FAQs

What is the best speed to use this drill bit?

It is best to use this drill bit at a slow speed, typically between 200-300 RPM, especially when drilling into glass or porcelain to prevent overheating and chipping.

Can I use this bit for drilling metal?

No, this drill bit is specifically designed for glass, tiles, and porcelain. It is not suitable for drilling metal.

How do I keep the bit cool?

You can keep the bit cool by applying a small amount of water or a specialized cutting lubricant to the drilling area. A slow speed also helps manage heat.

What kind of drill is required?

This bit is compatible with standard corded and cordless drills equipped with a 3-jaw chuck. A variable speed drill is recommended for optimal control.

How do I prevent chipping when drilling glass?

Start at a very slow speed to create a shallow mark, use steady, light pressure, and ensure adequate cooling. Securing the glass and using a drilling template can also help.

What is the shank type?

This bit features a flute-less straight shank, designed for a secure grip in standard drill chucks.

Troubleshooting

Drill bit is not cutting effectively.

Ensure the drill is set to a low RPM. Increase pressure slightly, or check if the bit tip is worn. For glass and tile, ensure adequate cooling with water or lubricant.

Bit is overheating.

Immediately stop drilling and allow the bit to cool. Reduce drilling speed and apply more cooling lubricant (water or specialized cutting fluid).

Material (glass/tile) is chipping excessively.

Start drilling at a very slow speed to create a small indentation before drilling through. Apply lighter pressure and ensure the material is stable. Check if the bit tip is damaged.

Bit wanders on initial contact.

Use a center punch or a piece of tape to create a starting point. Start drilling at an extremely slow speed until a small divot is formed, then proceed normally.
