Review: Nice! - Easy to use and good for more than 1 or 2 installations. I've used it several times and still works great.
Review: I'm doing 8 doors in my house and it's a great deal for that - This definitely get the job done. As other reviewers stated, it is a bit flimsy, but not so much that it actually affects the performance or function. It will definitely guide your bit to the correct position. If you can't hold the drill straight, this will not be rigid enough to guide it for you, but that's not it's purpose. I'm doing 8 doors in my house and it's a great deal for that. If I was a contractor doing 100's per year, I'd spend more for a better one.

## Questions & Answers

**Q: Diff between irwin tools bi-metal door lock installation kit (3111002) and irwin wooden door lock installation kit, 3111001:are both doing the same???**
A: Thank you for choosing Irwin Tools. Our goal is to provide our customers with the highest quality and service. The IRWIN Tools Bi-Metal Door Lock Installation Kit (3111002) works on both metal ad wood doors. The other only works on wood doors.

**Q: How do you separate the adapter to use the 1 inch hole saw? After using the larger hole saw it is stuck on.**
A: another option is to buy another kit or arbor if you can find one, then just keep one attached to the small hole saw and one to the larger one

**Q: How can I secure the template to the door by 2 screws when my door is a metal one? My door is new and have no holes in it for lock**
A: My door was also steel, but the steel was just the door panels. It had a wooden core. The screws go into the core. The template is only needed to start the hole saws center bit. Once the center bit drills through the steel panel it will hold the hole saw in position to drill the bigger hole. If your door is all steel, you can use a small bit to make pilot holes for the screws and attach it like the instructions say.

**Q: 1" hole saw, how didyou attach it to a drill???  The supplied attachment only work on the 2 1/8" hole saw so it won't screw into 1" hole saw for me**
A: Once you separate the bit from the adapter, it can be used with a 1" hole saw.

### ⭐⭐⭐⭐ Satisfied
*by A***D on July 23, 2024*

I recently purchased a door knob installation tool, and it has proven to be an invaluable addition to my toolkit. I used it to make precise holes in solid wood doors, and the results were impressive. Ease of Use The tool was incredibly user-friendly. The instructions were clear, and I was able to set it up quickly without any prior experience. The process of aligning the tool on the door and making the cuts was straightforward, which significantly reduced the time and effort typically required for such tasks. Performance One of my initial concerns was the quality of the plastic guide. It seemed a bit flimsy at first glance, and I was worried it might not hold up during use. However, to my pleasant surprise, the plastic guide was more durable than it appeared. It maintained its integrity throughout the entire project, providing reliable guidance for the cutting process. Accuracy The tool made highly accurate cuts, which is crucial when installing door knobs. The holes were perfectly aligned, ensuring that the door knobs fit seamlessly and operated smoothly. This level of precision would have been challenging to achieve without the assistance of this tool. Build Quality While the plastic components initially raised concerns, the overall build quality of the tool was satisfactory. The metal parts were sturdy and well-made, contributing to the tool's effectiveness. The combination of metal and durable plastic materials provided a balanced design that performed well under pressure. Value for Money Considering the cost of the tool compared to the convenience and precision it offers, I find it to be an excellent value for money. It saved me a considerable amount of time and effort, making it a worthwhile investment for anyone needing to install door knobs on solid wood doors. Conclusion In summary, this door knob installation tool exceeded my expectations. Despite my initial doubts about the plastic guide, it held up remarkably well and contributed to an easy and accurate installation process. I highly recommend this tool to both DIY enthusiasts and professionals looking for a reliable and efficient solution for door knob installations.
