Built for intensive surface-preparation work, the Chicago Pneumatic CP0456-LESAR Straight Needle Scaler combines a 4,300 BPM impact rate with a 0.94" bore and 1" stroke to remove rust, paint, scale, and other surface buildup. Its 19 x 1/8" (3 mm) needle capacity provides a three-needle configuration for concentrated impact coverage, while the straight design and 8.62" length make it suitable for industrial maintenance and production work.
The CP0456-LESAR uses a 1/2" quarter-octagon WF chisel shank (a quick-change-style shank for compatible scaling and chipping accessories) and a safety lever starting system. Its 10 CFM air consumption at load, 3.53 lb weight, and 25.7 m/s² vibration level define the pneumatic requirements and operating characteristics of this compact straight scaler. Chicago Pneumatic also specifies a quick-change collar retainer and steel housing for the CP0456 series.

- Chipping and scaling — using compatible 1/2" quarter-octagon shank accessories for appropriate light chipping work.
FAQs:
- Q: What is the CP0456-LESAR designed to remove?
A: The CP0456-LESAR is designed for surface-preparation work such as removing rust, paint, and scale from compatible surfaces. Chicago Pneumatic positions the CP0456 series for intensive use. - Q: How many needles does the CP0456-LESAR use?
A: The manufacturer specifies a needle capacity of 19 x 1/8" (3 mm), with three needles in the stated configuration. - Q: What is the difference between CP0456-LESAR and CP0456-LASAN?
A: The catalog identifies CP0456-LESAR as having the same features as CP0456-LASAN with a weld-flux chisel configuration. The LESAR is the shorter model at 8.62" and 3.53 lb, while the LASAN is 16.26" and 5.95 lb. - Q: What air supply does the CP0456-LESAR require?
A: The manufacturer specifies 10 CFM air consumption at load, a 1/4" air inlet, a 3/8" minimum hose diameter, and 90 PSI maximum dynamic air working pressure. - Q: What does the 1" stroke mean?
A: Stroke is the distance the internal piston travels during its impact cycle. The CP0456-LESAR has a 1" (25.4 mm) stroke, providing the specified travel for its 4,300 BPM impact action.
