8 mm Verified Diameter
The verified 8 mm diameter is paired with a 50 mm cutting edge for repeatable production boring.


Royce Ayr D130.080L is a 8 mm left-hand industrial woodworking drilling tool. Its verified 85 mm overall length and SKU-specific geometry are retained exactly for compatible CNC and production boring systems.
Left Hand-hand industrial drilling configuration with a verified 8 mm diameter and 85 mm overall length.
For compatible CNC drill banks, CNC boring systems, and woodworking drilling equipment configured for left-hand tooling and the required machine interface.
The Royce Ayr D130.080L is a left-hand industrial woodworking drilling tool engineered for accurate production boring. Its verified 8 mm diameter and 85 mm overall length are carried directly from the product identity.
Royce Ayr lists this D130 configuration with a 50 mm cutting edge, 27 mm b1 dimension, 10 mm shank diameter, Z2 / two cutting edges, and 85 mm overall length. The 10 × 27 mm platform is the verified insertion geometry for this series.
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.
Technical Specifications
The verified 8 mm diameter is paired with a 50 mm cutting edge for repeatable production boring.
The SKU-specific overall length and geometry are retained without importing unsupported dimensions from adjacent Royce drill families.
D130.080L is configured for left-hand boring positions and should be installed only in the corresponding machine station or spindle direction.
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.
Royce Ayr D130.080L combines a 8 mm cutting diameter, 50 mm cutting edge, left-hand rotation, Z2 geometry, carbide-tipped / HW construction, and the D130 10 × 27 mm shank / 85 mm overall-length platform.
It is intended for accurate industrial woodworking drilling on compatible CNC drill banks, boring equipment, and production systems.
