Chicago Pneumatic CP0069 Sinker Drill
When you need real rock-drilling muscle in a handheld pneumatic package, the Chicago Pneumatic CP0069 Sinker Drill is built to earn its keep. It’s a heavy-duty sinker drill designed for tough drilling work in quarry, mining, concrete, and general construction, with a shape and control layout that’s meant to be handled all day—without fighting the tool.
Chicago Pneumatic’s Sinkers & Surface Rock Drills are well suited sinker drills that are ideal for a range of drilling applications. The pneumatic drill has a streamlined design incorporating smooth contours, a side exhaust and a “flat back” that makes them easy to handle in quarry, mine, drilling and doweling work.
Built for demanding drilling (and jobsite versatility)
The CP0069 is suited for serious hole-making where smaller classes bog down. It’s commonly chosen for plug holes, dowel holes, anchor holes, and rock/concrete drilling, with a design that emphasizes consistent drilling speed, strong collaring, and effective hole cleaning.
It’s also marketed as a versatile, dual-purpose tool:
The CP 0069 Rotary Hammer 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.
Why crews like the CP0069
This is the kind of pneumatic sinker drill you buy because downtime is expensive and holes still need to get drilled when the material gets mean.
- Hard-hitting 60-lb-class performance for faster progress in rock and concrete
- Excellent hole cleaning ability to keep the bit cutting instead of regrinding dust
- Trouble-free “beavertail” retainer design to improve front-end durability and reduce collar wear
- Blower lever for deep-hole cleaning (helpful when you’re pushing depth and want to clear cuttings efficiently)
- Integral oiler to support continuous lubrication in real jobsite conditions
- Double-grip handles and balanced form factor for control while collaring and drilling
Performance and key specs (CP0069)
Here are the headline numbers buyers care about when comparing sinker drills:
- Weight: 64 lb
- Overall length (with retainer): 24-1/4 in
- Impact rate: 1920 blows per minute (bpm)
- Max drilling diameter: 2-1/2 in
- Max drilling depth: 236 in (approx. 19.7 ft)
- Air consumption (at 90 psi): 130 cfm
- Chuck sizes: 7/8″ x 4-1/4″ or 1″ x 4-1/4″
- Rotation: left-hand rotation
If you want a “real-world” benchmark, published guidance for drilling rates in hard rock (at 90 psi) lists 10.2 in/min as a reference rate (use as a guide; results vary with rock type, bit, feed force, and air supply).
Design details that translate to longer service life
The CP0069 isn’t just about raw impact—it’s about staying consistent over time.
- The sinker drill line’s design includes a main valve and cylinder-porting concept aimed at helping maintain drilling speed through a long service life.
- Working parts are protected with an effective lubrication approach, and the CP0069’s built-in oiler supports continuous lubrication.
- The “flat back” and streamlined shape are there for a reason: when you’re drilling in a quarry face, a trench, or a tight spot, handling matters.
Air supply recommendations (don’t starve it)
A sinker drill is only as good as the air you feed it. For best performance, build the air setup like you mean it:
- Run the correct pressure. Too low and it feels lazy; too high and you’re just accelerating wear.
- Use the right hose diameter for the run length so the CP0069 actually sees the air volume it needs.
- Use a water separator and a line oiler when conditions call for it—especially in humid/cold environments where moisture and icing can show up.
- Use proper rock drill oil and keep lubrication consistent to protect internal wear components.
Options and serviceability
The CP0069 is offered with two common chuck configurations (7/8″ x 4-1/4″ and 1″ x 4-1/4″), letting you match the tool to your existing steels/bits and job requirements. Wet drilling capability and water conversion components are also supported for dust control and compliance-focused sites.
Bottom line
If you’re shopping for a Chicago Pneumatic CP0069 Sinker Drill because you need dependable pneumatic drilling performance—2-1/2″ holes, depth capability around 20 feet, and the ruggedness to survive quarry and concrete environments—this is the workhorse-class choice. It’s built to drill hard, clean holes, stay controllable in the hands, and hold up where lighter tools tap out.
