5 mm Verified Diameter
The verified 5 mm cutting diameter is paired with a 37 mm (1.4567 in) cutting edge for repeatable blind-hole dowel drilling.


Royce Ayr D107.050R is a 5 mm (0.1969 in) right-hand solid-carbide brad-point dowel drill from the D107 family. Its verified 57 mm (2.2441 in) overall length supports precision blind-hole boring in compatible woodworking production systems.
Right Hand-hand brad-point dowel drill with a 5 mm cutting diameter and 57 mm overall length in the Royce Ayr D107 family.
For compatible CNC drill banks, CNC boring systems, and portable woodworking machines configured for the appropriate D107 shank platform and right-hand rotation.
The Royce Ayr D107.050R is a right-hand solid-carbide brad-point dowel drill engineered for blind-hole drilling in particleboard, MDF, and solid wood. Its 5 mm (0.1969 in) cutting diameter supports repeatable dowel-hole production on compatible CNC drill banks and portable woodworking machines.
Royce Ayr lists this D107 configuration with a 37 mm (1.4567 in) cutting edge, 20 mm (0.7874 in) b1 dimension, 10 mm (0.3937 in) shank diameter, Z2 / two cutting edges, and 57 mm (2.2441 in) overall length.
Solid-carbide construction is specified for maximum wear resistance and strength, and Royce Ayr incorporates a screw in the end of the tool for height adjustment. Before production, confirm right-hand rotation, toolholder compatibility, insertion depth, runout, drilling depth, and machine parameters for the material being bored.
Technical Specifications
The verified 5 mm cutting diameter is paired with a 37 mm (1.4567 in) cutting edge for repeatable blind-hole dowel drilling.
The D107 family is configured around its verified shank geometry and 57 mm overall length for compatible production boring systems.
Solid Carbide Tooling is paired with right-hand rotation in the verified D107.050R configuration.
