Abstract: The present invention generally relates to cutting inserts, and more particularly to a cutting insert in which only cutting edge portion of the cutting insert is made of SiC whisker reinforced ceramics and brazed to the shank with active solder, thereby providing improved cutting performance by increased toughness and high strength of the SiC whisker reinforced ceramics without limitation in shape while reducing manufacturing costs. A cutting insert according to the present invention includes a cutting edge portion made of SiC whisker reinforced ceramics, and a shank to which the cutting edge portion is mounted. The cutting edge portion is brazed to the shank using an active solder, and the whiskers are disorderedly arranged and agglomerated in the cutting edge portion.
