square drive centrotec bits
« on: October 21, 2011, 11:55 AM »
Just got a used drill. Now I know why the guy didn't like it :). He focused alot on the adapter allowing me to use all the bits he threw in with it, hehe.

Surely that can't be it, as Shane has pointed out that horse has been beaten to death time and again......  Beside, as I've said before I'm sure very, very few people would ever buy a square drive bit at $16 a pop if Festool offered them.

I say the next person that says they wants a Centrotec square drive bit gets this: [ban] [tongue] [big grin]

Go to Home Depot, they have Spax and I've been told they also have GRK screws too although I've not seen them in my local stores.

Don't worry you don't have to buy from the Depot, there are plenty of other retailers out there.

GF,

While I generally agree with you about HD, my local HD has a nice selection of Spax screws.   I think GRK are somewhat better, but they are very hard to come by around here.  To me, the whole square drive thing leaves me cold.    I use Spax with Torx, Posidrive, combo square/phillips heads whenever possible.   Torx is by far my favorite.   Can't be beat, IMO.   I use square drive screws only with my Kreg jig.

Regards,

Dan.

BTW, if people want a centrotec square drive bit, why not make one yourself by taking a BH 60 magnetic bitholder and glue a square bit in it? Use a cyanoacrylate based superglue and it won't ever come loose again so you have the same functionality as if it were one of the 100 mm golden centrotec bits.

GF,

I'm pretty sure you're aware of these options, but I wrote a post awhile back (with pics) about all the ways I've used different bits in my C12: http://festoolownersgroup.com/ask-festool/please-enlighten-me-re-festool-drills/msg100025/#msg100025

One thing I don't understand is the why there is an issue with using a square drive bit in a BHS65 (http://www.festoolusa.com/products/cordless-drills/centrotec-drill-bits/pilot-bit-with-depth-stop/centrotec-bit-holder-bhs-65mm-492648.html ).  This seems to be a hot issue with some folks, but I don't understand why.  Yes, I understand that it would be nicer to have a square drive CentroTec bit, but what's wrong with using the BHS65?

Dan.

Dan  although I understand the noise or need for this square drive, I have been using the BHS65 for a year now with my square drive bits and  have no issue at all. Sometimes ( I will get struck by lightening ) you just don't always have to use a Festool Bit to get thing done.

Dan, I can't help but think some (or maybe even most) people who argue for the Centrotec square drive bits don't know what they are asking for.  It's a square drive version of this 100mm one piece bit.

Personally I've never used one of these types of bit nor do I have any interest.  They are pricey at $18 (I think that's for two bits but I'm not sure).  I see little advantage to these bits for the extra cost.  Are they even magnetic?  With professional use driver bits ware out too quickly to spend $9 apiece on a bit.  I use the regular BHS or BH bit holder since I use so many different types and sizes of driver bits for my collection of screws.  It's far more convenient for me to have all the wire detent drivers bits I need right on the drill than a collection of one piece Centrotec bits.      

So here's a related question, how many of you guys use the Centrotec bits often and do you buy replacements regularly?

This is the freakin wish list forum and I made a wish.

Just because I'm not paying 18 bucks for a torx bit for screws that I don't have doesnt mean I wouldn't pay 18 bucks for a square drive bit.  Since when did price become an obstacle when talking about Festool's?

Again, it's more of a nag for me. I use the BH65 with wire detent robertsons daily. No real problem. If I need to use a longer ball detent bit, which is far less frequent I slap it on one of my keyless chucks, CXS or T-15, no real biggie. For square drive screws I use Robertson brand bits only, best fit and you get a lot of use out of them before they're no good. In fact i tend to lose them before they wear out. I can see the point of Festool brand bits being way over priced, I think the BH65 is way over priced and of lesser quality than what some competitors offer. I guess the annoyance was agitated with the release of the bit set at the start of the month, while the package of bradpoints and countersinks and all was great, the rest of those bits are pretty much useless to me. Yes I do use phillips and pozi drives doing installations when the film season is off, it's faaaar less frequent than my use of Robbies.

I would expect both the chuck and the Centrotec connection design to be separate patents. The Centrotec system is a design for how a bit would fit into a chuck and the specifications on the design of the bit connection. It's common to patent such designs. (For example, the iPod connector is patented.)

The question is, does Festool let other manufacturers make bits? So for instance, GhostFist likes the Robinson made bit. Would Festool allow them to make bits with Centrotec connectors?

