Drill Bits FAQ Section
What materials can your drill bits work with?
Our drill bits are designed to handle various materials including wood, metal, plastic, and masonry. The DB-100 series works best with wood and plastic, while the DB-200 cobalt series is ideal for metal applications. For masonry work, we recommend our DB-300 titanium-coated series.
How do I know which drill bit size to choose?
The size of drill bit you need depends on your specific application. For precise hole sizing, always check the requirements of your project. Our drill bits come in both imperial and metric measurements. When in doubt, start with a smaller bit and gradually increase size until you reach the desired hole diameter.
What maintenance do drill bits require?
Proper maintenance extends the life of your drill bits. Always clean them after use to remove debris. Store them in a dry place to prevent rust. For metal-cutting bits, occasional lubrication helps maintain performance. Regularly inspect cutting edges for wear and replace when dull.

More Drill Bits FAQs
What's the difference between 118° and 135° point angles?
The 118° point angle is more versatile for general-purpose drilling in softer materials like wood and plastic. The 135° angle provides better performance in harder materials like metal, as the sharper angle helps the bit bite into the material more effectively while reducing walking.
Can I use the same drill bit for wood and metal?
While some general-purpose drill bits can handle both materials, we recommend using specialized bits for optimal results. Metal requires bits with different geometry and often harder materials like cobalt steel. Using wood bits on metal can cause excessive wear and poor performance.
How often should I replace my drill bits?
Replace drill bits when you notice decreased performance, excessive heat generation, or visible wear on cutting edges. With proper use and maintenance, HSS bits typically last for dozens of holes in metal or hundreds in wood. Heavy-use professionals might replace bits monthly, while occasional users might keep them for years.
Safety Tips When Using Drill Bits
- Always wear safety glasses to protect from flying debris
- Secure your workpiece properly before drilling
- Use appropriate speed settings for your material
- Apply steady pressure - let the bit do the work
- Allow bits to cool between extended use periods
Final Drill Bits FAQ Section
What causes drill bits to break?
Drill bits typically break due to excessive force, improper alignment, or dull edges. Other causes include using the wrong speed setting, drilling at an angle, or attempting to remove the bit while still spinning. Always ensure your bits are sharp and use appropriate technique for your material.
How can I drill through hardened steel?
For hardened steel, you'll need cobalt or carbide-tipped drill bits. Use cutting fluid to reduce heat, maintain low RPMs with high pressure, and frequently clear metal shavings. Start with a smaller pilot hole before sizing up to your desired diameter.
What's the best way to store drill bits?
Organize drill bits in a dedicated case or rack that keeps them separated and protected. For long-term storage, apply a light coating of oil to prevent rust. Store in a dry environment and avoid dropping bits or allowing them to knock against each other, which can damage cutting edges.
Investing in quality drill bits pays dividends through cleaner cuts, faster work, and less frequent replacements. Our comprehensive selection ensures you'll find the perfect bit for any application, backed by engineering excellence and rigorous quality control.
