Do extra long drill bits come in metric and inch sizes?
admin2025-08-10T15:18:06+00:00Yes—available in both measurement systems depending on the application.
What’s the best speed for drilling with extra long bits?
admin2025-08-10T15:17:43+00:00Slower speeds for larger diameters and harder materials, higher speeds for small diameters in softer materials.
Can extra long drill bits be resharpened?
admin2025-08-10T15:17:19+00:00Yes—if they are HSS or cobalt. Carbide-tipped versions may require professional sharpening.
What is the difference between an aircraft extension bit and a jobber length bit?
admin2025-08-10T15:16:50+00:00Aircraft extension bits are much longer and designed for deep or hard-to-reach drilling, while jobber bits are standard length for general drilling.
How do you store extra long drill bits?
admin2025-08-10T15:16:01+00:00Use protective sleeves, racks, or cases to prevent bending and tip damage.
Do extra long drill bits break easily?
admin2025-08-10T15:15:38+00:00They can if misused—avoid side pressure, excessive speed, or forcing the cut.
How do you prevent an extra long drill bit from wandering?
admin2025-08-10T15:15:02+00:00Start with a short pilot hole using a standard-length bit, then switch to the extra long bit for full depth.
Can you use extra long drill bits in a hand drill?

Can extra long drill bits drill metal?
admin2025-08-10T15:13:35+00:00Yes—use cobalt or carbide-tipped versions for hard metals like stainless steel, and apply lubrication.
What materials are extra long drill bits made from?
admin2025-08-10T15:12:53+00:00Typically high-speed steel (HSS) for general use, cobalt for hard metals, and carbide-tipped for masonry or abrasive materials.
What are extra long drill bits?
admin2025-08-10T15:06:59+00:00Drill bits with an extended flute and shank length designed to reach deep or hard-to-access areas while maintaining hole accuracy.

What do you call a long drill bit?
admin2025-08-09T16:33:48+00:00They’re often called “extra long drill bits” or “jobber-length,” “ship auger,” or “aircraft extension” bits depending on the design and purpose.
Is there a drill bit extender?
admin2025-08-09T16:32:34+00:00Yes. Drill bit extenders hold the bit securely and add extra reach—great for tight spots or deep holes.
How to extend the length of a drill bit?
