Imagine you're taking a cross-country road trip. Your long route takes you through mountains and forest roads, so you're getting a tune-up before leaving. While replacing your tires, the mechanic suggests new wheels. She says there's nothing wrong with your general steel wheels, but a more robust set would offer more insurance and better performance for the long road ahead.

You pass. Your original steel wheels should be fine. Later, struggling through what was supposed to be an easy drive, you hit a deep pothole and feel your driver's side wheel bend. It's a long, rough ride to the nearest mechanic. Lesson learned: without high-quality wheels, your engine and tires can't work together to push their limits'and could even get damaged. The same lesson applies to tool holders. The cutting tool is the tire. The machine tool's the engine. The tool holder is the wheel, an intermediary converting energy into movement'and if you're pushing the limits, you need a good one.
Granted, a machining center is more durable than a wheel, but it's just as vulnerable to damage from inadequate equipment. Even in a new machine, a low-quality tool holder or shoddy spindle can wreak havoc or shorten the machine's overall tooling life. Factors like corrosion, low dimensional accuracy and instability (among others) incur costs that sting far more than a high bill at the mechanic. Fortunately, you can avoid that pain by keeping a few things in mind as you choose your tool holder.
When choosing a spindle and tool holder, you want consistent results and long service life. That's where BIG-PLUS comes in. In the BIG-PLUS spindle system, the shank contacts the spindle taper and spindle face simultaneously. The margin between the two is smaller and the contact area between the flange and spindle is larger. This greatly increases rigidity, which has huge implications for everything from ATC repeatability to boring smoothness. It also reduces corrosion and eliminates Z-axial movement at high speeds, vastly extending overall tool life.
One caveat, though: You'll only get BIG-PLUS benefits from licensed BIG-PLUS spindle systems. BIG-PLUS spindle dimensions are strictly controlled by the BIG DAISHOWA Master Gage and meant to work with BIG-PLUS licensed tool holders. Unlicensed holders may fit the spindle and cost less upfront, but they aren't guaranteed to reach peak performance or even operate safely. They can easily damage spindles, void warranties and cost you far more in the long run.
The advantages of dual-contact holders have long been well known. However, before BIG-PLUS, dual-contact tool holders were a mixed bag. They might have been standard tools altered on the fly, custom-ground one-off sets, supplemented with shims or otherwise modified to hold the spindle more closely. BIG-PLUS changed that. Its spindles and tool holders are ground to precise specifications, closing the gap between spindle face and flange in unison every time. Operators can rest easy knowing that any licensed BIG-PLUS tool holder guarantees dual contact with any BIG-PLUS spindle.
Unfortunately, there's dual contact and then there's 'dual contact.' Remember, unlicensed toolmakers don't have access to any BIG-PLUS gages or official specs. Since there's no industry standard that defines the manufacturing data and tolerances of BIG-PLUS, unlicensed toolmakers are making educated guesses through reverse engineering. Inconsistencies are inevitable. There may be space between the tool taper and spindle, causing severe chatter and vibration. Or there'll be space at the flange, effectively turning it into a badly made standard tool holder. Stick with the real thing; look for tooling marked with 'BIG-PLUS Spindle System - License BIG Daishowa Seiki.'
Are you getting the most precise tooling possible for every cut? Make sure to get a tool holder that can accommodate a variety of incremental gage lengths. When you're trying to match tooling to the exact parameters of a cut, you don't want to have to get creative or take unnecessary risks. Every millimeter counts and our tool holders offer high precision, coming in increments from 1.77' micro chucks to an extra-long 12' shell mill holder, so don't get anything longer than necessary. Find the proper holder and you can avoid any guesswork to make the right cut every time.
Think back to that long drive. You wouldn't try to drive up and down mountains in a front-wheel- drive-only minivan, right? No matter how roomy it is, it's not built for narrow turns or high inclines. Similarly, if you need to cut something at 12,000 RPM, you wouldn't put that spindle in a tool holder maxed out at 8,000 RPM, regardless of how well-made the tool holder may be. Or maybe you need something for tapping operations. In that case, high rigidity may actually make it harder to weather stop/reverse and maintain synchronization. And if you're doing full five-axis work, balance should be your top priority. Your style of tool holder should be application-specific to get the highest performance. You might need chucks, such as collet, milling, hydraulic or tapping chucks. Or you might be best served by a shrink fit holder, sick lock end mill holder or shell mill adapter. We offer all of them so you can always meet your specific needs.
CNC lathes are an invaluable piece of machinery for any modern workshop, but getting the most out of them means investing in the right tool holders. An ideal tool holder can meet your needs and requirements while staying within your budget. In this blog post, we'll explore what you need to know about tool holders and how to choose right tool holders for your CNC machines.
A tool holder is a device used to secure a cutting tool in a machine's spindle. They are used to mount cutting tools such as end mills, drills, or reamers into the spindle to be used precisely and accurately while machining material.
The importance of having a quality tool holder cannot be overstated; it should meet all performance requirements and provide a secure fit while offering flexibility if needed.
Choosing tool holders for your CNC lathe can be confusing, so we'll try to break it down. First, there are several types of tool holders that you can use for your lathe.
These include static tool holders and live tool holders, each with its own advantages and disadvantages. Each type of tool block comes in different specifications and sizes.
Static tool holders are an important part of machining as they provide a secure and consistent way of holding the cutting tool. This helps to ensure that the accuracy and repeatability of the machined parts are high, regardless of whether manual or CNC machines are being used.
Static tool holders come in many forms, such as boring bar holders, facing holders, OD holders, and cut-off holders. Each type has its own features, which make it suitable for different applications.
Live tool holders fit onto the spindle of a CNC machine, allowing for rotary motion and axial movement in all three directions (x, y, and z). This makes them ideal for complex applications such as threading and hole-making, where two or more cutters must be used simultaneously.
The holder can also accommodate various cutting inserts, providing size, shape, and material type flexibility. In addition, they can be adjusted to different speeds while maintaining accuracy and repeatability over long runs.

When choosing a tool holder for a machining process, it is important to understand the two main types of fixed tool holders available: VDI and BMT.
VDI (Verein Deutscher Ingenieure) holders have standardized interfaces that enable quick changeover times and provide high accuracy and repeatability.
BMT (British Machine Tool) holders, while not as accurate or repeatable as VDI, are faster to set up and offer more flexibility when it comes to different applications.
VDI tool holders come in several styles, including shrink fit, hydraulic clamping, and Weldon clamping. All three styles use a modular system that allows for an easy exchange of tools with minimal setup time.
With VDI tool holders, you can be confident in the accuracy of your machining operations since each holder has precise tolerances that ensure compatibility between the various components.
