Hole saw GRAPHITE 57H903, single-piece, 57H903 model, pack of 1, 60 g

GRAPHITE 57H903 hole saw is a single-piece cutting tool supplied as one unit with a compact, lightweight design. Built for making circular openings in a variety of common materials, this hole saw features a bimetal construction and progressive high-speed steel teeth to deliver efficient cutting performance and reliable hole quality for installation, repair and general workshop tasks.

Advantages

The bimetal construction combines flexibility and wear resistance to extend tool life when working with mixed materials. Progressive high-speed steel teeth reduce cutting effort and improve chip evacuation, resulting in smoother cuts and reduced heat buildup. Its single-piece configuration is compact and easy to handle, making it suitable for confined workspaces and straightforward transport. The tool's lightweight design simplifies manual use and reduces operator fatigue during short cutting jobs.

Suitable for

• Cutting circular holes in steel and stainless steel
• Creating openings in wood and plywood
• Working with plastics and composite panels
• Installation and repair tasks requiring compact cutting tools

Key specifications

• Construction: bimetal blade with high-speed steel teeth
• Tooth geometry: progressive tooth pitch for efficient cutting
• Weight: approximately 60 g (pack weight)
• Configuration: single-piece hole saw supplied as one unit

How to use

Secure the hole saw to a compatible arbor or drill adapter according to the arbor manufacturer's instructions and ensure the drill is fitted with appropriate speed and torque settings for the target material. Mark the centre point of the intended opening and start drilling at low speed to establish the pilot position, then increase speed as appropriate while applying steady, even pressure. Use cutting fluid or lubricant when working with metals to reduce heat and extend tool life. Clear chips periodically to maintain cutting efficiency and avoid binding.

Usage recommendations

For best results, select drill speeds and feed rates suitable for the material being cut: lower speeds for stainless steel and harder alloys, medium speeds for general steels, and higher speeds for wood and plastics. Maintain sharpness by avoiding excessive side loads and overheating; replace the tool if teeth become dull or damaged. Always use appropriate personal protective equipment, secure the workpiece, and follow safe drilling practices.
