With the Bahco 3830-98-VIP Sandflex hole saw, you cut clean, accurate 98 mm holes for piping, ventilation ducts, and electrical cabling with ease. Its bi-metal construction with 8% cobalt and variable 4/6 tpi tooth pitch minimises vibration while delivering outstanding wear resistance across wood, plastics, non-ferrous metals, and stainless steel. Featuring a maximum cutting depth of 38 mm, it powers smoothly through beams and sheet materials. When the cut is finished, the lateral knockout slots let you eject the core in seconds so you can keep moving without downtime. This threaded hole saw pairs easily with a compatible arbor on your drill.
