47774 - Replacement Ultra-Glide(TM) Bearing Assembly (Includes #5009 1/8" hex key)

Since 1972, Amana Tool® has been producing router bits and has always used the highest quality materials. For example, Amana Tool® uses carbon alloy steel for its router bits that contains vanadium particles. This improves the structural integrity of the steel and prevents corrosion and defects in the internal structure of the material that can lead to cracks and breaks.

High-tech machinery processes the carbon alloy steel to manufacture the router bodies in a single clamping. This yields router bits with superior balance, centricity, precision and symmetry. 

The carbide used by Amana Tool® is supplied by CERATIZIT, the leading carbide producers in Europe. All of the company's carbide grades, many of which are exclusive to Amana Tool®, comprise sub-microscopic grain particles that create a finer edge for long-lasting performance, which is twice that of most standard carbide tools in the market, an asset when cutting solid surface. The carbide tips are then brazed onto the router bits using a fifty percent silver weld by machines also built especially for Amana Tool®.

Grinding is done with a sophisticated CNC machine in a single clamping, resulting in higher quality and precision in the finished tool. Delicate grain wheels are used to grind a cutting edge in the special harder grade carbide without creating microscopic cracks or breaks that could weaken the tool. All Amana Tool® products are then laser etched with essential information for the tool's use, such as RPM range and clamping depth. Laser etching ensures that this information cannot be erased through normal tool use.
