Hole Saw Irwin bimetal 24 mm model 10504168 for drilling metal and wood

Irwin bimetal hole saw 24 mm (model 10504168) is a circular cutting tool designed to create precise 24 mm holes in a variety of materials including metal and wood. The bimetal construction combines high-speed steel teeth with a flexible alloy body to provide improved durability and resistance to heat during intensive drilling. The hole saw is compatible with standard arbor holders and intended for use with hand drills and drill presses where a clean, round opening is required.

Advantages

The bimetal tooth design offers a balance between toughness and cutting performance, reducing tooth breakage and extending tool life compared with carbon-steel alternatives. Its 24 mm diameter delivers consistent hole size for fittings and fasteners, while the reinforced body maintains shape under torque. Heat-resistant cutting edges help preserve hardness during continuous work on metal, and the saw’s geometry supports efficient chip evacuation to prevent clogging.

Suitable for

• Creating 24 mm holes in thin and medium-thickness metal sheets
• Cutting holes in soft and hard wood
• Installing plumbing and electrical conduits or pipe fittings
• Workshop repair tasks and fabrication where accurate round openings are required

Key specifications

• Cutting diameter: 24 mm
• Material of teeth: high-speed steel (bimetal construction)
• Body material: flexible alloy backing for impact resistance
• Compatibility: standard arbor/drill chuck mounting
• Suitable for: metal and wood

How to use

Secure the hole saw to a compatible arbor and tighten in the drill chuck according to the drill manufacturer’s instructions. Mark the center point of the hole and, if necessary, use a center punch to prevent walking. Start drilling at low speed to establish the pilot position, then increase speed as appropriate for the material. Apply steady, even pressure and allow the saw to cut without forcing; periodically withdraw the saw to clear chips and allow cooling when cutting metal. After completing the cut, remove burrs from the hole edge as needed.

Usage recommendations

Use appropriate cutting fluid or coolant when drilling metal to extend the life of the bimetal teeth. Wear eye and hand protection, clamp workpieces securely, and select drill speed according to material thickness to ensure safe and accurate results.
