The new AG 4S-A22 cordless angle grinder raises the bar for speed and handling

Whether cutting rebar, tubes or sheets, deburring, surface cleaning or removing welds, it requires steady grip to get a good result. The slim, light and balanced AG 4S-A22 is designed to sit firmly in your hand – giving you the responsive handling you need. 

Suitable for a broad range of materials


Carbon steel

Stainless steel



Versatile, flexible and powerful

The new AG 4S-A22 cordless angle grinder is the perfect addition to your workbench, it's fully compatible with our range of 22V batteries and chargers and can be used with all existing cutting and grinding discs up to 125 mm.

Speed control for working with stainless steel

The AG 4S-A22 cordless angle grinder includes a 6-step speed control letting you select the disc rotation speed, from 3,500 - 8,000 rpm, to match the needs of your technique, application and materials. This is especially important when working with abrasive inserts on stainless steel (inox), where the speed dial can give you precise control of the abrasiveness.

The AG 4S-A22 cordless angle grinder has an optimised airflow system allowing it to cool down, which increases the lifetime of the tool. As you'd expect, all Hilti cordless tools come with 2 years of wear-and-tear coverage and, if your tool does break, we’ll repair it within 3 days – all at no cost, giving you complete peace of mind.
