Busch Abrasives - Ordering Information and Recommendations

"Best Quality for Best Results"

Ceramically bonded rotary abrasives were used for the first time in the late La Tene period (approx. 150 - 0 BC), a development which was probably triggered by the use of potters' wheels.

Around 1500 AD, Leonardo Da Vinci produced designs for grinding machines.

As the result of the widespread use of dental engines, Busch has been supplying abrasives for dental purposes since the start of the 20th century.

Silicon carbide (SiC) and high grade corundum are primarily used today as a basic material for abrasives. These materials, provided in different grits, are bonded with ceramic materials, magnesite, or synthetic resin in different hardnesses; the type and hardness of the bond determines the wear behavior. Optimum combination in conjunction with highly-precise manufacture results in the right product for different applications.

The Busch product range is tailored to meet certain requirements: silicon carbide and high grade corundum abrasives, including the new ALOX abrasives with ceramic bond, HITZLOS ("heatless") and SILENT abrasive wheels with magnesite bond.

Busch abrasives make processing of numerous materials extremely economical.

Specify color, type, and number when ordering. All items available in straight Handpiece only, unless otherwise indicated.

Material: Only high quality raw material specially selected is used. Shanks are made of nickel plated tool steel or stainless steel.
