Adapter for Hole Saws högert technik HT6D463 is a hex-shank arbor with a 7/16" drive designed to secure and drive circular hole saws sized 32–152 mm. The adapter converts a compatible drill or quick-change chuck to accept hole saws with a 7/16" arbor interface, enabling controlled rotary cutting in materials such as wood, plastic and gypsum board when used with the correct hole saw cutters.

Advantages

The hex 7/16" arbor provides a secure positive drive and reduced slippage compared with smooth-shank adapters. Its construction ensures stable concentric rotation for cleaner holes and longer cutting tool life. The adapter is compact and simple to install, enabling quick changes between hole saws in the 32–152 mm range and compatibility with drills and systems that accept hex shanks.

• Cutting circular openings in wood for plumbing, electrical and carpentry work
• Making holes in plastic panels and housings
• Cutting openings in gypsum board for fixtures and outlets
• General-purpose hole saw applications where a 7/16" arbor connection is required

Key specifications

• Arbor type: hex shank
• Drive size: 7/16" (7/16 inch)
• Compatible hole saw diameter range: 32–152 mm
• Intended materials: wood, plastic, gypsum board and similar soft construction materials when paired with appropriate hole saws
• Mounting: designed for use with drills or quick-change chucks that accept hex shanks

How to use

Select a hole saw within the 32–152 mm range that matches the material and required hole diameter. Secure the pilot bit and hole saw onto the adapter following the hole saw manufacturer's instructions, then insert the hex shank into the drill or quick-change chuck until fully seated. Start drilling at low speed to establish the pilot hole, then increase speed as appropriate while maintaining steady pressure and alignment to ensure an accurate, clean cut.

Usage recommendations

Use appropriate safety equipment such as eye protection and dust extraction when cutting. Match the hole saw tooth type and pilot bit to the work material, avoid excessive feed pressure to prevent binding, and reduce speed for larger diameters near 152 mm. Regularly check the adapter and hole saw for wear and secure fastening before each use.
