Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid toolholding systems.
Uncoated tools feature just the base substrate without any additional treatment or coatings and are suitable for a wide range of applications.
Round shanks allow use with a wide variety of toolholding systems.
When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging.
Manufactured to National Aerospace Standard 907.

Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys.
Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools.
performance is similar to uncoated tools.
Round shanks allow use with a wide variety of toolholding systems.
When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging.
Manufactured to National Aerospace standard 907.

High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance.
Combination black and gold finish, for improved lubricity, corrosion resistance, and to reduce chipping or flaking.
These round shank tools have flats ground onto three sides to reduce slippage of the bit when used in drill chucks.
When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging.
Construction reamer is especially adapted for heavy duty reaming as encountered in the fabrication of structural steel assemblies.
