Application
Especially developed for use on pipe material and curved surfaces, for unalloyed and alloyed steels, non-ferrous metals, plastics and GFRP.
For material thicknesses up to 4 mm (3/16 inch); stainless steel up to 2 mm (1/16 inch).
Recommended for use on hand drills up to max. diameter 40 mm (1.9/16 inch) or stationary machines.

Execution

• The hole saw is manufactured from a single piece for diameters from 15.2 mm (3/16 inch) to 30.0 mm (1.1/8 inch)
• A special hardened holder is used for diameters from 31.0 mm (1.3/16 inch) to absorb torsional forces under heavy load and thus avoid premature shearing of the drive arbor
• Carbide-tipped
• Tapered centre drill bit with pre- and post-cutter, replaceable

Advantage

• High concentricity thanks to stable construction
• CAD-optimised chip angles with special grinding surface ensure high cutting performance and long service life
• Fast core removal by means of ejector spring
• Carbide tips allow repeated regrinding
• Repairable: Teeth can be replaced if they break

Delivery
1 hole saw
1 centre drill bit

Notes
When spot drilling pipes, drill with low contact pressure and avoid pendulum motions
For greater material thicknesses: Cut 2-3 mm (1/16-7/64 inch) in each work step, then remove the chips
A high-quality cutting oil should be used when sawing metals
Exceptions: Do not use cutting oil for cast iron and use petroleum instead of oil for aluminium
Note: Always wear safety goggles!
