🛠️ Parts Breakdown by Equipment Component

Select your component category below to locate the precise part number needed for your scheduled maintenance or overhaul.

Chuck, Retainer & Fronthead Assembly (Nose Components)

The fronthead manages intense rotational friction and holds the drill steel in perfect alignment under heavy axial loads.

• Chuck Bushings & Sleeves: Precision-machined replacements for standard 7/8″ x 3-1/4″, 7/8″ x 4-1/4″, 1″ x 4-1/4″ hex shanks, as well as compact round and spline configurations.
• Beavertail Latch Retainers: Ultra-rugged latch mechanisms for the CP 0032A and CP 0069 series that increase collar contact area and eliminate steel slippage.
• Retainer Springs & Clips: High-tensile replacement wire springs for lightweight CP 0009 and CP 0022 utility drills.

Rifle Bar, Rifle Nut & Rotation Components

The rotation train converts the piston’s linear reciprocating energy into synchronized, high-torque left-hand rotation.

• Rifle Bars & Rifle Nuts: Splined internal shafts and matching bronze nuts that dictate the rotational rhythm of the drill steel.
• Rotation Pawls & Springs: Directional ratchet pawls and heavy-duty springs that lock the mechanism into a strict, non-slip rotational cycle.
• Fluted Drilling Pistons: Dual-action beaters machined with internal splines to seamlessly engage the rifle bar while striking the steel shank.

Valve Blocks, Throttles & Blower Mechanisms

Fix slow rotation speeds, poor hole-flushing capabilities, or startup failures with genuine air-train components.

• Blower Valve Levers & Seals: Restores the critical high-pressure “air-blast” flushing function needed to force sludge and cuttings out of deep vertical holes.
• Ratcheting Throttle Valves: Multi-position control valves that provide smooth, progressive acceleration for accurate hole “collaring.”
• Simplate & Ring Valve Triggers: Complete valve box housings, discs, and caps engineered for precise, high-frequency percussive timing.

Side Rods, Handle Grips & Mufflers

Ensure structural tool integrity, maintain operator control, and satisfy localized environmental safety thresholds.

• High-Tensile Side Rods & Nuts: The longitudinal structural bolts that clamp the entire rock drill assembly together under immense pressure.
• Integral Oiler Chambers: Replacement handle reservoirs and adjusting screws that meter rock drill oil into the incoming air stream.
• Polyurethane Muffler Jackets: Impact-resistant, sound-suppressing wrappers engineered specifically for silenced (S/AS) variations.

🔧 Pro-Tip: Protect Your Rotation Train and Structural Bolts

Master the Side Rod Tensioning: Because handheld sinker drills perform a dual percussive and rotational function, they are held together by two long external Side Rods. If these side rods are tensioned unevenly or allowed to loosen even slightly during a shift, the internal alignment of the rifle bar, cylinder, and valve box shifts. This causes massive internal air bypass, stalls the rotation train, and can instantly crack the expensive forged backhead. Always tighten side rod nuts evenly as a pair, and never operate a rock drill without ensuring your inline oilers are supplying a constant mist of SAE #10 rock drill oil. A dry drill will burn up the bronze rifle nut in less than a single production shift, completely seizing your rotation.

Need a Complete Replacement Sinker or Rock Drill?

Don’t let missing components halt production on your quarry or utility contract. If a complete mechanical overhaul isn’t cost-effective, we supply the full lineup of professional-grade pneumatic drills.

• CP 0009 / CP 0014 Series (Compact Class): Nimble 9 to 15 lb. dual-action utility hammers that convert from a rock drill to a pure chipping hammer with the push of a button.
• CP 0022 (30 Lb. Utility Sinker): The ideal lightweight utility drill for scaffolding work, limited air supplies, and drilling anchor holes up to 8 feet deep.
• CP 0032A / CP 0032AS (45-50 Lb. Standard): The industry-standard construction and bench mining workhorse, featuring an independent blower lever and available muffled (AS) configurations.
• CP 0069 (60 Lb. Heavy Production): Maximum handheld brute force engineered to clear deep mass-production blast holes up to 20 feet deep in solid granite.
