II. Material Description
- Premium Material & Craftsmanship: Stanbal Coffee Drills are entirely crafted from high-quality industrial-grade M2 High-Speed Steel (HSS), without surface titanium coating, displaying the original M2 HSS color and superior toughness.
- Advanced Hardness & Heat Resistance: High-speed steel inherently provides exceptional cutting performance and toughness. Following strict precision heat treatment, it delivers outstanding durability and wear resistance, maintaining stable cutting capabilities even during continuous drilling operations.
- International Standards: Manufactured with precision in strict compliance with DIN international dimension standards, ensuring high precision and consistent cutting stability with every operation.
- Designed for Tough Materials: Specially developed for high-intensity construction and hard-to-cut materials, featuring fast cutting speeds and tight tolerances to effectively reduce cutting resistance and significantly boost work efficiency.
III. Product Features
- Wide Application: Extensively suitable for drilling and precision machining on various metals (such as stainless steel, iron sheets, aluminum), wood, and plastics.
- High-Efficiency Cutting: Specially tailored for difficult-to-cut materials, delivering fast cutting speeds and minimal tolerances to enhance productivity.
- Professional Endorsement: Backed by over 30 years of market experience, highly praised by professional hardware stores and tool shops.
- Field Test Verification: Please search for "STANBAL" on YouTube to watch actual operation demonstrations.
IV. Usage & Maintenance Guide
【Correct Usage】
- Material Compatibility: This product is suitable for stainless steel (304/316), high-carbon steel, mold steel, titanium alloys, cast iron, as well as alloy steel, aluminum alloys, wood, and plastics. When drilling high-hardness materials (such as stainless steel), always apply water or cutting fluid adequately for cooling to extend tool life.
- Machine Matching: Designed with a standard 6.35mm hex shank, suitable for various quick-change chucks and impact drills, enabling fast and convenient assembly/disassembly.
- Speed Control: The larger the drilling diameter, the slower the drill speed should be set. High-speed blind drilling is strictly prohibited to prevent drill bit overheating and damage. When drilling stainless steel, always use the proper technique of "low speed, heavy pressure".
【Routine Maintenance】
- Cleaning & Protection: After use, clear residual chips and debris from the flutes, wipe off oil, sweat, or cutting fluid with a clean cloth, and store in a dry environment.
- Regular Oiling: If left unused for an extended period, apply a thin layer of anti-rust oil or lubricating oil on the metal surface to maintain performance.
- Storage Management: After using individual bits, store them properly in a moisture-proof tool box or dedicated drill rack to prevent cutting edge damage from collisions.
