Annular Cutter Adaptor 31.75mm -19.05mm

Features

• 31.75 mm outer bore adapter provides the interface between larger-bore holders and the adapter.
• 19.05 mm (¾″) Weldon-shank compatibility accepts standard 19.05 mm Weldon-shank cutters for maximum flexibility.
• Precision-ground surfaces ensure true concentricity and secure seating of tooling.
• Hardened alloy steel construction delivers durability and resistance to wear in heavy drilling applications.
• Black protective finish offers corrosion resistance and improved workshop longevity.

Benefits

• Cost-effective tooling reuse: Use your existing 19.05 mm Weldon-shank cutter range in larger systems — no need to invest in separate tooling.
• Improved system flexibility: One owner can adapt between different machine interfaces quickly and easily on site.
• Maintained accuracy: Precision fit helps reduce vibration and improve finished hole quality, even in adapted setups.
• Versatile applications: Ideal for fabrication shops, on-site drilling, structural steel and plant maintenance where machine adapters vary.

Extra Information

• Before using the adaptor, ensure both the holder and adaptor faces are clean, undamaged and burr-free for accurate seating.
• Ensure the outer machine or tool holder bore of 31.75 mm is compatible and that the adaptor is fully secured before deploying the cutter.
• This adaptor is designed for use with 19.05 mm Weldon-shank cutters—using any other shank size may compromise safety or accuracy.
• Regularly inspect the Weldon flats, adaptor outer bore and mounting surfaces for wear or damage to maintain safe and accurate drilling.

Specifications

Safety

• Wear appropriate eye, ear and dust protection when operating magnetic base drills or annular cutter systems.
• Ensure the machine, magnetic base or holder is securely anchored and rated for the adapted setup before drilling.
• Check all mounting screws, Weldon flats and adaptor interface for tightness and no play before use.
• Do not use damaged or mismatched adaptors—it may lead to tool chatter, poor hole quality or machine damage.
