Annular Cutter Adaptor 19.05mm -31.75mm

Features

• Inner interface 19.05mm (¾″) Weldon-shank compatible accepts standard 19.05mm cutters.
• Outer interface 31.75mm bore fits into larger holder systems allowing cross-compatibility.
• Precision-machined surfaces ensure proper alignment and minimal run-out of the cutter.
• Hardened alloy steel construction for toughness under drilling load and vibration.
• Black protective finish aids durability and resistance to workshop conditions.

Benefits

• Tool reuse: Use your 19.05mm Weldon-shank cutters on larger machine holders, avoiding new investments.
• Better machine flexibility: Easily adapt tooling between machines with different bore sizes or setups.
• Maintained precision: Ensures accurate drilling even when adapting between different interface sizes.
• Applicable across sectors: Useful for fabrication, site construction, structural steel drilling and workshop retrofits.

Extra Information

• Before mounting, check both adaptor and holder faces are clean, burr-free and properly secured to maintain accuracy.
• Confirm the outer holder bore size is 31.75mm and the cutter shank is 19.05mm Weldon to guarantee compatibility.
• When adapting sizes, reduce feed speed slightly and monitor vibration as the assembly may have different stiffness characteristics.
• Inspect the adaptor and cutter interface frequently for wear, especially if frequently swapping between sizes.

Specifications

Safety

• Wear appropriate eye, ear and dust protection when operating drilling systems with adaptors and annular cutters.
• Ensure the machine, magnetic base or holder is securely anchored and rated for the adapted setup before commencement.
• Check that all mounting screws, shank connections and interfaces are tight with no play before use.
• Do not use worn or damaged adaptors or cutters as this may cause chatter, mis-drilling or machine damage.
