What is the Husqvarna Redi Lock System?
The Husqvarna Redi Lock system is an innovative and highly secure attachment system for diamond grinding segments. Its design is centered around a simple yet incredibly effective principle: a dovetail groove on the tool and a corresponding slot on the tool holder. A small metal wedge is tapped into place, locking the diamond tool with immense force.
This system eliminates any chance of the tool rattling or coming loose, even under the most demanding conditions. When you’re tackling aggressive grinding on hard concrete or removing thick epoxy coatings, the Redi Lock system provides the confidence that your diamond tools will remain firmly attached to the grinding head. The all-metal construction ensures longevity and resilience, making it a favorite among contractors who prioritize durability and safety on tough jobs.
What is the HTC EZ Change System?
As its name implies, the HTC EZ Change system is all about speed and simplicity. Developed by HTC, a pioneer in the floor grinding industry, this system allows operators to swap out diamond grinding segments in seconds. The tools feature a tapered back that fits snugly into a corresponding slot on the grinding plate.
A few firm taps with a plastic or rubber mallet are all it takes to seat the tool securely. To remove it, you simply tap it out from the side. This rapid changeover capability is a massive advantage during multi-step processes like concrete polishing, where you frequently switch between different grits. While very secure for most applications, its friction-based design is less mechanically robust than the Redi Lock’s wedge, making it slightly more susceptible to dislodging on extremely uneven or rough surfaces.
Head-to-Head Comparison: Redi Lock vs. EZ Change
While both systems are excellent, their design philosophies lead to different strengths and weaknesses. Understanding these is crucial when comparing HTC EZ Change vs Redi Lock compatibility and performance for your specific needs.
Locking Mechanism & Security
The most significant difference lies here. Redi Lock’s metal wedge provides a positive, mechanical lock. It’s virtually impossible for a tool to come off accidentally. This makes it the superior choice for high-torque applications, aggressive grinding, and situations where operator safety is paramount. EZ Change’s tapered friction fit is highly effective and secure for 95% of jobs, but there’s a small theoretical risk of a tool coming loose if it hits a significant obstruction at high speed.
Speed of Changeover
HTC EZ Change is the undisputed winner in this category. An operator can change a full set of tools in a fraction of the time it takes with Redi Lock. For jobs requiring frequent grit changes, such as polishing from a 30-grit metal bond up to a 200-grit, the time saved with EZ Change can add up significantly over the course of a day, directly impacting your labor costs and profitability.
Durability & Longevity
Both systems are built to last, but Redi Lock has a slight edge due to its all-metal construction. The metal wedges are extremely durable and can withstand years of hammering. The EZ Change system’s plastic or rubber locking strips are considered a wear item and may need periodic replacement to maintain a tight fit, representing a minor long-term maintenance cost.
Tool Availability
Historically, each system was tied to its respective brand. However, the market has matured, and today, many third-party manufacturers produce high-quality metal tools and diamond segments for both Redi Lock and EZ Change platforms. This means you have a wide selection of tooling options regardless of the system you choose.
The Husqvarna & HTC Merger: What It Means for Tool Compatibility
Here’s where the story gets interesting and answers a critical question for many contractors: Who owns HTC floor systems? In 2017, Husqvarna Group acquired HTC Sweden AB. This strategic move brought two of the biggest innovators in the surface preparation industry under one roof. For a time, the two brands operated with their distinct tooling systems, creating a compatibility challenge for contractors who owned machines from both brands.
Recognizing this issue, the unified Husqvarna,HTC entity developed a brilliant solution. Newer Husqvarna PG and HTC Duratiq grinders are often equipped with a “Multi” tool holder. This new generation of tool holder is ingeniously designed to accept both Redi Lock and EZ Change tools natively, without the need for any adapters. This merger-driven innovation represents the ultimate solution to the tooling debate, offering contractors unparalleled flexibility.
How to Use Both Systems on Your Grinder: Adapters & Multi-Tool Holders
If you don’t have a newer machine with a multi-tool holder, don’t worry. You can still achieve universal compatibility. This is where adapter plates and multi-tool holders come into play, solving the common dilemma: can you use HTC tools on a Husqvarna grinder?
Adapter Plates
Adapter plates are the simplest solution. These are metal plates that bolt onto your grinder’s existing head. For example, if you have a Husqvarna grinder with Redi Lock holders, you can buy a `husqvarna redi lock adapter for htc ez change` plate. This plate will have the EZ Change slots, allowing you to run HTC tooling. The same is true in reverse. The main drawback is the added height and weight, which can slightly alter the grinder’s balance and performance.
What is a Multi Tool Holder for a Floor Grinder?
A multi tool holder is a direct replacement for the original tool holder on your grinder head. Instead of a plate that sits on top, you unbolt your old single-system holder and bolt on the new multi-system one. The husqvarna multi tool holder for grinders is the official solution born from the merger. It’s a single piece of hardware designed with slots for both Redi Lock and EZ Change tools. This is the most elegant and effective solution, as it maintains the original grinder height and balance while providing maximum tooling flexibility.
So, to the question, Do I need an adapter for Husqvarna Redi Lock tools? The answer is: only if you want to use them on a non-Redi Lock machine that doesn’t have a multi-tool holder. The system is native to Husqvarna grinders.
Choosing the Right System for Your Job
The best system often depends on the task at hand. Your approach to how to select diamond grit and tooling should be informed by the job’s specific demands.
- Aggressive Grinding & Coating Removal: For removing thick epoxies, glues, or leveling very uneven floors, Redi-Schloss is the winner. Its unshakeable locking mechanism provides the security and peace of mind needed when the concrete grinder is under maximum load.
- Hard Concrete Grinding: On extremely hard concrete, you need maximum pressure and a secure tool bond to ensure an effective cut. Again, the robust nature of Redi Lock makes it a preferred choice for this demanding application.
- Concrete Polishing: For concrete polishing projects, EZ Change shines. The process involves 6-8 (or more) sequential grit changes. The time saved by quickly tapping tools in and out can dramatically increase your productivity and reduce operator fatigue.
- General Surface Preparation: For general prep work on moderately smooth floors, both systems perform exceptionally well. Here, the choice may come down to operator preference or the tooling you already have in your inventory.
Final Verdict: Which Tooling System is Best for You?
So, after comparing Husqvarna Redi Lock vs HTC EZchange, which system should you invest in? The best choice depends entirely on your business priorities and the type of work you do most often.
Choose Husqvarna Redi Lock if:
- Your primary work involves aggressive grinding, heavy coating removal, or working on very uneven surfaces.
- You prioritize maximum tool security and durability above all else.
- You don’t mind a slightly slower tool changeover process in exchange for a rock-solid connection.
Choose HTC EZ Change if:
- Your business focuses heavily on multi-step concrete polishing where speed is critical.
- You value efficiency and minimizing downtime during tool changes.
- Most of your work is on relatively flat surfaces for light to medium prep.
Ultimately, thanks to the innovation spurred by the Husqvarna,HTC merger, you no longer have to be locked into one system. By investing in a machine with a Multi tool holder or upgrading your current grinder with one, you get the best of both worlds. This allows you to build a versatile arsenal of diamond tools and choose the perfect segment for every single job, maximizing your performance, profitability, and the quality of your finished floor.
