Chiseling and Chipping
These MILWAUKEE Hammers may be used for chipping and chiseling.
When chiseling, hold the tool at an angle to the workpiece. Work from a
corner or close to the edge of the workpiece, breaking off one small area
at a time rather than attempting too large an area.
A variety of accessories are available.
Scaling Chisels
For removing weld spatter or scale and cut-
ting straight lines.
Bushing Tools
Used to surface concrete.
Mortar Cutting Chisels (Seam Tools)
For removing old mortar for tuck pointing or
caulking.
Bull Points
For demolition work and starting holes in
concrete slabs.
Flat Chisels
For edging, chipping or channeling.
Slotting Chisel
For slotting and cutting between drilled holes
in concrete and masonry.
NOTE: If unable to drill a hole in the kerf, pull back on the bit with the ham-
mer running (Fig. 13). This will remove some of the dust and debris from
the cut. Repeat this for every inch of drilling. If necessary, vacuum dust and
debris from the cut and surrounding area.

Pull bit out as far
as possible once
or twice per inch
drilled.
7. For core bits, once the maximum core bit depth is drilled, the core must
be broken and removed.
• Install a chisel bit.
• Place the chisel into the hole kerf (Fig. 12).
• Chisel down into the kerf at several points until the core is loose or
broken.
• Remove the core and vacuum/remove any remaining dust and de-
bris.
• Install the core bit and continue the cut.
