## Summary description

Adapter for trepanning (core/crown) drill bits by Evolution, model MK3 with a Weldon 19 mm connection. Designed to mount trepanning/coring bits on compatible MK3 spindles using the Weldon flat shank standard. Useful for metalworking and cutting core holes where a secure Weldon 19 mm drive and MK3 mounting interface are required.

## Long description

The Evolution MK3 Weldon 19 mm drill bit adapter is an arbor designed to mount trepanning (core/crown) drill bits on compatible MK3 spindles. It provides a Weldon 19 mm flat-shank connection to secure coring bits used in metalworking and other materials where a robust drive interface is required. The adapter is intended to interface between an MK3 spindle and trepanning cutters that accept a Weldon-style clamping surface, ensuring positive drive transfer and stable rotation during cutting operations.
Advantages
This adapter combines the MK3 mounting standard with a Weldon 19 mm flat-shank drive to deliver reliable torque transmission and reduced slippage for trepanning applications. Its construction is focused on accurate fitment and alignment to minimize runout and vibration during coring. The design allows quick installation on compatible spindles and secure retention of trepanning bits that use the Weldon flat, improving operational safety and cutting consistency.
Suitable for
Mounting trepanning/core/crown drill bits on MK3 spindles
Coring and creating large-diameter holes in metal
Applications requiring a Weldon 19 mm flat-shank drive for secure torque transfer
Workshop and industrial metalworking tasks that use trepanning cutters
Key specifications
Mounting interface: MK3 spindle compatibility

How to use
Fit the adapter into the MK3 spindle following the spindle manufacturer's instructions, ensuring correct seating and alignment. Insert the trepanning bit with the Weldon 19 mm flat positioned to engage the set screw or locking mechanism, then tighten the spindle and any retaining screws to secure the bit. Verify runout and make any necessary adjustments before starting the cutting operation. Use appropriate cutting speeds, feeds and coolant as recommended for the work material and trepanning bit.
Usage recommendations
Ensure the spindle and adapter are clean and free of debris before installation. Inspect the Weldon flat and locking screw for wear and replace worn components to maintain secure clamping. Match cutting parameters and use adequate coolant when coring metal to prolong tool life and improve hole quality.
