Grades and Grade Descriptions
Coatings provide high-speed
capability and are engineered
for fi nishing to light roughing.
• Reduce cycle times — high speed capability.
• Longer tool life — new multilayer coating
provides better wear resistance.

Grade Description
P
An advanced PVD TiAlN coating over a very deformation-resistant unalloyed carbide
substrate. TN6010 is ideal for fi nishing to general machining of most workpiece
materials at higher speeds. Excellent for machining most steels, stainless steels, cast
irons, non-ferrous materials, and super alloys under stable conditions. It also performs
well in machining hardened and short chipping materials.

M
An advanced PVD TiAlN-coated grade with a tough, ultra-fi ne-grain unalloyed
substrate. For general-purpose machining of most steels, stainless steels,
high-temp alloys, titanium, irons, and non-ferrous materials. Speeds may vary
from low to medium and will handle interruptions and high feed rates.

HC-P25
Uncoated carbide for light and medium machining. For cast iron, all non-ferrous
metals, and non-metals. Also capable of machining hardened materials at low
cutting speeds.

• All TopThread inserts are precision-ground to
provide accurate edge location and secure
locking of the insert in the toolholder pocket. • Right-hand TopThread toolholders use
right-hand inserts. Left-hand TopThread
toolholders use left-hand inserts.
• TopThread inserts can be used in either
toolholders or boring bars. • Right-hand TopThread boring bars
use left-hand inserts. Left-hand TopThread
