Great Product
This is my first experience with self centering drill bits. I used the set a few times now and now I'm not sure how I made it without these for so long. Crazy effective and accurate, do yourself a favor and get some!

Woodworking Experience:
Great tool, easy to use - especially when installing drawer slides in cabinets.

Drops right into the metal predrilled hole on the slide and presents a hole nicely centered right where it needs to be.

I broke one of the drill bits, but was happy to discover that it was a breeze to replace.

How do I replace a broken bit in Rockler Insty Self Centering bits? I can see how to take it apart. Don't want to damage it. Thanks
Lonn L on Jun 4, 2017
BEST ANSWER: If I remember right, the centering barrel unscrews from the drive end of the centering bit assembly. The barrel is under spring tension so watch for the spring action when it is fully disengaged from the drive end. You should then be able to remove the drill bit and spring from inside.
I would like to get the soft case on its own with out the self cantering bits,is that possible?
Merlin S on Nov 14, 2015
BEST ANSWER: Not to my knowledge.
What size is in mm?
Woyas on Jun 29, 2016
BEST ANSWER: These are not available in metric.
I purchased hinges No. 28704.+
I already have a #5 self centering bit which I think is 7/64". will this size work?
A shopper on Aug 13, 2015
BEST ANSWER: The hinge set comes with #4 screws. I would try drilling a hole in a piece of scrap with the #5 bit and see how the screw fits
When you remove the end does the drill just pull out or is there a set screw that must be loosened?
Earl V on Jun 8, 2017
BEST ANSWER: I believe there is a small allen set screw that must be removed if you want to remove the drill bit from the mechanism. Also the forward spring mech can also be unthreaded and removed which helps getting the old bit out.
Are these made in the USA?
Tucki on Nov 5, 2016
BEST ANSWER: Yes sir, out of very few times you hear it but they are manufactured in the U.S.A, it is stamped on the housing that holds the bits
Dose this set come with a # 4 Bit& self centering Drive, if so I need to replace it. What part # do I use, or shod I by a complete set. Also how do I get replacement Bits?
Ralph A H on Dec 15, 2015
BEST ANSWER: Yes, the set comes with a #4 bit plus a #6 and #8. Personally, I'd get the whole set for $30 since they cost $13 for a single one. If your heart is set on just the #4 bit then look for Item #: 68984.
What size drill bit does each hold?
Eugene R on Feb 3, 2020
BEST ANSWER: The #4 is a 5/64" bit, #6 is a 3/32" and #8 is a 7/64" bit.
Does the case support the 4 drill bits or just this 3...?
Carlos Otto C on Feb 7, 2019
BEST ANSWER: The case has slots for five bits but it only came with three.
I find that my bits keep getting stuck with sleeve retracted, and I have to tug hard to get it to snap back. Is there some adjustment I can do to get them to spring back like they should?
Tom G on Aug 9, 2017
BEST ANSWER: check your drill bit and make sure they aren't bent. I have had mine get a slight bend and the sleeve doesn't reset.
What is more common, #4 or #10...?
Carlos Otto C on Feb 6, 2019
BEST ANSWER: For me it is the #4

Hope this helps
does this product have an adjustable depth stop?
Robert D on Apr 9, 2018
BEST ANSWER: It can be adjusted with the bit
are the drill bits mad in the u.s.a. also ?
mike on Oct 6, 2019
BEST ANSWER: The Country of Origin for this product is China.
How can I tell from looking at the individual self-centering drill bits which one is a # 8?
James D on Jun 14, 2018
BEST ANSWER: My set has three bits. Don't worry which size is which, just use the size that seems appropriate for the pilot hope that I need. Mostly use for drawer slides so use the smallest one.
How do I set the drill depth?
Vikki W on Apr 9, 2018
BEST ANSWER: You do not have to set the depth. The bits center the starter hole and the depth is just enough to get the screw started. They pretty much are automatic.
I have the set, I need the #10, what is the part number?
