This also helps when you have an issue, you just pull the drill away and the screw falls into your hand. This gives you control so you don't tip the screw over and jam the tip of your bit into the wall. Don't grip the screw or chuck, they need to spin freely, just keep your hand there to guide things. When you first start, keep your non-dominant hand on the surface and drill chuck. Soap can help lubricate screws in to wood, making it easier and reducing screw breakage. I pick a drill the size of the screw shaft. I've heard that it may actually increase strength, but I don't know for sure. Predrilling in metal / pilot holes in wood make it easier on your muscles, reduce screw breakage, reduce wood splitting, and don't reduce strength. They're also loud, a bit expensive, and can destroy your work if you're not careful.ĭriving slowly lets you keep control and reduces damage when the bit slips. As soon as a screw is damaged happens, if you pull the screw out before it gets worse and replace it, you'll be better off than if you keep driving the bad screw.Īn impact drill/driver makes driving screws much easier. ![]() More torque means more damage if it slips, so be careful if you turn up the clutch. If a driver bit slips out and damages the screw head, then you'll have a harder time finishing the work or removing the damaged screw. Cheap screws are more likely to break or round out the head. Square, aka Robertson is easier to work with than Phillip's, but not as nice as Torx & hex heads. They also continue to work well if they get dirty or are painted over. Torx, internal hex, and external hex are all easy to drive without much pressure and without cam-out. Make sure you know if your bits and screws are Phillip's or Pozidriv. With clutches on drivers today, the chances of over-torquing are greatly reduced. Pozidriv looks a lot like Phillip's, but has a subtly different shape that reduces cam-out. When the clutch slips, turn the clutch up and apply more pressure to finish the work. When the angle makes it difficult to apply pressure, set the clutch low and don't work too hard. Pressure on the drill is necessary to keep the bit in place. Keep the drill directly in line with the screw. Unlike flat-head are discrete, #2 being the most common. This is to prevent you from over-torquing the screw and damaging the work, screw, or bit. ![]() That is, when the screw stops turning easily, the bit is pushed up and out of the screw head. Phillip's head screws are actually designed to "cam out". Make sure your bit is properly aligned in the the slot. Fingernails, coins, and knives are non-optimal. ![]() Too narrow or too thin and you'll damage the head. Having a correctly-fitting bit helps a lot. Flat-head / slotted screws come in many sizes.
