Bi-Metal Plumber Utility Kit 5Pc

I've been using this line of utility bits for several years now and have found that they can handle any job. These bits have various advantages and disadvantages to a standard ship augers. One advantage is the three cutting blades. They allow for extremely fast boring through wall studs. The tool is hardened trough out, allowing it to chew through nails like they weren't even there. Unlike a ship auger, the blades can be sharpened. I use a small diamond wheel on my dremel tool to freshen up the edge about every 6 months. Nothing has been more unwieldy as an 18" ship auger to drill through single studs. Ship augers have a lot of steel making them expensive. I can't afford to have several different length augers in each size. This lenox bit is about 6" long but can use an extension shaft to get plenty of length. The only drawback I have found with this bit as opposed to a ship auger is its inability to evacuate the chips in a deep hole. Once I drill passed 4" the chips remain in the hole and begin to jam behind the bit. If I'm not careful the bit can get wedged in the hole.

These are really great - first they go through nail-embedded wood without any trouble (which is really important when running electrical wires in a remodel) and they also attach to a standard 1/4" hex shank, so you can use any number of extensions on them and keep going as long/deep as needed. If you are an electrician or even just occasionally run wires through studs you need this set if you don't already have it!They also seem quite durable, I really ran them hard on the last big project and they are fine - I imagine these will last a long time.

These bits are great and hold up quite well. Be aware the shanks are 3/8" and you will need that size when using extensions.

heavy duty bits work well

High quality drill bits. Self feeding. The only problem was that the bits tended to aggressively dig into the wood because of the self feeding feature. A plastic carrying case would have been nice.

I drilled a lot of holes with this bit set .I'm a electrician and HVAC contractor so lenox is a proven name when it comes to tools.

These bits work work great on my 18V cordless drill.

Top notch. Nice and ruggedly strong.

Excellent quality. Very pleasant to use. Bi-metal is a real plus.
