Hole saw AWTools OTWORNICA BIMETALOWA 16 mm - AWTools AW49518

AWTools OTWORNICA BIMETALOWA 16 mm is a 16 mm bimetal hole saw designed for cutting round holes in metal and other materials where bimetal blades are suitable. The compact diameter provides precise, clean cuts for installations and workshop tasks. The hole saw fits standard arbors and is compatible with handheld drills and drill presses that accept its mounting system, making it a practical choice for electricians, plumbers and general maintenance work.

Advantages

The bimetal construction combines high-speed steel cutting edges with a flexible backing, offering improved wear resistance and durability compared with simple high-carbon steels. The 16 mm cutting diameter allows for compact holes required in many installation tasks, while the tooth geometry is optimized to cut through thin sheet metal, pipes and similar materials with reduced risk of snagging. Suitable for use with both portable drills and drill presses, the tool delivers repeatable hole quality and a relatively long service life under normal operating conditions.

Suitable for

• Cutting round holes in thin sheet metal and metal pipes
• Creating openings for cable glands, conduit and fittings
• Electrical and plumbing installation work
• Workshop and maintenance drilling tasks

Key specifications

• Cutting diameter: 16 mm
• Blade type: bimetal (high-speed steel teeth bonded to flexible steel backing)
• Suitable materials: thin sheet metal, metal pipe walls, and similar substrates where bimetal saws are recommended
• Compatibility: designed for use with standard hole saw arbors and compatible drill chucks
• Typical applications: installations, maintenance, electrical and plumbing work

How to use

Secure the bimetal hole saw to an appropriate arbor and tighten according to the arbor manufacturer’s instructions. Mark the drilling center on the workpiece and clamp the material to prevent movement. Start drilling at low speed to establish the pilot position or use the arbor pilot bit where fitted, then increase speed moderately while applying steady, even pressure. Use light cutting fluid when working with metal to reduce heat and extend blade life. Withdraw the saw periodically to clear chips and allow cooling.

Usage recommendations

Use appropriate personal protective equipment, including eye protection and gloves. Match drill speed and feed to the material thickness; excessive speed or pressure may reduce saw life. For thicker or harder materials consider progressive cuts or a cooling lubricant to prevent overheating. Inspect the teeth before use and replace the hole saw if teeth are chipped or worn.
