This symbol represents the direction in which the insert can machine. If the insert can be used for both left and right (thus neutral) then the symbol is generally omitted.

Chip breakers play an important role in chip control. Cutting tool manufacturers employ their own breaker geometries and as such the symbol is optional.

We have found using a 5 or 7 Flute Variable Pitch End Mill ideally with a Corner Radius works best taking a Full Flute Length Axial DOC along with a Light Radial DOC (7%-11%) of the Tool Diameter when profile milling.  This allows you to utilize the Helix of the End Mill so that it leads into the cut lowering the tool pressure and keeping the heat formation down.  A Chipbreaker Style Rougher/Finisher End Mill is also ideal as it will keep tool pressure down and break the chips so that they get out of the way (a lot of the times the chips stay around the workpiece when using an End Mill without chipbreakers and re-cutting chips will break an End Mill).  Also, if you can have a Corner Radius then do it as it will double your End Mill over a Square Corner End Mill in Stainless (and then come in with a Square Corner as a Finisher).   Here are the End Mills we recommend for Profile Milling Stainless Steel:

ISOturningtool holder nomenclature

This represents the corner radius (nose radius) of an insert. It is standardized in intervals, for example after 0.4mm with intervals of 0.4mm, and after 4.0mm in intervals of 0.8mm.

The insert geometry is represented using letters of the alphabet. A wide range of geometries are listed as standard for example; triangle, square, round, polygon and rhombus.

Chip breakers play an important role in chip control. Cutting tool manufacturers employ their own breaker geometries and as such the symbol is optional.

This symbol represents whether or not the insert has a chip breaker. It also refers to whether the insert has a hole or not. A negative insert can have one-sided or double-sided chip breaker.

The symbol that represents the tolerance class is determined by a combination of three tolerances; the nose height (m), inscribed circle (d) and thickness (s). To produce close tolerance inserts, grinding is necessary.

Here are recommendations for Machining 303, 304 and 316 Stainless Steels.  Stainless Steel is tough on tooling but with the correct tools as well as speeds/feeds you can do well in machining Stainless Steel. First let's break down the differences between 303, 304 and 316:

For turning operations, mainly G-class (sometimes J-class) or M-class inserts are used. Inserts with tolerance classes other than G, J and M are mostly used on face milling cutters.

This symbol represents the direction in which the insert can machine. If the insert can be used for both left and right (thus neutral) then the symbol is generally omitted.

This symbol represents the actual thickness of the insert. It works on the same principle as that of the inscribed circle.

For the inch coding method, the diameter of an inscribed circle is shown by a numerical symbol. For example, an inscribed circle of  3/8 inch (9.525mm) is represented by the symbol 3. An inscribed circle of 4/8 inch (12.70mm) is shown as 4.

However, for the metric coding, the diameter of an inscribed circle is represented by the cutting edge length using a two-digit number. Therefore, even if the inscribed circle is the same, the symbol for the cutting edge will vary.

The symbol that represents the tolerance class is determined by a combination of three tolerances; the nose height (m), inscribed circle (d) and thickness (s). To produce close tolerance inserts, grinding is necessary.

There are a number of different types of honing, for example "round" honing and "chamfer" honing. The type of honing employed is shown by the appropriate symbol. Cutting tool manufacturers amploy their own honing geometries (size and angle) according to insert grade and size. Generally the honing symbol is omitted from an identification code.

This is the symbol that represents the clearance angle of an insert. An insert with 0° clearance angle, which is shown by symbol N, is called a negative insert. An insert with a clearance angle other than 0° is called a positive insert. Many turning inserts have clearance angles shown by symbols P, C and N.

*Remember to Cut the Feed Rate in 1/2 when coming into corners. Also, if you need to slot then your axial DOC should have 1/2 the Tool Diameter (For Example a 1/2" Diameter End Mill should take a Max Axial DOC of 1/4" when slotting to allow chips to clear)

*With Cobalt Drills you need to peck at Half the Drill Diameter to make sure chips evacuate (a 1/4" Drill should take 1/8" Pecks). You can run the drill 2XD on the initial plunge and then take 0.5XD Pecks to cut cycle Time

In Drilling 303, 304 & 316 Stainless Steel a Carbide Coolant Thru Drill is the ideal option.  It will give you the fastest cycle times along with the longest tool life.  With a Coolant Thru Drill you do not need to peck as the coolant thru will evacuate the chips but with a Non Coolant Thru Carbide Drill or HSS/Cobalt Drill you do need to peck to evacuate the chip (you will want to take 0.5 x Drill Diameter Pecks with these drills as shown below).  If you do not have a coolant thru spindle then a non coolant thru drill will also work well, you will just need to peck.  If it is shorter run and you want to keep your costs down then a Cobalt Drill will also work well.  Here are links to the Cobalt and Carbide Drill we recommend along with speeds and feeds:
