BAHCO 3830-51-VIP is a single 51 mm hole saw designed for use with hand-held and bench-mounted drills. Part of the Sandflex® bi-metal range, this hole saw combines a hardened cutting edge with a flexible body to cut clean circular openings in panels, pipes and various workpieces. Its geometry and bi-metal construction make it suitable for cutting a wide range of materials including metal, stainless steel, steel, plastic and wood. Supplied as one unit in a box, the tool is intended for installers, fabricators and tradespeople who need a compact, drill-mounted solution for through-holes and fixture openings.

Advantages

The Sandflex® bi-metal design delivers a balance of cutting speed and durability, reducing the need for frequent blade changes. Optimized tooth geometry helps produce smooth hole edges and reduces burr formation when cutting metals and plastics. The single-piece supply in protective packaging facilitates secure storage and easy identification on the jobsite. Compatibility with common drill arbors and straightforward mounting makes it a practical choice for both portable and stationary drilling setups.

• Compatible drive: drill-mounted hole saw (requires appropriate arbor)
• Material suitability: metal, stainless steel, steel, plastic, wood
• Supply: single unit in a box

How to use

Fit the hole saw to a suitable arbor and secure it in the drill chuck according to the drill and arbor manufacturer instructions. Mark the centre point of the hole on the workpiece and, if possible, clamp the workpiece to prevent movement. Start drilling at low speed to establish the pilot and maintain steady pressure; increase speed as appropriate for the material. Use cutting fluid when working with metals or stainless steel to reduce heat and extend tool life. After completing the cut, remove the slug carefully and deburr the hole if necessary.

Usage recommendations

For best results when cutting metals and stainless steel, use cutting lubricant and moderate feed pressure. When working with wood or plastic, higher speeds and lighter feed can improve finish. Inspect the saw before use for damage and replace if teeth are worn or bent. Always follow safety guidelines for eye protection, clamps and proper drill handling.
