05H106 - Walter 1-3/8 Inch Carbide Tipped Annular Cutter with Universal Shank

Precision Drilling for Industrial Fabrication

The Walter 05H106 Carbide Core Cut Annular Cutter represents the pinnacle of drilling technology for heavy-duty industrial applications. Designed by Walter Surface Technologies, this 1-3/8" diameter cutter is engineered to tackle the most challenging materials found in modern fabrication shops, including stainless steel, cast iron, and high-tensile alloys. Unlike traditional High-Speed Steel (HSS) cutters that can dull rapidly when facing abrasive materials, this carbide-tipped tool maintains its cutting edge for significantly longer periods, ensuring consistent tolerance and finish quality across hundreds of holes.

One of the standout features of the 05H106 is its Universal Shank. This design consideration allows the cutter to be utilized with a wide array of magnetic drilling units without the need for specialized adapters, streamlining tool changes and reducing inventory requirements for diverse equipment fleets. The cutter features a 1-inch depth of cut, making it versatile for plate and structural steel applications commonly encountered in construction and manufacturing sectors.

Technically, the cutter employs a sophisticated flute and body design that optimizes chip evacuation. In deep hole drilling, chip removal is critical to preventing heat buildup and tool failure. The Walter Carbide Core Cut excels here, allowing for higher feed rates and rotational speeds. This efficiency translates directly to reduced cycle times and lower cost-per-hole, a crucial metric for high-volume production environments. Furthermore, the rigidity of the carbide inserts allows for precise engagement even on uneven or curved surfaces, reducing the risk of wandering or chatter that can compromise hole integrity.

For professionals demanding reliability and precision, the Walter 05H106 is an essential addition to the tool crib. It minimizes downtime associated with tool changes and sharpening, providing a robust solution for drilling large diameter holes in the toughest industrial metals.
