GRAPHITE 57H901 — 1 pc, lightweight cutting accessory for drilling is a single-piece hole saw designed for creating precise circular openings when used with a drill or drill driver. The hole saw is supplied as one unit with a compact net weight of 36 g and features a bimetal construction with progressive high-speed steel teeth. It is suitable for cutting through a range of materials including steel, stainless steel, wood, plastics and composite materials, making it a practical tool for installation, plumbing, electrical and general DIY tasks that require accurate round holes.
Advantages
The bimetal design combines flexibility and durability, while progressive high-speed steel teeth provide efficient cutting performance and extended tool life. Its lightweight, single-piece construction simplifies handling and reduces fatigue during repeated use. The tool is manufactured to produce clean edges and accurate diameters, which reduces the need for secondary finishing. Compatibility with common drills and drill drivers makes it easy to integrate into existing tool sets.
Suitable for
- Installing plumbing fixtures and pipe penetrations

How to use
Secure the hole saw to an appropriate arbor or mandrel and attach it to a drill or drill driver according to the drill manufacturers instructions. Mark the centre of the hole on the workpiece, start drilling at low speed to establish the pilot and then increase speed to cut through the material, applying steady, even pressure. For metal work, use suitable cutting oil or lubricant to reduce heat and extend tool life; for wood and plastics, ensure the workpiece is clamped and supported to prevent splintering. After cutting, remove burrs if necessary and inspect the hole for required fit and finish.
Usage recommendations
Use appropriate personal protective equipment such as safety glasses and gloves. Match drill speed and feed pressure to the material being cut; reduce speed for stainless steel and increase for softer materials. Regularly clear chips from the cutting area and replace the hole saw if performance declines to maintain clean, accurate cuts.
