Milwaukee 4932479058 TCT Stainless Steel Holesaw Set - 4 Piece

Product Description

The Milwaukee 4932479058 TCT Stainless Steel Holesaw Set is a professional 4-piece cutting kit designed for fast, precise drilling through stainless steel, mild steel, aluminium and other compatible materials. Featuring four tungsten carbide tipped (TCT) holesaws in 16mm, 20mm, 25mm and 32mm diameters, this versatile set provides essential cutting sizes for electricians, plumbers, metal fabricators and maintenance professionals.

Engineered for demanding metalworking applications, the Milwaukee TCT holesaw set uses advanced carbide tooth technology to deliver excellent cutting speed, durability and precision. The hard-wearing carbide teeth offer up to 10 times longer service life compared with standard bi-metal holesaws and can be resharpened to extend their working life. Each holesaw features a solid one-piece construction that helps minimise wobble and vibration, ensuring improved stability and accurate hole cutting.

With an extra-deep 25mm maximum cutting depth, these stainless steel holesaws are suitable for drilling sheet metal, pipes and other compatible materials. The integrated safety stop collar helps prevent over-drilling, while the built-in ejector spring assists with removing cut material slugs. These practical features help reduce jamming, minimise interruptions and improve productivity during repetitive drilling tasks.

Each holesaw features a 10mm three-flat secure grip shank, designed to prevent slipping inside the drill chuck and support effective torque transmission. The replaceable pilot drill and ejector spring allow convenient maintenance and extended usability. 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 4932479058 provides a reliable cutting solution for professional installation, fabrication and maintenance work.
