Main Product Description
The Royce Ayr D145.111L is a left-hand V-point thru-hole drill engineered for production woodworking boring. Its verified 7/16 in cutting diameter and 57 mm overall length support accurate machining in compatible CNC and portable boring systems.
The exact Magento/Titan catalog identity verifies 7/16 in diameter, 57 mm overall length, left-hand rotation and V-point thru-hole geometry. Published Royce family data supports the D145 carbide-tipped 10 × 20 mm platform, but this exact special size is not present in the standard dimensional table used for this batch. No unsupported CE, b1 or flute-count value is stated.
D145 Carbide-Tipped / HW Family supports long service life in production drilling. Before production, confirm left-hand rotation, toolholder compatibility, insertion depth, runout, drilling depth, secure workpiece support, and suitable spindle/feed parameters.

Product Highlights
D145 57 mm Configuration
The SKU-specific overall length and family geometry are retained without importing unsupported dimensions from adjacent Royce drill sizes.
Left Hand Rotation
D145.111L 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 accepts the required family shank and 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. Do not borrow CE, b1 or Z values from adjacent standard D145 sizes; those specifications are intentionally not assigned to this special SKU.
