How To Drill In Wood And Plastic

The most secure way to hang a coat hook, wine rack, picture or other type of wall art is to attach a screw to a stud. Also, when you are drilling three in spax or deck mates in between studs it is do large and you have to drill them at an angle other then 90 degress so the integrity of your DIY project is decreased. Of those, the Craftsman C3 17560X , Milwaukee 2606-22CT , and DeWalt DCD780C2 all produced similar results in our testing, each driving 70 to 90 screws and drilling 20 to 25 holes (remember, the 18-volt Bosch DDS180 drove 154 screws and drilled 45 holes, and the Porter-Cable runner-up drove 134 screws and drilled 30 holes).

We spent two days testing 16 drills by driving screws and drilling holes on a pile of lumber in rural New Hampshire. This will drive screws into most wood, and you can also use it to drive some lag screws. Shoulder Screws: These have precision ground shanks that remain above the head of a hole and provide a simple way to make an axel for a wheel. For traditional tapered wood screws, a countersink with a tapered drill is logically the best to use.

If you want to make the screw completely invisible, make the countersunk hole slightly deeper and fill above the screw head with wood filler paste, a plug or a piece of dowel. The drill was relegated to countersinking and large boring, all screws however were driven with the new DeWalt impact driver that I purchased almost immediately after using the one loaned to me. It is now officially the one cordless tool I can’t do without.

First, see if you can drill into a stud (the frame sitting behind the plasterboard). The pilot drill may be a standard twist drill, another type of drill bit appropriate for the material, or, when the primary purpose is precisely locating a hole, may be made with a short, stiff center drill. The power of the drill can be adjusted so that the screw isn’t plugged too tight and therefore start to affect the material you are drilling in to. The dual modes make the tool much more useful than one with just a drilling mode.

Power Screws and ACME Threads: Power screws’ job is to translate rotational motion into linear motion. Most recognized in North America is the Unified Thread Standard of 82°, which matches just about all woodworking screws you might encounter in the U.S. and Canada. Wood screws can be somewhat tricky…and cause lots of problems if you don’t have your drill set up the right way. I didn’t know whether I’d need a drywall anchor simply for the fact that I’m screwing through drywall. Grain wood without a pilot hole, the wood surrounding the screw is compressed in both the longitudinal and transverse directions.

Remove the drill bit from the drill and insert an appropriate screwdriver bit, if using the drill to install the screw. Fit a cordless drill with a hole bit that is about ¼ inch larger in diameter than the pipe you are installing. These drill points are manufactured in the same method as the high speed drill bits. Flatter points — such as those with 135-degree angles — are suited for drilling into harder material. It’s easier to drive these screws because you don’t have to press down as hard to maintain good bit contact. Driving screws at an angle (toe-screwing) is a common technique for making right-angle connections.

The most efficient way to make a countersink is to take it easy, and decrease the drill speed as the stop nears the surface. If you only have a few sheets of drywall to hang, you can buy a special tip for your cordless drill that limits the depth you can drive the screw. It’s rare to find the old-style flat steel piloted countersink bits, but they are great for drilling countersinks quickly (if inefficiently). A typical impact driver will output higher levels of torque than even the top-of-the-range combi drill.

The magnet in the bit holder magnetizes the tip, allowing you to hold ferrous-metal screws in place on the end of the bit for easier driving (top photo). Pilot holes are not necessary when installing screws in very soft materials like gypsum board (drywall). I would like a plastic gauge so I can simply poke the screws through the holes to determine their size. You will also need to get a 1/4 inch anchor kit that has plastic anchors in it with matching screws.


As indicated in the drawing, the clearance hole through the first piece of wood (which is usually the thinner of the two) should be approximately equal to the diameter of the unthreaded shank or body of the screw (the part that is directly under the head). To make the necessary recess, the simplest method is to use a countersink bit, a pointed bit with a taper at the tip that can be used after the other holes are drilled to open the top of the hole so that the screw head will sit flush with the surface of the wood as shown. A hole drilled for tapping machine screws or bolt threads in metal or plastic may also be referred to as a pilot hole.

