## Summary description

Bimetal hole saw AWTools OTWORNICA BIMETALOWA HSS-Co 8% with 30 mm cutting diameter from the Black Line series.

Suitable for use with drills and arbors in metalworking and general maintenance tasks.

## Long description

AWTools OTWORNICA BIMETALOWA HSS-Co 8% 30 mm Black Line is a bimetal hole saw designed for cutting clean, precise holes with a 30 mm diameter. Manufactured from high-speed steel with 8% cobalt, this hole saw provides improved heat resistance and extended cutting life compared with standard HSS tools. The Black Line finish helps reduce friction and supports stable cutting performance when working with a range of materials, notably metals and other tough substrates. It is intended for use with standard drills and arbors in metalworking, installation, and maintenance tasks.
Advantages
The bimetal construction combines a flexible backing with a hardened cutting edge to resist chipping and premature wear while maintaining toughness. The 8% cobalt content increases red-hardness, allowing the tool to retain hardness at higher cutting temperatures for longer continuous operation. The 30 mm diameter offers a practical size for conduit, pipe, and fitting holes, and compatibility with common drill arbors makes the saw easy to integrate into existing tool sets.
Suitable for
 Cutting holes in mild and stainless steels
 Creating openings in sheet metal and thin-walled pipes
 Installation of electrical fittings, conduits and plumbing penetrations
 General maintenance and metal fabrication tasks requiring durable hole cutting
Key specifications
 Cutting diameter: 30 mm
 Material: bimetal high-speed steel with 8% cobalt (HSS-Co)
 Series/finish: Black Line
 Compatibility: designed for use with drills and standard hole saw arbors
 Intended applications: metalworking, installation, maintenance
How to use
Mount the hole saw on a compatible arbor and secure it to the drill according to the arbor manufacturer's instructions. When cutting, clamp the workpiece firmly and mark the hole center before starting. Use a steady, moderate feed rate and start at a low drill speed, increasing speed as the saw engages the material. Apply cutting fluid or lubricant when working with metals to reduce heat buildup and improve cutting life. Periodically withdraw the saw to clear chips and allow cooling.
Usage recommendations
For best results, select an arbor that provides secure centring and sufficient pilot guidance. Use appropriate personal protective equipment, such as eye protection and gloves, and ensure the workpiece is stable. Avoid excessive feed pressure; let the saw cut at its designed rate to prolong life. Regularly inspect the cutting edge and replace the saw when wear or tooth damage affects performance.
