Technical Specifications
The verified 5.2 mm diameter is paired with a 30 mm cutting edge for repeatable blind-hole drilling.
The SKU-specific overall length and family geometry are retained without importing unsupported dimensions from adjacent Royce drill sizes.
D100.052R is configured for right-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 accepts the required family shank and is intended for right-hand tooling. Confirm clean toolholding, minimal runout, correct insertion, appropriate drilling depth, secure workpiece support, and suitable spindle/feed parameters before production.
Royce Ayr D100.052R combines a 5.2 mm cutting diameter, 30 mm cutting edge, right-hand rotation, carbide-tipped / hw tooling, and the D100 10 × 20 mm shank / 57 mm overall-length platform with Z2 geometry.
It is intended for accurate industrial woodworking drilling on compatible CNC drill banks, boring equipment, and production systems.
