Electroplated Diamond Dome‑Ended Routers & Composite Drill Tools

Electroplated Diamond Dome‑Ended Routers are advanced routing tools designed for trimming, rebating, and finishing composite surfaces such as GRP, FRP, and similar materials. At DK Holdings, these dome routers are engineered with a domed or rounded tip to smoothly contour or remove mould edges without gouging.

These electroplated diamond routers come in a variety of diameters (e.g. 4 mm, 6 mm, 8 mm) and configuration options such as standard tip or coated to shoulder styles. They are available in diamond grit grades 36/44 and 44/60 to match the demands of different materials and finishing needs. (As shown on current page: sizes, shank, grades) 

Because composites are abrasive and fibrous, these routers minimize edge damage and fibre pull. The domed profile ensures a controlled cut across curves, corners, and shaping tasks. Whether you are trimming moulded parts, finishing edges, or smoothing composite junctions, the dome‑ended shape offers smoother transitions than flat routers.

We keep a range of dome routers in stock for fast dispatch. In addition, DK Holdings offers custom manufacturing: specify a unique diameter, shank combination, length, or diamond grade that suits your equipment and application. All tools are manufactured under strict quality controls to ensure concentricity, coating integrity, and finishing consistency.

If you are looking for effective diamond routing tools, composite drill / router bits, or precision dome‑ended diamond routers for your GRP/FRP projects, DK Holdings has a solution.
