Festool’s TID 18 takes a different approach than the high-torque monsters most contractors carry. This impact driver prioritizes smooth, controllable operation over peak torque numbers — and that’s exactly what finish carpenters and cabinet installers need. At 1,593 in-lb of torque, it won’t win any power contests against flagship models from Milwaukee or DeWalt. But the EC-TEC brushless motor delivers that power with less vibration and more finesse than typical contractor tools.
The weight tells the real story. At 3.3-4 lb with battery, the TID 18 stays manageable during overhead work and repetitive fastening. The T-mode function starts at 3,200 RPM then automatically drops to 750 RPM when transitioning — perfect for delicate operations where a standard impact driver would overdrive fasteners. Three standard speed settings (0-1,200, 0-2,000, and 0-3,200 RPM) handle everything else.
Frequently Asked Questions
Q: What makes the Festool TID 18 impact driver different from contractor-grade models?
The Festool TID 18 delivers smoother and more controllable operation than typical high-torque contractor tools, though it may have lower peak torque than some flagship models. It features a brushless EC-TEC motor and weighs only 3.3-4 lb with battery, making it lighter than most professional impact drivers while still producing up to 1,593 in-lb of torque.
Q: What comes with the Festool TID 18 HPC 4.0 set?
The HPC 4.0 set includes the TID 18 impact driver, two BP 18 Li 4.0 HPC-ASI Bluetooth batteries, a TCL 6 rapid charger, a belt clip, and a Systainer3 SYS3 DF M 187 storage case. The Basic version contains just the tool without batteries or charger.
Q: How long is the warranty on Festool power tools?
Festool offers a 3-year all-inclusive warranty that covers wear-and-tear items and repair service for 36 months. You must register online through the MyFestool portal to activate the warranty coverage.
Q: What’s the T-mode on the Festool TID 18 and how does it work?
T-mode on the TID 18 starts at 3,200 RPM then automatically drops to 750 RPM when transitioning, providing better control for delicate fastening operations. The impact driver offers three standard speed settings (0-1,200, 0-2,000, and 0-3,200 RPM) plus this specialized T-mode for precision work.
Q: Will Festool 18V batteries work with older Festool tools?
Festool maintains backward compatibility across their 18V Li-HighPower battery platform (BP 18 Li series). The batteries connect via a standard slide-on interface that works across Festool’s 18V tool range.
Q: What are the SELFCLEAN filter bags for Festool dust extractors?
The SC FIS-CT SYS/5 SELFCLEAN filter bags are made of highly tear-resistant fleece material designed for the CTL SYS dust extractors. They’re rated for dust with limit values above 1 mg/m³ and optimize the usable filter bag volume, sold in packs of 5.
