For the removal of damaged screws, stud & bolts. Left hand drill bits remove fasteners or creates the pilot hole required for a screw extractor. If the LEFT HAND DRILL does not remove the fastener, the hole drilled becomes the preparation for a screw extractor. The opposite direction flute enables the broken fastener to be gripped and wound out of the hole. The opposite direction flute permits reverse drilling, which stops the fastener being driven tighter. Ensure drill is run in reverse

This high-precision modular tapping chuck set is the ideal solution for producing accurate, high-quality threads in a variety of machining environments. Designed for efficiency and tool protection, the system features a built-in adjustable torque limiter to prevent tap breakage and a floating holder to correct any misalignment between the spindle and the pre-drilled hole.The modular design allows for rapid tool changes, utilizing quick-change collets that eliminate the need to remove the chuck from the machine spindle when changing tap sizes.
Key Features:
Quick-Change Collet System: Includes a complete set of 7 precision collets for fast and secure tap changes, maximizing machine uptime.
Adjustable Torque Limiter: Protects expensive taps from overload and breakage caused by dull taps, chips, or bottoming out in blind holes. The torque can be easily adjusted to suit the material and tap size.
Versatile Threading: Suitable for both right-hand and left-hand threading operations.
Compensating Floating Holder: The chuck design allows for radial float and axial compensation, ensuring perfect thread concentricity and extending tap life.
Multi-Machine Compatibility: Robustly constructed for use in CNC mills, manual milling machines, drill presses, lathes, and boring machines.
