When discussing the cost of a DN130 diamond drill bit, it is impossible to provide a single fixed figure, as prices vary dramatically across different application scenarios, brand tiers, manufacturing technologies, and product configurations. A DN130 diamond drill bit—referring to a drill bit with a nominal diameter of 130 millimeters—finds use in diverse fields ranging from household tile drilling and construction concrete coring to industrial mineral exploration, oil and gas well drilling, and even deep geothermal drilling. Each field imposes unique requirements on the drill bit’s diamond quality, matrix material, structural design, and wear resistance, directly driving price differences that can span from as low as a few US dollars to tens of thousands of dollars. To comprehensively address the question of “how much a DN130 diamond drill bit costs,” this article will systematically analyze price ranges, core influencing factors, and detailed introductions to mainstream brands and models, providing readers with a holistic and in-depth understanding.

The application scenario is the most decisive factor affecting the price of a DN130 diamond drill bit. Different working conditions demand varying levels of performance, and manufacturers tailor their products accordingly, leading to distinct pricing strategies. Below is a detailed breakdown of price ranges across key application fields, supported by market data and supplier information.

In scenarios such as home renovation, bathroom and kitchen tile installation, or small-scale stone processing, DN130 diamond drill bits are typically designed as small-diameter core bits or hole saws, emphasizing portability, ease of use, and cost-effectiveness. These bits usually adopt vacuum brazed or electroplated diamond technology, with relatively low diamond concentration and matrix hardness. According to data from Alibaba.com and specialized tool suppliers, the price of such DN130 diamond drill bits generally ranges from US$1.00 to US$39.00 per unit. For example, the Crawnedeagle CDB-VB vacuum brazed diamond core drill bit (130mm), suitable for porcelain tiles and marble, is priced between US$3.00 and US$3.70 per piece with a minimum order quantity (MOQ) of 10 pieces, and it supports both dry and wet drilling. Another option, the Perfactool 6-130mm M14 thread dry brazed diamond core bit, targets ceramic and granite drilling, with prices ranging from US$2.03 to US$20.02 per set, depending on diamond grain size and segment thickness. For entry-level products aimed at DIY enthusiasts, such as the diamond-coated hole saw kits available on Alibaba, individual 130mm bits can be as cheap as US$0.46, though these often come with shorter warranties (1 month or none) and are prone to rapid wear under continuous use.

In construction projects like bridge maintenance, building structural testing, or concrete pipeline installation, DN130 diamond drill bits are required to penetrate reinforced concrete, masonry, or asphalt—materials with high hardness and abrasiveness. These bits typically feature sintered diamond segments, thicker barrels, and standardized connections (e.g., M41 or 1-1/4 inch threads) to match professional core drilling machines. Prices in this category are significantly higher than household-grade products, ranging from US$50.00 to US$650.00 per unit. Hilti, a leading brand in construction tools, offers the SPX-L hand-held core bit series, which, while not explicitly listing a 130mm model, has 1-inch (25.4mm) variants starting at US$106.00, and industry estimates suggest a 130mm SPX-L bit—optimized for <2.5kW tools and wet drilling in concrete—would cost between US$200.00 and US$300.00. Karl Dahm’s Drill Master wet core drill bit (art. no. 50438) is a professional-grade 130mm option priced around US$37.00 to US$39.00, featuring a 7.5mm segment height, 1/2-inch external thread, and compatibility with both stand and handheld drills, making it ideal for precise edge drilling in granite and ceramic tiles without chipping. Domestic Chinese brands like Yue Rong and Deyi offer more affordable alternatives, with 130mm wet-cutting masonry core bits priced between US$5.59 and US$16.00, though these often require higher MOQs (20+ pieces) and have shorter service lives compared to international brands.

Geological exploration and mining demand DN130 diamond drill bits that can withstand complex formations, including hard granite, siliceous rock, and fractured strata. These bits are usually of the impregnated or PDC (Polycrystalline Diamond Compact) type, with high diamond concentration (50%-70% volume fraction) and wear-resistant matrices (HRC 25-35). Prices here range from US$500.00 to US$1,500.00 per unit. JC Drill’s HQ NQ 130mm diamond core drill bit (model: Bit-NQ-C6-YC-10#) is a representative product for mineral exploration, featuring a 30mm crown height, T6 series matrix, and uniformly distributed synthetic diamond grains. Priced between US$800.00 and US$1,100.00, it is designed for deep core sampling and offers improved stability with taller crowns to reduce vibration during drilling. Shandong Yikuang Drilling Technology’s Φ130mm diamond directional drilling bit, tailored for coal mine gas drainage and water exploration holes, uses high-impact-resistance PDC cutters and a sintered matrix, priced at approximately US$70.00 to US$100.00 (converted from ¥500.00) with the advantage of long service life and minimal diameter reduction compared to steel-body bits. For hard rock formations, Zhuzhou Diamond’s 130-type low-air-pressure DTH (Down-the-Hole) drill bit, made of high-quality cemented carbide, costs around US$70.00 (¥490.00) and is widely used in iron ore mining for its strong penetration capability.

