Sunex Heavy-Duty Long Barrel Air Hammer

Description

Inside heavy diesel repair bays, the Sunex Long-Barrel Pneumatic Air Hammer shears rusted suspension bolts, separates stubborn ball joints, and drives frozen kingpins with punishing 2200 BPM impact blows. Operating on 90 PSI shop air, the long-barrel piston design delivers a long 3-3/4-inch stroke to generate maximum impact energy on heavy truck hardware. Heavy equipment mechanics break frozen suspension parts in seconds. The pneumatic hammer consumes 4.0 CFM at 90 PSI.

• Long 3-3/4-inch stroke delivers powerful 2200 blows per minute to shatter rusted heavy commercial truck fasteners cleanly.
• Accepts standard 0.401-inch Parker-taper chisel shanks, matching commercial automotive cold chisels and scrapers cleanly.
• Ergonomic aluminum handle with contoured rubber grip dampens destructive impact shock transfer into hands cleanly.
• Touch-control feathering trigger regulates impact blow speed, allowing delicate panel separation or full impact power.
• Quick-change chisel spring retainer allows fast bit changes between cold chisels, sheet metal cutters, and punch bits cleanly.
• Alloy steel barrel is case-hardened to resist internal bore scuffing under multi-hour commercial fleet maintenance cycles cleanly.

Solid cast aluminum forms the handle and rear cylinder housing, finished in industrial black powder coat with molded ergonomic rubber grip inlays. The percussion barrel uses case-hardened alloy steel, precision-machined to resist internal bore scuffing under high-cycle hammering. Sized for mechanic toolboxes, the bare air chisel hammer weighs 5.5 lbs, measuring 10.5 inches long, accepting standard 0.401-inch Parker-taper chisel shanks.

Long-Stroke Percussion Bench Limits

Pneumatic dynamometer testing confirms the hardened steel hammer piston delivers 2200 blows per minute at 90 PSI line pressure, delivering six foot-pounds of per-blow impact energy. Shearing a 1/2-inch rusted Grade-8 automotive suspension bolt completes in under 3.5 seconds without barrel stall. The quick-change retainer spring retains 0.401-inch chisel shanks securely under 180 lbs of reverse pull force, preventing chisel ejection during heavy hammering cycles.

Chassis Demolition Negative Selection Filter

The variable-speed trigger permits feathering impact blows for delicate exhaust sheet metal separation. Do not buy this heavy long-barrel air hammer for light sheet metal sculpting requiring short-stroke body hammers, delicate interior trim work, or operating on small 2-gallon finish compressors lacking 4 CFM delivery.

• Add four drops of air tool oil into the inlet nipple daily before connection to clean shop air lines.
• Inspect chisel shanks for mushroomed striking ends, grinding shanks flat before inserting into the barrel.
• Check the quick-change spring retainer for mechanical tension cracks every fifty operating hours.
