The Sherline 80° LH Tool Holder w/ Carbide Insert is a precision-engineered tool designed for efficient metal cutting tasks. This tool holder features an 80° carbide insert, which is particularly effective for roughing cuts. The tool holder is crafted from case-hardened steel and finished with a black oxide coating, ensuring durability and resistance to wear. The 3/8″ square shank fits securely in a 3/8″ insert tool post, and the 5° offset angle of the tip facilitates precise cutting operations, such as turning an outer diameter up to a shoulder and finishing the shoulder with ease.

The carbide insert, while more costly than high-speed steel tools, offers significant advantages in terms of cutting performance. It maintains its cutting edge when working with exotic metals or abrasive materials, thereby accelerating the cutting process. Additionally, the insert can be rotated 180° to reveal two new cutting surfaces, effectively doubling its lifespan. This feature makes it a valuable asset in professional machine shops where efficiency and precision are paramount.

Note: A tool is named by the direction from which the chip leaves the tool; thus, a left-hand tool has its cutting edge on the right and the chip peels off to the left.
