Fully Modular, Fully Customizable
You’re not locked into one shape or nozzle. Hirt Line is a true modular system, meaning you can build it to fit just about any machine configuration.

Choose from a variety of:

• Line sizes:
  • Type 0 (1⁄8″) – internal passage ≈ 3.2 mm (0.126″)
  • Type 1 (1⁄4″) – internal passage ≈ 5.8 mm (0.228″)
  • Type 2 (1⁄2″) – internal passage ≈ 11 mm (0.433″)
  • Type 3 (3⁄4″) – internal passage ≈ 19 mm (0.748″)
• Nozzles: round, flat, or even multi-nozzle manifolds
• Mounts and bases: threaded, magnetic, or machine-specific adapters
• Rigid or flexible segments depending on what you’re trying to reach

Want to run multiple coolant lines from one port? Easy. Want to send high-pressure coolant to a deep-pocketed feature without risking tool breakage? Done. The Hirt Line system gives you total control.

Where Hirt Line Really Shines
While you can use Hirt Line for general machining, it really stands out in high-pressure, tight-tolerance, or multi-axis environments— which is where most all other systems fall short.

Some ideal applications include:

• Swiss-type lathes and multi-axis turning centers where nozzle position matters
• High-pressure coolant setups where traditional nozzles leak or fail
• Toolroom machines that need fast, repeatable coolant changes
• Robotic cell integration where coolant must be locked-in and reliable
• Additive + subtractive hybrid machines where heat control is critical

If you’re running custom geometries, special long length tools, deep pockets, complex cycles, or automated production, Hirt Line helps you eliminate one of the most overlooked variables in machining: consistent and controlled coolant delivery.

Why Shops Make the Switch
Here’s what shop managers love most about Hirt Line:

• No adjustments during a run—it stays where you set it
• Lasts for years, not months
• No leaks, even under high pressure
• Looks professional and impresses customers and auditors alike
• Speeds up setups, especially when switching between parts or fixtures

And here's the bonus: It's also reusable. When you move machines or retool your process, you can break down the system and rebuild it to fit your new setup. That’s long-term value built right in.

Tool coatings play a critical role in optimizing performance, extending tool life, and reducing overall operating costs in most all cutting tool applications today. Rocky Mountain Blue™ nACo® Coating is a next-generation nanocomposite (NC) coating designed to push the boundaries of high-performance drilling and machining. Manufactured using a Platit-exclusive LARC (Lateral Rotating Cathode) coating process, this advanced multilayer coating system enhances wear resistance, thermal stability, and friction reduction.

Understanding Nanocomposite Coatings (nACo®)
The term nACo® refers to a nanocomposite coating structure, where ultra-hard nanocrystalline grains (such as TiN, TiAlN, or AlCrN) are embedded in an amorphous silicon nitride (SiN) matrix. This structure prevents grain growth and enhances hardness by creating a fine nanoscale grain distribution.

A useful analogy is wet sand versus dry sand—where dry sand shifts underfoot, but wet sand offers greater resistance due to the spaces between grains being filled with water. Similarly, the SiN matrix locks nanocrystals in place, increasing surface hardness and durability.

Key Features of Rocky Mountain Blue™ nACo® Coating

• Extreme Hardness: The nanocomposite structure significantly increases coating hardness, enhancing tool longevity and wear resistance.
• Superior Thermal Stability: Maintains structural integrity at temperatures up to 1200°C, making it ideal for high-speed and dry machining applications.
• Low Friction Coefficient: Reduces heat generation and tool wear, contributing to smoother and more efficient cutting performance.
• Proven Tool Life Enhancement: RMT (Rocky Mountain Twist) testing demonstrated a 40% increase in tool lifecompared to uncoated tools when dry drilling.
• Optimized for Steel and Stainless Steel: Delivers better performance than traditional TiAlN coatings, increasing feeds and speeds while maintaining or improving tool life.

Triple-Layer Multiphase Coating Architecture
Rocky Mountain Blue™ nACo® utilizes a triple-layer coating system, strategically engineered for enhanced adhesion, hardness, and thermal resistance:

1. TiN (Titanium Nitride) Base Layer
   • Improves adhesion to the substrate
   • Enhances wear resistance
2. TiAlN (Titanium Aluminum Nitride) Middle Layer
   • Provides high hardness
   • Reduces friction for extended tool life
3. TiAlN/SiN (Silicon Nitride) Top Layer
   • Acts as a temperature-resistant ceramic barrier
   • Promotes nano-scale structural reinforcement
   • Ensures stability in extreme heat conditions

These three layers work together to create a 10µm thick multilayer hard coating—one-fifth the thickness of a human hair (50µm), yet offering immense performance benefits.

Advantages Over Traditional Coatings
While TiAlN and AlTi(Si)N coatings are common in high-performance cutting tools, Rocky Mountain Blue™ nACo® Coating outperforms them in several critical areas:

With its ability to support higher speeds and feeds while maintaining a lower cost per hole, nACo® provides a substantial return on investment (ROI) for manufacturers seeking improved productivity.

Engineered for High-Speed Steel (HSS) and Cobalt (HSCO) Tools
While many nanocomposite coatings are reserved for carbide tooling, Rocky Mountain Blue™ delivers unprecedented performance enhancements on HSS and HSCO tools. This is a game-changer for industries relying on high-speed drilling operations in challenging materials like stainless steel and hardened steels.

