The fein dura hss tin quickin holder mag drill hole cutter is engineered for tradespeople who demand efficiency, durability, and precision in metal drilling tasks. Designed with metric dimensions, this core drill bit integrates seamlessly with fein's quickin holder system, allowing for fast, tool free bit changes. Constructed from high speed steel hss and finished with a premium titanium nitride tin coating, the cutter delivers exceptional service life, outstanding glide properties, and enhanced heat resistance. The tin layer reduces friction and dissipates heat during cutting, resulting in smoother operation, longer tool life, and cleaner results – even on tough materials like stainless steel, mild steel, and structural steels. Whether you're carrying out core drilling in the workshop or on site, this hole cutter combines industrial grade strength with the ease and speed of quickin attachment.
