Sherline straight Insert Tool Holder, 55° insert

Sherline now manufactures its own inserted tip carbide tool holders. They are available individually as a right-hand and left-hand holders with a 35° offset that can be purchased to accept either a 55° or an 80° insert. This holder is not offset to either side, and it comes with a P/N 7605 55° carbide insert, hold-down screw and special Torx key. The 3/8" square shank is held in a P/N 7600 tool post. The staight tip tool can be used as a general turning tool, cutting either right or left. The tip of the cutting tool is .375" from the bottom of the holder, which is the industry standard. The holders are made from case hardened steel with a black oxide finish.

Though relatively expensive, if a cutting edge becomes dull or chipped, the insert can be removed and rotated 180° to expose two new cutting surfaces, providing, in effect, two tools for the price of one.

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 carbide tools can be lifesavers for some jobs. Though more expensive and not able to be resharpened, carbide tools hold their cutting edge when cutting exotic metals or abrasive materials and can speed up the cutting process. This is why they are used for most cutting tasks in the modern professional machine shop.
