About Neiko 10047A 12” Extra Long Drill Bit Set
Overall Feedback:
92% positive
90% appreciated its precise drilling accuracy, though 10% experienced deviation
I thought the drill bits are usually not good, but the 1/8th bit lasted for the whole project.
I have noticed that the countersink bits leave small burrs and uneven surfaces in the countersink holes, which negatively affects the accuracy of jobber-drill-bits.
89% praised for its fast drilling speed
These drill bits have long flutes, allowing me to drill well into the wood quickly while minimizing heat and friction.
86% liked its long-lasting durability, but 14% experienced frequent breakage
The jobber-drill-bits appear durable, but I haven't used them much yet.
I just started using the drill bits, so I'm not sure about their durability yet.
85% liked the comfortable grip design, while 15% found it slippery
With the right tools and technique, I can sharpen the countersink bits to a 5-star sharpness.
90% praised for its versatility in drilling various materials, though 10% had difficulty with metal
I found it worked very well in drilling through automobile floor pans to place small hangers for brake/fuel/speedometer cables.
I have only used these drill bits with wood and not with metal.
Using the screw extractor and left-hand drill-bit set has been easy and efficient for me in extracting bolts from vehicles. The drill bits and screw extractor grip onto stubborn bolts firmly, making removal a quick and efficient process without causing any damage to the surrounding components.
The drill bits have a 135-degree split-point tip design, ensuring accurate drilling and reduced walking, allowing for clean and precise holes in various materials.
I'm not sure what was going on with the 7/64th bit and later I broke the tip off another bit, so the hardness is really there.
