Metal Hole Saw
- Regular pitch.
- BiM-Co (Bi-metal with 8%Co), teeth milled, side set.
- Variable tooth splitting for less vibration.
- Excellent cutting results in (alloyed) steel and stainless steel due to 8% cobalt alloy base material.
- Less heat production.
- Robust design with extra firm lid for more stability.
- High precision of concentric running.
- Smoother cutting.
- Cutting depth up to 38 mm.
- Used by an adapter for bi-metal hole saws with hexagonal shank Ø 1/4 “[5/8” x 18 UNF] [10 mm].
- For sawing holes in most commonly used metals, plastics and woods.
- Material groups: 1.1-1.5 / 1.6 / 2.1 – 2.2 / 2.3 / 3.1 – 3.3 / 4.1 – 4.12
- RPM 1: recommended speed for Wrought Steel.
- RPM 2: recommended speed for Cast Iron.
- RPM 3: recommended speed for Stainless Steel.
- RPM 4: recommended speed for Copper Brass.
- RPM 5: recommended speed for Aluminum.
