Hole saw GRAPHITE 57H924 bi-metal 57 mm, 1 pc

GRAPHITE 57H924 drill hole saw is a bimetal cutter with progressive teeth made from high-speed steel designed for cutting precise holes in a range of materials. The tool is supplied as a single unit with a compact weight suitable for handheld and machine-mounted use.

Advantages

The bimetal construction combines a flexible body with high-speed steel cutting edges for improved durability and resistance to wear. Progressive teeth geometry reduces cutting resistance and improves chip evacuation, enabling cleaner holes and longer life compared with simple tooth designs.

Suitable for

• Cutting holes in mild steel and stainless steel
• Drilling through wood and plywood
• Working with plastics and composite panels

When it may not be suitable

This hole saw is intended for general-purpose metal and wood cutting. It may not be suitable for continuous heavy-duty production on very hard alloys or for cutting reinforced concrete and masonry. For tasks requiring extremely high precision finishes, additional reaming or sanding may be needed after cutting.

Key specifications

• Type: Bimetal hole saw with progressive teeth
• Cutting material: High-speed steel teeth
• Diameter: 57 mm
• Pack quantity: 1 piece
• Weight: 138 g

How to use

Mount the Graphite 57H924 hole saw on a compatible arbor and secure it in the drill chuck. Start drilling at low speed to create a guide, then increase speed as appropriate for the material. Apply steady, moderate pressure and allow the teeth to cut without forcing the tool. For metal cutting, use cutting fluid to reduce heat and extend tool life. Clear chips from the cutter periodically to maintain cutting efficiency.

What to consider before purchase

• Confirm the 57 mm diameter matches the required hole size for your project
• Ensure your drill and arbor support bimetal hole saws of this diameter
• Consider cutting speed and use of cutting fluid for metal applications

Usage recommendations

The Graphite 57H924 performs best when used with a suitable arbor, at appropriate speeds for the material, and with intermittent clearing of chips; apply cutting fluid when drilling metals to improve life and hole quality.
