Drill Bit — .437" is a precision drill bit designed specifically for drilling plastics and similar materials where clean holes and reduced cracking are important. Manufactured from hardened steel, this drill bit is engineered to provide reliable durability and consistent cutting performance in fabrication and machining environments.
This drill bit features a 90-degree point angle and 0-degree rake, which helps prevent grabbing and chipping when drilling plastics such as acrylic, polycarbonate, PVC, and other plastic sheet materials commonly used in sign fabrication and plastic processing. The geometry of the bit is designed to produce cleaner holes while reducing stress on brittle plastic materials.
The drill bit includes a straight shank design, allowing compatibility with most standard drill chucks and drill presses used in fabrication shops and machining environments. On larger bit sizes such as 7/16" and 1/2", the shank is reduced to 3/8" to maintain compatibility with standard tooling, while smaller sizes maintain a shank equal to the bit diameter.
This type of drill bit is commonly used in plastic fabrication, sign production, acrylic drilling, and general shop machining applications where controlled drilling and clean hole finishes are required.
