Carbide-Tipped External Threading Lathe Tools
The carbide tip brazed onto the ground steel shanks of these tools is more wear resistant than high-speed steel. Right-handed tools cut from right to left, left-handed tools cut from left to right, and neutral tools can cut in either direction.
Right-hand and left-hand threading tools are for working close to the chuck.
C2 carbide tips are abrasion resistant and less likely to chip or crack than C6 carbide when cutting aluminum, brass, and bronze.
C6 carbide tips hold up better than C2 carbide when making cuts in steel.
Micrograin carbide tips outperform C2 and C6 carbide tips when cutting difficult-to-machine metal, such as stainless steel or titanium. They provide a good finish on most materials.
