Are these actually 6.5 mm? a 1/4 inch rod needs to slide through the hole.** A: Diameter is actually 6.5mm, 1/4 for reference. Blade length 63mm, whole rod 110mm **Q: Will these bit fit my porter cable 450 router???** A: Although routers typically have 1/4” collettes (also 1/2”) this is not the proper bit for the side cutting action needed for router applications. Will it fit? Yes. But I don’t believe it will do what you want without breaking. **Q: Are they cobalt coated or cobalt alloy?** A: Hello there, They're 5% cobalt alloy. Not coated ## Customer Reviews ### ⭐⭐⭐⭐⭐ Horse trailer floorboard install *by N***S on March 10, 2021* Bought these based on the recommendation of a reviewer for the bolts I used to install the floorboards. Broke two total which was A LOT less than I expected to. These were a huge time and money saver as I didn't have to go to the big box store and spend a lot more on individual bits.If you are buying these for a floorboard or similar project, well worth it!! Great set of bits! ### ⭐⭐⭐⭐⭐ Used to drill out grade 8 bolts in a bulldozer track *by T***C on December 7, 2019* They are sharp and true. They do have cobalt in the metal which makes them prone to the cutting edge breaking when bound against the last part of the cut. If you are using is a hand drill expect this. I was able to drill though track bolts (grade 8) on the master link. If I kept a close watch on the amount of pressure i was putting on the bit I had no problem with the cutting edge breaking. I never broke a bit except the cutting edge which was my fault,Overall great bit especially for the price. ### ⭐⭐⭐⭐⭐ This is the go to Drill Bit!
