How to Tune Fixed Blade Broadheads

In order for a fixed-blade broadhead to fly directly to the target that you are aiming for, your setup needs to be in check at all times.

Broadheads are not forgiving, like field points can be. They will expose the flaws in your setup.

Let’s dig into how you can tune up your broadheads, so you can hit your mark.

The Wrench

Having the proper tools is extremely important to make things work in your favor as much as possible. Due to their blade layout, different broadheads require different tools. Make sure you have the right wrench to go with your particular broadhead.

You should never rely on ‘finger tight’, as it won’t stay tight, and you will lose they will most likely never be just right. If you don’t have the proper wrench, then visit go to your local bow hunting shop, or get it online.

Match the Spine to the Broadhead

The flight of your broadheads has less to do with the broadhead itself, but more with the arrow. The flight will be greatly affected by the amount of stiffness of the spine. The best thing to do is to match the stiffness of your arrows to your bow, then match the broadhead to the arrow.

Inspect the Arrow

When it comes to the accuracy, the arrow plays an important role. For this reason, before you put a broadhead or an insert in your arrow, don’t forget to inspect it.

The cut end of your arrow needs to be square and be completely free of defects. If the arrow is not mechanically sound, inserts will not seat properly. A squaring tool can help in repairing any defects on the cut end and allow the insert to be properly seated, and your arrows to fly true.

Match the Grain

Practice shooting your bow with field points first, then once you are locked in you can make the switch to broadheads.

Choose a broadhead with the same grain as the field point in which you just sighted in your bow with. Tips with different grain will have different weight, which will in turn mess up your previous target practice and alignment.

Go for Quality

I recommend you buy the highest grade broadheads that you can reasonably afford. Carbon Express produces some fine heads for bowhunting.  The reason is, like any other piece of gear, is that quality comes at a price. Your broadheads are one place you don’t want to try to save a few bucks.


Align your broadhead such that the blades line up with the fletch. Missing this detail will cause your arrows to drift to either side, and you will be left frustrated with poor accuaracy. Also align the veins with the blades once the broadheads are attached. You will be much happier with your results with these small adjustments.

Right the Rest

When it comes to your broadhead performance and arrow flight, your rest is an important factor. If it isn’t exactly where it needs to be, don’t be afraid to change it!

Try paper tuning your bow to check your rest positioning. When you can see tears in the paper, you’ll know your rest requires an adjustment.

Sharpen the Blades

A dull broadhead will not have the penetrating power or accuracy of a sharp one. Use a sharpener to touch up the blades of each arrow before heading out. Shooting sharp broadheads will give you the best chance at success.

Practice Heads Make Perfect

Using a practice head will save your expensive broadheads from being unnecessarily dulled at the range. Check the flight of every one of your arrows with the practice head before putting a new sharp head on. Why waste the sharpness on a target, when you can use it on a deer?

Spin Test the Arrows

Your final check is to spin test each of your arrows on a table or bench top. Inspect each part of the arrow, then put the point on the table, holding the arrow shaft straight up and down, and give it a spin. If it has a tight, upright spin, then everything is great. If you notice that there is even a slight wobble, then you need to go back the beginning and tune it again.

Now that you’ve tuned all of your arrows, you will have powerful, true flying broadheads. All that hard work and preparation will set you up for success in the woods later.
