As mentioned at the beginning of the article, the numbers on a drill represent the amount of torque the tool can apply to an object (such as a screw) or for hole drilling. The numbers usually range from 1 to 20 (or more) with 1 representing the least amount of torque and 20, the greatest.
What do the different speeds on a drill mean?
Generally, the higher speed and lower torque range is used for smaller diameter drilling tasks, and the lower speed and higher torque range for larger bits and tougher tasks. The lower speed range is also usually better for driving and fastening tasks. Some accessories typically have maximum speed ratings.
What does torque on a drill mean?
Torque is the force the drill produces to turn an object, not how fast an object will turn.
What is setting 1 and 2 on a drill?
The adjustable gearing provides versatility based on the task you will be performing. Setting 1 is low speed/high torque and is best for driving screws. Setting 2 is a medium speed/torque and can be used for drilling or driving. Setting 3 is the highest speed and is meant for drilling or driving fasteners.
Which torque setting to use on drill?
The more settings the finer your control while working. Newton Metres (Nm) on drills: 4 to 15Nm is fine for all of those smaller screw driver tasks around the home. 15 to 35Nm is a great all-rounder to drill and drive medium sizes screws and hole drilling.
What drill speed should I use?
The best speed for drilling wood depends on the diameter of the bit and the material drilled. Larger diameter bits require a slower speed, as do hardwoods. Drilling into softwood with a twist drill bit up to 3/8″ in diameter requires a speed of 3000 RPM, while the same bit with hardwood requires 1500 RPM.
How do you know what speed to drill?
Feed equals . 001″ per revolution for every 1/16″ of drill diameter, plus or minus . 001″ on the total. Speed equals 80 surface feet per minute in 100 Brinell hardness material and the speed should be reduced 10 surface feet per minute for each additional 50 points Brinell hardness.
What is torque setting?
What is the torque setting for (the rotating ring with figures)? This setting lets you control the torque or turning power of the drill driver. The higher the torque (number on the torque ring), the more ‘power’ the drill driver produces and the deeper the screw can be driven into the workpiece.
What do drill bit numbers mean?
Number and letter gauge drill bit sizes
Number drill bit gauge sizes range from size 80 (the smallest) to size 1 (the largest) followed by letter gauge size A (the smallest) to size Z (the largest).
What is hard and soft torque?
So, the difference between hard torque and soft torque is this: Hard torque is how much the driver will produce when you’re working with hardened fasteners and materials like stainless steel. Soft torque is the maximum torque you get when you’re working with softer materials, like pine.
What are the 2 speeds on a drill?
Mechanical speed setting
When a drill has 2 speed settings, the RPM is indicated twice as well; once for the lower gear (low RPM) and once for the higher gear (high RPM). Rarely, you’ll find more than 2 gears on a drill. In these cases, you’ll have even better control over the machine’s speed.
What setting to use to drill into brick?
Top Tips to Remember When Drilling Into Brick
When drilling brick, ideally you want to use the slowest possible speed that will get the job done.For soft masonry, use the slowest speed setting and don’t turn on the hammer action, but for hard masonry, choose a slightly faster speed and activate hammer action.
What is hammer mode on a drill?
Hammer mode overrides the torque adjustment and introduces a pulsating action that helps to force masonry bits through concrete, brick, and stone. Drill mode overrides the torque adjustment and delivers maximum torque to the bit. This ensures that the drill will not clutch out during drilling.
What are the torque settings on a Dewalt drill?
One drill is rated at 400 in-lbs max and with 0-400/0-1500 RPM speed settings, and another at 380 in-lbs max torque, with 0-550/0-2000 RPM speed settings.