In oil and gas exploration, especially in ultra-deep wells (e.g., 8,000+ meters) or high-temperature/high-pressure formations, DN130 diamond drill bits (often PDC or TCI tricone types) must resist extreme temperatures (>190°C) and corrosive drilling fluids. These bits integrate advanced technologies such as diamond coating, sensor integration, and optimized hydraulics, leading to prices ranging from US$2,000.00 to US$25,000.00 or more per unit. Boart Longyear’s 920609 DTH bit is a 130mm (5-1/8 inch) model designed for oilfield applications, featuring a QLX 4T/TD 40 shank, 8/15 flushing holes, and a concave spherical face profile. While exact pricing is not publicly disclosed, similar 127mm (5-inch) models from the brand cost between US$1,680.00 and US$1,880.00, suggesting the 130mm variant would exceed US$2,000.00. Deshi Co., Ltd.’s φ130 series ultra-high-temperature PDC drill bit, which was used in China’s second 10,000-meter deep well (Xin’an 1 Well), withstood井底 temperatures over 190°C and achieved a single-run footage record of 1,207 meters. As a custom high-end product, its price is estimated at US$15,000.00 to US$25,000.00, reflecting its performance in extreme conditions. Sandvik’s 130mm PDC drill bits for oil and gas wells, though lacking specific model details, fall within the US$450.00 to US$1,000.00 range according to market snapshots, with premium variants for deep formations exceeding US$5,000.00.

Beyond application scenarios, the price of a DN130 diamond drill bit is shaped by a complex interplay of technical and market factors. Understanding these factors helps buyers interpret price differences and select products that balance cost and performance.

Diamond is the core cutting component, and its quality directly determines the bit’s efficiency and lifespan. Industrial diamonds are categorized into synthetic and natural types: synthetic diamonds (e.g., CVD or HPHT) dominate the market due to controlled quality and lower costs, while natural diamonds are reserved for ultra-hard formations but are rarely used in 130mm bits due to high expenses. Within synthetic diamonds, grain size (40/50 mesh for general use, 20/30 mesh for hard rock) and purity (99.9% vs. 95%) affect pricing. A DN130 bit using 40/50 mesh synthetic diamonds with 55% volume concentration costs 30%-50% more than one with 30% concentration and 80/100 mesh grains. For example, the Crawnedeagle CDB-VB bit uses premium diamond powder with vacuum brazing, increasing its price by 20% compared to electroplated bits with lower-purity diamonds.

The matrix (the metal bond holding diamonds) must balance hardness and wear resistance to ensure diamonds are exposed at a steady rate. Common matrix materials include cobalt-based alloys (for hard formations) and iron-copper alloys (for soft formations). Cobalt-based matrices cost 2-3 times more than iron-copper ones due to cobalt’s high price and superior bonding strength. Manufacturing processes further widen price gaps: vacuum brazed bits (used for tiles/glass) cost US$1-$30 because the process is simple and uses less diamond, while sintered bits (for concrete/rock) require high-temperature/pressure sintering, costing US$50-$1,500. Impregnated bits for exploration, which embed diamonds deep within the matrix, are even more expensive due to precise diamond distribution requirements.

Brand reputation and technological investment significantly impact pricing. International premium brands (Hilti, Boart Longyear, Sandvik) invest heavily in R&D, quality control, and after-sales service, leading to prices 2-5 times higher than domestic or generic brands. Hilti’s SPX-L series, for instance, incorporates Equidist Technology (precisely positioned diamonds) and compatibility with its proprietary drills, justifying its US$200+ price tag compared to US$50-$100 domestic alternatives. Boart Longyear’s 920609 bit features optimized flushing hole design to reduce clogging, a key innovation for oilfield efficiency that adds to its cost. Domestic Chinese brands like Zhuzhou Diamond and Shandong Yikuang offer competitive prices by leveraging lower labor and material costs, though their products may lack advanced features like sensor integration or ultra-high-temperature resistance.

The global diamond drill bit market is influenced by raw material prices (synthetic diamonds, cobalt, tungsten carbide) and industry demand. In 2024-2025, the price of synthetic diamonds rose 15% due to increased demand from the mining and construction sectors, pushing up drill bit costs by 10%-20%. The oil and gas industry’s recovery post-2023 has driven demand for high-performance PDC bits, with prices for 130mm oilfield bits increasing by 25% year-over-year. Conversely, oversupply in the household tool segment has led to stable or slightly declining prices for low-end 130mm tile drill bits. Additionally, MOQs affect unit prices: bulk orders (100+ pieces) from suppliers like Alibaba can reduce costs by 10%-30%, while single-piece purchases for emergencies incur premium prices.
