DID KM500R Chain Cut & Rivet Tool for 520–532 Chains — Forged Steel, Compact Case

The D.I.D KM500R Chain Cut and Rivet Tool is a compact, forged-steel tool that cuts 520–532 motorcycle chains and flares and rivets pin heads for reliable on-bike repairs.

Compact yet robust, the KM500R was built for heavy-duty chain work: cutting chain links, pressing in connecting link plates and forming rivet pin heads cleanly. It handles common sizes used on motorcycles and ATVs (520, 525, 530/50, 532) and ships with a plastic storage case so you can keep it in a toolbox or tail bag. The tool’s hardened construction and engineered pin flaring reduce the risk of over-riveting or off-center rivet heads, producing consistent, serviceable joints without the need for large bench presses.

How does the KM500R manage cutting and sizing different chain types?

The KM500R uses a hardened cutting and driving system sized to fit 520, 525, 530 (50), and 532 chains. The tool’s pin aligns precisely with the chain rivet, allowing clean removal of links while minimizing damage to adjacent plates and rollers. After cutting, the same unit can be used to press plates back into position.

• Fits 520/525/530(50)/532 chain pitches without adapters
• Hardened drive pin for repeatable, clean cuts
• Integrated plate press to seat connecting links
• Compact footprint for use at roadside or in a shop

What stopping over-riveting or misaligned rivet heads?

Instead of brute-force hammering, the KM500R controls forming of the rivet head with a press-action driver that flares the pinhead evenly. The design helps center the pin and creates a uniform head profile so the joint moves and wears predictably. That lowers the chance of a high or off-center head that shortens chain life or requires rework.

• Engineered flaring die minimizes over-rivet formation
• Guided driver keeps pin alignment during pressing
• Reduces need for secondary finishing or reworking rivets
• Suitable for roadside or garage rivet finishing

How durable and portable is this tool for field use?

Forged from professional-grade steel, the KM500R stands up to frequent use and the forces required to cut and flare heavy chains. Its compact design fits in the supplied plastic case so you can store it with spares or carry it on long trips. The construction balances strength with manageable weight for technicians and riders who need dependable emergency repairs.

• Forged steel body for longevity and heavy-duty usage
• Small footprint and included plastic case for transport
• Simple mechanical operation—no hydraulic or electrical power needed
• Serviceable parts and straightforward maintenance

Who is this for? The D.I.D KM500R is aimed at motorcycle mechanics, track crews, and serious riders who want a reliable, portable tool for cutting and rivetting common chain sizes. It’s a solid choice for workshop use and for carrying on trips where quick, repeatable chain repairs can keep you moving without a tow.
