Hopefully the answer is not just in the question itself, but what do I need to know about router bits to ensure they are safe for use with my router?

To clarify when I say "my" I don't Shank Router Collet 3d mean mine specifically. A router bit should have some information laser-engraved in its shank. Among these at the very least the shank diameter, maximum speed, and MAN or not. Some manufacturers Trend, notably have them written on the cardboard in the box, often in a "general" form such as 28,RPM up to 30mm, 24,RPM up to 30mm diameter, etc.

A bit that doesn't provide such information should go right into the trash can as it is not possible to operate it safely. Seeing how my life depends on that safe operation, that's a must for me. Shank diameter is not as obvious as you may believe. However, clamping the respective slightly-too-small shank in the slightly-too-large collet will result in the bit slipping and possibly come hurling through the room.

Clamping the respective slightly-too-large shank in the slightly-too-small collet will cause the collet to turn into shrapnels at an unpredictable time later. Neither one is a fun condition. MAN is important if you intend to use the bit in a plunge router. It means the bit has a certain maximum clearance behind the edge, so it will only bite at most so and so deep into the material with each turn.

That limits the amount of locking and kickback and determines whether it is reasonably safe to operate the tool manually MAN. Lacking the inscription MAN, you may only ever use it in a router table and forcibly controlled with a guide so the rotating bit won't kick the piece of wood out of your hands and into your genitals.

Regardless of whether a bit is "suitable" for manual operation, I consider diameters greater 20mm a "Meh, if I can't avoid" thing, and diameters greater 35mm a "Dude, you got death wish? Large bits become steadily more dangerous with increasing diameter, they belong in a router table. Bits with approx. But even if they did fit, I would think twice whether I'd want to use such a thing. Consider that centrifugal force as well as cutting speed goes up with diameter, so quite possibly your router cannot even turn slow enough to operate safely my router can just about rotate slow enough to satisfy 70mm, possibly 85mm profile cutters which usually allow 11, -- the ultra-large diameters often only allow 6,RPM.

Turning slower also means that your motor must be considerably stronger. If you have less than 2kW, you can pretty much forget running large bits at low speeds, it will be not a lot of fun. If a company sells a bit that is unsafe and you get hurt I am sure there's a few hundred lawyers that will take your case so you and them can retire.

Just my opinion but have never had a problem with one coming apart on both soft wood and hard wood. Have even used carbide bits to shape aluminum with welding gloves and a face mask. Sign up to join this community. The best answers are voted up and rise to the top.

Asked 5 years, 3 months ago. Active 5 years, 1 month ago. Viewed 1k times. Then looking at the link from this answer it brings other criteria to light: use of an inappropriate router bit in this case, a bit with wings too large for the shank use of a bit with a shank not long enough to be properly grasped in the collet not marking the tool with the maximum permissible speed not balancing the tool before use.

Improve this question. Matt Matt One would hope that the manufacturer tested the bits before shipping them to see if they're safe. Also, I have no idea how someone can look at a bit and say that the wings are too big for the shank.

Use the shortest flutes the job will allow when selecting an endmill. Same tool on lots of jobs. So, stickout is what it is and you need to move forward. Instead of grabbing the biggest collet chuck you have, grab the smallest one that can accomodate your endmill.

We can also try to orient the coolant nozzles to shoot down into the hole instead of bouncing off the toolholder. With the caveats of coolant access and flute length in place, the most obvious strategy is to minimize stickout for each tool and each particular job. One easy way to quickly get an idea of how much clearance each tool requires is to use our G-Wizard Editor.

As part of loading and simulating a program, it produces a tool table on the Tools tab that has the lowest Z coordinate used for each tool:. This is a new feature in GWE v1. This particular program is one of our stock sample Shank Router Collet Not Working files and it is an engraving program for a thin aluminum electronics panel. There are two tools, one with a minimum Z of Given that it is an engraving job, not much stickout is needed, so we can keep tools short. By using G-Wizard in this way, you can tell exactly how much stickout a given program needs.

But, no worries. First, G-Wizard lets you optimize multiple variables to fix a deflection warning:. Yup, you may not have to touch the tool Shank Router Collet Queue at all, just change one of the other parameters.

You can find the exact value needed by clicking the little speedo button next to the parameter arrows point to speedo buttons :. Is there any reason not to always use the minimal stickout for each job? Can any advantage be gained? This is a question of what sorts of jobs your shop runs and how you approach the problem of chatter. If, on the other hand, you do lots of different parts with short runs, setup time becomes your limiting factor as each new job requires a different setup.

You can get tired of unloading the toolchanger, resetting all the tool stickouts, and then reloading pretty fast. Chatter also complicates the question from two standpoints. First, if you use the same stickouts, chatter is a repeatable phenomenon. For more on all this, check out my article on chatter in the Feeds and Speeds Cookbook. Since changing the stickout will also change the chatter frequency, it is sometimes helpful to vary stickout to achieve a more optimal spindle rpm range when cutting.

These are relatively sophisticated considerations that seem very job-specific, so how can we come up with a strategy that helps a shop optimize its overall results? One answer is to standardize tool stickouts and choose several values for each tool diameter.

There are even tools available to help you standardize stickout lengths, such as Stop-Loc. Get our latest blog posts delivered straight to your email inbox once a week for free. Home Learn Blog. Back to Homepage. Shop All Our Products.
