The Makita XFD11R1B is an updated one-battery kit for the XFD11ZB sub-compact brushless driver-drill. The BL brushless motor delivers 350 in-lbs of max torque in a 6-3/8 in., 2.8 lb package ideal for tight-space applications. A 2-speed gearbox (0–500 / 0–1,700 RPM), 20-position clutch, Extreme Protection Technology (XPT), and dual LED lights round out the feature set. Includes one 2.0Ah battery and rapid charger.
What is the 'R1B' vs 'RB' distinction in the model number?
The R1B designation indicates this is the revised (first update) of the RB kit configuration. Both include one 2.0Ah battery and a rapid charger with the same XFD11ZB drill. Makita uses numeric suffixes to distinguish kit revisions; functionally, R1B and RB are identical in drill performance.
Is the XFD11R1B discontinued?
Yes. Makita has discontinued the XFD11R1B. The current sub-compact brushless kit successor is the XFD15SY1B or equivalent XFD15 series, which continues the sub-compact platform with updated specifications.
What is the XFD11ZB's weight advantage over a standard LXT drill?
The XFD11ZB weighs 2.8 lbs with battery, compared to 3.3 lbs for the XFD10Z and 3.9 lbs for the XFD12Z. That half-pound to full-pound reduction is significant during extended overhead work, in-ceiling electrical runs, or repetitive fastening in tight spots. Brushless efficiency also reduces heat buildup during sustained use.
