Hole saw, Wolfcraft Bi-metal single, Ø 2.9 cm, for drill, suitable for drywall, metal, plastic, plywood, steel, wood

Wolfcraft Bi-metal single hole saw, Ø 2.9 cm, is a compact cutting tool designed for use with handheld drills to create clean circular openings. Constructed from bi-metal material with a specially alloyed body and HSS teeth, this single-piece hole saw is supplied with a 6 mm HSS centring drill and is immediately ready for use without a separate mandrel. It is suitable for cutting a range of materials including drywall (gypsum plaster boards), plastic, plywood, non-ferrous metals, steel and wood, making it a versatile option for installation and repair work where small-diameter holes are required.

Advantages

The bi-metal construction combines flexibility and wear resistance to extend tool life while HSS teeth provide efficient cutting performance across different materials. Supplied as a single piece with an integrated centring drill, the hole saw is ready for direct attachment to a drill, eliminating the need for additional mandrels or adapters. Its compact 2.9 cm diameter allows precise openings for cables, pipes and fixtures with minimal chipping in delicate substrates like drywall and plywood.

Suitable for

• Creating circular openings for small pipes and conduits
• Routing cable and conduit entries during installation
• Making passthroughs for fixtures and fittings in cabinets and furniture
• Repair work and on-site modifications in drywall, wood and metal

How to use

Fit the hole saw directly to a compatible drill according to the drill manufacturer’s instructions. Ensure the included 6 mm HSS centring drill is correctly seated to guide the saw during the initial penetration. Start drilling at low speed to establish the centre hole, then increase speed gradually while maintaining steady pressure. Keep the drill perpendicular to the work surface for a clean, round cut. Withdraw the saw periodically to clear chips and prevent overheating when cutting metal or dense wood.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. For metal cutting, apply cutting lubricant to reduce heat and extend tool life. Secure the workpiece and avoid excessive feed pressure; allow the saw to cut at its intended pace. After use, clean the tool of debris and store it in its box to protect the HSS teeth.
