AG Starting Drills

Product catalog summary

Overview: The document provides detailed information about AG Starting Drills, highlighting their high positioning accuracy, versatility, and durability. These drills are designed for centering, chamfering, and V-groove cutting, maintaining precision even after extensive use.

Specifications: AG Starting Drills maintain a positioning accuracy within 0.02mm, even after drilling numerous holes. They are carbide-coated, making them suitable for various applications such as counter boring, deep guide hole drilling, and burr-less thin plate drilling.

Design Features: The drills feature a chisel-shaped tip for enhanced cutting edge strength and a large clearance angle for improved cutting performance. They are also available in a long shank series to minimize interference during deep hole drilling.

Applications: These drills are suitable for centering on curved surfaces, chamfering large diameter holes, and cutting V grooves. They are recommended for use with structural steels, carbon steels, alloy steels, mold steels, cast irons, stainless steels, aluminum alloys, and nonferrous alloys.

Drilling Conditions: The document provides standard drilling conditions for centering and chamfering, including recommended rotation speeds and feed rates for different materials. Adjustments are advised based on machine rigidity and workpiece conditions.

Product Range: The document lists various models of AG Starting Drills with different diameters, chamfer angles, and lengths, along with their respective prices.

Recommendations: It is advised to adjust cutting conditions based on the rigidity of the machine and workpiece. For non-water-soluble cutting fluids, reduce RPM and feed speeds by 20%. Use collet or milling chucks for optimal performance.
