Common Drill Bit Problems and How to Fix Them

Even with high-quality drill bits, problems can occur during use. Here are some of the most frequent issues and how to resolve them:

Problem 1: Dull Cutting Edge

• Cause: Excessive use or overheating.
• Solution: Sharpen the bit with a grinding tool or sharpening jig. Use slower speeds and lubrication when drilling hard materials.

Problem 2: Bit Breaks Easily

• Cause: Using the wrong bit type or applying too much pressure.
• Solution: Match the bit to the material and let the tool do the work. Keep the drill aligned straight and avoid side pressure.

Problem 3: Bit Wanders at Start

• Cause: Lack of pilot hole or uncentered tip.
• Solution: Use a center punch to mark the drilling point or start with a smaller pilot hole.

Problem 4: Overheating and Smoke

• Cause: Drilling at high speed or without coolant.
• Solution: Lower drill speed, use cutting oil or water, and apply less pressure.

Problem 5: Bit Stuck in Material

• Cause: Flute clogging or drilling too deep without clearing.
• Solution: Clear debris frequently, back out the bit occasionally, and avoid forcing it.

Tip: Always monitor bit condition during use. Replace bits that are worn, chipped, or bent to avoid damaging your workpiece or drill.
