A reversible, indexable blade insert is removably secured to an anvil of a shear blade by one or more bolts through central bores in the blade insert. Each central bore includes recesses at each end which are adapted to receive a head of the bolt therein. A support member is provided within the recess of the blade insert central bore on the-inner side of the blade insert adjacent the anvil. The support member eliminates the unsupported section of the bolt in the recess, provides a positive blade insert location and increases the blade insert to anvil surface area friction.
