Our Advantages

1. Advanced Manufacturing Equipment

• High-precision CNC grinding ensures perfect flute geometry and point angle accuracy for consistent drilling performance.
• High-temperature vacuum heat treatment optimizes hardness distribution, extending drill life under high-speed conditions.
• Ultra-precision polishing reduces friction during chip evacuation, minimizing heat buildup and workpiece damage.

2. Leading Smelting Process

• EAF + LF + VD + RS ESR technology produces steel with ultra-low impurities, enhancing drill toughness and resistance to chipping or breakage.

3. Cutting-Edge Heat Treatment

• Quenching + Cryogenic Treatment + Tempering achieves a balance of hardness (up to HRC 67) and flexibility, critical for drilling hardened materials without micro-cracks.

4. Unique RS ESR Technology

• Rapid Solidification ESR refines abrasive particle distribution in the drill's cutting edges, boosting wear resistance and thermal stability during deep-hole drilling.

5. Customizable Production

• Multiple HSS grades (e.g., M2, M35, M42) for different materials (stainless steel, titanium, etc.).
• Tailored flute lengths, helix angles, and coatings (TiN, TiAlN) to match specific machining needs.

 

Key Adaptations for Twist Drills:

• Emphasized flute precision and chip removal features.
• Highlighted point angle and helix angle customization for material-specific optimization.
• Added common HSS grades and coatings relevant to drilling applications.

 

FAQ

Q1: What materials and coatings are available for your straight-shank twist drills?

• Materials: High-speed steel (HSS/M2/M35), cobalt HSS (HSS-Co), powder metallurgy HSS (PM-HSS), etc...
• Coatings: TiN (general purpose), TiAlN (high-temperature resistance), TiCN (high hardness), with options for uncoated custom orders.
• Note: Coatings can extend tool life by 2- 3x, ideal for difficult-to-machine materials like stainless steel or titanium alloys.

 

Q2: What causes premature breakage or rapid wear during drilling?

• Operational issues: Excessive feed rate, insufficient cooling (use cutting fluid).
• Selection error: Hard materials require cobalt drills or coated variants.
• Policy: Technical support provided; replacements for non-human damage.

 

Q3: How to identify when a drill needs replacement?

• Signs: Increased burrs, abnormal cutting noise, hole diameter deviation >0.1mm.
• Tip: Regularly inspect edges under magnification for chipping.

 

Q4: How to choose the helix angle for twist drills?

• 30°-35° (standard): Suitable for steel and cast iron.
• 40°-45° (high helix): This is better for soft materials (e.g., aluminum and copper) to improve chip evacuation.
• Low helix (10°-20°): Recommended for hardened materials (e.g., quenched steel) to reduce vibration.

 

Q5: Can you customize non-standard drills (e.g., special edge geometry, internal coolant holes)?

• Custom options: Internal coolant holes (require drawings), step drills, multi-land designs.
