Hole saw DeWalt DT90303-QZ — 1 pc, bi-metal cutting cutter for drills

DeWalt DT90303-QZ bi-metal hole saw, supplied as a single piece, is designed for cutting holes in wood, metal and plastic with a compatible drill. The bimetal construction and patented tooth geometry improve chip evacuation and extend tool life, while the deep-cut design enables single-pass cuts through 2-by dimensional lumber and accommodates thicker materials up to 44 mm.

Advantages

The patented tooth forms optimize chip removal to reduce clogging and heat build-up, resulting in more efficient drilling and longer tool life. A large continuous slot allows fast plug ejection and easy removal, minimizing downtime. The High Speed Steel (HSS) cutting edge provides reliable performance across wood, metal and plastic, and the deep hole saw geometry is intended for thicker workpieces.

Suitable for

• Installation and carpentry work requiring clean circular holes in 2-by lumber
• Plumbing and electrical tasks that involve cutting holes in metal or plastic pipes and panels
• General-purpose drilling through wood, metal and plastic with a compatible arbor

How to use

Securely mount the hole saw to a compatible arbor and ensure the pilot bit is centered on the workpiece. Select appropriate drill speed and apply steady pressure for the material being cut. Use cutting fluid or coolant when drilling metal to reduce heat and prolong tool life. After cutting, use the large continuous slot to leverage and eject the plug, then clear chips before making the next cut.

Usage recommendations

Match the hole saw size to the application, clamp the workpiece firmly, and use a drill with sufficient power and torque. For metal use cutting fluid and moderate speed; for wood or plastic use higher speeds and steady pressure. Inspect the HSS edge for wear and replace the hole saw when cutting performance declines.