I bought the various 100mm Centrotec bits and use them occassionally, modified some 100mm and 150mm Robertson bits to work with the Centrotec chuck and use those everyday. I use the BHS65 if I have to use Torx 10, Pozidrive or any other wire bit. Out of the Centrotec bits I use the #2 Phillips the most, mainly for disassembling or when replacing a Phillips screw for a Robertson. The main problem I find with the BHS65 Holder and wire bits comes when you have to sink screws below the bit depth,

Zapdafish, I think it is a good wish.  I too wish for a centrotec square drive bit. Nothing like a complete and uniform system. I have never had a bit holder that I really liked. Much prefer a one piece straight bit in the chuck.

Like many other things in the tool world it depends on how you work and personal preferance.

I would think that, as part of the entire centrotec system, this part of the bit would also be patented.



The question is, does Festool let other manufacturers make bits? So for instance, GhostFist likes the Robinson made bit. Would Festool allow them to make bits with Centrotec connectors?

In this thread Christian Oltzscher replied that they explored the posibilities.

"We have tried with numerous suppliers of bits to get a square drive bit in Centrotec format. We have tried on our own, and we enlisted the help of
McFeely's. It was not possible to get a Centrotec square drive bit in Festool quality at an acceptable price. We are well aware of the issue and we would love
to offer Centrotec square drive bits."

I see Jim (previous owner of McFeely's) is looking at the thread. I worked for McFeely's when they were approached by Festool about making a square drive Centrotec bit. We don't make it a habit of ignoring our customers.

As far as I know, there is nothing that would prevent another manufacturer from making such a bit.  But, I would suggest that any company thinking of doing so verify that rather than taking my word for it. While I try to be well versed in all things Festool, there's a lot to know. I admittedly don't know it all.

I was wondering if these cabinet screws from GRK would be good alternatives for the Kreg screws?  It seems as if the flat design of these screws mimic the head on Kreg screws.

The GRK Cabinet screw (washer head) is definetly too big for pocket holes. I have some. Great for other things though.

The GRK pan heads work very well in pocket holes.

I would expect both the chuck and the Centrotec connection design to be separate patents. The Centrotec system is a design for how a bit would fit into a chuck and the specifications on the design of the bit connection. It's common to patent such designs. (For example, the iPod connector is patented.)

The question is, does Festool let other manufacturers make bits? So for instance, GhostFist likes the Robinson made bit. Would Festool allow them to make bits with Centrotec connectors?

the problem is this... festool has copyrighted and trademarked all of their intellectual
property, and if they are like most companies, they patented the CEO's dog as well.

that being said, they my not want to bother with producing limited demand items like
square drive bits to fit directly into the centrotek, but if anyone else uses their
design, they have to go barking at them, or they risk losing the protection of the patent.

patent's, trade marks, and sales marks which are not defended can be weakened.

let's say someone on here makes for profit some bits we all want, and festool, not
wanting that market anyway, figures it keeps the customers happy, so why not?

next year, blork and dorkie decides to make a full range of bits that fit the centrotec,
and festool files for legal remedy.... and then it comes out in court that festool was
allowing someone else to use their intellectual property as if it was in the public domain.

me, if they were priced within reason, i'd love sets of fractional bits and unibits in
titanium dioxide, for drilling stainless.

so, i have bought some new unibits, and will go off and play with a lathe and toolpost
grinder, and put a centrotek shaft on those three or four bits, 'cause i'm stubborn.

festool could add square head tips without much inconvenience, seeing as lots of
people here would use them. i'd buy them in a heartbeat, as most electrical fittings
and panel screws, and circuit breakers use #2 square drive.

i don't think they are gonna do it, ever. so, we can either make bootlegs, or quit
whining about it.

These unrelenting posts about square drive bits has gotten out of hand.  I'm locking this and the other threads.  As soon as all of you come to your senses and accept nothing but slotted, I will then open these threads back up.

I need a bit that can drive screws which have the same type of heads that nails do -- just plain-old flat.

[laughing]


Has to work consistently though, so if anyone actually wastes his time trying to design one -- make sure you don't screw it up...

Have you used this brand of screw before?  How do they compare in terms of quality vs GRK?

A while back I bought 5 Lbs of each (shorter than 4"), at that time I couldn't find a source for GRK, and  I had come to love the torx head and still do. The common screws were fine  but the trim head screws seem to snap off driver bits for some reason. The face frame screws were fine as well, but my only issue with them was that I expected them to be cheaper (price wise) than the Kreg brand but they were the same price or a little more. I did not see any great advantage in the torx over the robertson head in this application. Since then, Home Dopey started selling their "deck" screws with a torx head and I started using them since it is so convinent to get them when ever you are low. Just yesterday I discovered that they were selling Spax torx head screws and I will start re-stocking with those. Also, Amazon is now stocking some sizes of GRKs, and their trim head screws can't be beat. Sorry to have rambled!
