Royce Ayr Carbide-Tipped Brad Point Dowel Drill Left-Hand – 18mm Diameter – 70mm Overall Length

The Royce Ayr D105.180L is a left-hand industrial carbide-tipped brad-point dowel drill engineered for blind-hole drilling in particleboard, MDF, and solid wood. Its 18 mm (0.7087 in) cutting diameter supports repeatable dowel-hole production on compatible CNC drill banks and portable woodworking machines.

The exact product identity verifies 18 mm diameter, 70 mm overall length, left-hand rotation and brad-point geometry. Royce Ayr identifies D105 as the industrial carbide-tipped dowel-drill family with a 10 × 20 mm family shank platform. The published standard D105 dimensional table stops at 16 mm, so no unsupported cutting-edge, b1 or flute-count value is stated for this special size.

Royce Ayr specifies the D105 family with a larger carbide tip and improved geometry for longer life, carbide-tipped construction, a screw in the end for height adjustment, and a 10 mm shank with flat for set screws. Before production, confirm left-hand rotation, toolholder compatibility, insertion depth, runout, drilling depth, and machine parameters for the material being bored.
