Kwik-Way Boring Bars, originally produced by Cedar Rapids Engineering Company since the 1930s, are legendary in the automotive engine rebuilding industry for precision cylinder boring.
Production ended in 2013, but these durable, portable machines remain highly sought-after in the used and refurbished market.
- Portable design: Mounts directly on engine blocks or workpieces for on-site boring without moving heavy equipment.
- Versatility: Handles a wide range of bore sizes (e.g., FN model: 2.65″–5.33″). Popular models include FN, FW, FWS2, FT, FL, and smaller FWS variants common in motorcycle/ATV shops.
- Primary use: Precision boring to make cylinders perfectly round and straight for optimal engine performance.
- Beyond automotive: Widely used in air compressor shops, ocean/land oil rigs (bushing holes), infrastructure (dam locking mechanisms), manufacturing, marine (ships), heavy equipment (excavators, cranes – pin/bore alignment), oil & gas (valves, pipelines, drilling equipment), power generation (turbines, generators), and mining (large equipment repair).
Norum Equipment LLC is one of the last expert sources for fully refurbished Kwik-Way Boring Bars and customer rebuild services. We sell outright or rebuild your existing bar, restoring it to like-new precision.
- FL: $11,950
- FN / FW / FWS2: $8,950
- (Tool Kit Restore: +$850)
