Sierra de corona Bosch PRO Multi Material PC Plus 44/19 mm — unidad suelta para taladro, apta para pladur, metal, metal no férreo, plástico, madera blanda

Single-piece Bosch PRO Multi Material PC Plus hole saw 44/19 mm for use with drills. Designed to create precise round openings in drywall, metal, non‑ferrous metal, plastic and softwood, this 19 mm diameter hole saw is supplied as a single unit intended for installation, wiring, piping and general trade or DIY tasks. The tool combines a high-cobalt HSS tooth design with Bosch Power Change compatibility to deliver consistent cutting performance and straightforward plug removal.

Advantages

The high-speed steel teeth with 8% cobalt provide increased wear resistance and maintain cutting performance across a variety of materials. An enhanced tooth geometry ensures smoother, faster cuts while the single-piece design reduces vibration and improves control during use. Compatibility with the Bosch Power Change Plus arbor allows quick, keyless changes of hole saws and easier removal of material plugs for uninterrupted work.

Suitable for

• Creating openings for electrical boxes and conduit in drywall and plasterboard
• Cutting small-diameter holes in thin metals and non‑ferrous sheets
• Drilling holes for pipe penetrations in installation work
• Making entry holes in plastic panels and softwood trim

Key specifications

• Hole saw diameter: 19 mm
• Construction: single-piece hole saw
• Tooth material: high-speed steel alloy with 8% cobalt
• Compatible arbor system: Bosch Power Change Plus (keyless)
• Intended materials: drywall, metal, non‑ferrous metal, plastic, softwood

How to use

Fit the hole saw to a compatible drill using the Bosch Power Change Plus arbor or another matching arbor. Mark the center of the required opening, position the pilot bit (if used) and start drilling at low speed to establish the cut. Increase speed as needed while applying steady pressure; avoid forcing the tool. After cutting, stop the drill and remove the plug by using the Power Change quick-release function or by carefully prying the cut material free when the tool is stationary.

Recommendations

Use appropriate personal protective equipment, including eye protection and gloves. For metal work, secure the workpiece and use cutting lubricant if recommended for the specific metal. For drywall and plastic, control dust and clear debris from the hole saw regularly to maintain cutting efficiency.
