8 mm Verified Diameter
The verified 8 mm cutting diameter is paired with a 43 mm (1.6929 in) cutting edge for blind-hole dowel drilling.


Royce Ayr D108.080R is a 8 mm (0.3150 in) right-hand solid-carbide brad-point dowel drill from the D108 family. Its verified 70 mm (2.7559 in) overall length supports precision blind-hole boring in compatible woodworking production systems.
Right Hand-hand brad-point dowel drill with a 8 mm cutting diameter and 70 mm overall length in the Royce Ayr D108 family.
For compatible CNC drill banks, CNC boring systems, and portable woodworking machines configured for the appropriate D-series shank and right-hand rotation.
The Royce Ayr D108.080R is a right-hand solid-carbide brad-point dowel drill engineered for blind-hole drilling in particleboard, MDF, and solid wood. Its 8 mm (0.3150 in) cutting diameter supports repeatable dowel-hole production on compatible CNC drill banks and portable woodworking machines.
Royce Ayr lists this D108 configuration with a 43 mm (1.6929 in) cutting edge, 27 mm (1.0630 in) b1 dimension, 10 mm (0.3937 in) shank diameter, Z2 geometry, and 70 mm (2.7559 in) overall length.
Solid-carbide construction provides 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 8 mm cutting diameter is paired with a 43 mm (1.6929 in) cutting edge for blind-hole dowel drilling.
Built around the Royce Ayr D108 dowel-drilling platform for compatible CNC drill-bank and portable woodworking boring systems.
Solid Carbide Tooling is paired with right-hand rotation in the verified D108.080R 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.
