Silverline Bi-Metal Holesaw Variable Pitch Hole Saw 92mm 675180

Silverline Bi-Metal Holesaw Variable Pitch Hole Saw 92mm

Barcode: 5055058165589

MPN: 675180

Size: 92mm

Overview:

Bi-Metal Holesaw Variable Pitch Hole Saw (92mm) 675180 is a heavy-duty cutter designed for fast, controlled hole cutting in a wide range of materials. Hardened HSS teeth deliver clean cutting performance, while the flexible high-carbon steel backing improves strength and helps resist cracking under load. The variable pitch tooth pattern reduces vibration and snagging, making it a dependable option for larger diameter holes in metal, plastics and timber (task dependent). The 92mm size is clearly marked on the body for quick identification, making it ideal for installation work, fabrication and general workshop use.

92mm Bi-Metal Holesaw 675180 – Key FAQs

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

• Why is variable pitch useful?
  Variable pitch tooth spacing helps reduce vibration and snagging, giving smoother cuts and better control across different materials.

• What materials can I cut with this 92mm 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 92mm size marked on the holesaw?
  Yes, the size is clearly marked on the body for quick and easy identification.

• Does this include the arbor?
  No—this is the holesaw only. A compatible arbor is required and is typically sold separately.

• How do I get a cleaner cut in metal?
  Use a slower drill speed, keep the holesaw square, apply cutting fluid and clear swarf regularly to help prevent overheating.
