Hole Saw Bosch PRO Multi Material PC Plus 44/64 mm — Single, 44–64 mm Diameter, for Drill, Drywall/Metal/Plastic/Softwood

Single-piece Bosch PRO Multi Material PC Plus hole saw, 44/64 mm diameter, designed for use with drills. This tool is intended to cut circular openings in drywall, metal, non-ferrous metals, plastic and softwood for common installation tasks such as electrical boxes, pipe penetrations and fixtures. The saw incorporates high-cobalt high-speed steel teeth and a Power Change system to simplify plug removal and arbor changes, providing a single 44–64 mm cutting solution for interior installation work.

Advantages

The construction uses HSS alloy with approximately 8% cobalt at the cutting edge to extend tool life and maintain cutting performance across multiple materials. An enhanced tooth geometry is designed to produce fast, smooth cuts in a range of substrates while reducing burrs. The Bosch Power Change compatibility allows quick removal of the cut plug and efficient changeover of hole saws and pilot bits, improving workflow on site.

Suitable for

• Cutting openings for electrical boxes in drywall and plasterboard
• Drilling holes for pipe penetrations in softwood and plastic
• Creating pass-throughs in thin sheet metal and non-ferrous metals
• On-site installation tasks where a single multi-material hole saw is preferred

Key specifications

• Diameter range: 44–64 mm
• Material of cutting teeth: High-speed steel (HSS) with cobalt alloy
• Compatible drive: for use with drills and Bosch Power Change keyless arbor systems
• Intended materials: drywall, metal, non-ferrous metals, plastic, softwood
• Design: single-piece hole saw with enhanced tooth geometry for multi-material cutting

How to use

Mark the centre of the required opening and secure the workpiece if possible. Fit the hole saw to a drill via a compatible arbor (Bosch Power Change keyless arbor if available) and set the drill to an appropriate speed for the material. Start drilling at low speed to establish the cut, then increase speed as recommended for the substrate while maintaining steady pressure. After cutting, stop the drill and remove the saw; use the Power Change feature or the arbor mechanism to eject the plug safely. Inspect the edge of the hole and deburr if necessary.

Recommendations

Use appropriate personal protective equipment such as eye protection and gloves, and secure loose workpieces. Match drill speed to material: lower speeds for metals, higher speeds for wood and plastics. Allow the saw to cool between extended cuts to preserve the cobalt-alloy teeth, and replace the arbor or pilot bit when worn to maintain accurate cutting.
