## Long description

GRAPHITE adapter 55H320 converts a tool arbor with M14 thread to a HEX (hexagonal) shank, enabling the use of hole saws and similar accessories with drills or impact drivers that accept HEX bits. The adapter is intended to transfer torque from the power tool to the hole saw reliably, providing quick fitting and removal and expanding compatibility between M14-threaded accessories and hex-chuck tools.
Advantages
The adapter provides a secure mechanical connection between M14-threaded arbors and tools with a six-sided HEX chuck, improving torque transmission and reducing slippage during cutting. Its compact design allows fast installation and release of hole saws without the need for additional adapters. Manufactured to fit standard M14 arbors and HEX-driven tools, it simplifies tool changes and increases the number of compatible power tools for hole-saw applications.
Suitable for
Installing and removing hole saws on drills and drivers with HEX chucks
Cutting circular openings in wood, plastic and thin metal sheets when using appropriate hole saws
Working on construction, electrical and plumbing installations that require circular holes
Using impact drivers or cordless drills with 1/4" HEX bit holders
Key specifications
Connection type: M14 threaded female to 6-sided HEX shank
Shank form: hexagonal shank for quick-fit hex chucks
Material: hardened steel construction for torque transfer and durability
Compatibility: designed for standard M14 hole saw arbors and HEX-bit accepting tools
Finish: corrosion-resistant surface treatment for extended service life
How to use
Thread the adapter onto the M14 arbor of the hole saw until it is securely seated, then insert the HEX shank into the drill or driver chuck designed for hex bits. Ensure the connection is properly engaged before starting the tool. Operate the power tool at speeds and feed rates appropriate for the hole saw and the work material, applying steady pressure and allowing the cutter to do the work. After use, stop the tool, withdraw the adapter from the chuck, and unfasten it from the arbor if required.
Usage recommendations
Use the adapter only with hole saws and power tools rated for the intended materials and cutting speeds. Match the hole saw type and size to the workpiece and check that the drill or driver can supply sufficient torque. Wear appropriate personal protective equipment, secure the workpiece, and follow the hole saw manufacturer's instructions for pilot bits and cutting technique to avoid binding or overheating.
