It is a well-designed impact driver that some users find a bit on the long and bulky side, measuring 9 x 3 inches.

This is especially crucial for working in tight and confined spaces. Its weight is 1.3 pounds without the battery. Its excellent balance lets you work longer without straining your arms or injuring your hands and wrists.

It has a quick release ¼-inch head hex chuck that allows you to quickly and easily change bits with just one hand. This is one feature you will find that adds a nice touch to this impact driver.

Bit replacement can be done without having much fuss, so you can swiftly and easily pop in a new bit without thinking twice about it.

Added Features

This impact driver uses a 20V lithium ion battery that provides you with hours of comfortable work time. The battery has a 1.3 Ah capacity which is less than the regular capacity of 1.5 Ah of other models. This means that the battery pack can deliver a steady 1.3 amps of current for one hour of runtime.

But of course you do not run the power tool continuously for one hour, do you? This is just a minor flaw that you will soon forget once you get the job done efficiently with this impact driver.

Another very useful and smart feature of the Porter-Cable PCC641 is the built-in LED light that conveniently illuminates your workspace.

It is perfect for working in poorly lit spaces or when working at night. Along with its light build, this is very suitable for working in those hard to reach areas like overhead spaces and the insides of a shelf or cabinet.

On the impact driver are two magnetic bit holders located on the top of the motor and a clip on the base of the battery slide. This tool can hold three bits all at the same time.

Like most Porter-Cable power tools, this impact driver is covered by a limited warranty for any defects due to faulty materials or workmanship for three years from the date of purchase. As all warranties, this does not cover parts failure due to normal wear and tear or tool abuse or misuse.

Comparison with Porter-Cable PCCK647LB

The Porter-Cable PCCK647LB and PCC641 impact drivers differ in many of their specs and features.

Each one has something better to offer than the other, but both can perform well in the right circumstances. It is recommended to look into these two closely to see which one is better suited to your needs.

The PCCK647LB has a brushless motor that gives you 50% more runtime than the PCC641 which uses carbon brushes in its motor. The latter has 1,450 in. lbs. of torque while the former only has 1,400.

There is very minimal difference, but if the price is one of your considerations, then go for the PCC641 with its lower price tag as compared to double the cost of the PCCK647LB.

This price difference is because of the components included in the PCCK647LB’s kit. It comes with lithium ion batteries, a charger, and one screw driving bit.

On the other hand, the PCC641 is sold as a bare tool at Amazon, the batteries, charger, and other accessories are sold separately. You only get the drill which may be well the reason for its very low price and not because it performs poorly.
