3 New Makita Grinders Feature X-Lock Quick Change System
For those of you in the know about the quick convenience that the X-Lock System provides, or for anyone who just gets excited about advances in angle grinder technology, prepare to get jazzed. Makita has announced a line of angle grinders that use X-Lock accessories.
What’s the Big Deal About X-Lock?
Our first experience with this technology came from seeing the Bosch X-Lock grinder at World of Concrete. X-Lock is an accessory locking mechanism that is integrated into the gear housing for tool-free accessory changes. It includes a click-mount and pull-release lever. Combined, they make changing out wheels and accessories up to 5 times faster than traditional threaded lock-nuts. Not only does it eliminate looking for a wrench when you need to change out a wheel, but it also eliminates the possibility of over- or under-tightening the threaded lock spindles.
Additionally, X-Lock wheels are backwards compatible with standard 7/8″ arbors. This means that you can generally buy one set of accessories for use with all of the grinders on site.
It should be noted, however, that the Makita X-Lock Grinders will only work with X-Lock accessories.
Makita X-Lock Angle Grinders
In addition to the wheel change system, Makita X-Lock angle grinders have been designed with faster grinding in mind. Both cordless models use a brushless motor that provides 8,500 RPM. Spiral bevel gears deliver smoother rotations and a more efficient transfer of energy for more consistent grinding.
In addition, both of the 18V X-Lock angle grinders feature the following technology:
- Automatic Speed Change – automatically adjusts your speed and torque
- Active Feedback-Sensing Technology (AFT) – turns off the motor if the rotation suddenly slows or stops
- Anti-Restart Protection – prevents motor startup when a new battery is inserted while the switch is set to “On”
- Extreme Protection Technology (XPT) – protects the tool from dust and moisture
- Soft Start – promotes longer motor life
- Star Protection Computer Controls
The Makita GA4570 corded grinder offers a 7.5-amp motor with an AC/DC slide switch that allows use with alternative power sources. Makita designed this compact tool with a 2-1/2″ diameter barrel. And, for durability, it uses a ball-bearing design and metal gear housing, plus a series of protective seals and varnish-sealed armature.
