Diamond Multi-Bore Tools

Diamond Multi‑Bore Tools from DK Holdings solve the common problems of drilling clean, precise holes in composite materials. Unlike standard HSS or tungsten carbide twist drills, these tools use diamond grains to grind rather than tear the material — ensuring accurate bores, reduced damage, and longer tool life.

These tools are offered in a variety of diamond grades to match different composites, from softer plastics to tougher fibre-reinforced composites. They can be manufactured to any custom size you require, making them highly versatile for production that demands tight tolerances or for oval/angled holes used in interconnecting tubes or pipes.

By switching to diamond‑grit Multi‑Bore Tools, you’ll experience significant improvements: holes that stay true to diameter, smoother edges, less wear, and fewer rejects. Delays caused by drill renewal or inaccurate bores are dramatically reduced.

We maintain common bore sizes in stock, but also support bespoke manufacturing for larger, unusual, or precision requirements. Our UK facility ensures quality control and quick turnarounds. Whether your work involves routing, trimming, or panel construction, these diamond tools integrate seamlessly into your workflow.

If you’re searching for reliable diamond‑grade tools or precision tools for composite hole boring, Diamond Multi‑Bore Tools from DK Holdings deliver performance, precision, and durability.
