(posted 2019-11-05 12:56:04.46) Hi, it is great that Thorlabs offers a lot of the special taps (metric & imperial) to allow the customer to do their own adapters. However I'm missing the M15.5 x 0.5 tap for the
SM15RR. Is it possible to purchase a M15.5 x 0.5 tap? Thanks! llamb
(posted 2019-11-06 09:49:47.0) Thank you for your feedback! Custom taps can be requested by clicking the red "Request Quote" button above or emailing techsupport@thorlabs.com. I have reached out to you directly in this case to discuss this possibility. Chris Betters
(posted 2019-04-08 04:44:40.833) Can you provide a tap for SMA threads (1/4-32)?
Thanks Chris YLohia
(posted 2019-04-09 03:13:43.0) Hello Chris, thank you for contacting Thorlabs. Custom taps can be requested by clicking the red "Request Quote" button above or emailing techsupport@thorlabs.com. We will reach out to discuss your requirements. ghovorka
(posted 2019-01-16 09:57:30.87) It would be very useful to have a tap for M10.5x0.5 threads. It is a great size for mounting 10mm OD optics with the SM10RR retaining ring, but can't be used as easily for custom mounts without a tap available. llamb
(posted 2019-01-17 12:02:50.0) Thank you for your feedback. I have added this idea into our internal product forum for further discussion. We can currently offer the M10.5 x 0.5 plug tap as a special item. I have reached out to you by email directly to discuss this special quote. kitchinsf
(posted 2018-10-24 16:12:02.7) It would be helpful to offer a tap guide for ensuring perpendicular taps to the work surface. Since the SM05, SM1, and SM2 are not very common outside of Thor, a tap guide that includes these (at least the SM05 and SM1, SM2 is a bit too large) it would be very helpful. The table tap guide is very useful but is limited in its functionality. llamb
(posted 2018-11-05 10:48:40.0) Thank you for your feedback. Tap guides like the TTT001(/M) typically need a flat reference plane like an optical table to fix to first. Most optomechanical parts with SM- threads are rounded or cylindrical, making it difficult to create a standardized tapping guide that fits to all components. We do not recommend hand-tapping these larger threads, but instead recommend using a type of drill press with a clutch for reversing the tap out of the threads. wenzel.jakob
(posted 2017-12-02 22:26:07.137) I'm also interested in a tap for SM2 threads. Could you please provide me with a quote? Thank you. tfrisch

I cannot find a tap for the SM2 threads. Would it be possible to get one?
Thanks, tfrisch

(posted 2017-03-15 08:46:56.48) What tapping depth can each tap achieve?! This is key info that needs to be added to this webpage. Also of interest are: overall length, shank diameter. tcampbell

(posted 2016-01-04 19:09:52.09) An 8/32 imperial tap would be very useful to complement the M4 metric tap. besembeson
(posted 2016-01-05 08:26:53.0) Response from Bweh at Thorlabs USA: We typically stock and provide mostly specialty taps that aren’t easily found as a convenience to those looking to integrate our components in their systems. As #8-32 is a very common thread, its tap can be easily found at local convenient stores or many other places online so we don't stock this. ghall
(posted 2015-11-24 11:50:45.943) What style of taps are those? For through holes or bottoming?
What class are they in terms of the tolerance/allowance?
Specifically looking at the M11x0.5 tap. besembeson

(posted 2014-01-13 14:58:47.927) What would you recommend for drilling out a broken-off cap screw? The stainless steel of the screw is quite hard, so I'm not sure what would have a decent chance of actually boring through it... jlow
(posted 2014-01-14 02:59:05.0) Response from Jeremy at Thorlabs: You can use a sharp carbide drill bit for this. You can use a sharp punch and a hammer to create a pilot first. The screw is susceptible to hardening, so once you begin the drill process, you should not stop until you are through the screw. Also, there should be a steady stream of some sort of cutting fluid on the drill bit so it does not get too hot. Your university machine shop or a local machine shop should have this cutting fluid readily available. user

