Imperial 3/4-Inch Variant
Titan inventory directly identifies D185.195L as the 3/4-inch left-hand hinge-drill variant with a 70 mm overall length.


Carbide-tipped left-hand hinge boring drill for accurate blind-hole production in particle board, MDF, and solid wood. Titan inventory identifies D185.195L as the 3/4-inch × 70 mm LH hinge-drill variant. The current Royce D185 family specification controls the machine-side geometry at a 10×26 mm shank and 70 mm overall length 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.
Exact Titan inventory identifies the 3/4-inch LH variant. The active D185 family uses the current 10×26 mm shank interface and 70 mm overall length, with end-screw height adjustment.
The Royce Ayr D185.195L is an Industrial 2+2 Wing Hinge Boring Drill represented in Titan inventory as the 3/4-inch × 70 mm left-hand hinge-drill variant. Exact SKU identity, imperial cutting diameter, 70 mm overall length, and LH rotation are controlled by Titan inventory evidence.
The active Royce D185 family specification uses a 10×26 mm shank and 70 mm overall length. Royce specifies the industrial 2+2 wing family for CNC drill banks and portable machines, with blind-hole applications in particle board, MDF, and solid wood. The cutting edges are carbide tipped for long service life.
A screw in the end of the drill provides height adjustment for controlled setup. Confirm the drilling spindle accepts the current D185 10 mm shank format, verify left-hand rotation, tool seating, adjustment, runout, drilling depth, feed rate, RPM, extraction, and workpiece support before production.
Technical Specifications
Titan inventory directly identifies D185.195L as the 3/4-inch left-hand hinge-drill variant with a 70 mm overall length.
The D185 family uses industrial 2+2 wing hinge-boring geometry with carbide-tipped cutting edges for compatible wood and panel materials.
Current D185 family data controls the machine-side format at a 10×26 mm shank with 70 mm overall length for CNC drill banks and portable machines.
Confirm the required 3/4-inch cutting diameter and left-hand rotation before installing D185.195L. The exact SKU is inventory-controlled by Titan, while the current D185 family specification controls the 10×26 mm shank and 70 mm OAL. Older Royce literature used a 10×30 mm D185 shank. Verify holder fit, end-screw height adjustment, tool seating, runout, drilling depth, feed rate, RPM, extraction, and workpiece support before production.
Royce Ayr D185.195L is Titan's exact 3/4-inch × 70 mm LH D185 hinge-drill variant, paired with the current D185 10×26 mm shank format, carbide-tipped cutting edges, and industrial 2+2 wing hinge-boring geometry.
It is intended for larger-diameter 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.
