If you have not used a hole saw arbor before or you are still relatively new to these drill bits, you may have a few questions. Some of the questions often asked by Ruwag customers include the following.
Why do you need arbors?
As we briefly mentioned above, the primary purpose of an arbor is to keep your hole saw stable as you drill, without any shifts or movement of the teeth. If you are using a hole saw, you will need an arbor as well as a pilot bit to keep things steady. Arbors connect the hole saw to the drill chuck and the pilot bit. They help to take off the pressure often put on pilot bits and also help to create cleaner holes as the hole saw is fully secured.
What are the most common features of arbors?
There are a few features and accessories that will give your arbor even more performance. Some of the most common features include:
- Extensions - Longer arbor extensions will extend the reach of your hole saw to give you a deeper hole.
- Lock - Arbor locking devices will further stabilise your hole saw while you are drilling, keeping all bits in place.
- Quick change - You also get arbors that allow you to quickly change between hole saws for faster work.
- Correction - Some arbors are able to help you re-do holes that are less than perfect, expanding to a larger diameter.
Are arbors universal?
If choosing a premium brand such as Ruwag, you will have universal arbors that can be used with any brand of hole saw. With that said, you will need to choose the right size arbor to suit your saw.
Can you use a hole saw without arbor?
Technically, you can use a saw without an arbor, because these bits are pilot bits, however, it will be very difficult to keep the hole saw in place as you begin to drill. It is always best to use an arbor to get the best results.
Drilling any type of hole requires the right drill bits and adaptors, instead of just a single bit. Ruwag offers all the drill bits you need to get the best level of performance. Browse our full range to shop hole saw arbors and other premium drill bits online.
