The HSS bi‑metal holesaw blade, 32mm is a circular cutting cup designed for making clean, repeatable holes in a wide range of materials using a powered drill or holesaw arbor. Its primary use is to cut 32mm diameter apertures for plumbing, electrical conduit, pipework, cable glands and general service penetrations in sheet materials and panel work.

This holesaw is manufactured with high speed steel cutting teeth (M42 grade to ISO 4957) electron‑welded to a flexible alloy steel body to combine sharpness and resilience. The blade is heat‑treated for edge retention and supplied with an anti‑corrosion oxide finish to reduce rusting in storage and on site. The cutting face features precision‑ground teeth in a bi‑metal configuration to maintain cutting performance and resist work‑hardening. The blade fits standard holesaw arbors and will accept common pilot drills; it is compatible with drill chucks and quick‑change hex arbors when used with the appropriate adaptor. Typical arbor thread compatibility for consumer and trade arbors is 5/8"‑11 UNC; adaptors are available for 1/2" and other common systems.

In practical terms the 32mm bi‑metal holesaw is suitable for cutting mild steel and non‑ferrous metals, stainless steel up to moderate thicknesses (typically to around 6mm depending on feed and cooling), aluminium, GRP, plastic, plywood, MDF and plasterboard. Typical industries and trades that use this blade include plumbing and heating, electrical installation, HVAC, fabrication workshops and general maintenance and fit‑out.

Key benefits of the bi‑metal construction are improved wear life compared with carbon steel holesaws, good resistance to heat and edge breakage from the M42 teeth, and a flexible body that resists deformation in demanding use. The 32mm size is widely compatible with standard arbors and pilot drill arrangements, making it easy to integrate into existing toolkits.

Duchy Fasteners stocks this 32mm holesaw as a single blade and supplies a wide range of holesaw sizes and pack options to suit trade and industrial needs, with adaptors and pilot drills available separately. For specific quantities and arbor compatibility please contact our sales team.
