DeWalt is another brand renowned for well-made, professional-standard power tools. Its 20V drywall screw gun has a brushless motor with a speed of 4,400 rpm. At 2.7 pounds, it is a fraction heavier than the Milwaukee, though the batteries are lighter, so the all up weight difference is negligible. The tool has a soft-grip handle and good ergonomics.

Weight will make a considerable difference to those who are hanging drywall all day, especially if installing ceilings. A comfortable grip and an easy-to-reach trigger will also reduce fatigue and help prevent hand cramps. Key features are the adjustable screw holder that securely grips the screw while driving and frees up one hand. A thumb-operated bit changer rotates easily to any of six preloaded bits that then slide into place, ready for use.

It’s part of Makita’s expanding 18V Lithium-Ion system, the world’s largest cordless tool system powered by 18V Lithium-Ion slide-style batteries. Makita 18V Lithium-Ion batteries have the fastest charge times in their categories, so they spend more time working and less time sitting on the charger. An important feature of most drywall screw guns is the nose cone, which surrounds the gun’s screwdriver bit. As the screw is driven into the drywall sheet, the nose cone provides a depth stop, so the screw head is sunk just below the surface (to be hidden by filler), but not driven too deep. The BL™ Brushless Motor eliminates carbon brushes, enabling the BL™ Motor to run cooler and more efficiently for longer life Push Drive™ Technology delivers increased efficiency, longer run time and lower noise for drywall fastening . With Push Drive™ the motor starts only when the fastener is engaged with the work piece, so battery power is used more efficiently for significantly longer run time. Contractors benefit from less downtime charging batteries, and from a quieter work environment since the motor runs only during fastening.

While cordless drywall screw guns tend to be the more popular choice, DeWalt’s high-speed corded model has a range of features that make it an attractive option for those who want strong performance with minimal outlay. The brushless motor runs at 4,000 rpm and can drive collated screws (drywall and standard wood screws) from 1 inch to 2.125 inch long. Instead of the usual three-step depth setting, there is a variable dial. This gives the Makita auto-feed screwdriver great versatility and allows the user to compensate for the hardness of the material and set the depth precisely. Makita DFR550Z LXT Li-Ion Cordless Auto feed Screwdriver 18v gives high operation efficiency delivered from fast rotational speed and improved screw strip management. Has Makita's new silent clutch featuringdirect drive transmission in reverse rotation. Also now with a more reliable casing attachment which can be removed or attached without a tool. The 424mm long machine has an ergonomically designedrubberizedgrip with anti-slip to provide a steady hold in all conditions. DFR550ZFeatures: The main thing that restricts working speed when hanging drywall, even with auto mode, is the need to load each drywall screw individually. The fix for this is either a collated screw attachment or an auto-feed gun.Rapid Optimum Charger communicates with the battery's built-in chip throughout the charging process to optimize battery life by actively controlling current, voltage and temperature
