Milwaukee 4932479036 TCT Stainless Steel Holesaw 20mm
Milwaukee 4932479036 TCT Stainless Steel Holesaw 20mm
Product Description
The Milwaukee 4932479036 TCT Stainless Steel Holesaw 20mm is a professional-grade cutting accessory designed for fast, accurate drilling through stainless steel, mild steel, aluminium and other compatible materials. Featuring advanced tungsten carbide tipped (TCT) tooth technology, this durable 20mm holesaw delivers reliable cutting performance for electricians, plumbers, metal fabricators and maintenance professionals.
Engineered to provide up to 10 times longer service life than standard bi-metal holesaws, the Milwaukee 20mm TCT holesaw features robust carbide cutting teeth that can be resharpened to extend their working life. Its solid one-piece construction helps reduce wobble and vibration, allowing greater drilling accuracy when creating holes in sheet metal, pipes and other workpieces.
With an extra-deep 25mm maximum cutting depth, this stainless steel holesaw is suitable for demanding installation and fabrication applications. An integrated safety stop collar helps prevent over-drilling, while the built-in ejector spring assists with removing cut material slugs, reducing the risk of jamming and helping maintain productivity during repetitive drilling tasks.
The 10mm three-flat secure grip shank provides a firm connection inside the drill chuck, helping prevent slipping and supporting 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 4932479036 offers versatile performance for professional metalworking and installation tasks.
