Bosch EasyImpact Features

At a Glance Features:

Lightweight & Compact

This drill only weighs 1.5 kg and has been designed with an ergonomic design with a soft grip giving the end user maximum handling and control.

Keyless Chuck

This 550 model has a twin-sleeve keyless chuck, which simply means that bit changes are quick and easy and can be done using one hand.


This drill is versatile as it can be used for screwdriving and normal drilling, but also impact drilling. You simply ick the mode from a function switch.


This model has Bosch Electronic speed control using the trigger switch, and that allows fingertip control of the power, e.g. when starting to drill in smooth surfaces and when driving screws.

In Depth Feature Explanation

Keyless Chuck

Just about every brand of cordless drill/drivers uses a keyless chuck. This simply means that you can tighten the chuck by hand, which makes for fast drill bit and screwdriving bit changes.

This Bosch Easyimpact uses a twin-sleeve keyless chuck that makes bit changes quick and easy without the need for any other tools. It does require the use of both hands to release and tighten the chuck.

The chuck capacity on this drill/driver is 2 - 13 mm.


When you see "torque" mentioned on a cordless drill/driver, it refers mainly to the screwdriving features of the drill. Torque really means the force or pressure at which the drill operates. Imagine you were driving screws into a hard wood, that would require a lower speed and more torque than if you were drilling soft wood. 

Having the right torque setting selected helps you to control the depth of your driving. Over driving screws will happen if the torque is too high and may cause wood to split. Not enough torque and the screw will struggle to go in.

The other issue that setting the right torque accomplishes is not stripping the head of the screws. Again if the torque is too high it will strip the head, and even if too low can also cause stripping.

Torque is measured in newton-metres. For drill/drivers the following is a very good guideline:

  • 4-15 Nm - ideal for smaller driving tasks and soft wood
  • 15-30 Nm for medium screw sizes
  • 35Nm+ for longer or larger screws

So at a setting of 1 the torque will be very low and at 20 will be high.

Different torques are used for driving through different materials.

This Bosch 550 model has a rated torque of 1.2 Nm. It also has a no load speed ranging from 50-3,000 RPM. The impact rate of the hammer feature is 33,000 bpm, which is one of the highest hammer drilling rates available.

Our Verdict on the Bosch EasyImpact 550 Hammer Drill

Bosch have designed this drill as a lightweight and compact design. That along with the soft grip handle make this model comfortable and easy to use.

It is versatile and can be used for screw driving, drilling or hammer drilling into materials such as wood, metal and masonry. That does make this a very good all rounder for using in the home, workshop or in the garden.

It's exceptionally comfortable and easy to handle, providing a solution to any drilling task around your home. It also comes with a user manual.

This corded drill is part of the newer range of Bosch drills and sells really well on the UK market.

The fact that there are over 2,000 online buyer reviews is proof that it sells really well. That information along with a 94% buyer satisfaction also shows that buyers really rate this drill very highly. The number of complaints are really minor complaints and also very low, which is always a very good sign.

The only word of caution we would offer is about heavy concrete drilling. Most heavier duty hammer drills use a keyed chuck to tighten the chuck. That ensures that the masonry drill bit is held in place and doesn't slip. This model uses a keyless chuck, and although that makes changing bites easier, they are prone to loosening.

That happens when under a heavy load such as drilling a wall. Any complaints there are about this drill are about the chuck slipping when drilling masonry. It will still get the job done, but can also be frustrating.
