Hole saw GRAPHITE 57H900 — single pack, lightweight 18 g

GRAPHITE 57H900 — single pack hole saw is a compact cutting accessory designed for creating round openings in a variety of materials. Supplied as a single unit with a pack weight of 18 g, this lightweight hole saw features bimetal construction and progressive high-speed steel teeth that enable efficient cutting in steel, stainless steel, wood, plastics and composite materials. The tool is intended for use with compatible drills and rotary tools when a precise, compact hole-cutting solution is required.

Advantages

The bimetal design combines toughness and cutting performance for longer service life compared with simple carbon-steel saws. Progressive teeth made of high-speed steel provide quicker penetration and reduced vibration, improving cutting accuracy and edge quality. The single-piece, lightweight format simplifies storage and handling, and the compact weight makes it suitable for portable tool kits where minimal added mass is important.

Suitable for

• Creating round openings in sheet metal and mild steel
• Drilling holes in stainless steel components
• Cutting openings in wood for fixtures and fittings
• Making apertures in plastic panels and composite laminates
• Use with portable drills and rotary tools for on-site work

How to use

Install the hole saw onto a compatible arbor or mandrel according to the drill manufacturer’s instructions and secure it firmly. Mark the center of the intended opening and start drilling at low speed to establish a guide hole, then increase speed and apply steady feed pressure suited to the material. For metal work, use cutting lubricant to extend tool life and improve chip evacuation. Maintain a stable drill angle and avoid excessive radial forces to prevent tool wobble and achieve a clean, round hole.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. For stainless steel and harder metals, apply cutting fluid and moderate speeds; for wood and plastics, higher speeds with controlled feed are acceptable. Inspect the teeth before use and replace the cutter when wear reduces cutting performance or causes excessive vibration.
