DETYI 2-in-1 Chainsaw Chain Breaker and Rivet Spinner — Bench-Mount Tool with Hardened Pins

DETYI's 2-in-1 Chainsaw Chain Breaker and Rivet Spinner combines a chain pin press and a linking spinner in one compact tool for breaking, fitting, and rejoining chainsaw and ordinary roller chains.

This compact workshop tool brings two essential chain tasks into a single, robust device: pushing out rivets to separate chain links, and spinning rivets back in to reconnect or replace links. Designed for hobbyists, arborists, and DIY mechanics, the unit includes multiple anvils and hardened bits so it adapts to common chain pitches and sizes while mounting holes let you fasten it to a bench for stable, one-handed operation.

How does the DETYI 2-in-1 tool simplify chain repairs?

The tool integrates rivet removal and rivet spinning into a single fixture so you avoid swapping separate devices and juggling small parts. Its lever and anvil design control pressure precisely, reducing the risk of bent links or broken punches when compared with improvised methods.

• Two functions in one compact body: breaker and spinner.
• Replaceable quenching drill bits for long life and accuracy.
• Bench-mount holes for steady, repeatable operation.

What chain sizes and types will this unit work with?

DETYI includes five anvil molds to match a variety of chain profiles, making it compatible with many ordinary roller chains and most common chainsaw chains. The set’s adjustable anvil and multiple pins let you fit different pitches and widths without improvised shims.

• Five chain molds for broad compatibility.
• Three hardened drill pins to push rivets cleanly.
• Anvils sized for common chainsaw and industrial roller chains.

How do I use the tool safely and effectively?

Align the punch on the rivet center, turn the lever slowly and apply steady pressure—do not force the punch to avoid breakage. For reassembly, align the rivet head with the link and rotate the spinner handle until the rivet seats; finish with proper tensioning of the chain.

• Center the punch and press gradually; avoid abrupt force.
• Use the correct anvil and drill pin for the chain pitch.
• Mount the base plate to a bench for a secure working position.

What comes in the kit and how durable is it?

The kit ships with three quench-treated drill bits, three anvils, two hex wrenches, and the main tool with an ergonomic anti-slip handle. Hardened parts and quenching treatment give the working components strong wear resistance for frequent workshop use.

• Included: 3 hardened drill pins and 3 anvils for varied chain sizes.
• 2 hex keys for adjustments and anvil changes.
• Anti-slip collodion handle for comfortable, secure pressing.

Who this tool is for: If you regularly maintain chainsaws, repair roller chains, or run a small equipment shop, this DETYI 2-in-1 chain breaker & rivet spinner saves bench space and streamlines routine chain service. It suits weekend woodcutters, professional arborists needing field-capable repairs, and small engine mechanics who prefer a durable, bench-mountable tool with multiple anvil options. The unit is intended for mechanical chain work only; follow safety procedures, use eye protection, and do not attempt repairs beyond your comfort level.
