Hilti impact driver review: In Part 6 of our mega Impact Driver roundup, Roger puts the Hilti SID 4-A22 Impact Driver to the test.
The new SID 4-A22 Cordless impact driver is designed for high torque applications because, Hilti says, sometimes a standard drill driver simply won’t cut it – you need more impact to get the job done.
With an improved 194 Nm torque, this lightweight and compact tool is pitched to really pack a punch. The SID 4-A22 has undergone a complete redesign to replace the earlier 22 V impact driver.
Hilti says this new tool comfortably delivers more productivity, improved handling and is built to last.
Hilti has re-designed the hammering mechanism to make SID 4-A22 even faster than its predecessor and improved the trigger so it’s more responsive than before.
Better ergonomics and balance, together with reduced size of the tool body improves handling and working comfort.
Built to last
With a robust casing and improved chuck the SID 4-A22 is robust enough for even the harshest site conditions.
