Uncoated cutting tool using brazed-in superhard blank

An uncoated cutting tool for removing material from a workpiece in a material removal operation, the uncoated cutting tool comprising:

• a body comprising cemented carbide, the body having a corner, the body containing a pocket adjacent to the corner;
• a superhard blank having a rake surface and a cutting edge, the blank being brazed into the pocket using a braze alloy whereby there is a braze joint between the body and the blank;
• the braze alloy having a liquidus temperature;
• the superhard blank engaging the workpiece during the material removal operation so that cutting forces are exerted on the superhard blank and heat is generated at the cutting of the superhard blank;
• the braze joint being located a selected distance away from the cutting edge so that the temperature at the braze joint is less than the liquidus temperature of the braze alloy whereby the braze joint has sufficient shear strength to retain the superhard blank in the pocket during the material removal operation.
