- You only sharpened your blade with one pass (creating blocky teeth) - Incompatible blade material - Incorrect drill speed/pressure - Not using the Sharptool correctly - blade that is too damaged to recover - Manufacturing fault
Start with these checks:
(1.) Confirm the blade is compatible SharpTool 2.0 is designed for sawable multitool blades made of HCS, HSS, BIM, and titanium-coated blades. Carbide blades are NOT suitable, Carbide is harder than the sharpening head and can wear it down while removing the carbide edge.
(2.) Use correct sharpening technique: Attach SharpTool 2.0 to your drill. Start at low speed and use light pressure, let the CBN head do the work. Sharpen in 2 or 3 passes depending on what you want to cut
(3.) Prevent overheating (heat kills results) Overheating reduces cutting performance and increases wear. Sharpen a maximum of 1 blade per minute and let the blade/head cool down fully.
(4.) Inspect the blade condition (some blades cannot be “saved”) If the blade is cracked, bent, missing chunks/teeth, or heavily corroded, replace it. Damaged blades can break and are not worth sharpening.
