Wolfride 1/2-Inch Shank Router Bit Collet Extension, Adapter for 1/2-inch Shank Bits

Works great for reaching down and hogging out material with a 2 inch bit, or doing fine line work deep on the bottom of your piece. It ran perfectly straight with no vibration even with that heavy bit on there. Remember to adjust your speeds according to bit size people, and check the depths of your bits when seated in the router arbor. Stop tossing them in there and just tightening them down. I see a lot of complaints on here about wobbling. It's usually due to human error or worn equipment by those that "know what they're doing" Tools and most other things have specs on how to use them properly or set them up, speeds, depths, capacity etc. Read the material and make sure you're doing things the ACTUAL right way so you don't get hurt.I 100% would buy this again but it's solid and I doubt I'll ever need another one.

This router collet extender is exceptionally well built Very durability. Its smooth operation makes changing bits effortless, ensuring a hassle-free experience during woodworking projects. The extender’s length is perfect, providing the perfect balance of reach and stability for various applications. A high-quality tool that delivers reliable performance!

This extension is very sturdy and works good. The top nut fit my Bosch 1617 router wrench perfectly. The bottom part was just a little bigger than the small wrench. After maybe 30 min with a small file, I can use both of my Bosch 1617 wrenches without problem.

I read some of the reviews about this product. Some reviewers were concerned with vibration. I will be putting this in my drill press and measuring runout with a runout gauge. Should there be a problem, I will turn it on a metal lathe to true it up. Based on what i have observed so far it runs smoothly and when it turns warm again this winter, I will do the runout test.The threads are clean and the collett adjusts smoothly. It is a great product for those who are working with large routers and planing slabs. I purchased a 3 edge planing bit to work in conjunction with this extension. The only concern I have is the bending stresses on the router bearings. I am using this on my Porter Cable 1.75 HP router. I will be cutting no more than an 1/8" deep until I find a good comfort level with this combination.I also have a Jet Shaper and have had problems using some of my pattern bits. Often with thicker slabs, the router bits are not long enough to allow the bearing to reach the full depth of the wood. This should solve that problem.You may not use this all the time in your woodworking, but having it when you need it is good. It is a good product and the price is right.

It's big and chunky. Sometimes just a bit longer than I wish for the chuck, but it works great and I very solid. I use it often and haven't had any issues with it.It is a bit larger than the chuck on my router, so I have to use a separate crescent wrench, but that isn't a big deal. Great extension

Do not buy, I purchased three of these and all of them had terrible runout. I put them in my lathe to check the runout and had over 0.008" of runout. Completely unacceptable and will make your router vibrate like crazy.

Using it with a 2in spill board bit on 3hp router for a router sled and no signs of wear or stress that it might break

just finished router sled build but wanted flexibility for more depth and easier blade changes. Based on other reviews ordered this extension. It has about 30 hours of hard running using flattening bit and it seems rock solid. There is a little more vibration than without it but its hardly noticeable. Works fine and has not moved. would recommend the extension if your looking for one. I have not yet used it for fluted bit but not worried about its performance.
