FAQ's: Extra Long Drill Bits

Yes—available in both measurement systems depending on the application.

Slower speeds for larger diameters and harder materials, higher speeds for small diameters in softer materials.

Yes—if they are HSS or cobalt. Carbide-tipped versions may require professional sharpening.

Aircraft extension bits are much longer and designed for deep or hard-to-reach drilling, while jobber bits are standard length for general drilling.

Use protective sleeves, racks, or cases to prevent bending and tip damage.

They can if misused—avoid side pressure, excessive speed, or forcing the cut.

Start with a short pilot hole using a standard-length bit, then switch to the extra long bit for full depth.

Yes, but longer bits flex more—keep speeds moderate and apply steady, even pressure.

Yes—use cobalt or carbide-tipped versions for hard metals like stainless steel, and apply lubrication.

Typically high-speed steel (HSS) for general use, cobalt for hard metals, and carbide-tipped for masonry or abrasive materials.

Commonly available from 6 inches, 8 inches, 9 inches, 10 inches, 12 inches, 15 inches, 18 inches, 24 inches, 36 inches, 48 inches, 60 inches & 72 inches with “aircraft extension” bits even longer.

Drill bits with an extended flute and shank length designed to reach deep or hard-to-access areas while maintaining hole accuracy.

Long bits are used to drill through thick materials, reach into tight or recessed areas, or pass through multiple layers in one go.

They’re often called “extra long drill bits” or “jobber-length,” “ship auger,” or “aircraft extension” bits depending on the design and purpose.

Yes. Drill bit extenders hold the bit securely and add extra reach—great for tight spots or deep holes.

You can use a drill bit extender or flexible shaft attachment to add reach without buying a new bit length.

Yes. Extra long bits are available in various types—twist, auger, spade, and ship auger—ranging from 6 inches up to 48 inches or more.

Not always. Longer bits reach deeper spots, but they can flex more and may be harder to control. Use the shortest bit that still gets the job done.
