Main Product Description
The Royce Ayr D270.50 is a D270 drill adapter for standard metric drills. The verified exact configuration is d=5 mm, D=15 mm, b1=20 mm, s=10 mm, and OA=38 mm.
Royce Ayr specifies the D270 series for CNC drill banks or boring machines that require a 10 mm shank with a flat. The adapter converts the smaller metric drill interface to the machine-side 10 mm format while maintaining a compact 38 mm overall length.
The inserted drill is retained by a set screw in the D270 adapter. Because D270.50 is a non-cutting accessory, drill material, cutting geometry, spindle direction, workpiece compatibility, RPM, and feed parameters are determined by the actual drill installed in the adapter rather than by the adapter itself.

Product Highlights
Set-Screw Drill Retention
Royce Ayr specifies the D270 family with a set screw that secures the inserted drill inside the adapter.
Compact D270 Geometry
The verified 15 mm adapter body, 20 mm shank length, 10 mm machine shank, and 38 mm overall length define the compact D270.50 configuration.
Compatibility & Installation Notes
Confirm that the drill bank or boring machine requires a 10 mm shank with a flat and that the inserted drill uses the exact 5 mm shank size before installing D270.50. Fully seat the drill, tighten the D270 set screw securely, and verify concentricity, runout, insertion depth, machine clearance, and holder condition. Cutting direction, RPM, feed rate, drilling depth, extraction, and workpiece suitability must be established from the mounted drill.
Adapt 5 mm Metric Drills to a 10 mm CNC Interface
Royce Ayr D270.50 combines a 5 mm drill bore, 15 mm adapter body diameter, 20 mm shank length, 10 mm machine shank, 38 mm overall length, and set-screw retention in the D270 adapter format.
It provides a compact mechanical interface for running compatible standard metric drills in CNC drill banks or boring machines that require a 10 mm shank with a flat, without assigning cutting properties to the adapter itself.
