Through vs. Stopped 5mm bit

[ear3]

Just picked up an LR32 set -- not the systainer version but the one w/plate and stops.

Quick question about the 5mm bits--one is for stopped holes (491066) and the other for through (491064) holes.  I got the former, assuming that it wouldn't be a problem to use it for the through holes when needed.  Is my assumption correct?  And what exactly are the advantages of the one specifically designed for through holes?  Is it just that the spear point produces less tearout at the end of the hole?

The problem is that the stopped 5mm bit caused massive tear-out trying to drill a through hole.

If you need to do this in an emergency, be sure there is a solid sacrificial board in firm contact with the back side.

By the way, the through bit does not produce a flat bottom hole, so even in 19mm sheet material if you try making the hole deep enough conventional 5mm pins seat correctly, you will break through the other side slightly.

Probably these are reasons Festool sell the separate bits for different purposes.

My firm specializes in high-end custom cabinets, but we also produce a lot of closet organizers, which typically use a lot of through holes. Of course we stock both style bits.

To get maximum life from those bits we always reduce the speed of the OF1010. We have not found that the quality of the holes improves with an increase of speed.

Got it.  Thanks.

Hi Peter,

I sure wish I could contribute more to FOG.

My right hand has not worked correctly since last mid-December. About the only Festool I can still use is the TS55 on rip cuts, which I always did left handed! Typing is also a challenge since I started touch-typing as a young child. I've had to learn to hunt and peck.

We all know I am passionate about System 32 and all things LR32.

Oh, yes, another tip: forget the speed chart about 20mm and 35mm hinge bits. You are boring shallow holes, not drilling or routing. Slowing the router to minimum will not decrease hinge hole quality or reduce productivity, in my experience. As with the 5mm bits, turn them slower and they produce more holes per sharpening.

Yes indeed, the 5mm, 20mm and 35mm bits can be sharpened. If a grinder cannot sharpen them, find another grinder.

Yes, CCarol, nice to see a post from you. I was beginning to worry because I could not recall seeing one from you for quite a while. Sorry to hear your hand is giving you trouble but happy to hear you are still at it.

I to have been have to deal with a similar issue for many years and now I'm having to get it repair,  bad genes and bad luck on my account.  I just wanted to say that I feel for you and hope you can get back at it soon.

[member=8251]ccarrolladams[/member] glad to see you back. Sorry for your health issues.

I don't have any direct experience with what's out there, but  have you taken a look at any of the speech to text offerings? I know some folks that rate them highly.

Thanks for the kind thoughts.

Actually several years ago when I had no trouble touch-typing, I invested in Dragon Natural Speaking Professional with the Medical and Legal Options. This is the most popular voice recognition/transcription software with the Hollywood writing community. At the same time I bought a Phillips model 9360 hand-held digital dictation recorder. Its charger is connected to one of my computers so when I put it on charge it downloads the most recent dictation and then transcribes that in background so that I can use that computer for other functions while the transcribing is happening.

My Natural Speaking also works very well with Final Draft Pro, the script formatting software virtually all of us in Hollywood use.

The thing is for short things such as e-mail and posts, even using H&P I prefer to type. I do like Natural Speaking when writing dialog so I can move around acting out the various characters.

Every time I use Natural Speaking, as I correct the raw transcription it gets more accurate recognizing my voice, even when I am performing in character, so after all these years it does not require a lot of correction.

My memory is that when I bought that system the whole thing including the hand-held recorder was about the price of a TS55 with a CT22 and a 3000mm rail. Trust me, like my Festools, that VR equipment and software has made me good money.
