Bosch 2 x 14" sds-max scaling chisel Reference Guide

Color-Coded System

Bosch uses only superior virgin 

grains made to exact specifications. 

The chemical structure of the 

grains determines the physical 

properties (e.g. shape, sharpness, 

hardness, friability).

 Aluminum  Oxide: A tough, block-

shaped grain used for cutting metals 

and other high-tensile strength 

materials without excessive fracturing.
 Silicon Carbide: A hard, sharp 

abrasive suited for non-metallic 

materials such as concrete.

 Aluminum  Zirconium: A fine, 

dense crystalline grain that can be 

used for rugged stock removal.
