How to Drill a Hole in A Ceramic Bowl: Drilling the Hole

Step 1: Starting the Drill Slowly

Begin the drilling process by carefully positioning the drill bit directly over the marked spot on the ceramic bowl. Press the trigger on the drill using gentle pressure drilling to start at a low speed. It is important to allow the drill to work at its own pace, relying on the bit’s natural cutting ability rather than applying excessive force. This gentle approach reduces the risk of damaging the ceramic and ensures a clean entry point.

Step 2: Maintaining the Right Angle

To achieve a perfect, straight hole, maintain the drill at a consistent 90-degree angle relative to the surface of the bowl. This alignment is crucial to prevent tilting, which can lead to uneven holes or the risk of cracking. If the drill is tilted, it may cause unnecessary stress on the ceramic, potentially undermining your hard work.

Step 3: Applying Water to the Drill Bit and Bowl

Regular lubrication is key to a successful drilling operation. Use a spray bottle filled with water or keep a damp sponge close by to periodically moisten both the drill bit and the drilling area. Consistently applying water helps lower friction, prevent overheating, and ensure smooth operation. This cooling method not only protects the ceramic surface but also extends the lifespan of the drill bit by keeping it within optimal temperature ranges.
