Best Drill Bits For Plastic: Top Picks And Tips 2026

This DEWALT 14-piece set offers 135° split point tips that bite fast and stay centered. Bits run cooler and reduce chatter, which helps avoid melted or chipped holes. The 3-flat shank gives grip in drill chucks and quick changes. I find them consistent for thin acrylic, PVC, and general shop plastics. The set works for wood and metal too, making it a good all-round kit for makers who need the best drill bits for plastic.
The case keeps sizes sorted. Use slow speed and light pressure with plastic, and these bits make clean holes with low melt risk. They are a top pick for hobbyists.

TITGGI supplies carbide-tipped bits that cut hard surfaces and also work on plastics without chipping when used gently. The industrial tips stay sharp and resist wear, which helps avoid rough edges on acrylic or PVC. I use slow speed and steady feed to keep heat low. These bits are a smart pick when you need the best drill bits for plastic and occasional tile work.
They come in common sizes and fit standard drills. For soft plastics, back off speed; for hard board plastics like polycarbonate, use lubrication or cooling to reduce stress and get cleaner holes.

Amana Tool HSS bits are made for plastic and give clean holes with little tear-out. The 1/8″ size is common for fastener work in acrylic and thin ABS. I use low RPM and steady pressure; the HSS stays cool and cuts smoothly. These are among my go-to picks for the best drill bits for plastic when you need precision in small holes.
The pack of five keeps spares handy. They fit corded and cordless drills and are ideal for electronics enclosures, model work, and small fixtures where clean edges matter.

Craftsman gold oxide bits are an easy choice for everyday shop work on plastic and wood. The coating helps reduce friction and keeps heat down, which lowers the chance of melted rims on plexiglass. I use them at controlled speeds for clean holes. They make good, budget-friendly entries for the best drill bits for plastic when you want coverage across sizes.
The set covers common needs and stores well in a tray. For brittle acrylic, pair with low speed and tape to avoid chipping. These are reliable for light to medium plastic tasks.

This 1/4″ bit is made for hand drills and common plastic types like acrylic, Lexan, and PVC. The geometry yields clean holes with minimal cracking when used at low speed and light pressure. I keep one for hardware holes and mounting tasks because the size fits many fasteners. It’s a focused choice for the best drill bits for plastic when you need a reliable single size.
It performs best on thin to medium plastics. For thick polycarbonate, reduce speed and back out often to clear chips and reduce heat buildup for a clean finish.

The DEWALT 21-piece set expands size range with 135° split points and black oxide coating to reduce friction. This mix helps when drilling varied plastics without melting or cracking. I use lower RPM and steady feed to maintain a cool cut. These bits are among the best drill bits for plastic for users who need both range and reliable starts across sizes.
The helix and point geometry cut clean on thin panels. They also handle wood and metal, which makes them versatile for a shared shop environment. The case keeps parts easy to find.

Aleric step bits make clean, tapered holes in sheet plastics and thin panels. The titanium coat reduces friction and helps keep edges neat on plexiglass and aluminum. I use low speed and steady feed to notch holes without cracking. For tasks needing multiple hole sizes, these are some of the best drill bits for plastic because they cut several sizes with one pass.
They are ideal for control panels and grommet holes. Use backing support under thin sheets to avoid deformation and get smooth rounds without tear-out.

ZELCAN step drill gives a wide size range for quick holes in sheet plastics and thin materials. The HSS body and titanium finish cut smoothly and help keep edges clean on plexiglass. I use backing and low speed to prevent heat and melt, which makes them some of the best drill bits for plastic for panel tasks. They are fast and reduce the need to change bits.
The cone shape is easy to control and centers well. For thick acrylic, take light passes and clear chips often for the best finish.

SOURCEONE bits are purpose-built for acrylic and other clear plastics. The flute form and tip angle reduce cracking and produce smooth edges. I use them at low speeds with firm backing and they give the clean holes that designers need. These are some of the best drill bits for plastic when clarity and edge finish are top priorities.
They work best on cast acrylic and Lucite. For polycarbonate I slow feed and cool frequently. They cost more but save time on finishing work and sanding.

COMOWARE offers a 16-piece titanium twist set with hex shanks for quick changes in cordless drivers. The HSS with titanium finish helps keep heat down and the hex shank makes bit swaps fast. I like these for fast shop work and small plastic parts where speed matters. They are handy among the best drill bits for plastic when you work with many small sizes quickly.
They suit aluminum and softer plastics. Use a drill with clutch control to avoid over-torque and bit breakage for thin materials. The set is compact and travel-ready.
