Custom PVD Coating Tungsten Carbide Head for Deep Hole Gun Drill Our custom PVD (Physical Vapor Deposition) coating tungsten carbide
head for deep hole gun drill is a high-performance tooling solution
designed to meet the stringent requirements of deep hole drilling
operations. This specialized drill head combines the exceptional
hardness and wear resistance of tungsten carbide with the enhanced
surface properties provided by PVD coatings, making it an ideal
choice for a wide range of industrial applications. - The tungsten carbide core of the drill head is the foundation of
its cutting power. Tungsten carbide is renowned for its remarkable
hardness, which allows it to effortlessly cut through tough
materials such as hardened steels, stainless steels, and various
alloys. It exhibits excellent wear resistance, ensuring a long
service life. This durability significantly reduces the frequency
of tool replacements, minimizing production downtime and associated
costs. The carbide's high heat resistance is also crucial. During
the drilling process, a significant amount of heat is generated.
Tungsten carbide can effectively dissipate this heat, preventing
the drill head from overheating and maintaining the integrity of
the cutting edge. The specific grade of tungsten carbide used is
carefully selected based on the characteristics of the target
material, optimizing the drill head's performance for each
application.
- The microstructure of the tungsten carbide is engineered to provide
a balance between hardness and toughness, enabling the drill head
to withstand the rigors of deep hole drilling without chipping or
breaking.
- The PVD coating applied to the tungsten carbide head offers several
significant advantages. PVD coatings can enhance the surface
hardness of the drill head, further improving its wear resistance.
This is especially beneficial when drilling abrasive materials. The
coating also provides a low-friction surface, reducing the cutting
forces required and minimizing heat generation. Different PVD
coatings can be selected based on the specific drilling
application. For example, a TiN (Titanium Nitride) coating is known
for its golden color and excellent general-purpose wear resistance.
It can be used for a wide range of materials. TiAlN (Titanium
Aluminum Nitride) coatings, on the other hand, offer enhanced
high-temperature stability and are suitable for drilling materials
at elevated temperatures, such as in aerospace applications. The
thickness and composition of the PVD coating can be precisely
controlled to optimize the performance of the drill head.
- The PVD coating process is highly precise and environmentally
friendly, ensuring a consistent and reliable coating quality.
- The drill head is designed specifically for deep hole gun drill
applications. It features a long and slender profile with a central
coolant hole. The coolant, which can be a cutting oil or a
water-soluble emulsion, is pumped at high pressure through this
hole and directed to the cutting edges. The coolant serves multiple
essential functions. It cools the drill head and the workpiece,
preventing overheating and maintaining the integrity of the
tungsten carbide and the PVD coating. It also lubricates the
cutting process, reducing friction and facilitating chip
evacuation. The unique flute design of the gun drill head is
optimized to work in conjunction with the coolant system. The
flutes are shaped to guide the chips along with the coolant stream,
ensuring efficient removal of chips from the hole. This helps
prevent chip clogging, which is a common challenge in deep hole
drilling and can lead to tool breakage and poor hole quality. The
long length and rigidity of the gun drill head enable it to create
deep holes with high straightness and dimensional accuracy.
- The gun drill head design is engineered to maintain stability and
minimize vibration during drilling, further enhancing the quality
of the drilled holes and prolonging the life of the tool.
- We offer a high degree of customizability for our PVD coating
tungsten carbide head. The diameter of the drill head can be
precisely adjusted to meet specific hole size requirements,
typically ranging from a few millimeters to several centimeters.
The length of the drill head can also be customized to accommodate
different depth needs, with options available from relatively short
to extremely long lengths. Different flute geometries and PVD
coating types can be selected based on the target material and
drilling conditions. For example, a more aggressive flute geometry
may be used for softer materials, while a more refined geometry is
suitable for harder and more brittle materials. The shank design of
the drill head can be tailored to fit different machine tool
spindles, ensuring proper and secure attachment. This customization
allows the drill head to be optimized for a wide range of
applications, from small-scale precision machining to large-scale
industrial manufacturing.
- The ability to customize the drill head based on specific
requirements makes it a versatile tool for various industries,
including aerospace, automotive, machinery manufacturing, and more.

- In the aerospace industry, used for drilling deep holes in turbine
engine components, such as discs, shafts, and casings, for cooling
channels, fuel supply systems, and structural integrity. The high
precision and durability of the drill head are essential for these
critical applications.
- The automotive industry benefits from these drill heads in
manufacturing engine blocks, cylinder heads, and transmission
parts. They can drill deep holes for coolant passages, piston
sleeves, and other critical components, improving the overall
performance and reliability of the automotive systems.
- In the machinery manufacturing sector, ideal for drilling deep
holes in spindles, gears, housings, and other precision components.
The customizability of the drill head allows for the creation of
holes with the exact specifications required for proper assembly
and function, enhancing the performance of the machinery.
- Can also be applied in the oil and gas industry for drilling holes
in drill bits, downhole tools, and pipes, as well as in the
manufacturing of firearms and other defense-related equipment.
- Installation: The drill head is installed in a CNC machine or a dedicated deep
hole drilling machine following the manufacturer's instructions.
The shank is properly inserted into the spindle and secured using
the appropriate clamping mechanism. The coolant supply system is
connected to the drill head's coolant hole, ensuring a proper flow
of cutting fluid at the required pressure.
- Maintenance: Regular inspection of the drill head is necessary. Check for
signs of wear on the PVD coating, such as peeling or scratching,
and on the tungsten carbide, such as chipping or dulling. Inspect
the coolant hole for any blockages and clean it if required. The
drill head should be stored in a clean and dry environment to
prevent corrosion. Lubricate the shank and other moving parts as
recommended by the manufacturer. If the drill head shows
significant wear or damage, it should be replaced or reconditioned
to maintain optimal performance. Periodic calibration of the
machine and the drill head may also be required to ensure continued
precision and accuracy.
