  • For fine pitch threads, it is especially important to tightly tolerance the pilot bore because of the shallow thread depth.
  • Item numbers with drill sizes listed have a pilot bore diameter equal to a standard drill size to within ±0.001". For item numbers without a corresponding standard drill size, please refer solely to the pilot bore diameter, as drill bits in that size are not available.
  • 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 to the right 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.

Repairing a Damaged Tapped Hole
Table Tapping Guide
Click to Enlarge

Once the TTT001(/M) guide is properly aligned over the hole, use the TW25 Hand Tap Wrench with a 1/4"-20 tap (Item # 71598) or an M6 tap (Item # 71498) 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.
