In short: the most suitable one is the best one.
However, for first-time users, identifying the "right" bit can be challenging—after all, true quality is proven through performance.
How Should a Beginner Choose a Diamond Core Bit?
The key lies in identifying your drilling material:
· Brick Walls: A standard diamond core bit is sufficient. Remember the principle: choose what is right, not what is expensive.
· Tiles, Artificial Boards, etc.: It is recommended to use a bit specially designed for tile or stone. For limited drilling tasks, a brazed diamond bit is an ideal choice.
· Concrete Floors: Please select an engineering bit or one specifically for concrete. If the concrete strength grade exceeds C40, the use of a cobalt-enhanced bit is recommended.
· Beams & Columns: Drilling should ideally be avoided, as these are critical load-bearing structures. If absolutely necessary, use a fixed drill machine (recommended speed ≤800 RPM) paired with a high-quality, high-cobalt bit.
Returning to the essentials, an excellent core bit must possess these five core traits:
1. Sharp & Efficient– It must not only "penetrate" but also drill "quickly."
2. Durable & Long-Lasting– It should complete at least one full hole or meet a full day's work demand without failure impacting progress.
3. Reasonably Priced– Time is money. For professionals, efficiency far outweighs a low price, as long as the cost is not excessive.
4. Reliable Brand– A reputable brand signifies more consistent quality and greater assurance.
5. Smooth Operation– The drilling process should be seamless and smooth, easy to handle, with wide applicability.
