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


Carbide-tipped left-hand hinge boring drill for accurate blind-hole production in particle board, MDF, and solid wood. The verified D185.350L configuration combines a 35 mm cutting diameter, 10×26 mm 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.
Designed for CNC drill banks and compatible portable machines using the verified 10×26 mm shank interface. A screw in the end of the tool provides height adjustment.
The Royce Ayr D185.350L is an Industrial 2+2 Wing Hinge Boring Drill for larger-diameter blind-hole drilling. The controlled current configuration is D=35 mm, 10×26 mm shank, 70 mm overall length, and left-hand rotation.
Royce Ayr specifies the D180/D185 2+2 wing family for CNC drill banks and portable machines, with applications in particle board, MDF, and solid wood. The cutting edges are carbide tipped for long service life in compatible woodworking and panel-processing operations.
A screw in the end of the drill provides height adjustment for controlled setup. Confirm the drilling spindle accepts the 10 mm shank, verify left-hand rotation, tool seating, adjustment, runout, drilling depth, feed rate, RPM, extraction, and workpiece support before production.
Technical Specifications
Royce Ayr's 2+2 wing hinge-drill format is built for accurate larger-diameter blind holes in production woodworking and panel processing.
The manufacturer specifies carbide-tipped cutting edges for long service life in particle board, MDF, and solid wood applications.
The D185 platform extends overall length to 70 mm while retaining the current 10×26 mm shank format for compatible drilling equipment.
Confirm that the drill bank, boring spindle, or compatible portable machine accepts the exact 10×26 mm shank and requires left-hand rotation before installing D185.350L. Verify the end-screw height adjustment, tool seating, runout, drilling depth, feed rate, RPM, extraction, and workpiece support before production. The controlled current D185 specification uses the 10×26 mm shank and 70 mm overall length.
Royce Ayr D185.350L combines a 35 mm cutting diameter, 10×26 mm shank, 70 mm overall length, left-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, with end-screw height adjustment supporting controlled setup.
