Heat-reducing grooving tool holders

A grooving tool holder comprising:

• a lower portion;
• an upper portion pivotable relative to the lower portion, the upper portion comprising a rake face;
• a cutting insert receptacle disposed between the lower portion and the upper portion, the cutting insert receptacle comprising an upper clamping jaw disposed in the upper portion and a lower clamping jaw disposed in the lower portion;
• and
• a cutting insert disposed in the cutting insert receptacle;
• wherein the rake face is disposed adjacent to and over the cutting insert, the rake face shaped to direct material cut by the cutting insert to flow off the rake face laterally away from the rake face.

A method of cutting a groove in a workpiece comprising:

• feeding a grooving tool holder towards a workpiece rotating relative to the grooving tool holder so that a cutting insert of the grooving tool holder contacts the workpiece;
• cutting material of the workpiece using the cutting insert to form the groove;
• and
• directing the cut material to flow off a rake face of the grooving tool holder laterally away from the rake face due to a shape of the rake face.
