Chicago Pneumatic CP 0009CS Rotary Hammer - Round 3/4” X 3-3/4”

Chicago Pneumatic CP 0009CS Rotary Hammer (Round 3/4” × 3-3/4”) — Rotation Release

When you need a compact pneumatic rotary hammer that drills clean holes and can immediately switch into hammer-only duty, the Chicago Pneumatic CP 0009CS hits the sweet spot: fast, controlled, and built for real jobsite abuse. It’s part of Chicago Pneumatic’s combi drill/hammer platform—built for drilling in concrete, brick, and rock, then converting into a chipping hammer for surface work with a simple rotation-release action.

Built for quarry, mine, drilling, and doweling work, the CP 0009 family uses a streamlined, easy-to-handle body with smooth contours, side exhaust, and a “flat back” profile that helps keep the tool steady when you’re working close to a wall or pushing overhead. The internal design emphasizes consistent speed through a long service life, while continuous lubrication helps protect the working parts under daily use.

What It Does Best (Real-World Applications)

The CP 0009CS is designed for construction and maintenance tasks where you want both drilling and hammering from one air tool:

• Driving or setting masonry anchors
• Drilling holes in concrete, brick, and rock
• Chipping and edge cleanup
• Scarifying and surface prep
• Scaling and general material removal
• Cleaning welds and knocking slag/spatter

This is the kind of tool that earns its keep when you’re bouncing between drilling and demolition work and don’t want to swap tools every time the task changes.

Notable Features

Chicago Pneumatic’s sinkers and surface rock drills are well suited sinker drills that are ideal for a range of drilling applications. The pneumatic drill has a streamlined design that incorporates smooth contours, a side exhaust, and a “flat back” that makes them easy to handle in quarry, mine, drilling, and doweling work.

The design also provides a main valve and cylinder-porting concept that helps maintain constant drilling speed throughout a long service life. Working parts are continually protected with an effective lubrication system. Standard and silenced versions are available in a range of weights and sizes to fit any requirement.

The CP 0009 is designed for a wide variety of construction and maintenance applications such as driving or setting masonry anchors and drilling holes in concrete, bricks, or rock. As a hammer, these tools can be used for chipping, scarifying, scaling, and cleaning welds.

These versatile tools are both a drill and a chipping hammer. A push of the rotation release button easily and quickly converts the tool to a hammer.

Performance & Key Specifications

Here are the key specs customers typically care about when matching a rotary hammer to the job:

• Shank / steel size: Round 3/4” × 3-3/4”
• Impact rate: 3420 blows per minute (bpm)
• Max drilling depth: 17.5 inches
• Overall length: 14-3/4 inches
• Net weight: about 8.82 lb
• Air consumption (at 90 psi): 19 cfm
• Typical drilling rate guidance (at 90 psi): around 12 in/min in hard rock/concrete (job conditions vary)

The CP 0009CS configuration is commonly specified as a round-chuck version with a collared head / hose-tail style air inlet, and it’s frequently offered in a silenced/muffled setup depending on how the tool is ordered.

Why Crews Like the CP 0009CS

This tool isn’t about gimmicks. It’s about doing two jobs well with one air tool.

• Excellent power-to-weight feel for overhead work, tight spaces, and all-day handling
• Teasing throttle for better control when starting holes or working brittle masonry
• Cushioned piston design for smoother operation and durability
• Effective lubrication system to protect internal parts and extend service life
• Quick drill-to-hammer conversion with rotation release so you can switch tasks immediately

If you’re setting anchors all morning and chipping or cleaning surfaces all afternoon, the conversion feature is the difference between staying productive and wasting time.

How to Set It Up for Best Results

1. Use clean, dry, properly regulated compressed air (many published performance figures are based on 90 psi).
2. Keep lubrication consistent. The system is designed to protect the working parts, but air prep still matters.
3. Match the steel correctly: this model is for 3/4” × 3-3/4” round shank tooling.
4. Choose your working mode based on the job: drill for holes and anchor setting, hammer mode for chipping, scarifying, scaling, and weld cleanup.

Bottom Line

If you want a pneumatic rotary hammer that can live on a jobsite—drilling anchors one minute, then switching to chipping, scaling, or surface cleanup the next—the Chicago Pneumatic CP 0009CS (3/4” × 3-3/4” round shank) is a strong, proven choice. It’s compact, controllable, and built around a design that prioritizes steady performance, continuous lubrication, and fast drill-to-hammer versatility.
