Transforming machining standards with innovative ACE Spot Drill

In today’s fast-paced industrial landscape, where productivity and precision are paramount, Jimmore International Corp., through its innovative Nine9 Cutting Tool brand, continues to redefine machining excellence. The introduction of the ACE Spot Drill represents a leap forward in cutting tool technology, offering unmatched performance for spotting, countersinking, chamfering, and engraving applications. This next-generation tool is protected by multiple international patents, including United States Patent No: US 11,925,990 B2.

Enhanced Spotting for Precision Drilling 

Spotting creates a shallow hole to improve hole position accuracy, ensuring a better final product. The ACE Spot Drill excels in this domain with its innovative design, which increases drill feed rates, extends tool life, and enhances production efficiency. By ensuring that the centre of the drill is the first point of contact with the workpiece, it minimises drill walking and ensures accurate positioning. Its consistent performance guarantees uniform hole quality across applications, making it a preferred choice for machinists seeking precision and reliability.

Revolutionary Design and Features 

At the heart of the ACE Spot Drill’s superior performance lies its meticulously engineered design. The tool comprises a holder, an insert, and dual screws for secure fastening. These screws interact with screw holes on the holder and positioning holes on the insert, ensuring robust attachment. This design is further strengthened by two positioning posts and corresponding notches, which enhance alignment and fixation. The result is a simplified yet highly efficient structure with dual-directional fixation for enhanced durability and reliability. In the meanwhile, it also ensures the vibration free during the cutting.

The "ACE" in ACE Spot Drill encapsulates its core strengths:

• Accuracy: Design with symmetric 2-flute edges. It ensures precise hole diameters and spot angles for superior results. The ACE Spot Drill minimises lateral force, vibration, and burr formation, delivering better angle tolerance and consistent high-quality outcomes.
• Coolant: Features an advanced internal coolant design for optimal balance, heat dissipation, and lubrication. This improves tool performance and reduces wear and tear, making it an excellent choice for extended operations.
• Efficiency: Provides high rigidity, exceptional cutting performance, and ultra-long tool life. The tool is designed to save time and resources while maintaining top-tier results, making it an indispensable asset in modern machining environments.

Diverse Applications and Configurations

The ACE Spot Drill supports a wide range of machining needs, with insert diameters ranging from 6mm to 20mm. It caters to various spotting angles, including 60°, 90°, 120°, and 142°. This versatility ensures it meets the demands of different industries and applications, from aerospace to construction equipment manufacturing. The cylindrical shank and screw-fit cutter options add flexibility, making it ideal for diverse industrial applications. Furthermore, the holder’s compatibility with multiple insert grades and spot angles minimises tooling costs, providing an economically attractive solution for businesses striving for efficiency and cost-effectiveness.

Material-Specific Grades for Enhanced Performance

Three specialised insert grades make the ACE Spot Drill suitable for different materials:

• NC2057: Ideal for alloy steel and cast iron, offering excellent toughness and durability for demanding applications.
• NC5254: Optimised for stainless steel, ensuring smooth cutting and high resistance to wear.
• XP9000: Designed for non-ferrous materials like aluminium and titanium, as well as long-cutting chip metals. This grade delivers exceptional performance and efficiency in machining softer metals, reducing downtime and improving productivity.

Comprehensive Product Range

Nine9’s ACE Spot Drill series offers:

• Four spotting angles: 60°, 90°, 120°, and 142°, catering to diverse machining requirements.
• Three advanced coatings: Specifically engineered to handle a wide range of materials and applications.
• Six insert sizes: SI06, SI08, SI10, SI12, SI16, and SI20, allowing users to select the perfect fit for their needs.
• Dual clamping screw design: Ensures vibration-free cutting, enhancing the tool’s precision and longevity.
• Internal coolant-enabled holders: Provide superior lubrication and cooling, suitable for minimal quantity lubrication (MQL) setups. This ensures efficient chip removal and reduces heat build-up, enhancing the overall machining experience.

Real-World Impact: Case Studies

The ACE Spot Drill has earned accolades from leading manufacturers worldwide, demonstrating its superior capabilities in real-world applications:

• USA: A customer praised the tool’s durability, noting that "the tip is holding up remarkably well," a common pain point with traditional carbide spotting tools. The user also highlighted the superior surface finish of holes and efficient chip evacuation. The dual-point angle design ensures strength at the centre, reducing the risk of fractures, even in challenging conditions.
• Japan: A construction equipment manufacturer experienced transformative results when switching to the ACE Spot Drill for machining nitriding steel. This shift reduced cycle time by 12.5 hours and tool change time by 2.8 hours monthly, translating into significant cost savings. The manufacturer highlighted the tool’s consistent performance and its ability to handle high-demand workloads without compromising quality.

Another semiconductor manufacturer in Japan commended the tool for its productivity-enhancing capabilities. The internal lubrication design and dual-blade tip reduced cycle times, providing a competitive edge in a high-demand market. Their operations benefited from the ACE Spot Drill’s precise engineering, which ensured efficient and accurate outcomes.

User Endorsements and Industry Recognition

The ACE Spot Drill’s robust design and exceptional performance have earned positive feedback globally. Professionals across industries recommend it as an essential tool for improving machining efficiency and accuracy. Feedback from users in industrially developed markets like Japan and the USA highlights its game-changing potential. From small workshops to large-scale CNC manufacturing units, this tool is helping businesses achieve higher productivity and lower operational costs.

One customer remarked, "The surface finish on the holes is very nice, and the chips fall away easily. I am impressed with how well the tip holds up compared to other tools. The ACE Spot Drill truly sets a new benchmark in machining."
