Hole Saw Bosch PRO Multi Material 44/111 mm – single for drill, drywall, metal, non‑ferrous metal, plastic, softwood

Single Bosch PRO Multi Material hole saw model 44/111 mm designed for use with drills. This hole saw is intended for making clean circular openings for plumbing, electrical boxes, recessed lighting and ventilation. It works on drywall, steel cladding, non‑ferrous metals, plastic and softwood, offering a versatile solution for interior installation tasks.

Advantages

The saw uses high-speed steel with 8% cobalt in the teeth for improved durability and long life. An enhanced tooth profile provides fast, smooth cuts across multiple materials, while a new slot design simplifies plug removal. The Power Change plus system enables quicker exchange of hole saws and pilot bits.

Suitable for

• Installing electrical boxes and recessed lighting in drywall
• Cutting openings for plumbing pipes in interior walls
• Creating ventilation or duct openings in non‑ferrous metal and plastic
• Cutting clean holes in softwood for fixtures and conduits

When it may not be suitable

This hole saw is intended for interior installation materials and medium‑duty trades use. It is not designed for heavy demolition work or continuous cutting of thick hardened steel. For very hard ferrous steels or prolonged industrial use, a specialised bi-metal or carbide‑tipped solution may be more appropriate.

Key specifications

• Diameter: 111 mm
• Cutting depth: 44 mm
• Material of cutting edge: high‑speed steel (HSS) with 8% cobalt
• Applicable materials: drywall, steel cladding, non‑ferrous metals, plastic, softwood
• Connection system: compatible with drills using thread and Power Change plus for faster changes

How to use

Mount the hole saw on a compatible arbor or drill mandrel according to the drill manufacturer’s instructions and secure the pilot bit. Mark the centre of the desired opening, position the pilot bit, and start drilling at low speed to establish the hole. Increase speed as needed and apply steady moderate pressure. Use the slot in the saw to pry out the cutting plug when the hole is complete. Follow all safety guidelines for drill use and wear eye and hand protection.

What to consider before purchase

• Check that the 111 mm diameter and 44 mm cutting depth meet your installation requirements
• Ensure compatibility with your drill’s arbor thread and Power Change plus system or obtain a matching mandrel
• Consider material types you plan to cut — this saw is optimised for drywall, non‑ferrous metals, plastic and softwood, and light steel cladding

Usage recommendations

Use moderate, consistent pressure and appropriate drill speeds for each material. Clear the cutting plug via the saw’s slot frequently during extended cuts to maintain performance. For cutting metal, use cutting fluid if recommended for the workpiece to extend tool life.
