Why Choose Our Hole-making Tools?
As the leading CNC hole making tools supplier in China, JINOO has self-developed a wide range of carbide hole making tools series to suit various requirements for machining different workpiece materials.

Solid Carbide Construction
JINOO’s hole-making tools are manufactured from 0.4μm ultra-fine grain carbide, which means their uniform binder distribution.

Oerlikon Coating Technology
Our hole-making tools are all combined with multilayer PVD coatings, featuring evenly distributed thickness and consistent edge coverage.

Optional Internal Coolant Design
Our high-performance hole-making tools are typically designed with axial internal coolant channels.

Cutting Edge Preparation
Precision-honed cutting edges are commonly treated with a controlled edge radius and micro-chamfer geometry design.

Optimized Flute Geometry
Our hole-making tools are designed with helical flute profiles and variable rake angles to promote the chip flow .

Rigid Structure Design
All the hole-making tools are engineered with a robust tool structure, delivering continuous cross-sectional support.
Hole-Making Tool Geometry Breakdown
1.Solid Carbide Construction for Higher Rigidity
Our hole-making tools are all manufactured from 0.4μm ultra-micro grain carbide with sufficient cobalt content, which balances hardness and transverse rupture strength.
2.Oerlikon Coating Technology for Longer Tool Life
Oerlikon high-performance PVD coatings are designed with a multilayer nanostructure, and the coating thickness is commonly from 2 to 5μm to deliver higher wear resistance.
3.Optional Internal Coolant for Higher Cooling Efficiency
Designed with the trough-coolant channels, enhanced cooling efficiency can be achieved with custom drilling depths from 3×D to 30×D.
4.Cutting Edge Preparation for Enhanced Edge Integrity
Precisely-honed cutting edges can minimize edge chipping with tight edge radii controlled from 10 to 30μm.
5.Optimized Flute Geometry for Efficient Chip Evacuation
Specialized flutes feature variable helix and polished flutes, improving the smooth chip flow with high drilling stability.
6.Rigid Structure Design for Superior Hole Accuracy
The reinforced core with cross-sectional geometry can enhance the tool stiffness, further enhancing the dimensional accuracy in deep-hole machining.

FAQ about Hole-Making Tools
What’s the delivery time for JINOO’s Hole-Making Tools?
The delivery time of our hole-making tools is typically within 3-5 days when it comes to standard tools in stock, while it should be confirmed after you contact our sales team if you need custom tools.
Do you provide customized services of hole-making tools?
Of course! We furnish non-standard customization beyond standard sizes according to your personalized needs. Factors such as materials, diameter, flute length, and coating choice of JINOO’s Hole-Making Tools can all be modified to meet your exacting requirements. You can contact our professional sales team with your demanding requirements about the specific tooling configurations, and we will provide you with cutting-edge tooling solutions to ensure an exceptional user experience.
What is your MOQ (Minimum Order Quantity) of hole-making tools?
For our standard size of hole-making tools, we have a minimum order quantity of 5 pieces. Beyond that, if you want JINOO to customize tools for you, there’s generally no minimum order quantity for non-standard tools, and even a small order can be accepted.
Choosing appropriate Hole-Making Tools depends on your workpiece materials, the equipment used, machining conditions, hole diameters, tolerance requirements, and production volume.
Here are some quick guides and tips for you:
- Suppose you are looking for general-purpose machining for crankshafts, wheel hubs, aerospace, automotive applications, etc. Standard drilling tools like carbide or modular drills can be practical.
- For massive-volume operations, Indexable Drills can be a great choice. They can make quick changes to save time, extend the tool lifespan, and lower per-part costs.
- Combining Step Drills and Countersink/ Counterbore Tools can increase machining efficiency if you require countersinks or step holes.
- For clients with stringent requirements for fine surface finishes and tight tolerances, consider the Reamers and Deep Hole Drills, which improve machining efficiency and hole accuracy while enhancing chip extraction, drilling efficiency, and hole quality.
- Thread Mills and Taps can help you meet the hole accuracy requirements for threaded holes.
- Do not worry if you are confused about which types of hole-making tools are most suitable for you. Our technical department will offer application-specific consulting, test-cutting support, and further tool improvement strategies for your current products to help you maximize production efficiency and reduce production costs for Hole-Making Tools.
JINOO’s Hole-Making Tools can be applied in many industries, including but not limited to:
- Electronics and Precision Parts: Connectors, Enclosures, and other small parts, etc.
- Energy: Wind Turbine Hubs, oil & gas components, and power generation parts, etc.
- Heavy Equipment: Hydraulic parts, construction machinery, Mining machinery, etc.
- Suitable for CNC Machining Centers, Turning Machines, Automated Production Lines, etc.
Drilling refers to using drill bits to drill holes from solid workpiece materials, while boring is used for enlarging and finishing pre-drilled holes. Drilling tends to enhance the production efficiency, while boring focuses on improving the straightness and roundness of holes. Drilling is the first step in CNC machining, and boring is suitable for application scenarios where tight tolerances and surface finishes are required.
