Milwaukee 4932479057 TCT Stainless Steel Holesaw 102mm
Product Description
The Milwaukee 4932479057 TCT Stainless Steel Holesaw 102mm is a professional-grade cutting tool designed to deliver precise, efficient drilling through stainless steel, mild steel, aluminium and other compatible materials. Equipped with high-performance tungsten carbide tipped (TCT) teeth, this heavy-duty 102mm holesaw provides excellent cutting speed, durability and accuracy for electricians, plumbers, metal fabricators and maintenance professionals.
Engineered for demanding metalworking applications, the Milwaukee 102mm TCT holesaw offers up to 10 times longer service life compared with standard bi-metal holesaws. Its hard-wearing carbide cutting teeth provide outstanding resistance to wear and can be resharpened to help maximise the working life of the tool. The solid one-piece construction helps reduce wobble and vibration, supporting greater drilling stability and accuracy when creating large-diameter openings in sheet metal, pipes and other suitable materials.
Featuring a maximum cutting depth of 25mm, this stainless steel holesaw is suitable for professional electrical installations, plumbing work, metal fabrication and general maintenance. The integrated safety stop collar helps prevent over-drilling, while the built-in ejector spring assists with removing cut material slugs. These features help minimise jamming, reduce interruptions and improve productivity during repetitive drilling operations.
The 13mm three-flat secure grip shank provides a reliable connection within the drill chuck, helping prevent slipping and ensuring effective torque transmission. Both the pilot drill and ejector spring are replaceable for convenient maintenance. Suitable for drilling steel with a tensile strength below 1200 N/mm² up to 4mm thick, stainless steel up to 2mm thick, aluminium, zinc, cast iron, copper, fibreglass and PVC, the Milwaukee 4932479057 delivers versatile cutting performance for professional metalworking and installation applications.
