Hole saw Bosch 2 608 594 229, single piece, Ø 70 mm, for drill, for aluminium/metal/plastic/drywall

Single hole saw Bosch 2 608 594 229, Ø 70 mm, designed for use with a drill to create precise circular openings in a variety of installation and building materials. The BiM Progressor construction combines high‑performance bi‑metal with 8% cobalt alloy and an enhanced progressive tooth strip to deliver faster cutting and extended service life compared with previous designs. Supplied as one piece in a blister pack, this hole saw is intended for use on aluminium, non‑ferrous metals, metal, pipe, drywall, plasterboard, plastic and PVC when paired with appropriate arbors and drill drivers.

Advantages

The BiM Progressor design provides up to twice the lifetime of the predecessor through a bi‑metal tooth strip with 8% cobalt that improves wear resistance during prolonged cutting tasks. The progressive tooth geometry ensures efficient chip evacuation and faster penetration into the workpiece, reducing cutting time. Compatibility with both corded and cordless drills and suitability for a wide range of materials make the saw versatile for on‑site and workshop use. The single‑piece blister pack offers simple storage and transport.

Suitable for

• Cutting circular openings in aluminium panels and sheets
• Drilling through non‑ferrous metals and thin steel
• Creating holes in drywall and plasterboard for electrical boxes and fixtures
• Making openings in plastic and PVC for pipe penetrations and fittings
• General installation and maintenance tasks requiring 70 mm diameter holes

• Intended tool: compatible with corded and cordless drill drivers (use with appropriate arbor)
• Suitable materials: aluminium, non‑ferrous metal, metal, pipe, drywall, plasterboard, plastic, PVC
• Packaging: single piece in blister pack

How to use

Install the hole saw on a compatible arbor and secure it to the drill driver according to the arbor manufacturer’s instructions. Mark the centre of the desired opening and, when appropriate, use a centre drill or pilot bit to start accurately. Begin drilling at low speed to establish the cut, then increase speed moderately while applying steady, even pressure. Periodically retract the saw to clear chips and prevent overheating when cutting metals or dense plastics. After completing the hole, remove burrs or sharp edges with a file or deburring tool as required.

Usage recommendations

Use cutting lubricant when drilling non‑ferrous metals or steel to extend tool life and improve finish. For thicker or harder metals, reduce feed pressure and operate at lower speeds. Ensure the arbor and pilot bit are rated for the hole saw and check that the drill’s torque and speed settings are appropriate for the work material. Wear suitable personal protective equipment including eye protection, gloves and hearing protection.
