Hole saw bi-metal 70mm

Hole saw diameter:
ø70mm
Use mandrel:
TC17007

Application:

The Bi-metal hole saw’s fast cutting power lies behind its HSS (hi-speed
steel) manufactured teeth.

The teeth have been set to a variable pitch to
improve harmonic vibration and to have a better chip clearance.

The hole saw can be used to cut into:

• Aluminium
• Copper
• Mild steel (sheet metal)
• Stainless steel (sheet metal)
• Zinc
• Wood
• Drywall (plaster board)
• PVC

The Bi-metal hole saws are primarily used by electricians, plumbers,
machinists and carpenters.

Features:

• Low vibration and even cut due to the variable pitched teeth.
• Strong electron beam welded cup design with a tough alloy body for added
  durability.
• Knock out hole for plug removal.
• Depth of cut: 38mm
• Long life – when used properly within the correct rpm and using a
  lubricant when cutting into metals.

Lubricant tip:
Use paraffin or beeswax when cutting into aluminium. Use
CT-90 or a general-purpose lubricating oil when cutting into steel.
