![]() Charts for the allowed range of pitch, major and minor diameters for classes 6H and 6g.Formulas that were used to construct the charts.Recommended Tolerance classes - Charts per tolerance quality and length of engagement.Tolerance fields Charts - Per diameter and pitch.Normal Length of Engagement Chart - Per diameter and pitch.You can measure 1/16″ to 1/2″ range of drill bits using that gauge. As for me I use this gauge to quickly identify the drill bit size in inches and millimeters. You can see fractions, inches, and mm values for each drill bit size here. Drill Bit Size Chartīy following the above method, this table has been prepared with available drill bit sizes. The below table will introduce you to the fractions and decimals of the inches with mm. So we have to interchange the metric units and imperial units. Inches are really popular in the USA but, beyond that, mostly used SI units. You can multiply by 25.4 of inches value when you convert that to mm.Įx – 0.5 inches = 1/2″ = 0.5 inches × 25.4 = 12.7mm When you measure drill bit size in inches, you can convert it into mm using this method. Hence measure it as much as possible accuracy. Practically, you may not be able to measure the drill bit diameter more than 2 decimal places. You can check fraction and decimal conversion using the below table. When drill bit diameter size is available in mm it can convert into inches easily. When you use this you have to convert each with different units types. Drill bit diameter is the most important factor in the drilling process and it should know precisely as much as possible to sharpen or tolerate the diameter.Īll over the world, one of the metric or imperial units is used as the general unit. Most are measured by the metric units and in the USA it’s imperial units. Drill bits are available in different materials, lengths, and diameters.
