WebMay 30, 2024 · The different bit sizes usable with a single collet carry a 0.5mm range for small bits, a 1mm range for mid-size bits and a 2mm range for larger bits. For example, an E-8 collet can hold bits between 7.5-8mm in diameter but an E-50 can hold bits between 48-50mm in size. Also Read: Different Types Of Mig Welding. Engineering fits are generally used as part of geometric dimensioning and tolerancing when a part or assembly is designed. In engineering terms, the "fit" is the clearance between two mating parts, and the size of this clearance determines whether the parts can, at one end of the spectrum, move or rotate independently from each other or, at the other end, are temporarily or permanently joined. Engineering fits are generally described as a "shaft and hole" pairing, but are not necess…

With engineering fits, the tolerance will always be shown in an alpha-numeric code. For example, a hole tolerance may be H7. The capital letter signifies that we are dealing with a hole. When indicating tolerance for a shaft, the letter will be lowercase. The number shows the international tolerance grade (ISO 286).
