Sometimes you may need to make a hole large diameter. The usual drill was not done, so that's made a this device.

Fly cutters are handy to have around

Trepanning is alive and well! Simple expedient for large holes in material of substantial thickness. Even thin material trepans, if clamped with a 'retainer' above. Sometimes the hole is not what you are after, it's the washer...Much like the difference between slug and blank in diework.
When possible, I trepan material thinner than depth of correct size drill point angle. It also compensates for insufficient machine size, or excessive RPM to spin correct size bit.
Works great in lathes too. Just prepare for a slug that temporarily has a mind of it's own.

Yeah a Saturday morning cartoon always comes to mind when that happens
Ping,ping ,piiiing Ricochet rabbit, and the razor sharp edge is like a chakram, it will slice through anything in its path unitl the kinetic energy dissipates
Did you drill a hole in the material first to allow for the center to go into? Looks like a handy tool, good job!
Hi Vyacheslav. Great idea, solid results. A maker's goal. It looks like shop material construction. Must be a carbide cutter I assume. How did you get the square hole in the round stock?
First you need to drill a central holeQuote:

My mortising machine don't do steel. If I wanted to make this tool how would I get a square hole to hold my square cutter in that round stock? Ignore this if I'm not making any sense. I'm a woodworker. I have three fly cutters. All have a square hole to hold the cutter. How do I make that hole?
no need to complicate the work, just round hole. Take this cutter structure, after clamping bolt it will be firmly fixed.

Got it. The best solution. Thanks.
