Compatible with BT1855, BT1855K, BTFP12233, BT1855K (10152000, 12340000) and DWFP12233 models, this piston driver is engineered for maximum reliability and performance in demanding applications. Key Features and Benefits: Precision manufactured from aerospacegrade aluminum for exceptional strength, lightweight performance, and long service life. Utilizes UNILOK technology, which hydraulically crimps the grooves of the shaft to secure the piston driver and prevent it from loosening during operation. Heattreated for hardness and wear resistance, allowing for consistent performance under volume and heavyduty use. Annealed at the threaded end to improve ductility, enhancing shock resistance and reducing the chance of damage during impact or repetitive stress. Practical Applications: Ideal for professional carpenters and contractors working with nailers that require consistent and dependable driving action. Suitable for workshop environments where pneumatic nailers are in frequent use and downtime due to part failure must be minimized. Reliable choice for onsite construction projects requiring precision fastening over prolonged periods without unexpected breakdowns. Material and Performance Advantages: Aerospacegrade aluminum construction combines strength with reduced weight for easier handling and smoother function. UNILOK hydraulic crimp design creates a secure, lasting connection between shaft and piston, eliminating common loosening issues. Optimized heat treatment process ensures resistance to wear while maintaining toughness for longterm use. This piston driver offers the right blend of durability, precision, and compatibility for users who need a component they can trust in their BT1855, BT1855K, BTFP12233, and DWFP12233 tools.
