Direct comparison of 2704-20, 2702-20 Hammer Drills and 2703-20 Drill/Driver.

Torque and speed

Milwaukee 2704-20 is our top recommendation for heavy-duty commercial drill/drive applications. With 1200in-lbs. and 32000BPM hammering speed, this hammer drill can handle any tough application you may have on-site. Its 24 points on the chuck allowing you to set both low and high torque for handling a wider range of applications. It needs muscle to handle the vibration at high toque but the auxiliary handle makes it easy to control by anyone. This is why it still makes a great impact driver for the toughest projects at home.

Milwaukee 2702-20 hammer drill on the other hand bridges all the difficulties of a heavy powerful hammer drill like 2704-20. It can be used by anyone without fatigue because of the gentle performance at the handle. It is a hammer drill loads 500lbs of torque which means it can only be used on light and standard applications. It has a powerful bit grip supported by the all metallic chuck. It also features 24-point chuck settings allowing you to regulate the torque even for the smallest screws.

2703-20 Is a hi-torque 18V cordless drill fitted with all the tough features needed for heavy-duty applications. It stores all the advantages of the 2704-20 hammer drill except for the hammering function. It has more runtime on regular batteries and longer motor life making it a one-time purchase. It is also versatile; it can be used on a wide range of drill/drive applications.

Battery life

The recommended battery for all these tools is M18 Redlithium battery series which retains the stable power output for long. 2704-20 hammer drill has a brushless motor that puts minimal strain on the battery giving you more runtime per single charge. Being a heavy-duty hammer drill, its optimal performance requires a 3AH battery or higher. This hammer drill is still safe to use thanks to the Red Link intelligence which senses overdrive automatically preventing damage to your screws saving the battery and the tool.

2702-20 is a light application hammer drill which retains a brushless motor. It can run perfectly on 2AH M18 batteries. It is also compatible with all M18 series batteries. 2703-20 also runs a heavy-duty motor which increases its battery consumption significantly. We recommend a 3AH set or higher amperage for the best experience when working.


High torque performance on a hammer drill or a regular cordless drill/driver leads to lots of vibration at the handle. This is the reason why most users need an auxiliary handle to retain full control at the bit when running a very high torque. 2704-20 and 2703-20 both come with an auxiliary handle making control easier. Milwaukee 2702-20 does not come with an auxiliary handle but its 500lb torque doesn`t shake the handle either making it easy to retain precision even at the highest torque.
