RUKO KEB-HSS-TiAlN-Ø48,0mm Hole Saw 48 mm Bi-Metal

Drilling large diameter holes in tough materials like stainless steel or metal pipes often leads to burnt-out saws and rough edges. The RUKO KEB-HSS-TiAlN-Ø48,0mm hole saw solves this with a bi-metal construction that combines a flexible body and a hardened HSS cutting edge with 8% cobalt for high heat and wear resistance. The 48 mm diameter and 38 mm cutting depth handle a wide range of tasks, from installing locks in doors to cutting openings in sheet metal, wood, plastics, plasterboard, and non-ferrous metals. The variable pitch tooth design reduces vibration and chatter, resulting in cleaner cuts and longer tool life.

Who is it for

This hole saw is ideal for professional tradespeople—electricians, plumbers, carpenters, and metalworkers—as well as serious DIYers who need reliable performance in demanding materials. It is especially suited for those who work with stainless steel or other tough alloys and require a tool that withstands high temperatures without losing its edge.

Main features

• Bi-metal construction: HSS cutting edge with 8% cobalt welded to a flexible alloy steel body.
• 48 mm diameter with 38 mm cutting depth for deep holes.

Tips

For best results, use a cutting fluid when drilling metal to reduce heat and prolong the saw's life. Ensure the arbor is securely tightened and the workpiece is clamped to prevent movement. Start at a low speed and increase gradually, especially when cutting stainless steel.
