## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA2075:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA2075:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

If you've started designing your own PCBs in [Eagle](https://core-electronics.com.au/catalog/product/view/sku/ADA1619) or [KiCad](https://core-electronics.com.au/kicad-skill-badge.html) and want to make your PCB a reality, you may end up with a CNC mill that can route out PCBs by cutting away the copper trace outlines. Adafruit initially ordered these end mills for Adafruit's use with an Othermill but they will likely work great in a wide variety of precision CNC machines.

While Adafruit already carry [PCB drill bits](https://www.adafruit.com/categories/329), end mills are slightly different. Drill bits can only cut in an axial direction, meaning in line with the axis of the bit - or up and down on the PCB. End mills can move in any direction so you can drill side to side, up and down, etc.

The cutting part is made from tungsten carbide and are suitable for circuit board cutting and probably some other soft metals and other materials. Each endmill has a high hardness, wear resistance and strength and they're also super sharp which helps when cutting thru PCBs. These mill bits have a fairly long flute, about 8mm. While this is a bit longer than Adafruit are used to, Adafruit have found that the bits work quite well and are low cost enough to replace if they break. Note that even carbide bits will dull eventually when cutting PCBs, Adafruit found Adafruit could cut for about 5 hours on each bit before Adafruit find they need replacing. This product comes with one 0.8mm carbide end mill in a protective plastic case.
