Review on IRWIN SPEEDBOR Flute Drill 3041004: Unrivaled Speed and Precision for Effortless Drilling by Vedavyas Fleming

This bit gets the job done! Bits with a screw on the end that helps to pull the cutting edges into the wood are very useful for HAND drills as they do a lot require less work from the user, otherwise you have to apply a lot more force to the drill to drill it, in fact, this is a modified auger, obviously, hand drilling requires a lot more force than pulling a trigger, but it allows you to slowly and precise to move and makes a really good straight cut if you're careful this bit does it really well although it could have been sharper from the factory it's a little rough but for the price don't expect a premium bit you can easily pay over $30 for a top-notch drill bit to do something it does pretty well, so sharpen it carefully and you won't be repent However, if you use this with a POWERFUL bit, it may fall off you as the screw pulls the bit into the wood or board VERY quickly. into the drill if not securely fastened. Neither of these options is good for the user or the project. And these bits cut fast! So you can actually create some dangerous situations if you misuse this type of drill. Thought it should be said as there seems to be some confusion about this in the reviews. Many people are unfamiliar with this type of bit or its proper use. If you plan to use it with a drill press make sure it has high torque, variable speed and goes REALLY slow. This is a bit that cuts fast at manual speed. Otherwise, the driller will do what it's doing on its own and you're on your way. This is used very differently than a shovel, where things need to go fast. Never use this type of drill in a drill! Drills with this type of shank will easily loosen in a drill press designed for round shank drills. Also, it can be very, very dangerous. However, I've been able to cut through 3 inches of solid pine a few times with this bit using a pawn shop hand drill, and I was amazed at how fast it cuts. I was sweating after the first couple but it wasn't too bad. And it's summer. I'm building a cheap and very fancy modern version of an English carpenter's bench, the guy has videos and free rough plans on YouTube and has bought jigs that require a 15/16 inch deep hole. The bank is surprisingly strong but requires some effort. Work to build obviously and I modified it to suit me. But a really solid wood and bolt workbench under $100 is pretty good and will do whatever I need to do to make it very well. I didn't have the right size chisel so I bought this one. Very glad I did. Many large holes have to be drilled. And they have to be straight. It worked like a charm. Really great drill. Worth the money when you need it. Mounting hardware works great too! So no complaints. Be careful. Power tools are great for saving power but they are dangerous as everyone will get out if you don't know what you are doing or if you have the wrong tool for the job. FWIW. YMMV
