  1. Great information! Best explanation of the three types of drills I've heard yet. I think I need the impact driver for the picket fence I'm building. My old Black and Decker drill died on me while using a 3 inch screw. I can't seem to find any with cords, however. I wonder if I'll have to stick with a regular drill if I want a cord?

  2. I'm a Licensed Journeyman Electrician with over 52 years in the trade . I specialize in Residential & Commercial Electrical Wiring and Maintenance. I own and use Dewalt 20V Max Lithium-Ion 1/2'' Hammer Drill, a Dewalt 20V Max Lithium-Ion 1/2'' Drill/Driver and a Dewalt 20V Max Lithium-Ion 1/2'' Impact Driver. I can drill 3/4'' holes in 2×4 Stud Framing all day long and only have to change the battery out once when using the 4-hour 20V battery. I always use the Hammer Drill when doing Electrical Rough-In wiring because if I should by chance hit a hard knot hole in the stud, the Hammer Drill goes through it like a hot knife through butter ! I also have a complete set of Masonary Bits of different lengths and sizes that I use with the Hammer Drill when drilling through Brick or concrete cinder blocks. I use the Impact Driver when mounting electrical boxes and panels in both wood constructed buildings and or steel purlins in Steel Framed Metal buildings . I have used all kinds of Power Tools, corded and cordless by several other manufacturers over the years and have found that Dewalt Power Tools are the BEST on the Market. I also own a Milwaukee 1/2'' Right-Angle corded Drill and a Milwaukee Sawzall and a 1/2'' Sears Craftsman 1/2'' Big Drill, corded. But I prefer and use the Dewalt Power Tools the most and Dewalt is the only brand that I buy now. Where is Your Dewalt 20V Lithium-Ion Hammer Drill when drilling into that concrete cinder block ?

  3. I have a nice cordless drill and an impact driver but I need to drill holes in steel. Is the hammer drill right for that job?

  4. Ugh… way too simple and avoids the real issues. First off, most laborers like to use the impact driver because it takes less effort. OK, so what is the problem with that? Answer: We are building something (using fasteners) to get a quality structure, and this takes more knowledge than just slamming fasteners in with an impact driver. Take a situation where we want to fasten something like sistering a 2×10 to another 2×10 already framed in, and you want a tight fit with the materials pulled together by the fasteners. The impact driver won't draw in the materials properly if you just slam the fasteners in. You will get a much tighter fit, if you use the drill driver to go in with the screw, reverse the drill and pull out a bit when the materials separate, and then drive the screw home. This is especially true when you drive a fastener into older lumber that has dried out. In many cases, you need one drill gun to pilot drill the hole, and a second screw gun to drive the screw, and reversing, to get a tight fit. And often it helps to put some oil on the screw to get a tight strong joint.

    What happens when you get Joe "Just Use a Bigger Hammer" mindset using an impact driver? Either the bit breaks, the screw heats and snaps, or the material splits. Something is likely to give, when you hammer on it with the impact driver. Sometimes everything looks good on the surface, but if you take some screws out you find that they were either stripped or snapped, or the piece falls apart because the wood was split. Since we want a structure to stand up, and not fall down, snapped or heat damaged screws and broken structural lumber compromise the quality of the job. Have Joe Big Hammer follow up and infill fasten the pieces, but use the drill gun/screw gun to initially fasten materials that need a tight strong joint. It also helps to set the mentality, by getting your crew to initially drive the screw at the slower speed on the adjustable screw gun by lightly depressing the trigger instead of driving it in at full speed. Then after reversing, drive the screw home using a stronger trigger pull and getting a higher speed. Practice these techniques, and build much better structures.

  5. Once I found hammer drills I never touched my standard drills again.
    Then again even when I used drills I always had it on the highest clutch setting and let my finger dictate when to stop.
    If you need a clutch to not strip screws you ought not be building things.

  6. ToolMetrix.. thank u. i liekd this video because some guys really talkk way to much an dont get to the point till they have wasted 10 minutes of our time..

  7. Short, simple and very informative. Came to learn about drill vs impact driver and also learned about the hammer drill as bonus.

  8. As and electrician, I like the hammer drill best for my tool belt carry. It can do everything well enough. While impacts can do certain tasks better, there are other tasks they can't do at all. The versatility makes it choice for me. The only time it feels like it falls behind is when driving long wood screws. Most the time I can manage without stripping them by dropping to a lower motor speed and applying pressure with short trigger presses. But if I have to drive a lot of long screws into wood, or if I have to drill into wood that may have nails or at a position that I can't stabilize the drill well, I'll run out to the van and grab my impact.

