TDX Bi-Metal Holesaw 85mm – Durable & Accurate Large-Diameter Hole Cutting

Perfect for Builders, Electricians, Plumbers & DIY Hole Cutting Projects

The TDX Bi-Metal Holesaw 85mm is designed for users who need a dependable cutting accessory for creating consistent 85mm circular openings in suitable materials. Ideal for construction, electrical installations, plumbing work, renovations, maintenance, and workshop projects, its bi-metal construction provides a practical combination of cutting performance and durability for professional tradespeople and DIY users.

Description – TDX Bi-Metal Holesaw 85mm

The TDX Bi-Metal Holesaw 85mm is a practical power tool accessory designed for creating accurate 85mm circular openings with a compatible drill and holesaw arbor. Its purpose-built circular cutting design makes it particularly useful for projects where a larger opening is required and a conventional twist drill cannot conveniently provide the required diameter.

With an 85mm cutting diameter, this holesaw provides a clearly defined size for construction, installation, renovation, maintenance, and workshop requirements. It offers substantial cutting capacity for suitable fittings, services, fixtures, and other components requiring a larger circular opening.

The bi-metal construction is a key feature of the TDX holesaw. Designed to provide a practical balance between durability and cutting performance, it makes the holesaw suitable for regular professional and DIY applications when correctly matched to the intended material and drilling equipment.

A holesaw operates differently from a conventional drill bit. Instead of removing material throughout the entire diameter, the circular cutting edge works around the circumference of the opening.

This design provides an efficient method for creating larger holes because less material needs to be removed compared with drilling the entire area. It also helps users create a consistent circular opening corresponding to the specified holesaw diameter.

The 85mm size is particularly useful for users building a comprehensive collection of hole cutting accessories. It provides a larger option alongside smaller holesaws for projects where increased opening diameter is required.

For electricians, larger holes can be required for suitable fittings, components, cable pathways, and installation work. A dedicated 85mm holesaw provides a straightforward option when the required opening matches this diameter.

Builders and renovators can also use the TDX Bi-Metal Holesaw for suitable modifications during construction and property improvement projects.

Renovation work frequently involves adding new services or fixtures to existing structures. Having several holesaw diameters available makes it easier to select the correct cutting size according to the installation.

Plumbers and installers may also find the 85mm diameter useful for suitable service, fitting, and installation applications. The exact required opening should always be confirmed against the component before drilling begins.

Maintenance professionals can keep the holesaw available for repairs and modifications where larger circular openings need to be created.

For workshop users, the TDX 85mm Bi-Metal Holesaw can be incorporated into a broader drilling accessory collection alongside smaller hole saws, compatible arbors, and replacement pilot bits.

The holesaw requires an appropriate arbor to connect it securely to the drilling equipment. The recommended arbor for this 85mm holesaw is TDX 730892.

The arbor forms the connection between the holesaw and the drill and typically supports a pilot bit used to establish the centre point of the required opening.

The pilot drill engages with the workpiece before the larger circular cutting edge. This helps establish the intended location and guide the holesaw as cutting begins.

The recommended TDX 730892 arbor allows this 85mm holesaw to form part of a compatible modular hole cutting system. Users with several suitable holesaw diameters can select the appropriate cutting size according to the project.

For professional tradespeople, this modular approach can simplify tool organisation. Compatible hole saws, arbors, and pilot bits can be stored together in a toolbox, work vehicle, or workshop.

The 85mm diameter provides significant cutting capacity, so appropriate drilling technique is especially important. Larger holesaws have a greater cutting circumference and can place increased load on the drilling equipment.

Users should ensure the workpiece is securely supported and the drill is appropriate for the intended application.

The holesaw should be securely attached to the compatible arbor before use. The pilot bit and all connecting components should also be checked to ensure they are properly fitted.

Controlled pressure should be applied during drilling. Excessive force can reduce control and place unnecessary stress on the holesaw, arbor, drill, and workpiece.

Operating speed should be selected according to the holesaw diameter, material, and drilling equipment. Users should follow the relevant tool and accessory operating requirements.

For DIY users, the clearly specified 85mm diameter makes selection straightforward when a home improvement project requires a larger circular opening.

The holesaw should be inspected before each use. Damaged, worn, loose, or incorrectly fitted components should not be operated.

Appropriate personal protective equipment should also be used according to the power tool manufacturer's instructions and workplace requirements, particularly when drilling materials that generate chips, dust, or debris.

For New Zealand builders, electricians, plumbers, installers, maintenance professionals, workshop users, and DIY enthusiasts, the TDX Bi-Metal Holesaw 85mm provides a practical combination of large-diameter cutting capacity, durable bi-metal construction, and compatibility with an appropriate arbor system.
