SPEEDAIRE Needle Scaler Kit 1/4 NPT
This SPEEDAIRE needle scaler kit is an in-line pneumatic tool built for industrial duty cycles. It includes angle chisel, blade chisel, flat chisel and needle scaler attachments plus a carrying case. The tool suits maintenance crews and metalworkers who need to remove rust, scale or coatings with compressed air.
Practical limits of 90 psi air supply
The scaler requires 90 psi operating pressure and delivers 4,600 blows per minute with a 1 17/32 inch stroke. Average air consumption is 3.2 CFM during a 15 second run while full-load demand reaches 13.0 CFM. A minimum 3/8 inch hose is needed to sustain flow without excessive pressure drop.
Install with adjustable collar and lever throttle
The housing lock uses an adjustable collar for quick bit changes and the throttle lever controls speed during operation. California Proposition 65 warnings apply because the product contains chemicals known to cause cancer and birth defects. Users must supply a compatible compressor and hose meeting the pressure and flow requirements.

Questions about this item
Which kit configuration should I choose for removing heavy scale versus light rust?
The single kit includes angle chisel, blade chisel, flat chisel and needle scaler attachments so you can swap between broad scraping and fine needle work without buying extra parts.
What does 4 600 blows per minute mean when I am actually using the tool?
The needle scaler delivers 4 600 impacts every minute at 90 psi, giving rapid scale removal while the adjustable collar lets you set the depth of each stroke.
Will my 3/8 inch hose and 90 psi compressor run this scaler at full speed?
Yes, the tool needs 3.2 CFM average at 90 psi and a minimum 3/8 inch hose, so a standard shop compressor and hose meet the requirement.
