Which button shape is best for the hard granite found in the Western Province?

For extremely hard and abrasive rock like granite, we recommend Spherical (Domed) buttons. While they drill slightly slower than ballistic shapes, they offer 30-50% more durability and are much less likely to fracture under high-impact pressure.

How often should I inspect or regrind my bits on a Saudi site?

In highly abrasive formations, you should inspect your bits every 50 to 100 meters. Regrinding the buttons as soon as they show a "flat" surface (about 1/3 of the button diameter) will significantly extend the life of the bit and maintain high penetration rates.

Can I use a Hatoon DTH bit with a different brand of hammer?

Absolutely. As long as the shank type (e.g., DHD350, QL50, SD6) matches your hammer’s internal drive, our bits will perform perfectly. We manufacture bits to international standard tolerances to ensure universal compatibility across all major rigs in the KSA.

DTH Bits: Precision Cutting Edges for Saudi Arabia's Hard Rock

The DTH (Down-The-Hole) Bit is the primary interface between your drilling rig and the earth, responsible for the actual crushing and removal of rock. At Hatoon Machinery, we provide premium DTH bits forged from high-grade alloy steel and fitted with superior tungsten carbide inserts. Engineered to withstand the extreme percussive forces of our Rocky Series hammers, these bits are optimized for the diverse geology of the Kingdom, from the abrasive sandstone of the Empty Quarter to the high-strength granite in NEOM. Our bits ensure straighter holes, faster penetration, and a longer service life in the most demanding Saudi environments.

Our DTH Bit Design Portfolio

Face Design	Key Advantage	Best Application
Concave Face	Excellent hole straightness and flushing.	Medium-hard to hard rock (standard KSA sites).
Flat Face	Maximum durability and wear resistance.	Extremely hard and abrasive rock (Granite/Basalt).
Convex Face	Highest penetration rates in soft rock.	Shale, limestone, and non-abrasive formations.
Drop Center	Superior centering for deep-hole accuracy.	Soft to medium rock with strict deviation limits.

Why Choose Hatoon DTH Bits?

Precision drilling in the Middle East requires more than just a sharp edge; it requires a bit that can handle intense thermal loads and abrasive wear.

Premium Tungsten Carbide: We use high-density carbide buttons (Spherical, Ballistic, or Parabolic) that maintain their edge longer, reducing the frequency of regrinding on busy Riyadh job sites.
Superior Flushing: Our bits feature optimized air holes and chip grooves to ensure that cuttings are cleared instantly. This prevents "re-drilling" of dust, which is a major cause of bit wear in dry Saudi climates.
Heat-Treated Alloy Body: The bit body is case-hardened to resist "body wash" from high-velocity cuttings, ensuring the buttons stay securely seated even in deep Jeddah piling projects.
Local Inventory: We maintain a massive stock of popular shank types (DHD, QL, SD, Mission) in our Riyadh and Jeddah hubs, ready for same-day or next-day delivery to your site.
