10 mm Verified Diameter
The verified 10 mm diameter is paired with a 50 mm cutting edge for repeatable production boring.


Royce Ayr D130.100L is a 10 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 10 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 D130.100L is a left-hand industrial woodworking drilling tool engineered for accurate production boring. Its verified 10 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 10 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.
D130.100L 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 D130.100L combines a 10 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.
