Prox BI-metal hole saw 51 mm HSS and M2 carbon steel M14 thread HEX mounting depth 34 mm for steel stainless steel wood plastic

The Prox bi-metal hole saw 51 mm is a versatile cutting tool designed for clean and efficient drilling across a wide range of demanding materials. Constructed from a durable combination of high-speed steel (HSS) and M2 carbon steel, this hole saw delivers reliable performance and wear resistance for various workshop and maintenance tasks. It features an M14 thread and a HEX mounting system, allowing for secure attachment to compatible power tool setups. With a specific diameter of 51 mm and a maximum drilling depth of 34 mm, it handles medium-depth cuts with precision.

Advantages

The bi-metal construction combining HSS and M2 carbon steel provides enhanced durability and resistance to high temperatures generated during continuous cutting operations. This material pairing ensures that the cutting edge remains sharp longer, reducing the frequency of tool replacements. The inclusion of an M14 thread and HEX mounting facilitates stable installation and quick changes. Its multi-material capability makes it a versatile addition to any tool collection, eliminating the need for multiple specialized bits when switching between metal, wood, and plastic applications.

Suitable for

• Drilling holes in structural steel and stainless steel sheets
• Cutting through non-ferrous metals and aluminum
• Creating openings in various types of wood and timber
• Boring holes in plastic sheets and synthetic materials

When it may not be suitable

This hole saw may not be suitable for heavy-duty industrial drilling operations that require cutting depths significantly greater than 34 mm. It is also not designed for masonry, concrete, stone, or hardened tool steels, as these materials can rapidly damage the bi-metal teeth.

Key specifications

• Diameter: 51 mm
• Drilling depth: 34 mm
• Material composition: HSS and M2 carbon steel
• Mounting type: HEX mounting with M14 thread

How to use

To use the Prox bi-metal hole saw, first ensure it is securely mounted to your power tool using the appropriate M14 thread and HEX adapter. Mark your drilling center clearly on the workpiece. Start drilling at a low to moderate speed, applying steady and even pressure to prevent overheating. For metal applications, the use of a suitable cutting fluid or lubricant is recommended to extend the lifespan of the HSS and M2 carbon steel teeth. Retract the saw periodically to clear out debris and chips from the cut.

What to consider before purchase

• Verify that your power tool supports the M14 thread and HEX mounting system
• Check that the 51 mm diameter and 34 mm depth match your specific project requirements
• Ensure you have the appropriate cutting fluids if planning extensive metal drilling

Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses and gloves, when operating cutting tools. Secure the workpiece firmly before beginning any drilling operation to prevent slipping or binding.
