Hole Saw Bosch Bi‑Metal Single for Drill, Ø 2.4 cm, for Drywall/Metal/Plastic/Softwood, 1 pc

Bosch Bi‑Metal Single Hole Saw for Drill, Ø 2.4 cm, is a single-piece cutting tool designed for creating precise circular openings in drywall, metal, non‑ferrous metal, plastic and softwood. Constructed from bi‑metal HSS with enhanced cobalt content, the hole saw combines flexibility and wear resistance to support repeated cutting tasks in mixed-material applications. Supplied as one unit, it is intended for use with standard hole saw arbors and drills with compatible thread and a cutting depth up to 44 mm.

Advantages

The bi‑metal construction with high-speed steel and cobalt alloy delivers improved durability and maintains cutting performance across a range of materials. A Vario tooth strip tooth configuration helps the saw start and glide through workpieces, reducing the need for excessive feed force and producing smoother edges. The tool’s compatibility with common arbors and drill attachments ensures straightforward integration into existing tool sets without specialized adapters.

Suitable for

• Making circular openings for pipes and conduit in drywall and plasterboard
• Cutting holes in thin sheet metal and non‑ferrous metal panels
• Creating access or passthrough holes in plastics and composite panels
• Drilling service and routing holes in softwood and timber for installations

How to use

Mount the hole saw onto a compatible arbor following the arbor manufacturer’s instructions and secure it to the drill. Mark the centre point of the intended opening and start drilling at a moderate speed to establish the pilot position. Apply steady, even pressure while keeping the drill aligned perpendicular to the work surface; reduce speed when cutting metal to avoid overheating. After cutting, remove the plug and deburr the hole if necessary to achieve a clean finish.

Usage recommendations

Use personal protective equipment such as safety glasses and gloves. For metal and non‑ferrous work, apply cutting lubricant to extend tool life and reduce heat. Avoid excessive side loads and ensure the drill’s RPM is appropriate for the material: lower speeds for metal, medium speeds for plastics and softwood, and higher speeds for drywall.
