RH 658 L Pneumatic Hand Held Surface Rock Drill by Atlas Copco

Atlas Copco RH 658 L Pneumatic Hand Held Surface Rock Drill

The Atlas Copco RH 658 L is a heavy-duty pneumatic hand held surface rock drill built for production drilling, quarry work, dimension stone applications, blast hole drilling, secondary drilling, and other demanding hard-rock jobs where a smaller hand drill will not cut it. This model is the 7/8" x 4-1/4" hex chuck version, SKU 8311030286, with a 123 CFM air requirement and a 53 lb operating weight as listed for this configured product.

Designed as part of Atlas Copco’s RH pneumatic rock drill lineup, the RH 658 L is slightly heavier and more powerful than the smaller RH models, giving it the added hitting force needed for deeper drilling in tough material. Atlas Copco describes the RH range as a proven surface drilling platform tied to the long-running “Swedish Method,” with the RH 658 L positioned for hard rock and high-output surface drilling.

Built for Hard Rock Drilling

The RH 658 L is made for operators who need a dependable pneumatic rock drill for tough production environments. It uses compressed air to drive a strong percussive action while maintaining rotation through the drill steel, helping the bit break and clear material efficiently. With a 29 mm to 40 mm hole range, this drill is well suited for common quarry, construction, and dimension stone drilling tasks where control, impact power, and steady penetration matter.

Atlas Copco lists the RH 658 L at 2,040 blows per minute, 215 rpm, and a penetration rate of 16.7 inches per minute under published test conditions. Those numbers give this drill the combination of impact rate, rotation, and feed performance needed for drilling in granite and other hard rock materials.

Built-In Air Flushing for Cleaner Holes

One of the RH 658 L’s most useful features is built-in air flushing. A direct flow of compressed air through the drill steel helps remove drill cuttings from the hole while drilling. That matters because cleaner holes reduce the chance of jamming, improve drilling consistency, and help the operator keep the job moving without constant stops to clear the hole manually. Atlas Copco specifically highlights built-in air flushing across the RH models as a way to remove chippings and prevent jamming.

For quarry crews, contractors, and stone operations, that flushing capability is not just a convenience. It directly supports better productivity in deeper or harder holes where cuttings can quickly slow the drill down. Atlas Copco’s handheld tools facts book also lists built-in air flushing and extra flushing for quick, efficient hole cleaning among the features of the medium and heavy pneumatic rock drill group that includes the RH 658 L.

Best Applications for the RH 658 L

The RH 658 L is intended for serious drilling work, not light-duty shop use. It is a strong fit for:

1. Production drilling in quarry operations
2. Dimension stone drilling
3. Secondary drilling
4. Bench drilling
5. Smooth blast drilling
6. Hard rock drilling on construction sites
7. Drilling where built-in air flushing is needed to keep holes cleaner

Atlas Copco lists the RH 658 L for production drilling in quarry and dimension stone industry, while competitor listings also describe the RH machines as suitable for bench, secondary, and smooth blast drilling.

Why Buy the Atlas Copco RH 658 L

The RH 658 L gives contractors and quarry operators a proven pneumatic drilling platform with the air consumption, weight, impact rate, and rotation speed needed for demanding rock drilling. It is compact enough to remain hand held, but powerful enough for harder drilling work where lighter surface drills may not have the output or depth capability needed.

If you need a pneumatic hand held surface rock drill with a 7/8" x 4-1/4" chuck, 123 CFM air requirement, built-in air flushing, and Atlas Copco’s established RH drilling design, the RH 658 L is a strong choice for hard rock, quarry, and dimension stone applications.
