The DeWALT DT90352-QZ drill hole saw set contains seven saws designed to cut clean circular holes in metal, plastic and wood. Each saw is engineered for stability and edge retention to achieve accurate holes across common construction and renovation materials. The set supplies a range of diameters to cover typical hole sizes needed for pipe penetrations, cable access, fittings and installation work.

Advantages

The set delivers reliable cutting performance across multiple materials thanks to robust tooth geometry and heat-resistant construction. Included sizes provide flexibility for different tasks, reducing the need to change tools frequently. The saws are compatible with standard arbors and drills, enabling quick setup and consistent centering while maintaining a uniform hole finish.

• General purpose woodworking and metalworking on thin sections

Key specifications

• Material compatibility: metal, plastic, wood
• Set quantity: 7 pieces covering a range of common hole diameters
• Cutting type: circular hole saws with toothed cutting edge
• Connection: fits standard drill arbors and chucks
• Typical usage: through-hole cutting in thin panels, sheet materials and soft metals

How to use

Choose the hole saw size appropriate for the desired opening and attach it to a compatible arbor and drill. Mark the center point on the workpiece, secure the material to prevent movement, and start drilling at low speed to establish the pilot position. Apply steady pressure, allowing the saw teeth to cut without forcing; increase speed gradually once the cut is established. After cutting, retract the saw and remove any plug or debris before finishing the edge as required.

Recommendations

Use cutting lubricant or coolant when drilling ferrous metals to reduce heat and extend cutting life. For abrasive plastics or dense hardwoods, control speed and feed to avoid melting or splintering. Always wear appropriate eye and hand protection and clamp work securely to ensure accurate, safe cutting.
