Drill Holder

Drill holders are a type of tool holder used in metalworking machinery, specifically in machine tools. They are part of the supply class Machine Tool Accessories in the supply group Metalworking Machinery.

Drill holders are designed to securely hold drill bits in place during drilling operations. They provide stability and precision, ensuring accurate drilling and reducing the risk of tool slippage or breakage. Drill holders come in various types and sizes to accommodate different drill bit diameters and shank styles.

Some common types of drill holders include:

1. Drill chucks: These are the most common type of drill holders. They consist of a three-jawed chuck that can be tightened or loosened to hold the drill bit securely. Drill chucks are typically used in handheld drills or drill presses.

2. Collets: Collets are cylindrical holders that grip the drill bit by compressing around its shank. They provide a more precise and concentric grip compared to drill chucks. Collets are commonly used in CNC machines and high-precision drilling operations.

3. Quick-change drill holders: These holders allow for rapid tool changes without the need for manual tightening or loosening. They often use a locking mechanism or a quick-release system to secure the drill bit in place.

Drill holders are essential accessories in metalworking machinery as they ensure the proper alignment and stability of drill bits, resulting in accurate and efficient drilling operations.
