AG-Drill

Product catalog summary
Overview: The document provides detailed specifications and performance characteristics of the AG-ESS and AG-ES high-speed steel (HSS) drills, which are designed as alternatives to carbide drills. These drills are noted for their high alloy composition, offering enhanced chipping and wear resistance, even in larger sizes.
Specifications: The AG-ESS and AG-ES drills are available in various diameters, with detailed measurements provided for each size, including drill diameter (DC), cutting length (ℓ), overall length (L1), and shank diameter (Ds). The document includes comprehensive tables listing these specifications for both drill types.
Performance and Features: The new alloy HSS drills are designed for higher speeds and longer tool life, even in materials with hardness greater than HRC 32. They feature optimized groove geometry, shape relief, and helix angle, which contribute to superior chip formation and removal. The AG-ESS drills are particularly noted for their high-speed capabilities and reliability, comparable to carbide drills.
Tool Life and Efficiency: The document includes charts and data comparing the tool life of AG-ESS and AG-ES drills against competitors, highlighting their superior performance and longer tool life. The AG-ESS drills, for example, offer a 30% longer tool life than competitor coated HSS-PM drills.
Drilling Conditions: Standard drilling conditions are provided for various materials, including carbon steels, structural steels, alloy steels, mold steels, hardened steels, austenitic stainless steels, cast irons, ductile cast irons, aluminum alloys, and non-ferrous metals. The document advises on adjusting drilling conditions based on machine rigidity and work clamp state, and provides guidelines for using water-soluble and non-water-soluble cutting fluids.
Recommendations: The document suggests using collet chucks or milling chucks for optimal performance and advises on step feeding for deeper holes. It also provides notes on adjusting drilling conditions after regrinding.
Contact Information: The document lists contact details for NACHI EUROPE GmbH offices in Germany, the UK, Spain, and the Czech Republic, as well as factories and head offices in Japan.
