BI-METAL HOLESAW SET FOR PLUMBER 19MM-57MM ROSSEL 8536 (9PCS/SET) (10SETS/CTN)

Product Description

The Rossel Bi‑Metal Holesaw Set (Model 8536) is a professional‑style cutting accessory kit designed for plumbing, electrical and general installation work. This set includes multiple bi‑metal holesaws in commonly used plumber sizes — from 19 mm up to 57 mm — and comes with the necessary arbors and adapters so you can drill clean round holes in sheet materials during fit‑outs. Bi‑metal holesaws combine high‑speed steel cutting teeth with a flexible steel body for durability and long service life. Sets like these are commonly used by plumbers and tradespeople for cutting holes in metals, plastics, wood and other construction materials.

Key Benefits and Features

• Bi‑metal construction: High‑speed steel (HSS) teeth welded to a flexible alloy body help resist wear and provide long cutting life for frequent use.
• Designed for plumbers: Includes sizes most used in plumbing, heating and pipe‑fitting tasks — ideal for hole‑outs for valves, pipe runs, couplings and access points.
• Versatile material use: Effective on sheet metal, mild steel, aluminium, copper, PVC, wood and drywall when using the correct drill speed and lubrication (where required).
• Chip‑clearing slots: Side slots in the saw cups help eject cut material and reduce binding while drilling.
• Comprehensive kit: Usually supplied in a compact carry case with the arbors, pilot drills and any required hex keys or adapters (varies by supplier, but standard for plumber sets).

Usage Tips: For the best results when cutting metal, run the drill at moderate speed and use light cutting oil to reduce heat build‑up and extend the life of the holesaws. When cutting wood or PVC, higher speeds can be used and chip ejection is faster.
