End Mills and Milling Cutters

Ball End Mills

Good for rounded slots, sloping cuts, and contours, ball end mills have a rounded cutting edge.

Square End Mills

A 90° profile creates square slots, pockets, and edges.

Corner-Rounding End Mills

Round sharp corners on the edge of your workpiece.

Concave-Radius End Mills

A scalloped profile creates rounded, outward-curving edges.

Chamfer End Mills

More angled than tapered end mills, chamfer end mills have cutting angles of 45° and higher for making chamfer, bevel, and other angled cuts.

Keyseat End Mills

Also known as Woodruff keyseat cutters, these tools mill precise notches in rotary shafts and can also be used for slot milling.

Tapered End Mills

Also known as taper degree end mills, these end mills are angled from anywhere between 1/2° and 45° for machining angled slots in dies and molds.

Undercutting End Mills

A fine-point tip cuts lettering and numbering and makes designs in a variety of metals and composites, such as aluminum, fiberglass, and titanium.

Fly Cutters

These end mills clamp onto tool blanks to machine flat surfaces. As the cutter rotates, the tool blank creates a wide, shallow cut on the face of the workpiece.

Engraving End Mills

A fine-point tip cuts lettering, designs, and logos in a variety of metals and composites, such as aluminum, fiberglass, and titanium.

Drill/Mill End Mills

These multifunction tools have a 90° pointed tip that allows them to be used for drilling as well as for slotting, profiling, and chamfering cuts.

Convex-Radius End Mills

With curved, side-cutting teeth, these tools create grooves.

Rounded-Edge Square End Mills

Often used for slotting and pocketing cuts in mold and die making, these end mills have a 90° profile with rounded corners, which reduce flute breakage and chipping.

T-Slot End Mills

Mill slots in machine tool tables, indexing tables, and other workholding surfaces.

Dovetail End Mills

Create dovetail slots for joining components, holding work, or housing an O-ring or other seal.
