2 mm Precision Diameter
The 2 mm (0.0787 in) cutting diameter supports fine dowel-hole and small-diameter boring operations where accurate tool positioning is critical.


Royce Ayr D108.020R is a 2 mm (0.0787 in) right-hand solid-carbide brad-point dowel drill from the D108 metric family. The D108 platform uses a 10 × 27 mm shank and 70 mm (2.756 in) overall length for precision dowel-hole boring in compatible woodworking boring systems.
Precision small-diameter solid-carbide dowel drill with right-hand rotation, a 2 mm cutting diameter, and D108-series 10 × 27 mm shank geometry.
For compatible dowel-boring heads, CNC boring systems, and woodworking drilling equipment configured for a 10 mm shank and the required right-hand spindle position or rotation.
The Royce Ayr D108.020R is a solid-carbide metric dowel drill built for precise 2 mm (0.0787 in) brad-point boring. Its right-hand configuration identifies the tool for matching right-hand boring positions where the machine, boring head, and spindle arrangement require that rotation.
D108-series construction uses a 10 × 27 mm shank and 70 mm (2.756 in) overall length. This standardized platform supports repeatable toolholding in compatible woodworking boring systems while the small 2 mm cutting diameter addresses fine dowel-hole and precision drilling requirements.
Correct installation is critical with small-diameter carbide tooling. Confirm right-hand rotation, clean and undamaged toolholding, minimal runout, appropriate drilling depth, and secure workpiece support before production. The archived D108 table does not verify a cutting-length value for the 2 mm D108.020R variant, so no unsupported cutting-length specification is stated here.
Technical Specifications
The 2 mm (0.0787 in) cutting diameter supports fine dowel-hole and small-diameter boring operations where accurate tool positioning is critical.
The D108 family uses a 10 × 27 mm shank with a 70 mm overall length for compatible industrial dowel-boring and woodworking drilling systems.
Right-hand rotation matches corresponding boring-head positions, while solid-carbide construction provides a rigid cutting platform for precision drilling.
Verify that the boring head, spindle, or adapter is intended for right-hand tooling and accepts the D108-series 10 mm shank configuration. Inspect the toolholder for contamination or damage, confirm low runout, and use drilling parameters appropriate to the workpiece and the 2 mm carbide diameter. Do not assume a cutting-length capacity from other D108 diameters; establish allowable drilling depth from the actual tool and machine setup.
Royce Ayr D108.020R combines a 2 mm brad-point cutting diameter, right-hand rotation, solid-carbide construction, and the D108 10 × 27 mm shank / 70 mm overall-length platform in a compact industrial dowel-drilling tool.
Correct rotation, concentric toolholding, controlled drilling depth, and stable workpiece support are central to repeatable results and service life when running small-diameter carbide tooling in production.
