ABOUT A.R. WARNER

The Arthur R. Warner Co. is a family-owned American manufacturer of high-speed steel products with specialization in cutting, shaping, pre-grinding, heat treating, and finish grinding of premium grades of flat high-speed steel (and tool steel).

Our Indexable Turning Tool Set was first introduced in July of 1998. Since the introduction, we have expanded our sizes of Turning Tool Sets, introduced 2 sizes of Indexable Boring Bar Kits, a Profiling Kit and a Threading Kit with the appreciated input from numerous Home Shop Machinists.Our latest kits, designed for grooving, have been very well received in both hobbiest and manufacturing markets.

Our kits contain T-15 HSS throw-away inserts. Most machinists are familiar with "Steel" toolbits and Carbide inserts, and now they can achieve the convenience of indexability while using a cutting material which is typically better suited for their smaller lathes and milling machines. Overall, we consider T-15 HSS to be the best grade of readily available HSS for wear resistance, toughness, and hot hardness.

Use T-15 HSS for:

Interrupted Cuts
Underpowered Spindles
Gummy material like stainless, aluminum, and brass
Less than rigid setups

This tool ships with two kinds of inserts. The TPMC-32-NV insert is better in stainless and the TNMC-32-NV is better in alloy steels. You can use either for internal and external threading.

The difference is the relief angle. TPMC inserts have an 11 degree relief angle. TNMC inserts have a 0 degree relief angle.

Make sure you get the correct inserts and retaining screws for your indexable turning tools.

Our chart of indexable inserts shows which inserts and which screw to use with each of our indexable tools.
