Rip Rap stone is rough stuff but softer than river rock. That is the only way I can explain what it is like. Little bit more info to add you might want to add.
Just like the larger the hole. The harder the material, the slower the speed. This may not always be the case but generally speaking this it true. Thank you so much for sharing this post with us!! These are detailed tips! This is so timely as I am looking for a drill as I will be mounting a safe in our wall. Thank you for sharing!
Does one offer guest writers to write content in your case? Again, awesome website! Thanks for the post, I am a mother and this helped me! I really dont know the difference between any of these drill bits, and still not sure. Thanks for this great post, I find it very interesting and very well thought out and put together. I appreciate you mentioning the importance of using the correct speed settings to ensure you get the desired finish when drilling.
My wife is getting into more DIY projects like a chair made from pallets and different shelving systems around the house. I imagine some jobs like deep hole drilling that require precision and special equipment are better left to the professionals. The deeper the hole the less precise it will be, unless using very expensive equipment to aid the process.
Cordless hammers are very suitable to use. Thank you for the post. Wow, what an informative article you published here. Real information helps to avoid common mistakes when we use a drill.
Hopefully the articles will help a beginner. Thanks for sharing. Great tips, thank you. My problem is Tiles — no idea what I am doing wrong! I have a tile bit, wet tiles, slow speed, stop often, taped up..
It is uncanny. Researching what I could be doing wrong brought me to your page. I think I mostly do all the things right. Tile drilling is a difficult issue. The best kind of drill is definitely a dedicated diamond bits BOA which come in various sizes. Very helpful information. I have a question. Specially designed for drilling into masonry or rock using a rapid hammer action, these drills and their carbide-tipped masonry bits are widely available at tool rental shops.
When renting or buying a hammer drill, look for one with good power, ideally more than one speed setting, a stop function, and an auxiliary handle for your spare hand for enhanced comfort, control, and safety. Mark the desired position of the holes in pencil on the concrete surface, and double-check their locations before you proceed. Also, during this planning and prep work, consider the drilling depth necessary for each hole.
No stop bar feature? Instead, wrap a piece of masking tape around the drill bit to show you where to stop. Don your goggles, then insert the appropriate tungsten carbide masonry drill bit for your desired hole size into the hammer drill. Next, get into position to drill by planting your feet firmly on the ground, shoulder-width apart.
When you lean in to bore the hole, the drill bit should be perfectly perpendicular to the concrete. The Real Tom Contact options for registered users. Reply to The Real Tom. SteveB Contact options for registered users. Reply to SteveB. One of the more stupid questions ever posted on here.
ALL drill bits get dull if they are used, as well as all saw blades and anything else thats used to cut material. Scissors get dull cutting paper, chisels get dull, knives get dull cutting food.
It's just common sense. Reply to maradcliff. Rudy Contact options for registered users. Should do hundreds if not thousands of holes. A v rotary hammer drill with sds chuck. Letting the drill do the work and having a drill powerful enough to run at optimal speed will help the longevity of the bits.
Thanks Sandp. Anyway, I'm going to bunnings tomorrow and have chat with them too! The problem your having is one many people have run into, myself included, and its not the drill bits. Its the drill you're using. For drilling masonary, the drill hits the drilling surface like somebody using a hammer and chisel, enough to crack the top layer but not enough to wedge inside the surface and cause it to fracture. Then it turns a little bit, causing the pulverised material to run up the drill and away from the drilling surface.
Repeat, dozens of times a second, each time removing a tiny amount. This is how the drills are meant to be operated. What you have is an undersized drill, that can't pulverise material fast enough, so each hole ends up taking 10 minutes to drill. It spends more time rotating than delivering the hammer motion, wasting energy in the form of friction.
