Is it Worth Upgrading From The DTD154 to DTD171? BL motor efficiently uses energy to match torque and RPM to the changing demands of the applicationBoth Makita impact drives have the same impacts per minute at 3,800 and no load speed at 3,600. It’s quite disappointing that Makita did not increase these in the DTD171, however, 3,800 IPM and 3,600 RPM is still very good. Brushless Motor Extreme Protection Technology (XPT) is engineered for improved dust and water resistance for operation in harsh conditions This is where you begin the notice the differences between the two 18v Makita impact drivers.

Bolt Mode – This mode helps stop run off. When unfastening bolts and nuts, the impact driver can detect when the bolt is loosened and stops. stage impact power selection mode variations impact power selection that lets you control it to suit a variety of applications. The special modes change the impact ratios and speed to allow for various impact characteristics. You also get the The A-Mode is designed to eliminate screw cam-out and cross threading caused by high speed rotation before the screw bites in the material.

BL motor is electronically controlled to optimize battery energy use for longer run time per charge This Makita impact driver is compatible with Makita LXT 18v battery range, if you already have LXT batteries, you will only need the body which is the DTD171z. This is currently the best Makita impact driver. 4x Assist Mode & 4 Stage Impact Power Selection
