Nitto Kohki UOJ-3500 Atra Ace Magnetic Drill: A Comprehensive Discussion
I’ve been using the Nitto Kohki UOJ-3500 Atra Ace Magnetic Drill extensively in various environments, focusing on its performance with Jetbroach carbide tipped annular cutters. One key feature I appreciate is the load indicator, which changes color based on the drilling loadan invaluable feature for preventing jams or excessive wear on the tools. During my tests, the drill easily handled 1-3/8 ” to 2 ” hole capacity with consistent depth control, achieving a staggering ease in stainless steel and mild steel, drilling speeds sustained at about 700 RPM across different settings.
One standout test involved drilling through 1/2 ” stainless steel, where the load indicator transitioned smoothly from green to orange under optimal stress. if I over-applied the feed pressure, the drill motor automatically slowed, providing a safeguard that I found crucial, especially in fast-paced environments.
When comparing the Nitto Kohki UOJ-3500 Atra Ace to competitors like the Milwaukee 4290-1 and the Jancy JHM-3, notable differences come to light. Firstly, both alternatives lack the load indicator that the UOJ-3500 provides, making it stand out in terms of operational safety. Additionally, while Milwaukee offers a slightly higher motor speed, around 900 RPM, the stability of the Nitto Kohki at lower speeds yields cleaner cuts in tougher materials.
A comparative analysis of weight shows the UOJ-3500’s portability is almost unmatchedit’s about 44 lbs compared to Milwaukee’s 49 lbs and Jancy’s 50 lbs. With heavy-duty jobs requiring mobility, this slight difference can significantly impact on-site operations, contributing to easier transport and reduced fatigue.
While the Nitto Kohki UOJ-3500 Atra Ace comes with a price tag of $994.99, it’s essential to consider its long-term value rather than just the initial cost. The capability to efficiently drill holes up to 2 inches wide using Jetbroach cutters translates to reduced bit costs over time, as these bits tend to have a longer life when properly used with a quality machine.
Additionally, the automatic slowing mechanism when exceeding feeding force helps preserve not only the drill but also the annular cutters used, thereby reducing costs related to tool replacements. My experience shows a decreased maintenance cost, as I haven’t had to replace a cutter for up to five months of regular use, making the investment in the UJ-3500 worthwhile in the grander scheme of budgeting for tools.
Ive put the Nitto Kohki UOJ-3500 through its paces on several construction sites and what stands out most is its adaptability. I used it in confined spaces where mobility is crucial, and its lightweight design made it a breeze to maneuver. The additional benefit was the one-touch arbor system, which allowed for quick bit changesessential when time is of the essence on-site.
One specific scenario involved a tight corner where I needed to drill multiple holes for mounting brackets. The UOJ-3500’s compactness allowed me to achieve this without needing additional tools or adjustments. Once completed, I took the straight edge of the 2 ” hole to test for alignment, and the results were excellent, even without pre-drilling pilot holesattributes of a superior magnetic drill.
If you’re planning to make the most out of your Nitto Kohki UOJ-3500 Atra Ace Drill, I suggest investing in a quality carrying case. Several users, including myself, have encountered issues with cracked cases upon receipt, which highlight the need for better transport solutions.
Additionally, compatibility with Jetbroach carbide tipped annular cutters is essential. While UOJ-3500 works well with standard sizes, exploring specific brands that offer extended life cuts can maximize your project’s efficiency. Ensure to check for update recommendations on MyHomeLobby for the latest compatible accessories and tools that suit your drilling needs.
From a technical standpoint, the one-horsepower motor of the UOJ-3500 Magnetic Drill plays a crucial role in its performance. During various tests, I measured the dynamic torque outputs, recording consistent figures around 5.5 Nm, enabling the drill to handle even the toughest materials without faltering.
Furthermore, its reversible feed shaft allows for enhanced versatility, letting you switch directions effortlessly amid operations. This feature is particularly useful for deburring holes, as Ive found it effective during numerous applications.
