Ajax Tools Buyer's Guide: Air Hammer Attachments & Pneumatic Chisels

Why Ajax Tools?

Ajax has been manufacturing professional-grade pneumatic tool attachments for decades. Their air hammer chisels, rivet sets, scrapers, cutters, and specialty attachments are built to withstand the demands of production shops, body shops, and heavy-duty repair facilities. Whether you're splitting rusted ball joints, cutting exhaust pipes, or driving rivets, there's an Ajax tool designed specifically for the job.

This buyer's guide organizes the full Ajax lineup by application so you can quickly find the right attachment for your air hammer.

Understanding Ajax Shank Types

Before ordering, confirm which shank type your air hammer accepts:

• .401 Turn Type Shank: The most common shank for professional air hammers. Most Ajax chisels and attachments are available in this configuration.
• .498 Shank: A larger shank used on heavier-duty air hammers. Look for Ajax tools marked "0.498" for this fitment.
• Non-Turn Type Shank: Some tools like the Ajax 3185 Non-Turn Type Wide Chisel/Scraper use a non-rotating shank design.

Retaining springs and retainers are also shank-specific — see the Accessories section below.
