The Bore Of The Hollow Needle

If you’re a sewer, you’re probably familiar with the term “the bore of the hollow needle.” It’s the diameter of the hole at the tip of a hypodermic needle. But what does that mean for you?

Well, if you’re trying to inject something through the needle, the bore is the size of the opening that the substance has to pass through. That’s important to know because the bigger the bore, the faster the substance will flow.

But that’s not the only thing that matters. You also have to consider the length of the needle. The longer the needle, the more distance the substance has to travel, which means it will flow more slowly.

So, if you’re trying to inject something quickly, you want a needle with a large bore and a short length. But if you’re trying to inject something slowly, you want a needle with a small bore and a long length.

Of course, you also have to take into account the viscosity of the substance. The thicker the substance, the harder it will be to push through the needle.

In the end, it all comes down to personal preference. Some people prefer a needle with a large bore and a short length, while others prefer a needle with a small bore and a long length. It really depends on what you’re trying to inject and how quickly you want it to flow.
