Hole saw set KWB 598250, 11 pieces — cutting kit for wood, metal and plastic

KWB Hole Saw Set 598250 is an 11-piece cutting kit for creating circular holes in materials such as wood, metal and plastic. The set provides a range of common diameters and includes compatible arbors and pilot drills for use with standard hand drills. It is designed to deliver controlled, clean cuts for installation tasks, electrical and plumbing work, and general DIY applications where round openings are required.

Advantages

The set combines multiple hole saw diameters in a single compact kit to reduce the need for separate purchases. Hardened cutting edges and a balanced tooth design enable efficient material removal and reliable cutting performance across wood, non-hardened metal and plastic. Included pilot drills and arbors improve centering and stability in use, while the kit format keeps components organized and readily accessible.

Suitable for

• Installing door hardware, locks and fittings in wooden doors and panels
• Making cable and conduit entry holes for electrical and low-voltage installations
• Cutting openings for plumbing pipes and fixtures in plastic and thin metal
• General DIY projects requiring precise circular cutouts in wood, plastic or sheet metal

Key specifications

• Contents: 11 pieces including multiple hole saw diameters, arbors and pilot drills
• Material compatibility: wood, non-hardened metal, plastic
• Cutting geometry: toothed hole saws with hardened cutting edges for general-purpose use
• Mounting: compatible with standard drill chucks using supplied arbors and pilot bits
• Storage: supplied in a compact case for organized transport and storage

How to use

Secure the appropriate hole saw to the arbor and tighten according to the arbor manufacturer's instructions. Fit the arbor into the drill chuck and secure the pilot bit to ensure accurate centering. Mark the desired hole position on the workpiece, start drilling at low speed to establish a pilot groove, then increase speed and apply steady, even pressure until the hole saw cuts through the material. For metal or thicker materials, use cutting lubricant and reduce feed speed to avoid overheating. After cutting, remove the core plug and deburr the edge as required.

Usage recommendations

Use appropriate personal protective equipment such as eye protection and gloves. Match hole saw diameter and tooth type to the material being cut, avoid excessive side pressure, and allow the tool to cool during prolonged cutting to extend component life.
