High-speed steel (HSS) bits are versatile and work well with most drills, while cobalt bits offer greater heat resistance and are suitable for tougher materials. Understanding the requirements of your specific drilling task will help you select the best drill bit for the job at hand.
How To Measure Drill Bit Sizes
To measure drill bit sizes accurately, you’ll need a drill bit gauge or a set of drill bits with marked sizes. Using a ruler or caliper, measure the diameter of the shank for non-tapered bits or the widest part of the tip for tapered bits. Ensure the measuring instrument is aligned parallel to the bit to get an accurate reading.
For twist drill bits, locate the number or letter stamped on the bit or on the bit’s case. The number or letter represents the bit’s size, and referencing a drill size chart can help you identify the corresponding dimensions. For hole saws, measure the diameter of the central pilot bit or the width of the hole saw to determine the size. Alternatively, use a drill bit gauge with labeled holes to check and confirm the drill bit’s size.
It’s crucial to handle the measuring instruments carefully for precision. Keeping the tools clean and free from debris will enhance the accuracy of your measurements, ultimately helping you find the right fit for your drilling needs.
