📋 目次
1What's the difference between high-speed steel and cobalt drill blanks?
High-speed steel (HSS) blanks are affordable and work well for general drilling in wood and soft metals, while cobalt blanks cost more but stay sharper longer and handle harder materials like stainless steel better. Choose HSS for casual DIY work and cobalt if you're drilling frequently or tackling tougher materials.
2How do I know which diameter and length drill blank I need?
Match the blank size to your project — measure the hole you need to drill, then pick the corresponding diameter. Length matters too: longer blanks reach deeper holes, but shorter ones are more rigid and less likely to wobble or break on tough jobs.
3Should I buy pre-sharpened blanks or sharpen them myself?
Pre-sharpened blanks save time and work right away, so they're worth it unless you have sharpening equipment and experience. If you drill regularly, learning to sharpen can save money over time, but the learning curve is steep.
4What's the benefit of titanium-coated drill blanks over plain ones?
Titanium coating reduces friction, keeps bits cooler, and extends lifespan — especially useful if you drill through multiple materials in one session. Plain blanks are cheaper and fine for occasional use, but coated ones deliver better value if you drill regularly.
5Do I need different blanks for drilling wood versus metal?
You can use the same drill blank for both, but the cutting angle differs slightly — wood bits are more aggressive, while metal bits have sharper, shallower angles. For best results with each material, consider getting separate sets; for general work, a universal blank works acceptably in both.
