Hole Saw Bosch PRO Multi Material 44/16 mm is a single hole saw for use with a drill, designed to cut precise circular openings in drywall, metal (including non-ferrous metals), plastic and softwood. Supplied as one piece, it is intended for tasks such as installing pipes, conduits, fixtures and other recessed fittings during construction, renovation, electrical and plumbing work.

Advantages

An enhanced tooth geometry provides faster, smoother cuts across a range of materials, while a new slot design simplifies removal of material plugs. The product supports a cutting depth of 44 mm and is compatible with hole saws that use a threaded connection.

How to use

Fit the hole saw onto a compatible arbor and secure it to your drill. Mark the center point of the intended cut and use a suitable pilot bit if available. Start drilling at low speed to establish the cut, then increase speed as appropriate for the material. Periodically withdraw the saw to clear swarf; use the slot design to remove the material plug safely once the cut is complete. Follow drill and hole saw manufacturer safety instructions and wear appropriate protective equipment.

What to consider before purchase

• Compatibility with your drill arbor and threaded hole saw mount
• Type of material to be cut (ensure suitability for drywall, non-ferrous metals, plastics or softwood)

Usage recommendations

Use steady pressure and appropriate drill speed for the material. For metal, apply cutting lubricant as needed. Clear chips frequently and replace the hole saw if teeth become worn to maintain cutting quality.
