# 1. Using the drill
The Voltera V-One and V-One software are required to operate the drill.
### 1.1 Download the V-One software
{% content-ref url="/pages/GPt17y2hw3zba60cQBFS" %}
[Download the V-One Software](/docs/v-one/downloads/download-the-v-one-software.md)
{% endcontent-ref %}
### 1.2 Setting up the drill
1. Remove all items from the box. Make sure you keep all packaging in case the product needs to be transported in the future.
2. Connect the provided power cable to the C14 receptacle on the power supply, then to an earthed socket outlet.
3. Connect the female end of the 2.1 to 1.7 mm DC jack adapter to the 2.1 mm male DC barrel connector of the power supply.
4. Ensure V-One is powered and operating as described in the V-One manual.
5. When prompted by the software, mount the drill on V-One as instructed, and connect the male end of the adapter to the female barrel jack on the drill.
6. Ensure the two LEDs on the top of the drill are illuminated, and that the audible startup sequence has been completed.
### 1.3 Mount the sacrificial layer
The drill is supplied with a sacrificial layer: A large FR1 substrate with 2 slots on either side. It must be mounted directly on the printing platform to protect it from any damage during operation.
1. Mount the sacrificial layer on the printing platform.
2. Mount your substrate and secure it with the 10 mm long thumbscrews and clamps received with V-One.
### 1.4 Changing drill bits
To remove or insert a bit, use the provided 1.5 mm Allen key to loosen the set screw on the drill bit chuck.
* To remove a bit, pull gently on the drill bit until it slides free from the chuck. Inspect and store the bit appropriately.
* To insert a bit, gently slide the drill bit in the chuck until the straight shaft is no longer visible.
* Tighten the set screw with the Allen key.

### 1.5 Removing the drill
1. Confirm that all drilling has completed and the drill is stationary.
2. Unplug the DC adapter cable from the drill.
3. Remove the drill from V-One.
4. Remove any drill bits from the drill before storage.
### 1.6 Third-Party drill bits
The drill has been manufactured with very tight tolerances for high precision.
The use of unauthorized third party drill bits is not recommended as they may be manufactured with looser tolerances. Such drill bits may not fit in the chuck or may not be removed after insertion.

**Note:** Do not force drill bits in the chuck.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.voltera.io/docs/v-one/getting-started/v-one-drill-user-manual/1.-using-the-drill.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
