Dremel Rotozip XB-DW2 5/32-Inch Drywall X Bit, 2-Pack

Being a thicker bit helps it last much longer! Much better surface finish than other bits!!!Those complaining of durability probably have it set up wrong. With too much stickout from the collet you increase the chance of a break. With the bit not set deep enough through the drywall the pilot tip of the bit will be inside the drywall where it won't cut, and thus requires more force to push the tool leading to higher likelihood of a break.You want the pilot of the bit to be in the wall cavity not the drywall.Also to trace the outside of something like an outlet box try to go counterclockwise, to trace inside something go clockwise around it. This way the natural cutting forces are helping the bit stay in contact with the object.

This bit will really last along time, down side is it dulls just as fast as you guide points. I suggest keepimg this one on your corded router for windows and doors. Guide points on the cordless for boxes

Honestly, these things are tough! Ran into an issue at a job site overseas (that wasn't survey correctly...) where the exterior walls looked to be concrete in pictures, but turned out to be this weird stucco on tin with Styrofoam behind it and a strange thin metal mesh behind all of that material. Couldn't use the TapCons we grabbed for the "cinder" wall, and a drywall saw wasn't going to get through it easily enough, so I tried out this bit in the trusty Rotozip. Tore right through it! I was able to make Four 5x5 square cutouts through all that material before the bit finally wore down.Won't be buying any 5/32 bits if it isn't these!

Good nits for the money.

If you want to chop through drywall at high rates of speed and durability this is the bit for your saw

They work okay but some bits are fragile and some will last longer than others i wish they were built better took me 4 bits to do 3 cut outs in drywall and time wise almost 2 hrs had to go really slow no pressure or they break easily.

Homeowner/DIYer using while installing around 200 sheets of drywall. Have about 100 sheets hung and am still on my first bit. Was expecting to go through a few more based on some reviews. Works great!

These fit in my Rotozip perfectly. I was able to cut around 15 windows, a door and several electrical boxes during a drywall install and the first bit is still sharp

These bits are amazing everyone should have these bits for their drywall tool.
