Unittool Hole Punching over Drilling

Unittool Hole Punching Over Drilling

In metal fabrication, creating precise holes is a critical task. While there are various methods available, Unittool tooling stands out for its efficiency and versatility, especially compared to traditional drilling.


Material Versatility

Unittool tooling is exceptional in its ability to handle a diverse array of materials. It efficiently punches through:

  • Mild Steel (up to 3/4″ thickness)
  • Aluminum
  • Stainless Steel (up to 1/4″ thickness)
  • Copper
  • Brass
  • A36
  • Composite, laminated materials, fiberglass, plastic, rubber

This wide range of compatibility outshines traditional drills, which may struggle with certain thicknesses or material types.



Unittool tooling guarantees precision and consistency in hole quality. With its custom-made tooling, it ensures uniform holes across various materials, an aspect where drilling can sometimes falter, especially on a large scale or with difficult materials.



Speed is a significant advantage of Unittool tooling. It can punch holes in a fraction of the time it takes to drill them, especially beneficial in projects with a high volume of holes. This efficiency can greatly accelerate project timelines.

Create Hole Patterns with Unittool Tooling

Create Hole Patterns with Unittool Tooling

Are you looking to streamline your hole punching and part notching processes? Look no further than Unittool. Our innovative tooling system offers a range of units that can be used together to create precise hole patterns and edge notches, making the production of parts faster and more efficient.

Create a Hole Pattern in Parts

The Unittool system is designed to simplify the creation of hole patterns. With its c-frame casting and precisely aligned punch and die, you can achieve accurate results. The key to creating the desired hole pattern is the round pilot pin located at the bottom of the unit. By inserting it into the designated hole in the mounting system, such as a mounting template, you can easily achieve the desired outcome.

But what if you require a shaped hole? Unittool has got you covered. An additional diamond pilot pin, also known as an orientation pin, maintains the orientation of the shape within the hole pattern. This ensures consistency across multiple batches of parts. The Unittool system empowers you to create complex hole patterns without sacrificing accuracy or efficiency.

Embrace Unittool for Enhanced Efficiency

The Unittool system offers a host of advantages that can significantly enhance your manufacturing processes. Its ability to create precise hole patterns, combined with its rapid setup time and increased production speed, make it a game-changer for businesses aiming to improve efficiency and productivity.


Whether you are looking to streamline your existing operations or stay ahead of the competition, Unittool can help you achieve your goals. Say goodbye to tedious setups and hello to a more efficient and productive future.

Tooling Maintenance

Expert Maintenance Tips for Long-Lasting Unittool Performance

To optimize the performance of the Unittool Tooling System, we recommend the following tool maintenance procedures:

  • Sharpen punches and dies frequently.
  • Lubricate internal components during normal tool maintenance and at intervals during punching operations.
  • Replace worn components such as springs and retainers as required.

Lubrication & Assembly:

1: Disassemble unit. Clean and inspect internal components.

2: Externally lubricate outside diameter of guide body. Type GN metal assembly paste or die grease is recommended.

3: Reassembly of Unittool unit. Place conical lifter spring over outside of guide body.

4: Reassemble guide body with lifter spring into holder guide bore.

5: Align guide flat with retainer flat in holder.

6: Secure retainer and guide with fastener.

7: Insert punch body into stripping spring.

8: Externally lubricate punch body with Molykote GN metal assembly paste.

9: Align punch flat with retainer pin hole in guide. Insert punch retainer pin.

10: Tighten die fastener with hex key wrench.

11: Check pilot pin die adapter fastener, securing it to holder.

12: Wipe all debris from bottom of unit machine surface before mounting.



Frequent sharpening will extend your tool life, lower the press tonnage you need and produce higher quality holes.  Tools not sharpened at the proper time demand additional pressure on the cutting edges which will deteriorate more and more rapidly. This in turn will decrease the hole quality and the quantity of holes that can be produced by that punch or die. Therefore, frequent sharpening is by far the least expensive way to produce consistent high quality holes. Unittool recommends a surface grinder and vee block for quick tooling maintenance. Dies that have been sharpened in the field may need to be shimmed to sustain uniform die height.
Regular maintenance is crucial for optimizing the performance of the Unittool Tooling System. This includes frequent sharpening of punches and dies and lubricating internal components, ensuring longevity and high-quality hole production!

101 Ways to Use Unittool

7 Reasons to Use Unittool

What Unittool offers is speed other technologies can’t match. Here are seven ways we outpace the other guys when it comes to punching holes in extruded or shaped parts.








Faster Production Speed

With a Unittool system, you get more holes in parts per hour. If you’re finishing 400 parts in a day now, imagine 2,400 instead.

Faster into Production

We can provide most Unittool tooling within days, so there’s no need for you to wait weeks or even months as you would with other technologies.

Faster Setup Time

When you need to change from part to part, Unittool tooling accommodates. Simply swap out one of our dedicated setups for another with little wait time.

Ease of Use

Unittool tooling is designed to be easy for you, the user. It takes little time to train team members on our systems.

Fewer Bottlenecks

When manufacturers have a backlog of work for a piece of equipment—drill, laser, CNC machine or other tool—they have a problem. Processes occurring later in production stall, costing money and threatening deadlines. Customers who use Unittool systems eliminate many of these delays.

Simple Maintenance

Maintenance is simple and fast with the Unittool system. There’s no need to completely disassemble the tool or remove it from the shop floor as there is with other technologies like die sets. On a Unittool system, you can easily replace punches and dies in the press.

Easily Accommodate Design Changes

Parts and designs change over time. That’s why it’s important for manufacturers to have systems that can adapt to change. Our tooling can quickly adjust to meet new specifications, which means shorter wait times.

101 Ways to Use Unittool


Are you ready to unleash the true potential of hole punching? Look no further than Unittool, the ultimate tooling solution that has revolutionized the way industries across the board approach hole punching in extruded or shaped parts. With Unittool, the possibilities are truly endless. Here, we present to you 101 remarkable ways our technology has transformed various industries and empowered our clients to achieve unparalleled success.


Unlocking Endless Possibilities in Hole Punching

How It Works

How The Tooling Works

The Unittool system is a catalogue of units that can be used alongside one another to punch holes and notch edges to make a part. The most widely used design is a c-frame casting that has been machined to precisely hold the punch and die in alignment with the centerline of the round pilot pin.


Each unit is complete with its own stripping spring that pulls the punch back out of the part after the hole has been made. In most units, a metal sleeve called the guide holds the part down as the stripping spring pulls the punch out of the part.


What You Need

Unittol tooling is designed to work in press brakes and punch presses. Mount several units in your press to punch all the holes in one hit.


How to Create a Hole Pattern with Unittool Tooling

The round pilot pin on the bottom of the unit is used to achieve the desired hole pattern by inserting it into the designated hole in the mounting system (such as a mounting template).


When a shaped hole is required, an additional diamond pilot pin (orientation pin) is required to maintain the orientation of the shape in the hole pattern. The mounting system maintains the hole to hole pattern from one batch of parts to the next.
