14 best thread milling taps
Thread milling taps are specialized cutting tools used in the manufacturing and machining industry for creating internal threads in materials such as metal, plastic, or composites. These tools are particularly useful when precision threading is required in various industrial applications. Here are some key points about thread milling taps:
Thread Milling Process: Thread milling is a machining process that involves using a thread milling tap to cut internal threads. Unlike traditional threading methods that use single-point taps or dies, thread milling taps use multiple cutting edges to gradually create the threaded hole. This method is known for its precision and versatility.
Multiple Flutes: Thread milling taps typically have multiple flutes or cutting edges. These flutes help in removing material efficiently and evenly while creating the threaded pattern.Common configurations include two-flute and three-flute thread milling taps.
Helical Path: Thread milling taps follow a helical path as they rotate and move axially into the workpiece. This helical motion allows for a smoother and more controlled cutting process, reducing the risk of chip buildup and tool wear.
Material Compatibility: Thread milling taps are designed for use in various materials, including metals like steel, aluminum, and titanium, as well as plastics and composites. The choice of tap material and coating may depend on the specific material being threaded.
Thread Size and Pitch: Thread milling taps are available in a wide range of sizes and pitches to accommodate different threading requirements. Manufacturers often provide detailed specifications to help users select the appropriate tap for their needs.
Precision and Accuracy: Thread milling taps are known for their ability to create threads with high precision and accuracy. This is crucial in industries where tight tolerances and exact thread profiles are essential.
CNC Machining: Thread milling taps are often used in conjunction with computer numerical control (CNC) machines, which can program and control the tool's movement with great precision. This ensures consistent and repeatable results.
Tool Maintenance: Proper tool maintenance, including periodic sharpening and cleaning, is essential to ensure the longevity and performance of thread milling taps.
Overall, thread milling taps are valuable tools in the manufacturing and machining industry for creating high-quality internal threads. They offer precision, versatility, and reliability, making them suitable for a wide range of applications where threaded holes are required.

User questions & answers
Question: | What pitch is the M12 tap |
Answer: | Hi there- "locking" refers to the thumb screw at the base of the back plate. You push the lock up and tighten the thumbscew down. All Proslat double and heavy duty slatwall hooks are locking. The only one that does not is the 4" single hook, which you can view by copy/pasting the following ASIN into the Amazon search bar: B00HUDH3U0 The rationale behind locking hooks is that heavy goods are to be stored on double/heavy duty hooks. We want to ensure that if you bump the hook from the bottom, the hook does not discharge from the hook channel and fall (like some other slatwall hooks and peg hooks). All Proslat hooks have a 45 degree angle of return, which minimizes chances that they will come out of the slatwall when bumped from the bottom, but does not eliminate this entirely, unless the hooks are locked in place. |

User questions & answers
Question: | The description says this is pro tap but the picture is of the regular less expensive stuff???? Which is it |
Answer: | I have used this product for 35 years are more. The shelf life is a very long time as in several years, after being opened. |
Question: | What's the shelf life of this product |
Answer: | I don't think this cutting fluid is ideal for drilling plexi-glass, though it will work and will not discolor your material. It is an oil, so clean up would involve something to cut the oil film. Here is a link to a web site that details what drill bits you need to use (standard bits tend to "grab" the plexi-glass) , and they recommend either light machine oil, or just plain water. http://www.bertram31.com/proj/tips/drill_acrylic.htm |
Question: | Is this product OK to use on clear acrylic like plexi-glass |
Answer: | I've successfully drilled stainless steel burners on a grill with a carbide-tipped drill bit. |
Question: | Hello....Would like to know if this product works for stainless steel, drilling and or tapping???...thanks...Bob |
Answer: | Neither describes it very well, It isn't so thin it runs away from working area but not so thick you have to use more than necessary. I think it's called capillary action, it moves it self to the work, especially drilling. It is better than a previous product that for some reason skyrocketed the price, like $180. for a quart. |

User questions & answers
Question: | In the features it's mention •Reversible for male and female hole centering can someone explain this |
Answer: | usa |
Question: | How much travel does the spring point have |
Answer: | No. More detail for you: You need a tap or a tap wrench with a dimple in the center of the tap (or the top of the wrench body if the tap wrench totally encloses the top of the tap). Not all taps or tap wrenches have one. Clamp the work to your drill press table. Drill the pilot hole. Remove the drill bit and chuck this tool in the drill press. Put the tap in the pilot hole and bring the quill down to engage the point on this tool in the dimple in the tap / tap wrench. Compress the spring and lock the quill. Operate the tap wrench BY HAND as you normally would. NO POWER on the drill press. This just provides pressure and assures alignment. For deep holes, you may run out of spring pressure, but the tap should be so well engaged that you don't need the guide any more. Just keep tapping and lift the quill if it's in your way. |
Question: | Where is this made, usa or china |
Answer: | The drill size for a 16mm tap is 35/64. a 1/2 inch hole is too small and will likely break the tap. If I am reading the question right you should ask what drill size for a 16mm tap. There are also handy tap/drill charts online. Hope this helps! |
Question: | Does this work like a punch for starting a bit so it doesn't walk away from there you want to drill the hole |
Answer: | I am not clear on the "x45" aspect; assuming that is half the angle of the bolt at the top just below the hex, where it meets the wheel rim ( I like VW's but am not intimate with them).; then yes, this tap will "chase" your female thread(s). This is a quality tap. But be warned that threads have 'classes of FIT', which relates to whether the tread is of ~loose fit, or Tight, being negligible clearance therefore foreign matter (crud) could seize the male/female contact, where as a loose fit would tolerate the dirt/foreign matter. The point I am trying to make is you have no idea what thread fit VW gave the lug bolt female thread. There is the possibility this tap will cut your female thread to be a greater clearance fit. If your simply trying to remove contaminates/crud you might look for a metal (steel or brass) round brush and use that. 14mm= .551 so 9/16" is close (1/4 Pipe thread might do the job and those are found in most any hardware or farm store, or best might be a 28 gauge shot gun brass bore cleaning brush, which a good gun shop might have. 28 gauge is a standard gauge but not common. Amazon might have such . All this said, I made a piece using this tap, and feel that it did a fine job and the fit did not seem loose. If you have already tried the brush route, I'd buy this tap with decent confidence. More than you likely wanted t o know__________Good luck |

Product Introduce
- Spiral point taps are also called screw-point taps, suitable for processing through-hole threads and deep-hole threads. Featured with high strength, fast cutting speed, clear tooth pattern and long life.
- Spiral point tap is a deformation of the straight flute tap. The cutting edge of the straight flute is slanted to form an angle, and the chips are discharged forward along the direction of feed. The through-hole threads should be preferentially drilling by spiral point taps.
- Made of high speed steel (HSS), threading tool is good for general purpose applications, offering high hardness, toughness and wear resistance.
GENERAL SELECTION BASIS
- Use with tapping oil to get higher quality thread and more durable taps. It is easy to cause damage for uneven force if the machine taps are used by hand.
- When selecting the cutting speed, please consider the tap material, type, thread teeth, hole shape, effective diameter of the bottom hole, processing material and cutting oil .
- Cutting oil is lubrication, cooling and anti-sticking. Be sure to select the appropriate cutting oil for complex tapping process.
