SPEEDAIRE

SPEEDAIRE 45NW68 Air Hammer 3.2 CFM 3/8 in

SKU CH-J5MR-SKNGK

Heavy-duty pneumatic air hammer delivers 1,500 blows per minute with 3.2 CFM average air consumption and 3/8-inch NPT inlet

  • Heavy-duty impact power for tough demolition jobs
  • 2 CFM average consumption keeps compressor demand manageable
  • 1,500 blows per minute delivers rapid material removal
  • 3/8 in NPT male inlet fits standard air lines
  • 498 in round shank accepts common chisel bits

Heavy-duty air hammer for demanding tasks

This SPEEDAIRE air hammer is built for heavy-duty pneumatic work. It delivers 3.2 CFM average airflow and operates at 90 psi with 13 cfm air consumption. The tool suits technicians and workshops that need reliable impact force for cutting, chipping or riveting jobs.

Round shank and 3/8 in NPT inlet simplify setup

The 0.498 in round shank accepts standard chisels held by a chisel-type retainer. A 3/8 in NPT male air inlet connects directly to common shop lines, while the 1/4 in minimum hose size keeps pressure drop low. At 1,500 blows per minute and a 3 5/16 in stroke, the hammer provides consistent power for daily use.

Replaces lighter hammers when material removal is

Upgrading from a standard-duty model makes sense when you face hardened steel, thick rust or heavy rivets that stall lower-blow tools. The 13 cfm demand means you need a compressor that can sustain that flow; if your supply is limited, the hammer will not reach full speed. Buyers who only do occasional light panel work will not need this capacity.

Questions about this item

What air inlet standard and size does the SPEEDAIRE 45NW68 use, and what airflow does that cap in practice?

It uses a 3/8 in NPT male inlet and consumes 13 cfm at 90 psi, so your compressor and hose must sustain that flow continuously.

What shank size and collar shape are required for chisels to fit this air hammer?

Chisels need a 0.498 in round shank and a compatible round collar to seat in the chisel-type retainer.

How do you install a chisel in the retainer, and what step is often missed?

Insert the chisel shank into the retainer, then tighten the retainer fully so the collar locks the tool; skipping the final tightening lets the chisel eject under vibration.
