Chicago Pneumatic CP 0009F Rotary Hammer

Chicago Pneumatic CP 0009F Rotary Hammer (Rotary Release) — Spline Drive

When you need a compact pneumatic rotary hammer that can drill hard material all day and instantly switch into a dedicated chipping hammer, the Chicago Pneumatic CP 0009F is built for that exact reality. It’s part of Chicago Pneumatic’s sinker and surface rock drill family—tools designed to feel balanced in the hands, stay controllable under load, and keep delivering consistent performance over a long service life.

The CP 0009F brings a jobsite-ready mix of speed, durability, and versatility to concrete drilling, doweling work, masonry anchor setting, and maintenance tasks where cords are a hassle or electric tools get abused.

What makes the CP 0009F different

Chicago Pneumatic designed these tools around real-world handling: a streamlined body with smooth contours, a side exhaust, and a “flat back” profile that makes the tool easier to manage in quarry, mine, drilling, and doweling work.

The internal design uses a main valve and cylinder-porting concept intended to help maintain a consistent drilling speed over a long service life, while an effective lubrication approach helps keep working parts protected. Standard and silenced versions are available across the broader family to fit different requirements.

And the headline feature is the one you’ll feel immediately: Rotary Release.

Drill mode to hammer mode in seconds (Rotary Release)

The CP 0009F is both a drill and a chipping hammer. With a push of the rotation release button, you can quickly convert it from rotary hammer drilling into hammer-only operation—ideal when a task goes from “make the hole” to “chip/clean/scale” without swapping tools.

That means fewer tool changes, fewer interruptions, and a smoother workflow on repair, retrofit, and maintenance jobs.

Notable features

• Streamlined design with smooth contours, side exhaust, and “flat back” handling profile
• Main valve and cylinder-porting concept to help maintain constant drilling speed over long service life
• Working parts continually protected by an effective lubrication system
• Rotary Release button converts the tool from drill mode to hammer mode quickly
• Built-in oiler for continuous lubrication support
• Teasing throttle for more precise trigger control and better starts
• Cushioned piston design for smooth operation and long tool life
• Optional muffler available for noise reduction (when you need it)
• Spline drive chuck for solid engagement with the steel

Built for construction and maintenance work

The CP 0009F is designed for a wide variety of construction and maintenance applications, including:

• Driving or setting masonry anchors
• Drilling holes in concrete, brick, and rock
• Quarry, mine, drilling, and doweling work where handling and control matter

As a hammer in hammer-only mode, it can also be used for:

• Chipping
• Scarifying
• Scaling
• Cleaning welds

If your work bounces between drilling and surface removal or cleanup, this is exactly the kind of combo tool that keeps you moving.

Why contractors like spline drive on this tool

The CP 0009F uses a spline drive chuck setup—commonly chosen when you want dependable engagement under repeated impact and a setup that holds up to serious drilling and hammering cycles. It’s a practical fit for construction and industrial maintenance jobs that punish lighter-duty couplers.

Quick checklist for best results

1. Run clean, correctly regulated compressed air (most performance figures are referenced at 90 psi).
2. Keep lubrication working for you (the CP 0009F includes a built-in oiler).
3. Match the spline-drive steel to the material and the job.
4. Use Rotary Release to shift from drilling to hammer-only work without changing tools.

Bottom line

The Chicago Pneumatic CP 0009F Rotary Hammer (Rotary Release) is a compact, professional-grade pneumatic rotary hammer built to drill confidently in concrete, brick, and rock—and then instantly convert into a hammer for chipping, scaling, scarifying, or weld cleanup. With its spline drive chuck, high impact rate, built-in oiler, and jobsite-focused handling design, it’s a smart choice when you want one air tool that stays productive across drilling and hammering tasks.