(posted 2013-07-15 16:12:23.917) Worst drill bit set ever!. Tried to drill through copper 1/4" copper and was not able to because the drills are just dull. I would not sell these at all. cdaly
(posted 2013-07-18 10:15:00.0) Response from Chris at Thorlabs: Thank you for your feedback. It may be a matter of drill speed and feed. Please contact as at techsupport@thorlabs.com to discuss the conditions further. nejbauer

Do you have taps for imperial thread 8-32, which is very popular in your products?
Best regards,

Diagram of a Standard Tap
- Specialized Plug Taps
- Covers SM05, SM1, and Most Other Threads Used by Thorlabs
- Material: High-Speed Steel
These specialty taps aid in the integration of our optomechanical components into your custom-built devices. Our imperial taps selection includes many of the thread standards used by Thorlabs, including our SM05 (0.535"-40) and SM1 (1.035"-40) standards. Please see below for our metric taps.
Tapping Recommendations
To tap a hole, first machine a pilot bore, using the table below to find the recommended pilot bore diameter. The bore can be made using a drill bit or an end mill. For fine pitch threads, the pilot bore should be tightly toleranced because of the shallow thread depth; a reamer is also recommended in this case.
Next, secure the tap into a tap wrench, drill press, or lathe to create the threads. Lubricant or tapping fluid should be used to create the hole. If resistance is felt while tapping, carefully rotate the tap backwards to remove it, as broken taps are exceptionally difficult to remove.
If using these specialty taps for production, precision ring and plug gauges should be used to verify hole diameters. For additional details on threading and taps, please consult the Machinery's Handbook, available in many machine shops and bookstores.

Ratcheting Selector Knob and Sliding Crossbar
- Universal Ratcheting Tap Wrench with Sliding Crossbar
- Accommodates Taps from #0 to 1/4" or M2 to M6
- Shank Size from 0.141" to 0.255" or 3.6 mm to 6.5 mm
This machinist-quality Hand Tap Wrench is ideally suited for everyday tapping requirements. The rugged stainless steel design provides durability and long life, and the crossbar conveniently slides to provide extra torque when required. Ratcheting in either direction can be selected using the knob at the top of the wrench (see photo to the right). The Hand Tap Wrench can accommodate taps as small as #0 or 2 mm and as large as 1/4" or 6 mm.
ZoomRepairing a Damaged Tapped Hole

Once the TTT001(/M) guide is properly aligned over the hole, use the TW25 Hand Tap Wrench with a 1/4"-20 tap (Item # TAP1420) or an M6 tap (Item # TAPM610) to restore the threads.

To repair a hole with the TTT001(/M) guide, first secure it to the optical table using the included countersunk screws. These screws are designed to center the steel bushing over the damaged hole.

TTT001(/M) Tap Guide Dimensions
- Repair 1/4"-20 or M6 Holes in Optical Tables and Breadboards
- Bushings Help Ensure Tapped Holes are Perpendicular to the Work Surface
- Two 1/4"-20 or M6 Countersunk Mounting Screws Supplied
The TTT001(/M) Tap Guide is designed to assist in the re-drilling and re-tapping of an optical table or breadboard damaged by broken screws or cross threading. Two countersunk mounting screws (also known as flat head socket cap screws) are supplied for bolting the guide to the existing 1/4"-20- or M6-threaded hole matrix. A toughened, tool-grade steel bushing insert acts as a precise guide for drilling the broken screw out of the damaged hole. Another steel bushing guides the tap into the drilled-out hole, restoring the threads and ensuring that the resulting tapped hole is perpendicular to the work surface.
The main cause of tap breakage is unwanted sideways motion when the operator attempts to rotate the tap while simultaneously applying a force not purely parallel to the drill axis. This device discourages this costly error. We advise the use of a sharp, carbide-tipped drill bit to drill out the broken screw. When mounting the tap guide, care should be taken not to overtighten the countersunk mounting screws.
