Frequently asked question (FAQ)

Question: What makes a micro drill with a long tip different from standard drills?
Answer: A micro drill with a long tip is specifically designed for small-diameter and deep-hole machining. Unlike standard drills, the long tip drill has a reinforced carbide body that provides stability at extremely small diameters (down to φ0.03 mm). Its optimized 120° tip angle and 30° helix help ensure precise chip evacuation, preventing tool breakage during deep drilling.
Question: Can the Micro Drill Long Tip be used on hardened materials?
Answer: Yes. This carbide drill is suitable for general steel, quenched and tempered steel, and stainless steel. However, when machining harder materials, it is essential to apply appropriate feed rates, speeds, and lubrication to avoid premature wear. For hardened steels above 50 HRC, specialized coated carbide drills may be more effective.
Question: How does the tolerance of +0 to -0.005 mm affect precision applications?
Answer: The extremely tight blade diameter tolerance (+0 to -0.005 mm) ensures that the micro drill consistently delivers high dimensional accuracy. This is critical in industries such as electronics, mold manufacturing, and fine mechanics, where even a few microns of variation can affect component performance and assembly.
Question: What are the best practices for using a long tip micro drill in deep hole drilling?
Answer: When using a long tip drill for deep hole machining, it is important to:
• Use peck drilling cycles to reduce chip accumulation.
• Maintain rigid fixturing to prevent deflection.
• Apply lubrication or air blast for chip evacuation.
• Keep cutting speeds moderate to balance tool life and hole quality.
Following these practices maximizes the efficiency and lifespan of the carbide drill.
Question: Why is the drill non-coated, and when would a coated version be recommended?
Answer: This micro drill long tip is non-coated to maintain sharp cutting edges for small-diameter precision drilling. Non-coated carbide drills are less prone to edge buildup when machining soft materials such as resins and aluminum. However, for abrasive materials or high-volume production, coated carbide drills (TiAlN, DLC, etc.) may offer extended tool life.
Question: In what applications is the Micro Drill Long Tip most commonly used?
Answer: The micro drill long tip is widely used in electronics, watchmaking, aerospace, and medical device manufacturing, where micron-level accuracy and deep hole drilling are required. Typical applications include fine holes in circuit boards, precision molds, microfluidic components, and small mechanical parts. Its carbide construction ensures durability even in continuous production environments.
