Cutter Type



	Your choices are...
	Angle Cutter		Trigger for Angle Cutters area.
	End Mill		End mills are a very widely used type of milling cutter. They are typically mounted vertically and have two or more helical flutes. End mills are usually configured to cut with their ends and on their sides.
	Face Mill		Face mills are predominantly used to cut with the ends of the cutter rather than their sides. The term "face" refers to the creation of a flat face on the work piece. Face mills often have a larger diameter than the width of the workpiece being faced, so that the surface can be processed in one pass.
	Shell Mill		Shell mills are a larger type of face or end mill that mounts onto an arbor, rather than having an integral shank. Typically there is a hollow or recess in the center of the shell mill for mounting hardware onto a separate arbor or shank.
	Slab Mill		Slab mills typically use the peripheral edges for cutting, usually with helical cutting edges. They are commonly mounted horizontally to produce plane finishes on the workpiece.
	Plunge Mill		Plunge mills are optimized for plunging the cutter directly into the material being worked.
	Single Angle Cutter		Single angle cutters are angled on one side to produce an angle or chamfer on the workpiece edge.
	Double Angle Cutter		Double angle cutters have two angles that come to a point.
	Dovetail Cutter		Dovetail cutters are specialized tools for cutting a dovetail groove into a workpiece, for fitting or joining parts.
	Fly Cutter		Fly cutters are rotary tools that use one or more single-point tools for plane surfacing. The fly cutter is a single-point cutting tool similar to a lathe tool mounted in a special holder.
	Keyseat Cutter		Keyseat cutters produce a slot, which serves as a seat for a complementary engagement key. They are typically used to key shafts to provide positive engagement and prevent unwanted rotation.
	T-slot Cutter		T-slot cutters have side cutting edges, which feed into a workpiece to produce a "T" slot.
	Thread Mill		Thread mills are a rotating, multi-point tool used for producing internal or external threads on a workpiece. Thread mills area an alternative to thread cutting or thread forming.
	Corner Rounding Cutter		Corner rounding cutters produce a smooth radius on workpiece edges.
	Concave Formed Cutter		Concave formed cutters produce a convex feature on the workpiece, most typically a male semicircle.
	Convex Formed Cutter		Convex formed cutters produce a concave feature on the workpiece, most typically a female semicircle.
	Gear Hob		Gear hob cutters are used to cut tooth form on gears. Gear hobs and cutters are ground to produce teeth, usually of an involute form, in standard American pitches or metric modules. Specialty or custom gear hobs are frequently available from gear hob suppliers.
	Button / Copy Mill		Button or copy cutters use circular or "button" inserts rather than traditional square or triangular inserts. This type of significantly radiused edge can allow for enhanced feed rates and depth of cuts at lower power.
	Helical Form Cutter		Helical form cutters are side-cutting mills with customizable profiles. Their intricately ground geometry combines helical flute cutting efficiency with a user-specified edge profile. Typically, the customer is required to specify the required edge profile.
	Other		Other unlisted, specialized, or proprietary milling cutter type.