    95% of the time, I'm using my hammer drill.

  9. Hi, I got me a ryobi drill (18v) and a craftsman impact (19.2v) from sales events. Are these two any good or was I in the wrong picking? Thanks.

  10. Well explained Sir direct to the point not like the other long videos that's confusing. Thank you very much!!! Now I know I need a hammer drill for concrete haha!

  11. Thanks for the information. Could I ask a question. I want to buy a drill or is it an impact driver that I need for building stuff in the house like chairs, tables, tv stand e.t.c . So I need something affordable because I have to ship it to Kenya again. Which drill should I buy?one that also has adequate drill bits even the ones for making bigger holes. Thanks in advance.

  12. GREAT VIDEO!!! You explained it perfectly. I wasn't sure the difference between the impact and hammer drill workings. I need to drill into cinder block walls. So now I know to look for a hammer drill. Thank you!!!!

  13. …or drilling through wet, pressure treated 4x6s with a 1/4 in bit. Found out the hard way a regular drill wasn't going to cut this and a hammer drill was needed.

  14. Great explanation and demonstration! Have been trying to use an impact drill when I should have been using a hammer drill – now I know! Thanks!

  15. I would have liked to have seen all three on wood, steel, and concrete using same bit. That would give an idea of how much better or worse each one is. A Bosch all material drill bit would work for this.

  16. Percussion drill not hammer drill. I know they call it a hammer drill but a hammer drill has an sds type of chuck and revs slower harder hammer drill ! Percussion drill as a hammer drill wont last long on big jobs . Just saying

  17. Can you use a hammer drill with a hole saw? Also, what should the torque be for drilling rather thin plastic box/tote lids? Thank you.

  18. Not only was this video perfect for explaining the difference between the 3 different tools, it could (and should) be used as a how to make concise and informative videos on YouTube. All facts and useful info with zero time wasted on rambling and close-ups when appropriate. Excellent video!

  19. Thank you. I’ve never had to use any power tools in my life until recently and I was completely clueless. This was a question I had and you nailed it in under 5 minutes.

  20. Super helpful video. Do you think the hammerdrill then would be best option for drilling a couple of small nail / screw holes in apartment cement walls? (hanging pictures first – will focus on heavier things once I can do the basics)

    Thanks to videos like yours I was able to hang shelves all over the place on the drywall – now I must expand to the cement walls.

  21. Great explanation!!! It helped educate a novice like myself!!! Thank you for sharing your knowledge!!! ☮️🖖🏽

  22. I'm a cable guy and can't live without my 12V impact driver. Use it all day long to drive screws, and the 12V is more than powerful enough while being compact and lighter

  23. If you are drilling into concrete a lot spare yourself the trouble and just get a rotary hammer drill. A rotary hammer makes a regular hammer drill seem like a kids toy.

  24. I was trying to drill through brick with my cordless, underpowered drill. The term 'getting nowhere in a hurry' is the perfect description. Using youtube to find info on what to do was almost as fruitless, until I found this video. Thanks so much for the most informative comparison of drill types. I'm ordering a well rated hammer drill now. Oh, and I'm now subscribed.

  25. What I would need is an Impact Drill with a VARIABLE SPEED. 1 tool that could do ALL of those things except it's corded. I've used it many times and it didn't fail on me. One thing to note though is how to properly adjust the speed of your drill.

  26. Thanks a lot for this great video, I was unsure of the differences between the types of drill and you've helped me realise that for the woodwork projects I'm planning I really will only need a very basic drill. I'm a total beginner with this so I appreciate the clear and helpful video a lot 🙂

  27. Clear explanation, very helpful! I'm just somewhere between a drill driver and a hammer drill. Now I've got a clear picture about that. Thank you so much 🙂

  28. Thank you so much! I have to take on carpentry at the home and needed to know why my black and decker drill wasnt going through the brick. You have explained it clearly and I am looking to rent a hammer drill for this work I'm about to do! 😊

  29. Excuse me if this was said earlier, but where the impact driver REALLY comes into play is removing screws without stripping their heads.

  30. Is it possible to get screws with torx head and not Philip's in US. Here in Denmark almost all screws are torx. It's a bad day if you rip a torx head. And if you do, your bit is probably bad.
