Sherline 062" Carbide Grooving Insert (2 surfaces) 2270
The primary method of cutting metal on miniature machine tools is usually with high speed steel tools as they are inexpensive, easily resharpened and can be ground into "form" tools for special jobs. However, inserted tip tools can be lifesavers for some jobs. This is why they find a lot of use in the modern professional machine shop.
The .062" grooving insert has a cutting depth of 1/8", so it can also be used to part off stock up to 1/4" in diameter.
CAUTION: Chips coming off the carbide inserts can be very HOT! Use extreme caution. Carbide inserts can also shatter. For these reasons proper protective eyewear and clothing is especially important when using these tools.
Some materials like tool steel tend to build up a long, thin chip that wraps around the spinning part like steel wool. Use a chip brush or stop occasionally to remove this material often. Note that red hot chips can cause this "bird's nest" clump of material to burn. Clean up often to keep the pile of chips to a minimum near the cutter.
