Hole saw BAHCO 3830-24-VIP, diameter 24 mm, bi-metal cutting cup

BAHCO 3830-24-VIP is a 24 mm diameter bi-metal hole saw designed to cut accurate circular holes in a variety of materials. The Sandflex® bi-metal construction with cobalt-enhanced alloy increases wear resistance and thermal stability, making the tool suitable for metal, wood and plastic. Compact and lightweight, this hole saw fits standard arbor systems and is intended for professional installers, electricians and maintenance work.

Advantages

The Sandflex® bi-metal design combines flexibility and hardness to extend tool life and resist heat during intensive drilling. Knockout holes in the cutting cup enable straightforward removal of the core after cutting, reducing downtime. The hole saw is compatible with both stationary and portable power drills and is engineered for consistent hole size and reliable performance in repeated use.

Suitable for

• Cutting holes in ferrous and non-ferrous metals, including stainless steel
• Drilling circular openings in wood and wood-based materials
• Creating passages in plastic and composite panels
• Installation tasks for electricians, plumbers and HVAC technicians
• Maintenance and repair work requiring precise round holes

How to use

Choose a suitable arbor that matches the hole saw and secure the hole saw to the arbor according to the arbor manufacturer’s instructions. Mark the center of the hole, pilot with a center drill or use the arbor pilot where applicable, and set the drill to an appropriate speed for the material being cut. Apply steady pressure and allow the teeth to cut without forcing; use cutting fluid when working with metals to reduce heat and prolong tool life. After completing the cut, use the knockout holes to remove the core safely.

Usage recommendations

For best results when cutting metals, use cutting fluid and moderate drill speeds. When drilling wood or plastics, higher speeds and reduced feed pressure can improve chip evacuation. Inspect the hole saw before use for damage and replace if teeth are worn; always follow safety guidelines for eye and hand protection.
