After I put this mallet face replacement to the test I was blown away by its durability and functionality. The design and materials used ensure that this mallet face can withstand even the toughest jobs without causing any damage to the tool .It perfectly fits onto my existing mallet, making it a convenient and affordable replacement option..
These are OEM and fit perfectly. I clamped the old bumper in a vise and used the handle as leverage to simply pull up and twist to remove. The installation required a little more effort. I had to carve a small bevel on the iron face of the hammer head and use some lube to thread the new bumpers onto the hammer head. Secure the piece of iron in a vise so you can use your body weight to assemble the bumpers.
