How to use a hole saw from tungsten carbide hole saws Supplier?
1. First make sure you are using the correct and effective hole saw drill to cut the hole.
Cordless cutting drills work better on thin, soft metal surfaces, although you'll need at least a 14V drill for cutting.

Never attempt to drill with a rechargeable or battery powered drill on brick walls or hard surfaces (anywhere above 50mm).

2. Always equip yourself with adequate PPE protective clothing before using the hole saw.
This should always include suitable goggles or glasses, a dust mask suitable for the material being cut, and at least good quality work gloves.

Never wear loose clothing that could get caught in the hole saw, such as loose sleeves or hanging jewelry, and always keep long hair tightly behind your head.

3. Regardless of the material or surface you are machining, do not attempt to push the drill in faster than desired.
The standard way to get a neat and perfectly round hole is to use gentle and constant pressure.

Start at a slow speed and slowly increase the rotation speed.

4. The main important issue in hole depth, in addition to the rated power of the hole saw drill, is always the basic design of the hole saw, especially the way it works with its design and material discharge.
Often, scraps of material build up inside the hollow center of the hole saw, eventually blocking and preventing it from falling after a certain depth.

At this point, the user may need to use a screwdriver or related poking tool to remove the waste material.

In many cases, this can be achieved with realistic "speed grooves" that many brands have cut into the sidewalls of their hole knives for this purpose.

To that end, more advanced designs may feature an ejection spring, usually wrapped around a central mandrel, if available.
