What Does The Numbers On A Drill Mean

You’ll see a list of numbers from 1 to 10 or 20. These are used to set the clutch to deliver a torque range. The higher the number on the collar, the higher the torque and the larger the fastener that can be driven. To adjust your clutch, align the arrow to a lower setting and start driving a screw.

What is a good torque for cordless drill?

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. 35Nm upward will tackle all of those more serious project with bigger screws and holes.

What do numbers on power drill mean?

In simple words, the numbers on your drill refer to how much torque will be applied to a fastener such as a screw. Once that particular torque level is reached, the power drill will stop driving the fastener or turning at all.

What is the torque setting on a drill?

Most of understand speed, it’s how fast the drill rotates the bit. The torque is how much muscle it can apply to that speed. Speed is required to drive the screw, but torque is what allows it to keep going when it needs to fight the stopping force of friction.

What do the numbers on top of a drill?

The numbers on a drill driver refer to the amount of torque the drill will apply to a fastener (usually a screw) and once that torque setting is reached, the drill will stop turning/driving the fastener.

How do I choose my drill speed?

Determining Drill Speed Determine the size of the hole you need to drill into the material. Decide what is more important: getting the job done faster or preserving the life of the drill bit. Begin on a slow RPM setting and test out the bit. ALWAYS (especially at high speeds) pay attention to the material.

Are cordless drills worth it?

A cordless drill is the most essential power tool you’ll buy. It’s the one you’ll rely on for big projects, such as building a deck and remodeling a kitchen, and for smaller tasks, like installing fixtures and assembling furniture. You might even need your drill to service other tools.

What are the numbers on a drill chuck?

You’ll see a list of numbers from 1 to 10 or 20. These are used to set the clutch to deliver a torque range. The higher the number on the collar, the higher the torque and the larger the fastener that can be driven. To adjust your clutch, align the arrow to a lower setting and start driving a screw.

What is the best voltage for a cordless drill?

A cordless drill offers high mobility and a wide range of available features. Voltage ratings of 4 to 8 volts are sufficient for light-duty cordless screwdrivers, and drills with 12 to 18 volts will meet most homeowners’ work needs.

How do you read a DeWALT model number?

The model number is usually found at the top left part of the name plate. In this case the model number is DW938. When DeWALT comes out with the first version of a tool, it is usually a Type 0 or a Type 1. (Occasionally the first version will not have a type, but this is rare.).

How much torque does a Dewalt drill have?

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.

How much torque does a Dewalt 20V drill have?

impact driver, two 20V MAX* lithium ion batteries, charger, and carrying bag. At only 5.1 in. front to back, the impact driver features a high-performance brushless motor that delivers 1700 in-lbs of torque and 3 LEDs for optimum illumination as you work.

Are the numbers on a drill foot pounds?

They are just a guide. If you are drilling the numbers are meaningless and you could set the drill to its highest or locked position. The numbers matter when you are using the tool to insert screws.

What is the clutch on a drill?

These days, manufacturers provide a clutch on cordless drill/drivers with numeric settings on the collar. Its purpose is to disengage the transmission at a range of torque thresholds to prevent overdriving screws in delicate surfaces such as drywall, or damaging small or fragile screws.

What is hammer drill used for?

A hammer drill delivers more power in the form of a hammering action. The force of the hammer drill is applied directly to the bit. They are most commonly used for drilling in concrete and masonry. The hammering portion of this motion can be turned off, allowing the tool to function more like a standard drill.

What is drill chuck?

Drill chucks are devices used to hold a drill or other cutting tools on a spindle. They are available in keyed, keyless or hybrid systems, allowing for quick changes of a drill bit. Keyed chucks are engineered to either loosen or tighten the hold on a tool by using a key.

What is considered a high speed drill?

Guhring uses “high speed drilling” to refer to drilling at spindle speeds high enough to permit penetration rates of three to ten times the conventional rate, as dictated by the workpiece material.

Does a smaller diameter hole require a higher rpm?

The short answer is that the cutting speed in feet per minute should be the same regardless of the size of the hole. To achieve the same cutting speed in feet per minute, the rotational speed must be lower for larger diameter drills.

Why do drills have two speeds?

The high-speed setting is intended for drilling, while the low-speed setting generates more power for tough screw-driving jobs.
