Main Product Description
The Royce Ayr D139.080L is a left-hand industrial woodworking drilling tool engineered for accurate production boring. Its verified 8 mm diameter and 70 mm overall length are carried directly from the product identity.
The Magento/Titan catalog identity explicitly gives an 8 mm diameter, 12 mm cutting edge, 70 mm overall length and left-hand countersink configuration. No unsupported b1, shank or flute-count value is introduced.
Before production, confirm left-hand rotation, toolholder compatibility, insertion depth, runout, drilling depth, secure workpiece support, and suitable spindle/feed parameters for the material being machined.

Product Highlights
D139 70 mm Configuration
The SKU-specific overall length and geometry are retained without importing unsupported dimensions from adjacent Royce drill families.
Left Hand Rotation
D139.080L is configured for left-hand boring positions and should be installed only in the corresponding machine station or spindle direction.
Compatibility & Installation Notes
Verify that the boring head, spindle, chuck, or adapter is intended for left-hand tooling. Confirm clean toolholding, minimal runout, correct insertion, appropriate drilling depth, secure workpiece support, and suitable spindle/feed parameters before production. Confirm the required countersink geometry and machine interface before production; shank and Z values are intentionally not inferred.
Production Drilling
Royce Ayr D139.080L retains its verified 8 mm diameter, 12 mm CE, left-hand rotation and 70 mm overall length.
It is intended for accurate industrial woodworking drilling on compatible CNC drill banks, boring equipment, and production systems.
