Product Overview

The WeldTec™ platform combines various attributes to deliver long lasting cutting performance. A revolutionary tooth geometry and an updated tooth set enables faster and smoother cuts, as well as improved longevity. IRWIN® Bi-Metal Hole Saws cut through a variety of materials, including: Aluminum, Copper, Iron, Stainless Steel, Wood and Zinc. The electron beam welded High Speed Steel (HSS) cutting edge ensures stronger, longer lasting teeth. Precision set teeth provide faster penetration and cutting. And, the bi-metal construction delivers toughness and long life.

Additional Features

  • TIN COATING: has a hardness of app. 80 HRC and is very resistant to wear
  • MORE EFFICIENT: TiN has a low coefficient of friction. This results in less power being consumed and less heat generated during the drilling
  • SPEED AND FEED: Compared to traditional HSS Twist Drill Bits,, speed can be increased by 40-60% and feed by 10-20%
  • LESS HEAT: Tin is also a poor conductor of heat, so the heat generated during the drilling process is diverted into the chips and coolant and less into the drill bit
