Industrial 2+2 Wing Geometry
Royce Ayr's 2+2 wing hinge-drill format is designed for accurate larger-diameter blind holes in production woodworking and panel processing.


Carbide-tipped right-hand hinge boring drill for accurate blind-hole production in particle board, MDF, and solid wood. The exact Titan-stocked D185.200R-1/2SK variant combines a 20 mm cutting diameter, 1/2-inch machine shank, 70 mm overall length, and industrial 2+2 wing geometry for CNC drill banks and compatible portable machines.
Industrial carbide-tipped hinge-style boring drill for larger-diameter blind holes. The 2+2 wing geometry is intended for accurate production drilling in common wood and panel materials.
Special Titan-stocked right-hand D185 variant using a 1/2-inch machine shank instead of the standard 10 mm D185 shank diameter. The exact variant retains the 70 mm D185 overall-length format.
The Royce Ayr D185.200R-1/2SK is a special 1/2-inch-shank variant of the Industrial 2+2 Wing Hinge Boring Drill family. Titan inventory verifies the exact SKU as a 20 mm diameter, 70 mm overall-length, right-hand hinge drill with a 1/2-inch shank.
Royce Ayr specifies the D185 2+2 wing family for CNC drill banks and portable machines, with applications in particle board, MDF, and solid wood. The family is carbide tipped and uses an end screw for height adjustment.
This exact suffix variant changes the machine-side shank diameter from the standard D185 10 mm format to 1/2 inch. Confirm that the drilling spindle or holder accepts the 1/2-inch shank, then verify right-hand rotation, tool seating, runout, boring depth, feed rate, RPM, extraction, and workpiece support before production.
Technical Specifications
Royce Ayr's 2+2 wing hinge-drill format is designed for accurate larger-diameter blind holes in production woodworking and panel processing.
Titan inventory identifies D185.200R-1/2SK as the special right-hand 20 mm D185 configuration with a 1/2-inch machine shank.
The exact variant retains the D185 70 mm overall-length format while changing the machine-side shank diameter from the standard 10 mm version.
Confirm that the drill bank, boring spindle, or toolholder accepts the exact 1/2-inch shank and requires right-hand rotation before installing D185.200R-1/2SK. Do not substitute the standard 10 mm D185.200R without confirming holder compatibility. Verify the end-screw height adjustment, tool seating, runout, drilling depth, feed rate, RPM, extraction, and workpiece support before production.
Royce Ayr D185.200R-1/2SK combines a 20 mm cutting diameter, 1/2-inch machine shank, 70 mm overall length, right-hand rotation, carbide-tipped cutting edges, and industrial 2+2 wing hinge-boring geometry.
It is intended for accurate blind holes in particle board, MDF, and solid wood on compatible CNC drill banks and portable machines where the 1/2-inch shank interface is specifically required.
