Hole Saw, Bosch Bi‑Metal, Single, 14 mm diameter, for drill, drywall/metal/plastic/softwood

Bosch Bi‑Metal hole saw, single piece with 14 mm diameter, is designed for use with standard drills to create precise small holes in drywall, metal, plastic and softwood. The bi‑metal construction combines a hardened cutting edge with a flexible body to maintain cutting performance across different materials and reduce the risk of breakage. Intended for tasks such as drilling entry points for cables, pipes or fittings in construction and DIY work.

Advantages

The 14 mm Bosch Bi‑Metal hole saw provides smooth cutting action thanks to its vario tooth strip and bi‑metal HSS construction. The use of a cobalt‑containing HSS alloy enhances wear resistance and blade life while the bi‑metal design offers flexibility to resist fracture under load. Compatibility with standard hole saw adapters simplifies replacement and use with common drill setups. The product is supplied as a single piece for straightforward selection when a small diameter hole is required.

Suitable for

• Cutting precise small holes for electrical cables and conduits in drywall
• Drilling through thin ferrous and non‑ferrous metal sheets
• Making openings in plastic panels and housings
• Creating small holes in softwood for fittings and guide points

How to use

Fit the Bosch 14 mm bi‑metal hole saw onto a compatible arbor or adapter and secure it to a drill according to the adapter manufacturer’s instructions. Mark the drilling position, start drilling at low speed to establish the pilot engagement, then increase speed as appropriate for the material. Apply steady, moderate pressure and allow the saw to cut without forcing; withdraw periodically to clear chips when cutting metal or plastic. After use, clean swarf from the teeth and store the hole saw in a dry place.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. For metal work, apply cutting lubricant to reduce heat and extend tool life. Match drill speed to material—lower speeds for metals, higher speeds for drywall and plastic—and avoid excessive side pressure to prevent premature wear or damage.
