Mill?
An end mill is a type of milling cutter — a rotary cutting tool used in industrial milling machines for operations like slotting, profiling, contouring, and plunge cutting. Unlike drill bits that cut only in the axial (downward) direction, end mills have cutting edges on both the tip and along the sides, allowing them to cut in multiple directions simultaneously.
Maxwell Tools manufactures end mills exclusively from high-speed steel (HSS) in three premium grades: M2 for general-purpose machining, M35 (8% cobalt) for improved heat resistance and harder materials, and ASP 2030 powder metallurgy steel for maximum tool life in demanding applications. All our end mills undergo advanced heat treatment processes developed over nearly 50 years of manufacturing experience.
Types of End Mills We Manufacture
Square End Mills
Most versatile type. Slotting, profiling, side milling, plunge cutting. Available in 2-flute and 4-flute.
Ball Nose End Mills
Hemispherical tip for 3D contouring, mold cavities, and complex curved surfaces. Ideal for die & mold.
Corner Radius End Mills
Rounded corner (0.5–5mm radius) for semi-finishing. Prevents chipping and extends tool life.
Roughing End Mills
Serrated cutting edges for heavy material removal. Reduces vibration during heavy cuts.
Shell End Mills
Large-diameter cutters (40mm+) that mount on an arbor. For face milling and large flat surfaces.
Custom Profile End Mills
Made to your exact specs — non-standard diameters, lengths, flute geometries, and special profiles.

FAQ
Frequently Asked Questions
An end mill is a rotary cutting tool used in CNC and manual milling machines for slotting, profiling, contouring, and plunge cutting. Unlike drill bits that cut only downward, end mills have cutting edges on the tip and sides, allowing multi-directional cutting.
Drill bits cut only axially (downward) to make holes. End mills have cutting edges on both sides and tip, allowing them to cut sideways, make slots, profiles, pockets, and contours — far more versatile than a drill bit.
Select based on slot width or feature size. Use the largest diameter your operation allows for rigidity. 2-flute for aluminum and slotting (more chip clearance), 4-flute for steel and finishing (better surface finish and faster feed rates).
We manufacture in three grades: HSS M2 (general purpose), HSS M35 with 8% cobalt (improved heat resistance for stainless and alloy steels), and ASP 2030 powder metallurgy steel (maximum performance and tool life).
