05Z036 - Walter Pilot Pin for 4-Inch Depth of Cut Annular Cutters

Precision Centering and Ejection for Deep Hole Drilling

The Walter 05Z036 Pilot Pin is a critical accessory designed for heavy-duty magnetic drilling operations. Engineered specifically for use with annular cutters featuring a 4-inch depth of cut (DOC) and a 1-1/4 inch Weldon shank, this pin ensures your drilling setup operates with maximum efficiency and safety. When tackling deep holes in structural steel or heavy plate, the reliability of your guide pin is just as important as the sharpness of your cutter.

Robust Construction for Industrial Use

Walter Surface Technologies is known for producing high-performance industrial tools, and this pilot pin is no exception. It is crafted from hardened and precision-ground steel. This high-quality construction minimizes the risk of the pin bending under the stress of operation, which is a common issue with inferior pins. A straight, durable pin is essential for accurate hole placement, as it serves as the primary guide before the cutter teeth engage the material.

Three Critical Functions

This pilot pin performs three vital roles during the drilling process:

• Positioning: The sharp tip allows the operator to precisely align the magnetic drill over the center punch mark, ensuring the hole is drilled exactly where intended.
• Coolant Control: In many magnetic drill systems, the pilot pin acts as a valve. As the pin retracts into the arbor during the cut, it opens the internal coolant flow, delivering lubrication directly to the cutting teeth where it is needed most.
• Slug Ejection: Upon completion of the cut, the spring-loaded mechanism behind the pin forcefully ejects the solid metal slug from the center of the cutter. This prevents the slug from jamming inside the tool, allowing for immediate setup of the next hole.

Compatibility

The 05Z036 is designed to fit the larger range of Walter annular cutters, specifically those requiring a longer pin due to a 4-inch cutting depth. It is compatible with Walter's SST Core Cut, ICECUT, and Carbide series cutters that utilize the 1-1/4" Weldon shank standard. Ensure your cutter matches these specifications to guarantee proper fit and function.
