When people ask me how to drill a square hole in metal I will now tell them. All I knew about was mortisers for wood. And to think I used to bribe out holes in metal, drill in each corner and then use a file after drilling a larger hole second. Brilliant !

no, watts brothers floating chuck

The things are the bane of my existence. I’ve used them hundreds of times to put a “drive hole” into the end of a hardened worm gear. We buy the gears set worm & rings and modify them. I’d love to perform the op in an annealed state but it’s not feasible. The end is about 45 Rockwell hardness. We insert the worm into a fixture that has a guide plate over the end. The pilot hole size is critical to make the drill work hard enough to get into the corners. Alignment and squareness of the head, adequate thrust, feed, speed and flood coolant are imperative. The Watts drill typically lasts one to three parts before resharpening. The drill takes two months to obtain or factory resharpen so we do it in house much of the time. Once you start the operation you have very little control over size, taper and corner sharpness so you cross your fingers and pray. Whenever I can I try to use a rotary broach instead but sometimes it’s just not doable because of the extreme thrust that op requires exceeds capacity of my equipment on large holes.

Thanks for sharing Karl, I'll bet it help with productivity at your place of work.

Hi Eddie thanks for your question, you are correct. The square size is dictated by the square so a 10mm requires a 10mm square die. The trick is the "floating" cutting tool needs one less cutting edge than the shape it is producing, in this case three cutting edges for four corners (square). If you Google "rotary broaching" you will find lots of examples. Thanks for your post.

So how was the first square hole created before you had a square hole to create the square hole.

There are many ways to create a square hole, wire or spark erosion for instance

Sorry for the slow reply. Great question, the cutting action is on the end of the drill and there is a starting hole so as long as the material to be cut isn't harder than the drill it shouldn't damage the drill. The drill floats on the x-y axis, the trick to the sharp corners is having on less cutting edges on the drill than corners required. Thanks for posting. Google rotary broaching.

This looks like magic. Even though I watched an animation of how it works before I watched this video, my mind still couldn't comprehend how something spinning could drill a square hole.

Two things are happening, the drill has one less cutting edge than corners which forces it into the corners and the drive end is a floating eccentric.

Yes, the drill is mounted on a morse taper so it will fit in the tailstock of most lathes. You would need to adapt the die to your headstock/chuck.

They are fairly small, about 1/32". Thanks for your question.

The short answer is it depends on how hard the material is, like any drill the harder the material being cut the shorter the time between sharpening. the pilot or guide is hardened steel. The setup in the video has been around and in use for years. Thanks for your question.

This tool in this video is a Watts Drill Bit and floating chuck, using reuleaux triangle method, made by Watts Brothers Tool Works out of Wilmerding Pennsylvania. They do not have a web site nor a online brochure or catalog that i can find. If you would like contact them you must google the company name. Good luck!

I want a rotary broaching head so bad. It would be so nice to put my own larger torx drives in the plain headed pivots I use. Awesome jig too!

Great vid, thanks for posting! This is a nice tool! It will cut blind holes, a situation in which broaching is difficult at best! The pilot is hardened tool steel and the triangular drill is very likely high speed steel. The cutting edges of the drill contact the surfaces of the pilot during use. How fast does wear occur?

Now all i need is a nice square hole to start drilling a square hole

The Watts Bros. tools were invented by Harry Watts in Turtle Creek Pa. U.S.A approximately 110 years ago.

This is a Reuleaux triangle. The only shape other than a circle that cannot fit through its own hole! Sandwiched between 2 plates it will roll completely smoothly, just like a circle. Quite amazing. Remember the Wankel rotary engine in the old Mazda RX-8? Yep, the 'piston' was a Reuleaux triangle. Make a manhole cover out of a Reuleaux triangle and it can't fall through its hole either! And you can use them to drill square holes. Or any even sided polygon hole. Quite amazing. The drill bit to do this was patented a century ago.

By using a cutting tool with one less cutting edge than the sides of a triangle (two cutting edges) an triangle shape can be made. You would need a triangle shaped guide. It can also be done by hand.
