Drill Bit Finder | Drilling Plastic

Plastic can melt, crack, or splinter if drilled incorrectly. Choosing the right drill
bit — and using it at the right speed — makes all the difference. We’ve listed
the three best options below, depending on your hole size and application.

Excellent for drilling clean, accurate holes in plastic sheet, panels, and enclosures.

Step drills cut progressively, reducing grab and preventing cracking or splintering. They also deburr as they cut, making them ideal for plastics such as PVC, acrylic, and polycarbonate.

Use at low speed with light pressure for best results.

HSS DRILL BITS

Standard HSS drills are suitable for plastic when used at controlled speed and light pressure.

Their smooth cutting action helps prevent melting and tearing, especially in thinner plastics. Ideal for small to medium holes where precision matters.

Avoid high speed and excessive pressure to reduce heat build-up.

Bi Metal Hole Saw

Designed for cutting larger-diameter holes in plastic sheet and panels.

Best used at low speed with steady pressure to avoid heat build-up and melting. Suitable for junction boxes, enclosures, ducting, and electrical fittings where clean openings are required.
