13 best threading holders

Threading holders, also known as threading tool holders, are essential components in machining and metalworking processes. They are specifically designed to hold cutting inserts for threading operations, providing precision and efficiency in creating threads on various workpieces. Here's what you need to know about threading holders in the context of turning inserts, indexable inserts, cutting tools, and industrial applications:

**1. ** Functionality: Threading holders are engineered to secure indexable threading inserts firmly. These inserts have multiple cutting edges and can be rotated or flipped to a new edge once one edge becomes dull, enhancing the tool's longevity and cost-effectiveness.

2. Types of Threading Holders: There are different types of threading holders designed for various threading applications, including internal threading and external threading. Internal threading holders are used for creating threads inside holes, while external threading holders are used for creating threads on the outer surface of a workpiece.

3. Material and Durability: Threading holders are commonly made from high-quality materials such as carbide, steel, or other durable alloys. The choice of material depends on the specific application requirements and the type of material being machined.

4. Indexable Inserts: Threading holders are designed to accommodate indexable inserts, which are replaceable cutting tips that can be easily replaced when worn out. These inserts come in different shapes, sizes, and threading profiles to suit various threading operations.

5. Precision and Accuracy: Threading holders are engineered with precision to ensure accuracy and consistency in thread cutting. They are designed to minimize vibration and provide stable cutting conditions, resulting in high-quality threads on the workpiece.

6. Versatility: Threading holders are versatile tools used in a wide range of industries, including automotive, aerospace, manufacturing, and engineering. They are employed in both CNC (Computer Numerical Control) machining centers and conventional machining setups.

7.Cutting Tools and Industrial Scientific Application: Threading holders are essential components of cutting tools used in the industrial scientific field. They are utilized in scientific research, manufacturing processes, and various industrial applications where precision machining is required.

In summary, threading holders play a vital role in the machining industry, allowing for efficient and accurate thread cutting operations. They are integral parts of cutting tools and are widely used in industrial and scientific applications where precise threading is essential for the production of high-quality components.

User questions & answers

Question: Is this really stainless steel
Answer: No, this die stock is made specifically for round dies. To hold your die properly you need a die stock that is made for a hex die that is 1 1/2 inches across the flats. In fact, the hex die would have a dimension of about 1.73 inches from corner to opposite corner so it wouldn't even fit in this die stock.
Question: Is this also appropriate for a hex die that is 1 1/2 inches across the flats
Answer: the total length for this part is 315mm
Question: How long is it handle tip to handle tip
Answer: I haven't measured it since my calipers won't read in 10ths of one thousandth of an inch but I can tell you that it is a close enough fit on a 1.500" die that if the handle is substantially colder than the die (contraction differential ) it will not fit, the tolerances are that close. Ask me how I know. : )
Question: What is the actual max inside diameter that this tool accommodates? I have 1 5/8" die that I need handle for
Answer: If your mini lathe can use a boring bar with a shank diameter of 13mm and then you can buy it!

User questions & answers

Question: What is the size of the boring bar (diameter or width)? I have a 1/2" tool holder
Answer: the smallest diameter hole of the internal thread can cut is 12mm
Question: What is the smallest diameter hole the internal thread can cut
Answer: Shank size is close to 3/8” diameter.
Question: shank size
Answer: These will cut 16 to 48 TPI standard 60 degree threads. They are not designed to cut acme threads, and most acme threads are coarser than 16 TPI.
Question: what pitch of thread can be cut with these tool will it cut acme threads
Answer: As far as I can tell, the handles may very well be, but the body appears to be cast. Seems to be well made, though. I'm not disappointed and will buy another if needed, to accommodate bigger bodied dies.

User questions & answers

Question: Dont you have a tool with 25×25 shank sizes
Answer: I have cut multiple standard and got away with a few metric threads. I haven't cut anything smaller than 3/8-16 all the way up to 1.5"-6 comfortably i should have sized up but in a pinch it worked out fine. I also purchased left and right inserts for them and have been very happy with them
Question: What helical angles or threads can you cut with this indexing blades
Answer: This device fits an mt2 only. For an mt3 tailstock you would need a mt3 to mt2 adapter.
