NEIKO 10235B 13/16” Drill Bit for Metal, 1/2” Shank, Silver and Deming, 135° Split Point, High Speed Steel Drilling Bit for Metals, Wood, Plastics, Composite Materials

Nice and sharp, work really well. highly recommended to all my fellow wood workers.

I have a cordless, USB charged screwdriver with 1/4 hex head attachments that I keep in my desk drawer. I wanted to be able to drill pilot holes through thin materials (wood, 1/8" acrylic sheet) without going out to my garage and grabbing one of my larger drills and searching for drill bits (ADD roommate shares the tools in the garage and rarely puts the bits back in their slots).These bits worked wonderfully for my intended purpose. They securely fit into my cordless screwdriver and easily drilled through 1/8" acrylic sheet without cracking it. They also drilled into MDF easily. I've added these drill bits into the case that holds my cordless screwdriver and screw bits and I know this will save me a lot of time on my small projects in the future. It will also result in much less frustration with my roommate, at least in this regard. A definite win.

They seem to be well made and very sharp, they should do the job.

These are very good quality countersink, mine have had no issues with metal. They cut clean and smooth. I would recommend them and Amazon has an excellent price on them.

Works great ty

Not much to say other than these drill straight and quick. Not as many bits as some other sets but it has popular sizes. Comes in a little pouch which is a nice little feature.

Nice set, comes in a nice box to keep everything from getting lost

Nice looking countersinks. They are sharp and do well in wood and plastic material. Not so working with mild steel. Using them in drill press there is a lot of chatter and uneven cutting. You will not get a nice smooth bore.
