Choose the Correct Fit
Match the blade diameter, arbor and maximum speed to the saw. Use only the specified flanges, guard and approved arbor configuration.
Identify the material before cutting. Plan silica-dust controls and support the work so the kerf cannot close on the blade.
Installation & Care
Disconnect power before fitting the blade. Keep the correct guard and flanges installed, and direct sparks away from people and combustible materials.
Use a straight, controlled feed without side loading. Let the blade cool and inspect the core and cutting edge for damage before reuse.

Important Product Questions
Is this a concrete diamond blade?
No. STEELHEAD is engineered for metal and stainless materials. Choose a masonry-rated diamond blade for concrete or stone.
Can I wet cut with this blade?
This STEELHEAD blade is specified for dry use. Follow its label and the tool instructions rather than adding water.
Does maintaining diameter mean unlimited blade life?
No. The edge still wears. Replace a damaged or worn blade and stop if cutting performance falls or abnormal vibration appears.
