The exact D105.087R identity is verified at 11/32 in diameter, 70 mm overall length and right hand rotation.


Royce Ayr D105.087R is a 11/32 in right-hand carbide-tipped brad-point dowel drill from the D105 family. Its verified 70 mm overall length supports precision blind-hole boring in compatible woodworking production systems.
Right Hand-hand brad-point dowel drill with a 11/32 in cutting diameter and 70 mm overall length in the Royce Ayr D105 family.
For compatible CNC drill banks, CNC boring systems, and portable woodworking machines configured for the appropriate D105 shank platform and right-hand rotation.
The Royce Ayr D105.087R is a right-hand carbide-tipped brad-point dowel drill engineered for blind-hole drilling in particleboard, MDF, and solid wood. Its 11/32 in cutting diameter supports repeatable dowel-hole production on compatible CNC drill banks and portable woodworking machines.
The exact product identity verifies 11/32 in diameter, 70 mm overall length, right-hand rotation and brad-point geometry. Royce Ayr identifies D105 as an industrial carbide-tipped dowel-drill family using a 10 × 20 mm family platform. The published standard dimensional table located for this run does not list this special imperial SKU, so no unsupported cutting-edge, b1 or flute-count value is stated.
Carbide-tipped construction supports long service life in production boring. Royce Ayr industrial dowel drills are designed for blind-hole drilling in particleboard, MDF, and solid wood on CNC drill banks and compatible portable machines. Before production, confirm right-hand rotation, toolholder compatibility, insertion depth, runout, drilling depth, and machine parameters for the material being bored.
Technical Specifications
The exact D105.087R identity is verified at 11/32 in diameter, 70 mm overall length and right hand rotation.
The D105 family is configured around its verified shank geometry and 70 mm overall length for compatible production boring systems.
D105 Industrial Carbide-Tipped / HW Family is paired with right-hand rotation in the verified D105.087R configuration.
Verify that the boring head, spindle, chuck, or adapter accepts the required shank and is intended for right-hand tooling. Confirm clean toolholding, minimal runout, correct insertion and height adjustment, appropriate drilling depth, secure workpiece support, and suitable spindle/feed parameters before production. Do not assume CE, b1 or Z values from adjacent standard D105 sizes; those specifications are intentionally not assigned to this special imperial SKU.
