Geometry Specifications


	*I.C. (Inscribed Circle):*		Insert size is generally categorized by the Inscribed Circle (I.C.), or the diameter of the circle that fits entirely within the insert geometry. This is used for most indexable inserts, except for rectangular and some parallelogram inserts, where length and width are used.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Thickness:
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	*Radius (if applicable):*		Dimension of the radius on the cutter tips, if applicable.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Geometry:
	Your choices are...
	Circular		Round or circular inserts are used in applications such as button mills or in radius groove turning. Some types are adjustable to employ unused edge portions once part of the edge is worn.
	Diamond		Four-sided insert with two acute angles used for material removal.
	Triangle		Inserts with a triangular shape; three equal sides and three tips with included angles of 60°.
	Trigon		Three-cornered insert resembling a triangle, but with a modified triangular shape, such as bowed sides or intermediate angles on the sides, to allow for higher included angles at the tips.
	Square		Cutting tips are square with four equal sides.
	Rectangular		Four sides, two of which are longer than the other two. These inserts are often used for grooving, etc., where the short sides contain the actual cutting edge.
	Rhombic / Parallelogram		Four-sided, with an angle on the sides for cutting point clearance.
	Pentagon		Insert with five equal sides and angles.
	Hex		Six equal sides.
	Octagon		Eight-sided insert, typically indexable.
	Ball Nose Mill		Inserts with a hemispheric "ball nose" whose radius is one half of the cutter diameter; useful for machining female semicircles, grooves or radii.
	Radius Tip Mill		Straight inserts with ground radius on tips, typically for use on milling cutters.
	Chamfer Tip Mill		Insert side or ends contain an angled section on tip to produce an angled cut or a chamfered edge on the workpiece. Typically attached to milling cutter holders.
	Dogbone		Two-edged insert with a narrow mounting center and, as the name implies, a broader cutting feature on both ends. Often used for grooving.
	Other		Other unlisted or specialized tip geometry.

	Features
	Your choices are...
	Unground		Insert blank or semi-finished blank where the final radius, rake and relief angles, etc., have not been ground.
	Indexable		Insert may be indexed or turned to present a fresh cutting edge after one is worn. Indexable inserts can typically be indexed without removing the tool holder.
	Chipbreaker		Notches, grooves, or other edge or surface geometry to facilitate cutting chip clearance and removal.
	Dished		Insert face is "dished," or has a recessed or radiused face. This can allow for higher rake angles.

	Insert Attachment
	Your choices are...
	Screw-on		Insert has a hole for screw attachment to the tool holder.
	No Hole		No center hole for screw attachment. The insert is attached via clamping, brazing, etc.

Material & Coating


	Insert Material
	Your choices are...
	Carbide		Carbide grades are much harder than high-speed steel, and therefore last longer and wear less. Several coatings are available to lengthen cutter life.
	Micrograin Carbide		Micrograin carbide exhibits a small grain size that enables grinding to a very fine edge; often used for finish cutting where surface finish is a consideration.
	CBN		Cubic Boron Nitride (CBN) is a synthetic abrasive. It is used in grinding wheels and as a tool material with very good abrasion resistance.
	Ceramic		Many grades of ceramic are used in the manufacture of cutting tools; ceramic grades are characterized by good wear and abrasion resistance, nonconductivity, and good thermal properties.
	Cermet		Ceramic - metal composite in which ceramic powder in bonded with metal. Good thermal characteristics prevent the work or chips from bonding to the insert surface.
	Cobalt		Cobalt steel tools are somewhat harder than high-speed steel and are often used for milling stainless steel and other alloys.
	Diamond / PCD		Industrial diamond grades such as polycrystalline diamond (PCD) are used for very long life, and sometimes for special applications such as very high-speed cutting.
	High Speed Steel		Cost-efficient cutter material, used for general application metal machining.
	Silicon Nitride		Ceramic grade noted for its good shock resistance and thermal characteristics. It is often used for roughing operations, and other process such as scale removal, interrupted cutting, etc.
	Other		Other unlisted or specialized cutter material.

	Coating
	Your choices are...
	None		Uncoated cutting edges.
	Coated		Drill has a coating to assist in cutting lubricity and/or add abrasion resistance for longer tool life.
	TiN		Titanium Nitride. Widely used general-purpose tool coating, used in most cutting operations. Good adhesion and low friction; typically pale gold in color.
	TiCN		Titanium Carbonitride. Good hardness and smoothness, often used on drills and reamers for castings and nonferrous materials. Often bluish gray in color.
	TiAlN		Titanium Aluminum Nitride. This coating actually forms an oxide-like layer on the tool substrate. Typically used in high-speed or high heat dry-cutting operations; bronze in appearance.
	AlTiN		Aluminum Titanium Nitride. Variation of TiAlN with increased hardness and abrasion resistance. Dark gray or black in color.
	Al₂O₃		Aluminum Oxide. Applications include high-speed cutting or turning of abrasive materials such as ductile irons. Also used as an additive for other coatings, due to its abrasion and temperature resistance. Depending on its grade, it can range from gold to black in appearance.
	CrN		Chromium Nitride. Good corrosion and oxidation resistance. Used for plastics processing and cutting. Low friction also makes it useful for drawing, forming, and extruding tools.
	ZrN		Zirconium Nitride. Typically used on nonferrous materials such as aluminum, brass, nickel alloys, plastics, etc., but can have applications for some iron and stainless steel grades. Good abrasion resistance and lubricity; pale gold in appearance.
	Diamond / DLC		Thin diamond films are applied to cutters to increase life and abrasion resistance. Synthetic coatings similar to diamond films are sometimes referred to as diamond-like coatings (DLC).
	Other		Other unlisted, specialized, or proprietary coating.
