Custom Tooling for Windows & Doors
Bespoke Window & Door Tooling, Designed Around Your Profiles
From first sketch to CNC‑ground cutter, we turn unique geometries into production‑ready tools.
Why Custom Tooling?
Off‑the‑shelf knives rarely match heritage sash rebates or modern performance specs. Copenstick’s specialist division designs hyper‑personalised cutters and arbors, ensuring every joint mates perfectly and every gasket seats first time. That precision translates into faster setup, lower scrap and happier fitters.
Our Proven Four‑Step Process
| Stage | What happens | Your benefit |
|---|---|---|
| 1. Concept & Sketch | We review your section drawing or sample component. | Confidence we understand your goal. |
| 2. CAD & Feasibility | DXF profile generated, checked for clash and chip‑clearance. | Sign‑off before metal is cut. |
| 3. CNC Grinding | Tool steel or carbide blanks ground on 5‑axis CNC. | Micron‑level accuracy. |
| 4. Dispatch & On‑Site Testing | Cutters shipped within 7-9 weeks and proven on your machine. | Ready to run with zero rework. |
