Chain punch
A chain punch is a hand tool used to drive out or caulk pins when adjusting the length of roller chain or replacing connecting links. It is struck at the rear end with a hammer, and the tip pushes the pin out. The main types are the primary punch, which breaks the caulked portion and starts the pin moving; the secondary punch, which pushes the pin out completely from the outer plate; and the caulking (swaging) punch, which spreads the tip of a connecting pin to lock it in place. Pin diameter varies with the chain number (such as RS40), so punches are supplied by applicable size. They are normally used with the chain placed on a support such as a chain vise, and are used in plant maintenance and for chain replacement on conveyors and drive units.

How to choose Chain punch
-
1. Select the applicable size that matches the chain number
Pin diameter is determined by the chain number, so punches are divided by applicable chain (RS15, RS40 to 60, RS140 to 240, etc.). Caulking punches are often for a single size, such as RS40 or RS50, so confirm that they match the chain number in use.
-
2. Distinguish between primary, secondary and caulking uses
Pin removal generally starts with the primary punch to break the caulked portion and finishes with the secondary punch to push the pin out fully. A caulking punch is used for assembling connecting links. Prepare the required types for the task, and keep a set ready if both removal and assembly are performed.
-
3. Check that the tip diameter is smaller than the pin diameter
If the tip diameter is larger than the pin diameter, it will not enter the plate hole and the pin cannot be pushed out. If it is too small, the tip is more likely to bend or break. Confirm against the chain pin dimensions that the tip can pass the pin all the way through while retaining the required strength.
-
4. Choose the overall length according to chain size and working posture
Overall lengths of listed products range from 52 to 120 mm, and longer lengths tend to be used for larger chains. Longer punches are easier to grip and keep the hands away from the hammer. Shorter punches are easier to handle in tight spaces where the chain remains mounted on equipment. Confirm that the length fits the working space.
-
5. Confirm the material can withstand impact
Because punches are struck repeatedly with a hammer, the tip may wear or chip, and the rear end may mushroom. Check the body material, such as hardened tool steel, and when used for removing pins from high-strength chains, give particular priority to durability.
