I have several of the Colt 5 Star Parabolic bits and LOVE them. I was wanting to add to my collection with a 10.5 and 12.5 mm. I looked via Google and no luck. Went to the Colt site, www.colt-tools.com and searched there vendor list no dice. So I submitted the question to colt. Any ideas on where to purchase these bits? Thanks.

Doug:
I don't think colt makes a 12.5 or 10.5 parabolyic bit, or at least don't make them available in the USA.

If I am wrong , please let me know as they are JR and Triton sized and a "must have" in my shop. I have looked for them for a while , without success.

Good luck! Keep me posted.

Andy,

Colt makes them. Part #10151050 = 10.5mm. Part #10151250 = 12.5mm. Directly off there web site. But as you correctly pointed out no one carries them.

Doug if you find a place to buy the Colt 5 Star PEN Parabolic 10.5 and 12.5 mm bits let me know, I'm in for both. It is time consuming drilling with a under size Colt 5 Pen bit then going in with a 10.5 and then a 12.5 for the other barrel.

Do they make any parabolic bits that aren't so long? The Colt 7mm I have is nearly twice as long as neccessary IMO! I would prefer a normal lenth, although I DO like how they work!

First off, please correct me if I am wrong about any of this; I'm no expert, just a satisfied consumer of Colt Five Star parabolic drills. Germany's Horst Miebach manufacturers two grades of "Colt" brand drills: Colt Twinland (which are NOT the highly regarded parabolic drills) and Colt Five Star (or 5-Star). The Colt Five Star drills are available in two length classes: "jobber length" in conventional inch and metric sizes, and a few inch, metric and letter sizes also are made in the longer "pen" length which are distinguished as Colt Five Star Pen drills. The key identifiers are "Five Star" (or "5-Star") for the parabolics, and "Pen" if you want the longer parabolic drills. I have found the best in-stock inventories at The Best Things ( Jobber Length: http://thebestthings.com/newtools/miebach_drill_bits.htm ), (Pen Length: http://thebestthings.com/newtools/miebach_pen_bits.htm), and at Traditional Woodworker (Both Jobber & Pen Length: http://www.traditionalwoodworker.com/ Hint: Search for " 5-star ").

Do they make any parabolic bits that aren't so long? The Colt 7mm I have is nearly twice as long as neccessary IMO! I would prefer a normal lenth, although I DO like how they work!

Lenny, look here for "regular" length Colt Five Star 7mm drills :

Hut Products publishes several very valuable (IMHO) charts in their printed catalog and online ( http://www.hutproducts.com/products.asp?dept=165 ), one of which is their "Decimal Equivalents Chart" which compares Inch, Decimal, Letter, and Metric dimensions. Per the chart:
13/32 in = 0.4062)
10.5 mm = 0.4134
27/64 in = 0.4219

Stick Rounder, Colt 5-Star Pen Drills are available in both 13/32" and 27/64". Keeping in mind run out and other tolerances in your drill press, lathe, bushings, etc. would either of these work for you?

I ordered Colt 10.5mm & 12.5 mm bits from here

Go to www.fine-tools.com and they have both bits and they ship to the US. The price including shipping was not bad - near the normal price that you would pay for 2 colt bits at WC or Rockler.

Lenny,I also was looking for a shorter version of the PEN parabolic bit.I ordered 5 of the 5 STAR short bits from The Best Things.The description sounded like they were the same as the pen drills,however they came today and the cutting tip is more brad style than the parabolic tip that I wanted.They look like good bits so I will give them a try,but not what I wanted.

Thank you for that. I had the same problem..needed 10.5, 11 and 12.5mm colt pen drill bits. Couldn't find them anywhere and received no replies from Colt as to where I could buy them.

I ended up odering the three sizes and the shipping to Canada was not out of line. 7euros.

Thanks again.

Cheers,

Peter
