The Bottom Line
If you've ever damaged an auger bit by hitting a hidden nail in the wood you're drilling, you'll appreciate the Bosch NailKiller drill bits. These Bosch NailKiller auger bits are designed to chew through any nails hidden in the wood that you're drilling, rather than having the nail cause damage to the bit. Bosch claims that independent testing has shown that these bits can handle as much as nine times more nail hits than conventional auger bits. While they are typically a bit more expensive than traditional auger bits, the extra longevity will likely make them a good value.
Pros
- A safer investment than traditional auger bits, as they won't get chewed up if you catch a nail
- Drills clean holes for an auger bit
- Pushes most nails out of their holes for easy removal
Cons
- A bit pricier than conventional auger bits
Description
- Available in a variety of sizes (1/4" to 1-1/2" diameter and 7-1/2" to 24" in length).
- Has a dual-reamer-edge design also available on Bosch Daredevil Spade Bits.
- The NailKiller delivers considerably less feedback force to the user than typical auger bits when hitting a nail.
Guide Review - Woodworking Review of Bosch NailKiller Drill Bits
The Bosch NailKiller auger bit is a departure from conventional bits, in that the bit is designed specifically to handle repeated hits from hidden nails when drilling. While a conventional auger bit can get chewed up and destroyed by a nail in the wood being drilled, the NailKiller is designed to not only chew through the nail, but in most cases, will actually push the nail out of the nail hole, making the nail easy to remove.
The other advantage of the design of the NailKiller is that when a nail is hit while drilling, the feedback to the operator is considerably reduced. When hitting a nail with many conventional bits, the drill tends to grab and twist, which is an easy way for the user to sprain a wrist. With the reduced feedback, this wrenching is far less likely to occur should a nail be struck.
