CZ-F1M Standard Steel Body PDC Bit

High-Strength Steel Body PDC Drill Bit for Reliable Shallows and Water Well Construction

Product Overview & Description

The CZ-D1 Standard Steel Body PDC Bit is the ultimate workhorse for shallow-to-medium depth drilling applications. Precision-machined from high-grade structural alloy steel and treated with advanced heat technology, this bit features an incredibly robust core with exceptional mechanical impact resistance.

Designed for high-speed cutting in soft to medium formations, the CZ-D1 balances fast Rate of Penetration (ROP) with maximum operational stability. It serves as the most economical and efficient choice for international drilling contractors looking to optimize their daily operational costs.

Features & Outstanding Advantages

• High-Strength Monoblock Core: Machined via advanced multi-axis CNC from premium solid alloy steel, ensuring structural integrity and precise cutter placement under intense torque.

• Excellent ROP in Soft-Medium Strata: Optimized blade geometries and hydraulic flushing channels quickly clear rock cuttings, preventing bit balling and maximizing shearing efficiency.

• Strategic Hardfacing Protection: Critical erosion-prone areas are reinforced with standard tungsten carbide hardfacing to minimize abrasive wear during continuous rotation.

• Versatile Design & Connections: Available in 3-blade, 4-blade, or 5-blade configurations, seamlessly connecting to API standard drill strings.

Application Scope

The CZ-D1 is engineered specifically for soft, medium-soft, and non-abrasive medium formations, such as:

• Shale, mudstone, clay, and soft limestone.

• Standard sandstones and loose soil strata.

• Ideal Drilling Sectors: Water well drilling, shallow geo-technical exploration, agricultural wells, and environmental monitoring boreholes.

Frequently Asked Questions (FAQ)

Q1: When should I choose the CZ-D1 over the CZ-F1M bit?

A: If you are drilling mostly in clay, mudstone, shale, or soft limestone (common in standard water well projects), the CZ-D1 is your best choice because it offers incredible cutting speed at a lower cost. However, if your soil has heavy sand-gravel interbeds or abrasive quartz sandstone, you should upgrade to the CZ-F1M to prevent premature body erosion.

Q2: What cutter size is best for my CZ-D1 drill bit?

A: Generally, 1913 or 1613 cutters are ideal for softer, faster drilling because larger cutters take bigger bites out of the rock. 1308 cutters are better suited for medium formations where stability and smaller rock chips are preferred. We can customize the cutter layout based on your rig’s RPM and torque capacities.
