Engineered to withstand the demanding thermal and mechanical stress profiles found in Jakarta’s heavy metalworking and electronics industries.
The industrial landscape of the Greater Jakarta Area (Jabodetabek)—encompassing key clusters such as Cikarang, Karawang, Bekasi, and Tangerang—represents the absolute core of Indonesia's modern manufacturing power. The concentration of automotive assembly plants (including Toyota, Honda, Hyundai, and Wuling), consumer electronics assembly networks, and heavy machinery fabricators creates a massive local demand for high-end metalworking solutions. In these competitive environments, machining cycle times and tool replacement rates directly impact operating margins.
Traditional High-Speed Steel (HSS) and low-grade carbide tools are proving increasingly inadequate for modern CNC operations. As Indonesian manufacturers upgrade their shop floors with advanced 5-axis vertical machining centers (VMCs), the demand has shifted dramatically toward ultra-fine micro-grain solid carbide drills. These tools can operate at cutting speeds (Vc) and feed rates (fn) that are three to five times higher than conventional options. For the Jakarta market, where industrial land costs and labor wages continue to rise, optimizing feed rates via high-performance tooling is the most direct path to cost-per-part reduction.
At Suzhou Tier Tool Co., Ltd., our engineering methodology treats drill bit design as an exact science. A solid carbide drill bit is only as good as its substrate formulation and geometric accuracy. We utilize premium sub-micron and ultra-fine grain tungsten carbide substrates with cobalt contents ranging between 8% and 12%. This structural balance achieves an optimized equilibrium between hardness (HV30) and transverse rupture strength (TRS), preventing premature micro-chipping on the cutting edges under fluctuating mechanical loads.
Furthermore, our tool geometries are tailored for specific chip evacuation profiles. Standard drill bits often suffer from chip packing in deep-hole applications, particularly when machining sticky materials like low-carbon steels or die-cast aluminum alloys (such as ADC12). Our designs utilize variable helix angles, polished chip flutes, and specialized point geometries (such as 140° split points with optimized web thinning). These features minimize axial forces, reduce heat generation at the shear zone, and prevent thermal deformation of both the workpiece and the tool.
Established in 2008, Suzhou Tier Tool Co., Ltd. is a national high-tech enterprise specializing in the design, manufacturing, and technical support of precision solid carbide cutting tools. Over the course of nearly two decades, Tier Tool has been deeply committed to the precision machining industry, focusing on delivering high-performance, high-efficiency cutting solutions for hole-making and metalworking applications worldwide. Through continuous technological innovation and manufacturing excellence, the company has earned the trust of customers across a wide range of industries globally, including automotive, aerospace, and electronics.
Quality is the foundation of Tier Tool's long-term success. We adhere to the strict principle of "Quality First, Continuous Improvement", implementing rigorous quality control procedures throughout the entire production cycle. From raw material selection and incoming inspection to final product verification, every tool undergoes comprehensive quality checks using advanced optical measurement systems. This ensures it meets strict dimensional, geometrical, and performance requirements. By continuously optimizing our manufacturing and inspection processes, we deliver products that provide exceptional accuracy, reliability, and consistency in real-world machining applications.
For the automotive manufacturing clusters in Karawang and Bekasi, we provide high-performance internal coolant twist drills designed for engine block and cylinder head machining. These tools withstand high-temperature environments and ensure outstanding dimensional stability, even when processing challenging aluminum-silicon alloys or cast iron. The internal coolant channels deliver pressurized coolant directly to the cutting zone, flushing out chips instantly and reducing cutting temperatures.
In the electronics and semiconductor sectors located in Tangerang and Bekasi, precision micro-drilling is essential. Our ultra-fine grain tungsten carbide micro-drills (down to 0.4mm and 0.7mm diameters) are coated with specialized TiAlN or diamond-like coatings, ensuring clean, burr-free holes in high-density PCBs and mobile device components. The high rigidity of our micro-drills prevents tool deflection, achieving tight positional tolerances and long tool life on automated SMT production lines.

As manufacturing moves toward Industry 4.0, the tooling industry is experiencing rapid innovation. Suzhou Tier Tool Co., Ltd. is actively investing in research and development to align with these global changes. Our technology roadmap focuses on three main developments:
For procurement professionals in Jakarta, shipping lead times, customs clearance at Tanjung Priok, and consistent supply chain management are critical factors alongside initial tool costs. To minimize downtime risk, Suzhou Tier Tool has optimized its export logistics systems to support the Greater Jakarta region.
Through partnerships with leading global logistics providers and optimized customs declaration paths, we offer reliable lead times for both standard stock and custom-designed tools. By maintaining high raw material inventories of premium carbide rods, we buffer against global supply chain volatility, providing stable pricing structures and dependable production schedules for our Indonesian industrial partners.

Solid carbide offers significantly higher red hardness and compressive strength compared to high-speed steel. This allows CNC machinery to operate at speeds and feeds that are 3 to 5 times faster. This shift reduces per-part cycle times, improves hole surface finishes (eliminating secondary reaming steps), and extends tool life, leading to a lower overall cost-per-hole in high-volume production environments.
High humidity can accelerate oxidation on uncoated steel components. However, our high-grade TiAlN (Titanium Aluminum Nitride) and CVD diamond coatings are highly inert and resistant to chemical corrosion. Additionally, all Suzhou Tier Tool products undergo an anti-rust treatment and are sealed in moisture-resistant packaging, ensuring they remain in pristine condition during transit and storage in tropical climates.
For standard catalog tools in stock, shipment processing takes 2–4 business days, with air freight delivery taking 5–7 days to Jakarta. Custom-designed solid carbide tools require 2–3 weeks for design, precision grinding, coating, and inspection, followed by air or sea freight depending on order volume and urgency.
Internal coolant drills utilize oil holes that run through the tool body. This design allows pressurized cutting fluid to reach the cutting interface directly. This configuration flushes chips out of the hole, controls thermal expansion, prevents chip packing, and ensures stable operations at drilling depths beyond 3D (three times the tool diameter).
Yes. Our tools are manufactured according to international standards (including DIN, ISO, and JIS specifications) using h6 shank tolerances. This high precision ensures compatibility with high-performance tool holding systems (such as hydraulic, shrink-fit, and ER collet chucks) on Japanese CNC machines like Yamazaki Mazak, Fanuc, Okuma, and Makino.
We require the specific workpiece material (e.g., ADC12 aluminum, AISI 1045 steel), target machining dimensions (diameters, steps, and angles), coolant type, and machine spindle speed/feed capability. Our engineering team can work directly from 2D drawings or 3D CAD step files to optimize tool geometry.
Our Quality Policy is built on complete process control. We utilize high-precision Swiss-made Rollomatic and German-made Walter CNC tool grinders, coupled with high-end Zoller genius inspection machines. Every batch is traceable from the raw material carbide rod to the final packaging, ensuring consistent tolerances across all production runs.
Yes. We work closely with local industrial distributors and technical engineers in the Jakarta region. We provide online engineering support, cutting parameter recommendations, and on-site testing support for large-scale production runs to optimize machining parameters directly on your shop floor.
