Boring Bar Tool Bit Holder: A boring bar tool bit holder consists of a boring bar shaft supported and rotated about its lengthwise centerpoint. Brazed boring bar tool bits are mounted in slots on either end of the rotating boring bar shaft. The boring bar shaft is mounted in a shank which attaches to the rotating machine spindle. This form of tooling assembly is typically not used in today's high precision manufacturing environments.
Attribute Name	Description of Attribute
Number of Cutting Ends	The number of brazed boring tool bits that can be held by this Boring Bar Tool Bit Holder. No more than one boring tool bit may be mounted on each end of the boring bar shaft. [Valid values: 1, 2]
Boring Bar Diameter	The diameter of the boring bar shaft that holds the brazed boring tool bit(s).
Boring Bar Length	The length of the boring bar shaft that holds the brazed boring tool bit(s).
Boring Bar Angle	The angle in which the brazed boring tool bit is held within the boring bar shaft. This angle dictates the angle in which the tool bit will contact the workpiece.
Second Boring Bar Angle (conditional)	The angle in which the second brazed boring tool bit is held within the boring bar shaft. This angle dictates the angle in which this tool bit will contact the workpiece. If the Boring Bar Tool Bit Holder can hold more than one boring tool bit, no distinction is made between which boring tool bit is considered "first" versus "second". Attribute only applies where NUMBER_OF_CUTTING_ENDS = 2.
Tool Bit Shape	The shape of the tool bit(s) that can be held by this Boring Bar Tool Bit Holder. [Valid values: Round, Square] If the Boring Bar Tool Bit Holder can hold more than one boring tool bit, it is assumed that both tool bits will be of the same shape.
Cutter Diameter (conditional)	The shank diameter of the brazed boring tool bit(s) that can be held by this Boring Bar Tool Bit Holder. Attribute only applies where TOOL_BIT_SHAPE = ROUND.
Cutter Square Size (conditional)	The shank square size of the brazed boring tool bit(s) that can be held by this Boring Bar Tool Bit Holder. Attribute only applies where TOOL_BIT_SHAPE = SQUARE.
Shank Mount Style	The method used to attach the shank of this Boring Bar Tool Bit Holder to the machine spindle. This attribute may consist of a generic mount type or a manufacturer-specific designation to indicate the specific mount style. [Examples: Thread, V-Flange, BT-Flange, Straight Shank, Specialty Coupling, etc.]

Holder Length	The overall length of the Lathe Tool Holder.

Table XF1: Brazed Lathe Tool Bit Holder

Brazed Lathe Tool Bit Holder: A brazed lathe tool bit holder is specifically designed to hold and position a brazed lathe tool bit within the lathe. The brazed lathe tool bit holder is typically held on the lathe using a tool block.
Attribute Name	Description of Attribute
Cutter Square Size	The size of lathe tool bit shank that can be held by this tool holding component. Brazed lathe tool bits typically have square or rectangular shanks.
Mount Direction	An indication of the mount configuration of the lathe tool bit body into the Brazed Lathe Tool Bit Holder. [Valid values: Right Hand, Left Hand, Straight]
Holder Shank Height	The shank height of the Brazed Lathe Tool Bit Holder.
Holder Shank Width	The shank width of the Brazed Lathe Tool Bit Holder.

Table XF2: Lathe Tool Shank

Lathe Tool Shank: A lathe tool shank is specifically designed to hold and position a lathe tool blade within the lathe. The lathe tool shank is typically held on the lathe using a tool block.
Attribute Name	Description of Attribute
Blade Style Designation	Common style designation of the lathe tool blade that can be held by this tool holding component. [Examples: General Purpose, Anvil, Manchester, etc.]
Blade Size Designation	An indication of the size of the lathe tool blade that can be held by this tool holding component.
Mount Direction	An indication of the mount configuration of the lathe tool blade into the Lathe Tool Shank. [Valid values: Straight, Angled] Lathe tool blades are typically mounted either straight or angled at 90 degrees within the holder.
Holder Shank Height	The shank height of the Lathe Tool Shank.
Holder Shank Width	The shank width of the Lathe Tool Shank.

Table XF3: Tool Block

Tool Block: A tool block is a lathe tool holder that is typically bolted directly to the lathe machine tool or lathe turret or mounted using a standardized shank style. The tool block consists of a square or rectangular opening or slot for mounting the rectangular shank of a lathe tool body or another lathe tool holder.
Attribute Name	Description of Attribute
Slot Height	The height of the slot in the Tool Block for holding the rectangular shank of a lathe tool body or another lathe tool holder.
Slot Width	The width of the slot in the Tool Block for holding the rectangular shank of a lathe tool body or another lathe tool holder.
Tool Block Height	The overall height of the Tool Block.
Tool Block Width	The overall width of the Tool Block.
Mount Direction	An indication of the mount configuration of the Tool Block on the lathe. [Valid values: Right Hand, Left Hand]
Mounting Method	The method used to attach the Tool Block to the lathe machine tool. [Valid values: Bolt Pattern, Shank]
Shank Style (conditional)	Common style designation for the shank of the Tool Block. [Examples: American National Standard Machine Taper, VDI] Attribute only applies where MOUNT_METHOD = SHANK.
Shank Size Designation (conditional)	A value indicating shank size of the Tool Block. The specific form of this value will be based upon the shank style. [Examples: 30, 40, 50] Attribute only applies where MOUNT_METHOD = SHANK.
