Best Extra Long Drill Bits of 2025

"I used this 8-inch long 1/8-inch bit for pre-drilling holes in cedar fence boards. It easily drilled through 8-10 boards at a time, which is a huge advantage over shorter bits. I was impressed by its durability and how well it handled knots without much effort. I had to start it gently to avoid bending, but once I did, it drilled straight through. This bit really saved me time."

"This Bosch drill bit is of fantastic quality. At 1/8th" thick, it’s very rigid. I can drill guitar wiring routes with confidence knowing the bit won’t deviate. I’m building a guitar workshop and reviewing everything to help other D.I.Y builders like me make informed choices."

"This worked perfectly for drilling reference holes from the back before cutting drywall. I had to handle it carefully because it's very thin, but that's the point!"

"These drill bits are good quality and affordable. I did break one due to my own mistake, but I was using too much force while cutting steel. I managed to sharpen it, and it still cuts fine. Just remember, bits this size need to be run at a lower speed with minimal pressure to avoid breaking."

“I've used these bits several times, and they drill through 1/2 steel with no problem; just go slow and easy.”

“I bought these bits to pre-drill some fence posts, but they are really dull. I clear the cuttings regularly, but they just don’t want to cut. I'm really disappointed and wish I could return them.”

"I've been using these to pre-drill for lags in wood posts and fence runners. They have performed flawlessly after hundreds of holes, showing no signs of wear. I had to grind the cutting edge back into shape a few times, which is expected. Overall, these bits meet my expectations and are worth the price."
