So, to ensure you invest in the best drill bits, below are some of the features you might need to consider. Drill Bit Material

Tungsten carbide drill bits, on the other hand, offer an increased level of hardness and resistance compared to steel bits. HSS is an acronym for High-Speed Steel. The properties which make HSS Drill Bits an ideal choice to drill acrylic are their suitability for harder materials such as metal, wood, and acrylic, as well as their ability to withstand the heat generated from fast-speed operation. HSS Drill Bits are superior to ordinary carbide drill bits and can last for at least 150 holes and to a maximum of 450 before they become too worn to function effectively.

Additionally, it’s worth pointing out that each plastic drill bit is equipped with wider blade angles. This ensures you get precise and more stable drilling. The fly cutter and cutting tool itself must be secured properly. Cutting tool must only be extended enough to achieve the desired depth of cut.

The great thing about ceramic coated bits is that they don’t heat up in the same manner as other bits, due to the nature of the ceramic bit. They are also long-lasting. The ceramic bit also has flute-like cuts, which help the bit to shave off the product. You can find the ceramic bits in several grids such as medium coarse and fine course. Ceramic bits can also be cleaned and sterilized. Several drill bit geometries are described below that can be used with success, although most do not leave the inside diameter of the hole with a smooth finish. These bits require the same considerations for support behind the sheet and for cooling as previously reviewed for twist drills bits. By keeping on the film we include in all of our acrylic sheets for sale, you reduce the possibility of creating avoidable scratches on the surface of the acrylic. If you do create scratches on your acrylic, don’t panic! Because we’ve also written a guide which covers how to remove them! Air or liquid coolants should be used whenever possible. Coolants reduce generated heat, and therefore improve hole quality. In certain hole depths and sizes, coolants are necessary to prevent melting. As a general rule, coolants should be used when the depth of the hole (H) exceeds bit diameter (D) (e.g. for D=0.250", a coolant should be used for H>0.250"). Coolants should also be used for holes greater than or equal to 1/2" in diameter (D ≥1/2").

Brad Point Bit (1/8" to 1") - this design is similar to a twist drill with a modified tip similar to a spade bit with spurs. It has an advantage over a spade bit because it has a helical flute design which will pull out chips. IPR (inches per revolution) - the amount of IPR material being removed per revolution of the drill bit, also referred to as chip load. The SFM and IPR cannot be directly set on manually operated drilling equipment. However, SFM and IPR data can be used to determine proper settings for spindle rotation speed in RPM (revolutions per minute), and feed rate in IPM (inches per minute). If the optimum SFM and IPR are known, then the settings can be determined using the following equations: ACRYLITE® sheet is a combustible thermoplastic. Precautions should be taken to protect this material from flames and high heat sources. ACRYLITE® sheet usually burns rapidly to completion if not extinguished. The products of combustion, if sufficient air is present, are carbon dioxide and water. However, in many fires sufficient air will not be available and toxic carbon monoxide will be formed, as it will when other common combustible materials are burned. We urge good judgement in the use of this versatile material and recommend that building codes be followed carefully to assure it is used properly. Always a trusted name in the power equipment, this CRL drill bit is made with quality in mind. Simply put, it is manufactured from high-quality steel to provide better longevity and protection from wear.
