While the conventional
wisdom surrounding carbide saw blades
reserves sharpening for industry professionals, more and more individuals are
choosing to touch up and care for their own blades at home. While most starter
sets for sharpening can be purchased for $100 to $500, with fully professional
kits nearing $5,000 in cost, anyone with a working Dremel tool and diamond
paddle hone attachment can learn the basics of finishing and sharpening carbide
saw blades.
Instructions
1. Decide on a working area
with ample lighting for the cleaning and sharpening of your saw blade. Make
sure that the working surface is clear of any dirt, dust or other debris.
2.Fill the basin or other
water container with hot water while adding copious amounts of the citrus oil
soap. Continue adding soap until the water surface is thick with soapsuds.
Submerge each dull carbide saw blade in the basin and let it soak for 15 to 20
minutes. Once dry, carefully lift each blade and scrub out any resins or
trapped oils between the blade teeth using a small brass-bristled brush. Repeat
for each blade before rinsing the blades in hot water and setting them out to
dry.
3.
Insert the
diamond paddle hone attachment into the nozzle of the Dremel tool and wet the
tip in soapy water. Put on your safety gloves and goggles and turn on the
Dremel tool at a medium setting. Apply the wetted paddle hone tip to the flat
steel sides of your carbide saw blade, re-wetting the tip if sparks occur.
Continue finishing the saw faces until both blade surfaces display a uniform
sheen and color.
4.
Hold the blade
vertically in one gloved hand to position the saw blade for sharpening. Re-wet
the paddle hone by dipping the tip in soapy water once more before carefully
inserting it against the flat "leading" face of one of the carbide
teeth. Turn on the Dremel tool to medium setting and apply the wet hone to each
face of the carbide teeth, making sure not to
round out the sides of the teeth as you work. Gently touch the tip of each
tooth with the paddle hone to aid in cutting. Repeat for each of the carbide
teeth until the blade has been entirely sharpened with the wet paddle hone.
5.
Rinse the
completed blade in hot water and let dry before returning it to the saw. Repeat
the process for any other carbide saw blades that require sharpening.
