9 Best Drill Bits For Plexiglass in 2026

Engineered specifically for acrylic and plexiglass, the Craftics bit’s geometry prevents grabbing and cracking in delicate materials. It is designed for use with hand drills, making it a straightforward tool for creating clean holes in plastic sheets. This focus makes it a practical choice for fabricators needing reliable performance on plastics without the risk of damage.

The clear limitation is the single size; you’ll need to buy a set like the Craftics 8-Piece Kit or the Viking Drill & Tool set if your project calls for multiple hole diameters. For the craftsman who works primarily with 1/8″ fasteners or pilot holes, however, this bit’s dedicated design and consistent quality deliver a clean, professional result that general-purpose bits can’t match.

Eight graduated drill bit sizes cover a wide range of hole diameters for acrylic and thermoplastics, so you can handle most fabrication tasks with one kit. Its modified point angle is engineered specifically to prevent cracking and chipping, which solves the grabbing and shattering common with standard metal bits. This geometry makes it compatible with materials like acrylic, polycarbonate, PVC, and PETG for projects such as display cases, signage, and enclosures.

This set is designed specifically for acrylic and thermoplastics like PVC and PETG, not for general-purpose drilling in wood or metal. Its value comes from delivering clean holes in plastic substrates, a task where standard drill bits often fail. For workshops where plastic fabrication is a core activity, the focused geometry and precision tolerances support consistent results across sheet goods and custom parts.

This 14-piece set uses a 135-degree split point tip to help reduce walking, a feature that matters when starting a hole in hard or slick surfaces. High-speed steel construction allows it to be used in plastic, wood, and metal, making it a single kit for diverse materials instead of requiring separate specialized bits.

Its general-purpose high-speed steel construction differs from the dedicated 60-degree geometry found in bits like those from the Viking or MIGG sets listed for acrylic. The 3-flats shank on sizes larger than 3/16-inch reduces spin-out in the chuck, which helps maintain a secure grip during demanding tasks.

The 135-degree split point is the key here, it bites into plexiglass without skating across the slick surface, giving you control from the first touch. This bit is built for the specific, frustrating task of cleaning up or carefully enlarging an existing hole in acrylic without cracking it. Its cobalt makeup fights the heat buildup that melts plastic, and the step design lets you incrementally increase the diameter with one tool. If your project involves modifying pre-drilled plexiglass or sheet metal, this focused tool eliminates guesswork.

This is a single 3/16″ step drill bit, so you are buying a specific size for precise hole enlargement rather than a set of various diameters. Its cobalt construction and stepped design are intended for a range of materials like steel, metal, and acrylics, which makes it a versatile specialist for metal and plastic fabrication tasks. According to the product description, the 135-degree split point tip is meant to prevent walking, aiding in starting on curved or uneven surfaces.

Viking’s bits feature a 60-degree precision-ground point designed to avoid chipping acrylic, which means they are engineered to cut into this material without grabbing and cracking it. This specific geometry makes the set a prime candidate for anyone regularly drilling plexiglass or acrylic sheets. The product is marketed as a chipfree solution for acrylic.

At 7.1 inches long, these bits can introduce more flex and may be excessive for thin stock. Compared to the 2.6-inch Craftics 1/8″ bit, the Viking set is a workshop fixture rather than a pocket-sized tool. You are getting a dedicated kit for repeated, chip-free drilling in acrylic, not a general-purpose bit for mixed materials.

A zero-degree rake angle on the cutting edge eliminates grabbing when the drill breaks through, preventing the sudden jerk that can crack acrylic sheets. This geometry pairs with a 60-degree point to reduce initial pressure, focusing the set’s design on clean entry and exit in plastics. Seven fractional sizes from 1/8 to 1/2 inch are made from M7 HSS steel and come in a steel index case marked with each size.

The trade-off is in specialization. This is a focused kit for acrylic, not a general-purpose collection. You get seven key sizes, but a woodworker needing tiny pilot holes might find the 1/8-inch starting point too large and prefer a set like the KODIVEX brad points that include smaller diameters. For dedicated acrylic fabrication, however, the MIGG set’s deliberate design choices, like the reduced shanks on larger bits for compatibility with standard chucks, prioritize clean results over sheer quantity.

The KODIVEX set’s brad point and double-flute design are the keys to clean work on plexiglass. That sharp, centered tip bites in without walking, and the flutes evacuate chips cleanly to prevent the heat and grabbing that cause cracks and ugly burrs. This makes it a fantastic choice for the woodworker or DIYer who frequently switches between materials like hardwood, plywood, and acrylics, and wants one set that can handle it all without needing a second polish.

This set’s versatility is its main advantage, with a design that handles wood, plastic, and acrylic for burr-free results. For tasks focused only on plexiglass, a specialized option like the Viking Drill & Tool set exists, but the KODIVEX set covers a full range of sizes for general workshop use.

A hex shank that locks securely into any standard drill chuck means you can swap bits without fumbling, a real time-saver when moving between pilot and final holes in a project. This set is for the DIYer or carpenter who values speed and clean starts in wood and plastic, with a brad point that bites exactly where you place it and a five-piece range that handles most common drilling tasks without clutter.

This five-piece set covers the most common hole sizes for woodworking, so you can tackle most furniture and carpentry tasks without a bulky collection. Its sharp brad point tip starts holes precisely where you mark them, which eliminates wandering and splintering on the surface. A quick-change hex shank locks securely into standard drill chucks for fast, slip-free swaps. The bits are engineered for rapid drilling and efficient chip ejection in hardwood, softwood, plywood, MDF, and plastic.

This 13-piece set of HSS brad point bits features a 1/4″ hex shank and a black gold coating. The shank allows for quick changes in a drill chuck, while the coating helps it handle the friction of drilling into hardwoods. That makes it a solid choice for woodworkers who need clean, accurate holes in materials like oak, maple, or plywood without splintering. The brad point tip centers itself neatly, and the ground body cuts smoothly. You get professional results on cabinetry or furniture projects where tear-out is a real concern.

Where this set falls short for our guide is its focus. The manufacturer’s own description targets natural and engineered woods, not plastics. Drilling plexiglass requires a specific bit geometry, typically a 60-degree included angle, to melt through the material without grabbing and cracking it. A standard brad point bit, while excellent for wood, can easily chip or shatter a plexiglass sheet. For that specific task, you’d be better served by a dedicated set like the Viking Drill & Tool 32274, engineered from the ground up for acrylic.
