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?
admin2025-08-10T15:14:23+00:00Yes, but longer bits flex more—keep speeds moderate and apply steady, even pressure.
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?
