The blades are high quality. But there were no instructions for set up. I spent a while watching YouTube videos and cutting up scrap to practice with and got poor results on my project anyway. But here’s what I learned. 1) don’t even try to use these without first fine tuning your table and fence. Your set up needs to be perfect. 2) don’t even try to use these without substantial and copious feather boards. An auto-feeder would be ideal for longer boards but you’ll get away without it. 3. If you’re making a box or a hollow column and you have tried for hours to position the fence and blade perfectly for a perfect 45-degree bevel but it isn’t coming out exactly right, give up. It’s actually easier to have a slightly longer toungue on two sides and a slightly shorter tongue on the other two sides as long as you account for this by ripping to the correct width before doing your edges on the router table. You still end up with a perfect box and it’s actually easier to clamp up. Great product but if it’s your first time using this tool, you’ll want to do your homework first. Review: Nice Bits - Takes a little bit of knowledge and time to set this bit up correctly but when set up right it works very well and makes a nice joint. Recommend watching some videos on how to set up a Lock miter bit was very helpful for me. ## Features - 【Professional Woodworking Tools】 45 degree lock miter router bit uses C3/K10 cemented carbide. That is the highest grade used in router bits. After good machining and honing, the hard alloy blade has a longer service life, wear resistance, and high-temperature resistance. - 【Lock Miter Router Bit】 Connect the wooden boards at a 90-degree angle to achieve a perfect connection in an interlocking manner, and you can intuitively see how to arrange the joints to fit together correctly, good balance, clean cut edges in softwood or hardwood, without burrs. - 【Safe Handling】The lock miter router bit must be fully inserted and tightened. Use a push block for safe cutting and to help prevent tear-out. - 【Tips For Use】Using the soft-start router, and using fences and fixtures, you need to align the center line of the horizontal (table) and vertical (fence) pieces with the center point of the drill bit outline. (Therefore, the fence needs to be cut off where the drill bit extends.) You can adjust the two fences until there is a perfect miter joint that meets at the corner. - 【Satisfactory Service】 As long as you use the correct wood and make the right settings, this router bit can accurately polish the perfect wooden board for you. We provide 100% satisfactory service, if you encounter any problems during use, please feel free to contact us. We will always serve you. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08YK31T5N | | Best Sellers Rank | #16,208 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #2 in Joinery Router Bits | | Brand | Newdeli | | Brand Name | Newdeli | | Customer Reviews | 4.4 out of 5 stars 1,035 Reviews | | Cut Type | Chamfer Cut | | Item Diameter | 0.25 Inches | | Item Weight | 0.06 Kilograms | | Manufacturer | Wenzhou Yuxuan Electronic Commerce Co.,LTD | | Material | Alloy Steel, Carbide | | Material Type | Alloy Steel, Carbide | | Model | 45 | | Number of Flutes | 2 | | Part Number | 45 | | Size | 1/4shank * 1/2stock | | Size Name | 1/4shank * 1/2stock | | UPC | 744790277364 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Newdeli - **Cut Type:** Chamfer Cut - **Item Weight:** 0.06 Kilograms - **Material:** Alloy Steel, Carbide - **Size:** 1/4shank * 1/2stock ## Images ![45 Degree Lock Miter Router Bit 1/4 Shank, Newdeli 1/2 Stock Joint Woodworking Router Bit, Suitable for Furniture Oblique Tenon Interface Making (90-Degree Tenon Joint Woodworking) - Image 1](https://m.media-amazon.com/images/I/61kJI2Cq7VL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ They worked well, good quality, but no instructions, no jig. *by M***A on September 6, 2023* They worked.
