Overview

This document details the AG Power series of high-speed steel (HSS) drills, designed for high-efficiency, fast-feed machining. It covers three main product lines—regular (AGPSD), semi-long (AGPSLSD), and long drills (AGPLSD)—each tailored for specific hole depths and machining needs.

Product Lines and Specifications

• AGPSD (Regular Size Drills): Suitable for hole depths up to 5×D, diameters 1.0–13.0 mm. Features high rigidity and a non-step flute design for efficient chip evacuation.
• AGPSLSD (Semi-long Drills): Designed for hole depths 5×D to 10×D, diameters 1.0–13.0 mm. Supports stable non-step drilling up to 7×D.
• AGPLSD (Long Drills): For deep holes up to 20×D, diameters 1.0–20.0 mm. Optimized for wear resistance and chip evacuation in deep hole drilling.

Key Features and Benefits

• AG Coating: Advanced cross-sectional coating enhances wear resistance, extending tool life significantly.
• Non-step Flute Design: Maintains drill rigidity while improving chip discharge, reducing cutting resistance and increasing machining stability.
• Cutting Performance: Lower thrust and torque compared to conventional drills enable faster feed rates and shorter machining times.
• Material Compatibility: Suitable for carbon steels, alloy steels, pre-hardened steels (25–40 HRC), some stainless steels, and titanium alloys. Not recommended for materials above 50 HRC or certain stainless steels (e.g., SUS304, SUS316).

Cutting Conditions and Machining Parameters

Recommended cutting speeds, spindle speeds, feed speeds, and feed per revolution vary by drill size and material. Examples include:

• AGPSD 3.0 mm: 30 m/min cutting speed, 3,180 rpm, 330 mm/min feed, 0.1 mm/rev feed.
• AGPSD 6.0 mm: 24 m/min, 1,272 rpm, 230 mm/min feed, 0.18 mm/rev.
• AGPSLSD 3.0 mm: 24 m/min, 2,500 rpm, 200 mm/min feed, 0.08 mm/rev.
• AGPLSD 6.0 mm: 18–30 m/min, 955–1,590 rpm, 143–160 mm/min feed, 0.1–0.15 mm/rev.

Performance Comparisons

AG Power drills outperform conventional drills in tool life, cutting force, and machining time. For instance, AGPSLSD drills achieve stable non-step drilling up to 7×D with tool life up to 500 holes versus about 12 holes for competitors. AGPLSD drills enable non-step drilling up to 20×D, reducing machining time by approximately 30% compared to step feed conventional drills.

Tool Life and Wear Resistance

Wear tests after hundreds of holes show minimal corner wear and optimized chip formation, contributing to longer tool life and consistent machining quality due to the AG coating and flute design.

Product Dimensions and Ordering Information

• Helix angle: 34°
• Point angle: 118°
• Diameter tolerance: h8
• Material: High alloy HSS with cobalt (Co)

Drill diameters range from approximately 1.0 mm to 20.0 mm depending on series, with detailed flute and overall lengths provided. Packaging is typically one drill per package; smaller diameters (<2.0 mm) come in sets of 10. Some products are exclusive to specific distributors in Japan.

Recommendations and Limitations

• Recommended for carbon steels, alloy steels, pre-hardened steels (up to 40–50 HRC), mold steels, cast irons, titanium alloys, and some nickel alloys.
• Not recommended for high hardness stainless steels (e.g., SUS304, SUS316) or materials above 50 HRC.
• Use water-soluble cutting fluids and vertical machining centers for optimal results.
• Reduce cutting speed and feed by 20% when using non-water-soluble fluids or machining rolled/forged surfaces.
• Employ step feeding for hole depths exceeding recommended limits, with intervals of 0.5–1×D (or 0.2–0.5×D for small diameters), returning the drill to the hole entrance between steps.
• Use collet or milling chucks for secure tool holding.
• Pre-drilling guide holes of 2–3×D depth are advised for long drills.

Operational Warnings

Adjust cutting conditions based on machine rigidity, workpiece clamping, and shape. Chip evacuation issues may require step feeding even for shallower holes. Proper coolant application and secure tool holding are critical to prevent tool damage and maintain machining quality.
