The new IRWIN WeldTec Circular Saw Blades are precision engineered to deliver long life and durability without sacrificing speed of cut. Made in Italy, these blades feature exclusive welded carbide teeth for industry-leading strength. The heat resistant non-stick coating reduces binding and gumming so the blades run cooler and and deliver cleaner, truer cuts. Plus, the blades are laser cut with expansion control slots to reduce warping and vibration. The new blades are available for Construction, Demolition and Specialty applications.Ultra thin kerf with exclusive welded carbide teeth for fastest cutting speed and increased durability* — over 25% stronger tooth bond than traditional brazing methodsHeat resistant non-stick coating reduces binding and gumming for cleaner, truer cutsPerimeter venting allows faster chip ejection and a strengthened coreLaser cut plate with expansion control slots reduces warping and increases blade controlRing tensioned to maintain balance for straighter cuts*compared to IRWIN 24030**7-1/4” blades and largerSpecificationsItem #DescriptionTeethArborKerfHook AngleGrindApplications49352048-1/2" Miter/Table Saw Blade605/8" and Diamond Knockout2.4/2.3mm8°ATBTrim/Finish19343438-1/2" Miter/Table Saw Blade245/8" and Diamond Knockout1.6/1.5mm8°ATBTrim/Finish19343448-1/2" Miter/Table Saw Blade405/8" and Diamond Knockout1.6/1.5mm8°ATBTrim/Finish
