A BT40 sidelock holder is a precision tool holder designed for use with side milling cutters on CNC machines. It features a BT40 shank that fits into the machine spindle, providing a secure and accurate connection.

Key Features:

• BT40 Shank: Ensures precise alignment and rigidity in the machine spindle.
• Side Milling Cutter Interface: Designed to securely hold side milling cutters of various sizes and styles.
• Adjustable Depth of Cut: Allows for precise control over the depth of cut during machining operations.
• Coolant Through Hole (optional): Many sidelock holders have a coolant through hole to provide internal coolant delivery to the cutting tool, improving tool life and chip evacuation.
• Balancing: High-quality sidelock holders are balanced to minimize vibrations and ensure smooth operation at high speeds.

Applications of BT40 Sidelock Holders:

• Side Milling: Cutting along the side of a workpiece to create a groove or channel.
• Contour Milling: Creating complex shapes or contours on a workpiece.
• Pocketing: Milling out a pocket or cavity in a workpiece.
• Slot Milling: Cutting narrow slots or grooves into a workpiece.
