The CRL Glass Slicker is an innovative and inexpensive way to increase productivity and prolong cutter life. After filling the Slicker with W410QT Cutting Oil draw the Glass Slicker along the straight edge, the glass is wiped clean. At the same time, a thin film of oil is deposited on the glass. This helps to prevent "hot cuts" and skips resulting in a cleaner, smoother cut and break. Can also be used to lubricate panic hardware or hinge pins.
