Selecting the Right
Abrasive for the Job
About WORK SHARP™ Abrasive Technology
Finish
• Coated abrasive disks start flat and stay flat. (Bonded abrasives used
in stones and most power systems require frequent dressing to keep
the wheel flat.)
• Heat treated aluminum oxide and ceramic abrasives provide a pol-
ished finish superior to oil and water stones without the mess.
• Premium P-graded Abrasives provide more consistent cutter height
and smoother surface finish than traditional bonded and plated abra-
sives. (As bonded wheels wear they tend to round the edges/corner
of the tool. As the abrasive particles wear, the bond breaks down,
exposing new particles but always at a different depth.)
• The grit size is engineered to provide optimal sharpness and surface
finish at each stage of sharpening. (Users who are interested in a
“utility sharp” edge will find exceptional edge performance on the
faster coarse grits without the need to hone.)
Speed
• The abrasive selection is integrated with design of the WORK
SHARP
®
drive train and cooling system to provide the fastest materi-
al removal rate while minimizing the risk of overheating tool steels.
• The sharpening port includes a lapping abrasive that provides supe-
rior burr control and allows for 1-step re-sharpening.
• Two-sided wheel and off-the-shelf abrasive makes it easy to switch
between coarse and fine abrasives. (Doesn’t require re-grading the
wheel just to switch between coarse and fine Abrasives. Doesn’t re-
quire an expensive selection of custom wheels or disks.)
Simplicity
• Accepts standard 150 mm or 6" PSA-backed adhesive that is read-
ily available. (No custom adhesives or expensive custom wheels re-
quired. Coarse grits are available at most hardware/woodworking
stores. Fine grits are readily available at any automotive paint sup-
ply store.)
• Abrasive disk life can be extended significantly by regular cleaning
using the supplied disk cleaner (Crepe Stick). Simply rub the Crepe
Stick across the surface of the Wheel to remove any loading or build-
up on the Abrasive.