Socket Screws: While many hex cap screws may be found in vehicles, socket head screws are becoming more popular and have some space saving advantages over hex cap screws. A bradawl or gimlet can be used to mark the point to place your small drill bit. So it’s like someone’s hitting the wrench on the bit while someone else is hitting the back of the drill.

You can buy a time-saving auto-feed version (center photo) that uses special collated screws, or a dedicated drywall screw gun (left) that drives regular drywall screws. Flat and Oval Head: The most common type of head for wood, these heads end up flush or below the surface of the wood when installed. But realize that if you don’t follow other’s advice and keep the drill lined up, this will push the drill off of the screw. The format was simple – each competitor had to drill five screws into a piece of wood secured on a workbench as fast as they could.

Amazingly, Makita warrantied the drill and completely rebuilt it for me. From now on my hammer DRILL will not see a masonry bit bigger than 1/4 inch even though Makita rates my drill for 1/2 inch in concrete. Many times it is a good idea to drill the pilot hole through the piece being attached and into the the piece you are attaching to, to the depth of the penetration of the screw, smaller than the diameter of the screw. The only need i would see is to set a mark in the sheetrock so things are lined up properly before you do the final drill.

I know it doesn?t sound that bad, but let me know how your shoulder feels after 4000 drywall screws in the ceiling! This also helps when you have an issue, you just pull the drill away and the screw falls into your hand. Regular drill drivers are only suitable for drilling into softer materials such as wood, metal and plasterboard, or for screw driving tasks.

What you have to watch out for is the torque which still amazes me when you have this petite looking drill that can sink hefty lag bolts all day. This does not work with grease or oil, and you should remember to clean off the wax before you stain or paint the wood. You do NOT want to put wood screws (small ones anyway) into drywall since they’ll just rip out at a second’s notice. Once you need to start adding more torque, you’ll want to move this hand to the back side of the drill to push hard. Those two particular angles are based on the standards to which the screws are manufactured and used.

Thus, a smaller hole is necessary as this will the screw threads to grip the material and hold on to it without splitting the wood. Then, with the bit firmly seated, start the drill slowly (assuming you have a variable-speed drill) while pushing hard against the screw. At times, drills can provide too much power, causing screw heads to snap off or strip, especially with small brass or aluminum screws. The threadless shank allows the top piece of wood to be pulled flush against the under piece without getting caught on the threads.

Self-drilling screws are available in a variety of finishes with unique product features to suit a wide range of environmental conditions. The table pretty much covers all types of screws (since it mostly covers thickness and length) so what screw you choose depends what you’re fixing. Of course, for all this to work right, you first need to have the right sized hole and a wood screw to match. The bolts will keep the hinges from pulling away from the wood and splitting it when the door that is attached to them is opened fully. This indentation will help keep your drill bit from slipping when starting the pilot hole. It looks so easy on the DIY programs, but I battle to insert screws using my drill.

Mark the position of the screw and drill a pilot hole with a drill bit slightly smaller in diameter than the shank of the screw. Flat head (counter sunk): These require a pre-drilled counter sink, and are typically angled at 82 degrees (Unified thread), which, by the way, is not the angle created by most drill bits (118 degrees). To make the screw head flush, you must use a countersink bit to drill a shallow hole into the board. It also means you are much less likely to strip screw heads and you can drive very long screws with little effort and minimal wrist strain.

The 18-volt Porter-Cable is designed for more power and more torque, so it’s a more efficient tool that strains less than a 12-volt on longer screws and wider diameter holes. Joe Truini: A cordless drill provides a great way for anyone to drive screws with power and accuracy. For the specifics of our test, the Porter-Cable 12-volt drove 76 screws and drilled 12 holes. In masonry you always have the option to re-drill the hole one size bigger (drilling through the existing wall plug) and use a bigger plug, red up to brown for example. The Dewalt Impact ready and the Milwaukee Shockwave drill bits seem to be a different story.