Rocky Mountain Blue™ nACo® Coating represents a significant leap forward in cutting tool technology. With its nanocomposite structure, extreme thermal stability, low friction coefficient, and proven tool life extension, it sets a new benchmark for performance-driven machining applications.

By incorporating this next-generation coating, manufacturers can achieve increased productivity, lower tooling costs, and enhanced machining efficiency, making Rocky Mountain Blue™ a must-have solution for high-performance drilling and machining.

Toolholder selection plays a critical role in achieving high accuracy, repeatability, and performance. Among the various options available, hydraulic milling chucks provide a versatile and efficient niche solution. But how do they compare to ER collet chucks, end mill holders, and shrink-fit toolholders? In this article, we'll delve into where hydraulic chucks fit as the best choice in some applications.
​
Why Choose Hydraulic Chucks?
Hydraulic toolholders are best suited for applications where precision, vibration damping, and high gripping force are essential. Their hydraulic expansion mechanism provides uniform clamping pressure around the tool shank, reducing runout and improving surface finish.

These benefits make them particularly well-suited for:

• High-speed milling – Superior Total Indicated Runout (TIR) control enhances tool balance, reducing vibrations and extending tool life.
• Finishing applications – Improved accuracy and rigidity result in superior surface quality.
• High-precision holemaking – Consistent tool positioning ensures tight tolerances in drilling, reaming, and boring operations.
• Five-axis machining – Low runout and uniform clamping pressure help maintain precise tool engagement in complex multi-axis toolpaths.

​
Hydraulic Milling Chucks tend to excel across various industries and machining tasks. They’re particularly well-suited for applications in:

• Aerospace & Defense - Achieve precision in critical components where tolerances are non-negotiable.
• Medical Devices - Produce intricate parts with confidence in accuracy and surface quality.
• Mold and Die Manufacturing - Ensure flawless finishes on molds and dies for high-production environments.

​Hydraulic Chucks vs. ER Collet Chucks
ER collet chucks are widely used in general machining applications due to their flexibility in gripping a range of tool diameters. However, they have inherent drawbacks when compared to hydraulic chucks:

• TIR Control – Ultra-precision ER collets are available with TIR specifications of less than 0.0002" (5µm) with the right collet and careful operator set-up and installation in a presenter with a torque wrench, whereas hydraulic chucks can easily achieve runout as low as 0.00012" (3µm) at 3×D, with just a t handle wrench ensuring precise tool positioning and superior surface finishes.
• Clamping Force – Hydraulic chucks distribute uniform pressure around the tool shank, preventing slippage and reducing micro-movements, unlike ER collets, which apply force from the sides and may introduce slight misalignment due to over torque (collet twisting) or under torque (tool slippage).
• Setup Efficiency – Hydraulic chucks enable fast, tool-free setup, whereas ER collets require torque wrenches and careful tightening to maintain consistent holding power.

Hydraulic Chucks vs. End Mill Holders
​End mill holders provide the most secure mechanical grip using a set screw to hold the tool in place, making them an economical and widely used choice for milling applications. However, it goes without saying that they fall short in most other areas:

• TIR and Concentricity – Set screw holders often introduce runout exceeding 0.0005” (12µm), which can reduce tool life and compromise precision.
• Vibration Dampening – Hydraulic chucks significantly reduce cutting forces and chatter, leading to smoother operation and longer tool life.
• Surface Finish – Reduced vibrations translate to improved finish quality compared to end mill holders, which can introduce chatter due to uneven clamping pressure.

As a general rule you should NEVER use an end mill holder for tools smaller than 5/8" diameter shank. 

Hydraulic Chucks vs. Shrink-Fit Toolholders
​Shrink-fit toolholders offer high rigidity and precision, making them a top choice for high-speed machining. Unlike shrink fit tool holding systems that require extensive setup or heating equipment, Hydraulic Chucks offer a straightforward setup process. Shrink fit also come with drawbacks in cost and handling:

• Investment Cost – Shrink-fit systems require specialized heating and cooling equipment, increasing initial setup expenses, whereas hydraulic chucks offer similar precision and rigidity without the need for additional equipment.
• Ease of Use – While shrink-fit holders require heating cycles to install and remove tools, hydraulic chucks allow for rapid tool changes with a simple tightening screw.
• Heat Sensitivity – Shrink-fit holders can be susceptible to dimensional changes over time from thermal expansion and contraction, whereas hydraulic chucks maintain consistent clamping pressure at all times.

When compared to other toolholding methods, hydraulic chucks stand out for their ease of use, precision, and efficiency. Their locking mechanism simplifies tool changes, reducing downtime and eliminating the need for costly setup equipment like shrink-fit machines or precision presetters.
​
Unlike ER collet chucks, which require careful torque adjustments, or end mill holders, which can introduce excessive runout, hydraulic chucks provide consistent clamping pressure with minimal operator intervention. This streamlined setup not only enhances machining accuracy and tool life but also increases shop productivity, allowing machinists to focus on throughput without sacrificing quality.

For shops looking to improve accuracy, tool life, and machining efficiency, Techniks Triton Hydraulic Milling Chucks are an excellent alternative to ER collet chucks, end mill holders, and shrink-fit toolholders. Their combination of precision, rigidity, and cost-effectiveness makes them the preferred choice for manufacturers seeking to optimize machine performance without unnecessary complexity or expense.
