Cutter body including cutting fluid gland

A machining tool comprising:

• a cutter comprising
• an elongate, generally cylindrical shank having a first end adjacent a cutting portion and a second end opposite the first end, wherein said shank has a longitudinal bore therethrough defining a fluid passageway for delivering cutting fluid from an external source to a cutting portion of the cutter and a workpiece;
• a cylindrical land disposed medially between the first end and the second end;
• a forward flat extending from said land forward to the first end;
• and
• a rear flat extending from said land rearward to the second end;
• and a cutter body comprising
• an elongated generally cylindrical chuck adapted for gripping the cutter, said chuck having opposed ends, a medial portion positioned between the opposed ends, and a longitudinal bore at least partially therethrough for receiving the cutter in gripping relation therein, the medial portion of said chuck comprising a pair of longitudinally spaced-apart, circumferential bearing surfaces and a reduced diameter portion between the bearing surfaces, the reduced diameter portion of the medial portion having a first opening therein extending radially inward to the bore of said chuck, the reduced diameter portion in fluid communication with the first opening, the first opening in fluid communication with the bore of said chuck, and the bore of said chuck in fluid communication with the bore of the cutter;
• gripping means for gripping the cutter within the bore of said chuck such that the cutter extends outward from an opposed end of said chuck;
• and
• an annular cutting fluid gland surrounding and engaging the bearing surfaces of the medial portion of said chuck such that said chuck is rotatable relative to said gland, said gland having a second opening therethrough defining a fluid passageway, the second opening in fluid communication with the reduced diameter portion of the medial portion of said chuck;
• the second opening, the reduced diameter portion, the first opening, the bore of said chuck and the bore of the cutter defining a continuous fluid passageway for delivering the cutting fluid from the external source to the cutting portion of the cutter and the workpiece.

A machining tool comprising:

• a generally cylindrical cutter comprising a
• an elongate, generally cylindrical shank having opposed first and second ends and having a longitudinal bore therethrough which defines a fluid passageway;
• a cutting portion adjacent the first end of said shank;
• a cylindrical land disposed medially between the first and second ends of said shank;
• a forward flat extending from said land forward to the first end of said shank;
• and
• a rear flat extending from said land rearward to the second end of said shank;
• a generally cylindrical chuck, said chuck having opposed ends, a medial portion disposed between the opposed ends, and a longitudinal bore at least partially therethrough for receiving said cutter and defining a fluid passageway, the medial portion having a radially extending first opening therethrough defining a fluid passageway, the first opening in fluid communication with the bore of said chuck and the bore of said chuck in fluid communication with the bore of said cutter;
• gripping means for gripping said cutter within the bore of said chuck such that the cutting portion of said cutter extends outward beyond an opposed end of said chuck;
• and
• an annular cutting fluid gland surrounding the medial portion of said chuck such that said chuck is rotatable relative to said gland, said gland having a radially extending second opening defining a fluid passageway, the second opening in fluid communication with the first opening;
• the second opening, the first opening, the bore of said chuck, and the bore of said cutter defining a continuous fluid passageway for delivering a cutting fluid from an external source to the cutting portion of said cutter and a workpiece.
