What is cold hammer forging?
Cold hammer forging produces accurate and durable barrels. During cold hammer forging, Tikka barrels are hammered from all sides against the mandrel inside the barrel, transferring the mirror image of the rifling machined on the surface of the mandrel. A cold hammer forged barrel has many advantages.
Is a cold hammer forged barrel good?
The cold hammer-forging process produces barrels of excellent quality. They are not common on match-grade or varmint barrels, as their accuracy is perceived to be inferior to cut- or button-rifling methods. Advantages of Hammer Forging: Hammer forging consistently produces high-quality barrels.
Who makes cold hammer forged AR barrel?
The Spike’s Tactical 8.1″ Cold Hammer Forged (CHF) 5.56 Pistol-Length Barrel is a great option for your AR pistol or SBR. Its chrome lining will give you matchless durability.
Does cold hammer forged matter?
When it comes to long life and durability, many shooters believe that a cold hammer forged barrel is superior to barrels that are button-cut. With barrels that are not cold hammer forged, under constant heat and stress, they can be more prone to throat erosion, gas port erosion.
How does a forging hammer work?
Forging hammers are used in the drop forging to form the metal between two dies. The first half of the die is attached to the anvil and the second part to the hammer. The material is placed in the lower die and then hammered with the upper one until the hot metal flows in all directions, filling the die cavity.

Why are cold hammer forged barrels?
A cold hammer forged barrel has many advantages. The CHF method provides exceptional control of the bore and groove dimensions, resulting in excellent dimensional accuracy and tolerance. A cold hammer forged barrel has smoother barrel surfaces compared to other barrel manufacturing methods such as button rifling and cut rifling.
Are hammer forged barrels better?
Domestic manufacturers seem to favor hammer forging because it allows them to produce cheaper barrels to help ther bottom line, not necessarily better barrels. A Tikka or Sako barrel is also hammer forged and is of much higher quality than the Remington or Ruger barrels.
What is cold forged steel?
Cold forging is a lot like hot forging except it is at or near room temperature. The lower temperature means that the steel is much stronger and it is much more difficult to forge. That also means the steel is more brittle and therefore more likely to crack during forging or rolling. The shape of the grains in the steel are changed through forging.
What is cold forged?
Cold forging is one variation of the forging metal-shaping process that involves forming or shaping metal parts through a process of applying powerful, localized compressive forces. Cold forging is carried out with the metal generally kept at or slightly above room temperature with the temperature always maintained at…
