Hole saw bi-metal Dedra 60 mm (2-3/8") for wood and metal, model 08W060

The Dedra bi-metal hole saw 60 mm (2-3/8") model is a circular cutting tool designed for creating clean, accurate holes in wood, metal and thin-walled materials. Its bi-metal construction combines high-speed steel cutting edges with a flexible alloy body to provide wear resistance and improved heat tolerance during drilling. The hole saw is compatible with standard drill drivers and drill presses and is intended for tasks such as installing pipes, conduits and door hardware or making larger boreholes efficiently.

Advantages

Bi-metal construction ensures a balance between toughness and cutting performance, reducing the risk of tooth breakage while maintaining sharpness. The 60 mm diameter gives a common, practical size for many installation tasks. The design allows for efficient chip evacuation and reduced overheating, enabling longer cutting periods in wood and thin metal sheets. Compatibility with common arbors and drills makes it a versatile choice for workshop and on-site work.

Suitable for

• Cutting circular holes in timber, chipboard and plywood
• Drilling through thin sheet metal and light-gauge steel
• Creating openings for pipes, conduits and cable glands
• Preparing holes for door hardware, locks and fittings
• Rapid removal of material when a larger bore is required

Key specifications

• Cutting diameter: 60 mm (2-3/8")
• Material: bi-metal (high-speed steel teeth bonded to alloy body)
• Intended materials: wood, wood-based panels, thin-walled metal sheets
• Mounting: compatible with standard drill driver or drill press arbors
• Cut type: circular hole for through-holes and penetrating cuts

How to use

Fit the hole saw to a suitable arbor and secure it in a drill or drill press chuck. Mark the center of the intended hole and, if needed, use a pilot drill to start accurately. Position the pilot bit square to the work surface and begin drilling at low speed to establish the cut, then increase speed as appropriate for the material. Apply steady, moderate pressure without forcing the tool; allow the saw teeth to cut and the chips to evacuate. For metal work, use cutting lubricant and periodically withdraw the saw to clear swarf and reduce heat buildup. After cutting, remove the plug from the hole saw and deburr the hole edges as necessary.

Usage recommendations

Use appropriate personal protective equipment such as eye protection and gloves. Select drill speed and lubricant according to the material: lower speeds and cutting oil for metals, higher speeds for softwoods. Ensure the workpiece is clamped securely and that the drill is held steady to avoid wandering. Regularly inspect the teeth for wear and replace the hole saw if teeth are damaged or cutting performance declines.
