• Overall Length: 5 inches
• Sterile

The Zimmer Biomet 904301 3.2 mm twist drill bit is a precision surgical instrument crafted to create pilot or preparatory holes in bone structures as part of orthopedic or trauma procedures. With a 3.2 mm cutting diameter and a 5‑inch overall length, it strikes a balance between reach and rigidity, allowing the surgeon to access moderate depths of bone while maintaining control and stability. The twist flute design serves to remove bone debris (swarf) as drilling proceeds, reducing heat generation and improving cut efficiency.

Constructed to surgical standards, the bit is expected to exhibit tight tolerances in diameter, straightness, and flute geometry, ensuring smooth performance and consistency. In use, its robust construction helps resist flexing under load, which is especially important in delicate or constrained anatomical regions. The longer length gives it versatility for moderate depths, while still being manageable in terms of handpiece compatibility and handling.

In a surgical workflow, the 904301 bit is typically paired with a surgical drill motor or handpiece system. The surgeon advances the bit under controlled speed and torque to create a precise pilot channel. Because drill bits can dull or be damaged by excessive force or overheating, proper irrigation, speed control, and periodic cleaning of flutes are important to maintain sharpness and performance. Given its surgical grade and intended application, the 904301 drill bit is a critical consumable in many orthopedic and trauma instrument sets.
