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 a 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.
