What is an Extra Long Length Drill Bit? How does it work?

Extra long length drill bits, sometimes called "aircraft extension drills" or "long series drills," are specialized tools designed for drilling deeper holes than standard drills can reach. Here's a breakdown of their characteristics and how they function:

Defining Features:

  • Extended Length: Significantly longer than standard twist drill bits, often ranging from 12 inches to 18 inches or more.
  • Reduced Shank: To accommodate the longer length, extra long drill bits often have a smaller diameter shank to reduce weight and improve compatibility with standard drill chucks.
  • Similar Core Design: The core design, with flutes and cutting edges, resembles a standard twist drill bit.

How Extra Long Drill Bits Work

The basic principle of operation is the same as any twist drill:

  1. Rotation: The drill bit is secured in a compatible drill press or other suitable machine and rotates at the appropriate speed.
  2. Cutting Action: Cutting edges at the drill bit's tip remove material as the drill bit penetrates the workpiece, creating a hole.
  3. Chip Evacuation: Flutes (spiral grooves) on the drill bit guide chips produced during drilling away from the cutting area and out of the drilled hole. Chip evacuation becomes more challenging with longer holes.

Why Choose an Extra Long Drill Bit?

Extra long drill bits are used when:

  • Deep Holes: You need to create holes that exceed the depth capabilities of standard drill bits.
  • Restricted Access: The drilling location is within a confined space or has obstructions, making a longer drill bit necessary.
  • Specialized Applications: Some industries, like aerospace or construction, might require extra long drill bits for specific tasks.

Considerations:

  • Rigidity: Extra long drill bits are inherently less rigid than shorter drills, increasing the risk of deflection or breakage. Careful drilling techniques and machine setup are crucial.
  • Chip Evacuation: Efficient chip removal is essential to prevent clogging and overheating in deep hole applications.

How are Extra Long Length Drill Bits manufactured?

The Journey of an Extra Long Length Drill Bit

The manufacturing process for extra long length drill bits involves several stages to achieve their extended length and the necessary precision. Here's a general overview of the typical steps:

Raw Material Selection:

Steel Matters: High-speed steel (HSS) or cobalt steel alloys are common choices for strength and wear resistance in deep drilling. Baucor can advise on the optimal material for your specific needs.

Blank Formation:

  • Elongated Form: The raw steel is cut and shaped to a much longer length than standard drill blanks, with a potentially smaller diameter shank section.

Flute Formation:

  • Specialized Grinding: Precision grinding processes create the spiral flutes essential for chip evacuation. Maintaining flute accuracy over the extended length is crucial. Baucor's grinding expertise would be invaluable here.

Cutting Edge and Point Creation:

  • Meticulous Grinding: The drill's tip and cutting edges are carefully ground to the desired point geometry. Consistency along the entire length is vital for accurate deep hole drilling.

Heat Treatment (If Applicable):

  • Enhancing Hardness: Some tool steel alloys undergo heat treatment processes to improve their hardness, wear resistance, and overall durability. Baucor's proficiency in heat treatment optimization could ensure maximum drill performance.

Coating (Optional):

  • Performance Boost: In some cases, extra long length drill bits might receive coatings like TiN, TiAlN, or others to further enhance wear resistance and reduce friction. Baucor's knowledge of drill coatings is a potential asset.

Quality Inspection:

  • Rigorous Examination: Straightness, flute consistency, and cutting edge sharpness are meticulously checked, as any imperfections are amplified in deep hole drilling.
  • Performance Testing: Testing on standardized materials might be employed to ensure consistent drilling performance over the bit's extended length.

What coatings improve Extra Long Length Drill Bits?

Applying specific coatings to extra long length drill bits can significantly improve their performance, reduce wear, and extend tool life. This is especially important in deep-hole drilling where chip evacuation and heat buildup are significant challenges. Here's a look at potential options you might find:

Standard Coatings:

  • Titanium Nitride (TiN): A highly versatile coating that increases surface hardness, reduces friction, and improves heat dissipation. TiN-coated extra long drills are likely a staple in Baucor's inventory, suitable for many applications.
  • Titanium Aluminum Nitride (TiAlN): An evolution of TiN coatings, offering even greater hardness and superior performance at elevated temperatures. Baucor might offer TiAlN coated extra long drills for demanding deep-hole drilling tasks.
  • Black Oxide: A less wear-resistant but common coating that offers some lubricity and corrosion protection. Might be found on less expensive extra long drills.

Specialized Coatings:

  • Chrome Nitride (CrN): Provides good wear resistance and performance in specific materials and applications.
  • Other Options: Zirconium Nitride (ZrN), Titanium Carbonitride (TiCN), and various multilayer coatings exist for specific performance enhancements. While rarer for extra long drills, Baucor has cutting-edge options available.

Factors Influencing Coating Choice

  • Compatibility: Certain coatings might be better suited to specific base materials (HSS, cobalt steel, etc.) or workpiece materials.
  • Application: The benefits of each coating can vary. Factors like increased wear resistance, reduced friction, improved heat dissipation, or chip evacuation influence the ideal coating choice based on the materials being drilled and the depth of the holes.
