25mm Bi-Metal Holesaw 595768 – Key FAQs

• What does “bi-metal” mean on a holesaw?
  Bi-metal holesaws combine hardened HSS teeth for cutting with a flexible high-carbon backing for strength and resistance to cracking.

• What is variable pitch and why does it matter?
  Variable pitch means the tooth spacing changes around the saw, helping to reduce vibration, improve cutting smoothness and minimise snagging in different materials.

• What materials can I cut with this 25mm holesaw?
  It’s suitable for many materials including steel, stainless, cast iron, aluminium, copper, PVC, acrylic and wood, depending on correct speed and technique.

• Is the size clearly marked?
  Yes, the 25mm (1") size is specified on the side for quick identification.

• Do I need an arbor included?
  This listing is for the holesaw only—use a compatible arbor (sold separately) to fit it to your drill.

• How do I get the cleanest cut?
  Start slowly, keep the drill square, use the right speed for the material, and clear swarf regularly—using cutting fluid on metal also helps.
