Don’t sink screws too close to the area where you will be making the cut. Fasten too closely, and the pressure on the sheet can tear the paper face as the cut is finished. Finish fastening after completing all cuts.

Face milling is a type of CNC milling process―which means it involves removing portions of material from a workpiece using cutting tools.

The primary feature of the Tamiya 72004 Worm Gearbox from Tamiya’s high-efficiency series is a worm gear, which locks the output shaft whenever the motor isn’t turning. The high gear ratios of 216:1 or 336:1 make this gearbox appropriate for small walking robots, lifting mechanisms, and other applications where high torque is desired.

Straight bits are good for making mortices for cabinet and furniture making. The round over bit is normal sized and big enough to use for a 3/4" table top, and ...

The tip of a drywall bit is smooth, so it can bear on the edge of whatever you’re cutting and guide the cut. Set the bit depth so that the smooth section will be about 1/8 in. beyond the back of the drywall.

Slow the cut near corners, pushing the bit lightly against the object so that it turns as it reaches the corner. If the router stops moving easily, you may have hit a nib on an electrical box or a projecting piece of extension jam. Gently move the bit around the obstacle, then cut on.

Still, every drywall pro I knew used a router to make quick, clean, and accurate cuts. There had to be something to these tools. They don’t cost a lot either (about $60 to $110), and the bits are only a buck or two each. Tool use usually comes easily to me, so my failure with drywall routers was both out of character and frustrating. And I wasn’t alone; many carpenters I’ve talked with are buffaloed by these tools.

PVD stands for Physical Vapour Deposition, which is essentially an ionic plating process in which the surface of the part is coated with a very hard metal.

Note: The worm gearbox is a kit; assembly is required. To use the kit in robotics projects, you need to connect the motors to your own robot controller.

Push on the sheet with your hand or knee so that the drywall is tight to the object you’re cutting around. Turn on the router, and push the bit through the drywall.

This gearbox has a 4 mm diameter, round output shaft, which works with the wheels that are compatible with Tamiya 4 mm, round shafts. Our 3 mm universal mounting hub also fits on the smaller threaded end of the shaft, although it is not specifically intended to work with this type of shaft (the hub’s set screw could damage the thread on the shaft).

This is not the easiest method. this is the perfect tool for the job. https://amzn.to/2V0Hv01 a Qbit attachment for your multitool I've pasted a link to the Low Voltage Qbit but they also have double-gang and a slightly larger one for electrical boxes.

Unlike recessed lights, electrical boxes, and windows with jambs that extend beyond the stud faces, rough openings are cut from the inside. Set the bit deeper so that the tip clears the eased edges of framing lumber, and cut clockwise.

When faced with a big project of my own, I decided to take the time and figure it out. After a few missteps, I’m cutting holes in drywall faster and more accurately than ever. What I learned is summarized below. And if you want to get a sense of how others builders have tackled this problem, you might try FHB’s Discussion Forum where builders have discussed both equipment and technique.

Move the router outward until the bit hits an edge of what you’re cutting around. Pull the bit out, then reinsert it on the other side of the edge.

After a few early failures, I avoided using a drywall router to cut holes for electrical boxes, lights, windows, and doors. In theory, it should be simple: you hang the drywall, make a plunge cut with the 1/8-in. self-guided helical bit, and follow the edge of whatever it is you want to fit the sheet around. I’d tried one on a few occasions, with results such as mangled wires and wandering cuts. I reverted to doing things the carpenter’s way: laying out the holes with a square and a tape measure, then cutting them with a knife and a keyhole saw. This was slow, but at least I was on familiar ground.

No-Fall Drywall – Making a wiggly line with your router is the key to keeping a piece of drywall from slipping before it’s fully cut.

Electrical boxes are the most common target for a drywall router, and that spinning bit can do some serious damage to wires. Make sure the power to the box you’re cutting around is off, and push wires to the back of the box.

Moving in this direction requires only light pressure to follow the edge of the box because the bit rotation pulls it inward. If you cut in a clockwise direction on the outside the rotation will push the bit away from the box, causing you to overcut.

The RotoZip is the granddaddy of drywall routers, so much so that the job-site term for a drywall router is a RotoZip. A number of companies now make drywall routers, however, and there are even cordless versions, such as Makita’s XOC01T, which I tried out on an earlier job. Both tools have their place. The RotoZip has more power, and because it’s corded (the 6-ft. cord could be longer; drywall screw guns come with 16-ft. cords), there isn’t a battery to run out of power, which makes it a better choice on a larger project. On the other hand, the Makita has enough power, the batteries have plenty of life, and not having cords to trip over is hard to overrate, particularly on remodeling jobs in tight spaces. Both tools use the same 1/8-in. helical bits that guide the cut by riding on whatever you’re cutting out. In addition, there also are corded and cordless models from DeWalt, a cordless model from Milwaukee, and a cordless model from Ryobi.

For cuts near an edge, mark the abutting sheet. For middle-of-the-board cuts, mark the center of the cutout before hanging the board. This is a starting point and a reminder that something is there to cut around.

The low-voltage motors in the worm gearbox run on 1.5-4.5 volts and draw up to a few amps, making them perfect candidates for the DRV8833 motor driver carrier. Motor overheating can be caused by excessive stalling, even at very low voltages. We recommend that you use stall-detection sensors, or just watch your robot, to make sure that it doesn’t stall for more than a few seconds at a time.
