OK so... The 115 has the handle and has lower RPM
BUT WHY are the internal parts different?
The 114 has several motor protection features.
SO WHICH IS BEST?
SECOND QUESTION:
CAN THE 5-6" HAND GRINDER USE THE 4.5" WHEELS?
THIRD: WHICH IS MORE POWERFUL AND LONGER LASTING...... 5-6" MODELS OR 4.5" MODELS?
