Arrow insert question
 

Hey all,
New to the forums, and archery in general. I do have quick question that I was hoping you guys and gals can help me with.
I was looking into some inexpensive carbon arrows -tight budget at the moment. I found a 3 pack from Allens Company that states they come with a broad head insert.
Like I said, I'm new to archery, so I have no idea what the insert it. Am I safe in assuming that the insert is, in a way, an adapter to allow you to use a broadhead? So, would that mean these arrows do not come with tips and I can not use them unless I purchase some?
Here are the arrows I am referring to:

Thanks for any and all help!

Ps: While were on the topic. Are tips interchangeable? If the arrows mentioned above do not actually come with a tip, can I just purchase a few off ebay, and install those? Or would I need to check the size, and get different inserts?
By the way, I'm just using these for backyard target shooting, no hunting or anything.

as you guessed
the inserts are inserted in the arrow shafts and allow for tips like broadheads and field points to just be screwed in
you will need to buy both a set of broadheads, and field tips for practicing
most shops and sports stores including walmart sell broadheads and field tips,
field tips for practicing are cheap, broadheads prices will vary, from like $10/ 3 pack to +$30/ 3 pack
weight of your tips will be important,
whether your using 100 grain or 125 grain points 2 most common weights

Thanks a bunch Teresec,
Am I safe in assuming that tips are interchangeable/universal? Or will different inserts require specific threading on the tips?

pretty sure they are
only issue where size is a factor is when buying replacement inserts
then they need to be matched to inside diameter of the shaft

Oh, okay. So technically, I can purchase those arrows mentioned above and pair them with these tips?

Really sorry about all the questions. Like I said, I just got into archery a week ago, so I'm still learning everything. And again, I appreciate all your help.

that should be fine
only issue the 21/64 size is slightly larger than allens 9/32

means that tip is slightly larger than allens outside diameter of the shaft
wont affect performance, just can snag when pulling out of targets
makes it tougher and loosens that insert
just something to consider

Ah I see. I'll just purchase the ones you posted. Thanks for all the help terasec.

James - all arrows come with inserts (aluminum or carbon). The reason they are not installed is that arrows should be cut to the individual's drawlength. A high speed saw is necessary to cut them (most archery shops have one, or should have one). When cut at an archery shop, they will/can install the inserts for you. If you decide to do it yourself, the inserts for carbon arrows are to be epoxyed in not glued.
