Abstract
A saw blade for producing a trapezoidal shaped groove in a surface including a circular support disc and a plurality of spaced-apart abrasive elements supported about the periphery of the support disc wherein the abrasive elements include a first set of a generally rectangular cross sectional configuration and a second set of a generally trapezoidal cross sectional configuration wherein the use of the two sets of abrasive elements extends the wear life of the saw blade.
Claims13
A saw blade for producing a trapezoidal-shaped groove in a surface comprising:
- a circular support disc and a plurality of spaced-apart abrasive elements supported about the periphery of said support disc, said abrasive elements including a first set of a generally rectangular cross sectional configuration having a flat, work-engaging end surface of a predetermined width and a second set of a generally trapezoidal cross sectional configuration having a work-engaging end surface and sloping work-engaging side surfaces defining a maximum width greater than the width of said first set of abrasive elements.
A saw blade for producing a trapezoidal-shaped groove in a surface comprising:
- a circular support disc and a plurality of spaced-apart abrasive elements supported about the periphery of the support disc, said abrasive elements including a first set of a generally rectangular cross sectional configuration having a flat, work-engaging end surface of a predetermined width (w.sub.1) and a second set of generally regular trapezoidal cross sectional configuration having a base of predetermined width (w.sub.2), a work-engaging end surface of a predetermined width (w.sub.3) which is smaller than the base width (w.sub.2) and approximately equal to the width (w.sub.1) of the work-engaging end surface of the rectangular abrasive elements.
