  The shank, which is the part of the bit that fits into the rotary tool, is machined to the required diameter. It’s essential that the shank is perfectly round and smooth to ensure a secure fit and stable operation during use.

Heat Treatment

• Hardening:
  After machining, the bits undergo a heat treatment process to harden the material. This process involves heating the bits to a high temperature and then rapidly cooling them, a process known as quenching. Hardening increases the durability and wear resistance of the bit, ensuring it can withstand the stresses of high-speed cutting.

• Tempering:
  Following hardening, the bits are tempered to reduce brittleness. This involves reheating the bits to a lower temperature and then cooling them slowly. Tempering balances hardness with toughness, making the bits less likely to crack or chip during use.

Coating (If Applicable)

• Diamond Coating:
  For bits that require extreme hardness, such as those used for cutting glass or ceramics, a diamond coating may be applied. This process involves depositing a thin layer of diamond particles onto the surface of the bit, typically through a chemical vapor deposition (CVD) process. This coating significantly enhances the bit’s cutting performance and lifespan.

• Titanium Nitride Coating:
  Another common coating is titanium nitride (TiN), which provides a smooth, hard surface that reduces friction and heat buildup during cutting. This coating is particularly useful for bits that will be used on metals, as it helps to prevent the bit from overheating.

Finishing

• Grinding and Polishing:
  After heat treatment, the bits undergo a final grinding and polishing process to refine the cutting edges and remove any surface imperfections. This step is critical for ensuring the bit provides a smooth, clean cut and a high-quality finish on the workpiece.

• Balancing:
  Some rotary file bits, especially larger or longer ones, are balanced to ensure smooth operation at high speeds. This process involves removing small amounts of material from specific areas of the bit to ensure it rotates evenly without vibration.

Quality Control

• Dimensional Inspection:
  Each bit is inspected to ensure it meets the exact dimensional specifications required. This includes checking the diameter of the shank, the size and shape of the cutting head, and the overall length of the bit.

• Hardness Testing:
  The hardness of the bit is tested using a Rockwell hardness tester or similar equipment. This ensures the bit has been properly hardened and tempered, giving it the durability needed for industrial use.

• Cutting Performance Testing:
  Finally, a sample of each batch of bits is tested to verify its cutting performance. This involves using the bits on various materials to ensure they cut efficiently and produce the desired finish. Bits that do not meet performance standards are rejected.

Packaging

• Individual Packaging:
  Once the bits have passed all quality control checks, they are packaged individually to protect them during storage and transport. Packaging typically includes protective sleeves or cases that prevent the bits from being damaged or dulled before use.

• Bulk Packaging for Wholesalers:
  For wholesale orders, bits are often packaged in bulk, with multiple bits packed together in protective trays or boxes. This ensures that large quantities can be shipped efficiently while still providing adequate protection for each bit.
