Optional Accessories - Hitachi CR 13VC Technical Data And Service Manual

The cutting speed of the Model CR 13VC is substantially higher than that of the current Model CR 12V, however,

the conventional HCS blades may be broken in heavy applications such as house demolition, etc. To cope with

this problem, the BI-METAL blades shown in Table 2 are provided. The BI-METAL blades are tough and rarely

break since they are made by electron-beam welding together of two different types of steels. A very hard steel

called "DM05" (JIS: SKH51 or equivalent molybdenum containing high speed tool steel) or "Matrix II" (JIS: SKH59

or equivalent cobalt containing high speed tool steel) is used at the cutting edges, and a flexible steel for spring

material is used for the blade main body. So these BI-METAL blades are remarkably stronger than the HCS

blades.

(1) HCS blades

The blade numbers of HCS blades in Table 1 are engraved in the vicinity of the mounting position of each blade.

Select appropriate blades by referring to Tables 1 and 3 below.
