Bench Chain Breaker for Five Pitch Sizes

This bench-mounted chain breaker handles 1/4", 3/8" Low Profile, .325", 3/8" and .404" pitch saw chain rivets. It is built for professional workshops and frequent users who repair chains or assemble loops from bulk reels. The sturdy frame and ergonomic handle reduce fatigue during repetitive rivet removal.

Simple Setup With Included Anvil And Punches

Installation consists of bolting the unit to a bench and selecting the correct anvil slot for the chain pitch. The package supplies a standard punch, a 90-Series punch for .043" gauge chain, and a multi-pitch anvil. The most common error is using the wrong punch or anvil position, which can damage the rivet or tool.

Manual Force Limits And Single-Rivet Operation

The tool relies on hand leverage, so very hard or corroded rivets may require significant effort or pre-treatment. It processes one rivet at a time, making full-loop assembly slower than powered rivet spinners. The fixed anvil geometry does not accommodate pitches outside the five listed sizes.

Questions about this item

How do I confirm the bench chain breaker punches rivets cleanly on a .325 pitch chain after setup?

Place a .325 pitch chain on the anvil, align the standard punch over a rivet, pull the ergonomic handle down firmly, and check that the rivet is pushed clean through without damaging the link plates.

Which components are included with the 24548B and what must be purchased separately?

The box contains the bench model chain breaker, a standard punch, a punch for 90-Series chain (.043" gauge), and an anvil for 1/4", 3/8" Low Profile, .325", 3/8" and .404" chain. Replacement parts are available separately.

Should I choose the standard punch or the 90-Series punch for .043" gauge chain?

Use the 90-Series punch (.043" gauge) for 90-Series chain; use the standard punch for all other compatible pitches including 1/4", 3/8" Low Profile, .325", 3/8" and .404".
