Hole saw BAHCO 3830-57-VIP Ø57 mm, single piece, for drill, metal/plastic/wood/stainless steel

BAHCO 3830-57-VIP is a single-piece Sandflex® bi-metal hole saw with a nominal diameter of 57 mm designed for use with hand-held and stationary drills. The tool is intended for cutting clean circular holes in a variety of materials including steel, stainless steel, non-ferrous metals, plastics and wood. Supplied as a single unit in a box, this holesaw offers a maximum cutting depth of 38 mm and is suitable for installation, plumbing, HVAC and general workshop tasks that require precise round openings.

Advantages

The Sandflex® bi-metal construction contains 8% cobalt to increase wear resistance and deliver prolonged life when cutting hard materials. The single-piece design and accurate tooth geometry provide stable cutting performance and consistent hole size (nominal size +1.5 mm / -0.0). Knockout holes facilitate easy removal of the material core, and the product is compatible with standard arbors for use in both portable and stationary drills. Overall the holesaw is engineered for precision, durability and repeated professional use.

Suitable for

• Cutting holes in stainless steel and ferrous metals for pipework and HVAC fittings
• Creating openings in wood and plastic for electrical and installation work
• Workshop tasks requiring repeatable, precise circular cuts
• Plumbing and general installation where strong, wear‑resistant cutting edges are needed

How to use

Secure the appropriate arbor and pilot where required, then mount the BAHCO 3830-57-VIP hole saw on a compatible drill. Clamp the workpiece to prevent movement and start cutting at low speed to establish the pilot position, then increase speed and apply steady, even pressure. For metal cutting, use cutting fluid to reduce heat and extend tool life; for wood and plastics, clear chips regularly to avoid clogging. After cutting, use the knockout holes to push out the core safely.

Usage recommendations

For best results when cutting stainless steel or thick ferrous materials, run the drill at moderate speed with cutting lubricant and avoid excessive pressure to prevent overheating. Regularly inspect teeth for wear and replace the holesaw when tooth sharpness or hole accuracy deteriorates. Store dry and keep the protective leaflet/packaging to preserve the cutting edge during transport.
