💧 How to Keep Your Bit Cool

To avoid premature wear, always use water during drilling:

• Build a mini water dam with plumber’s putty
• Use a spray bottle to mist the bit
• Run gentle water flow over the drilling area

🎯 Easy Targeting Without a Pilot Bit

Keep your drill bit steady with these simple techniques:

• Use a DIY guide made from plywood, plastic, or cardboard
• Start drilling at an angle, then gradually move to vertical
• Hold the bit in place with a wet sponge until it bites

⚠️ Safety First

Always wear protective gear when drilling. Safety glasses, gloves, and a dust mask are recommended.
