When drilling thin plates for T201 JIS Hand Tap Metric Coarse Thread Series, the workpiece should be reinforced. When drilling large workpieces, please ensure the stability of the workpiece. When drilling steel parts, please ensure sufficient cooling and use metal cutting fluid. Good drill rod rigidity and guide rail clearance can improve the accuracy of drilling and the life of the drill bit. Please ensure the flatness and cleanliness between the magnetic seat and the workpiece. At the beginning and end of drilling, the feed rate should be reduced by 1/3. For materials with a large amount of small powder during drilling, such as cast iron, cast copper, etc., compressed air can be used to assist in chip removal without using coolant to ensure smooth chip removal.

Due to structural reasons, the leading angle of NPT thread standard is large at the outer edge and gradually decreases towards the middle. The transverse edge has a negative leading angle, which exerts a squeezing effect during drilling. In order to change the cutting performance of gas tap, the cutting parts can be ground into various shapes according to the properties of the processed material.

The difference between T201 JIS Hand tap Metric Coarse Thread Series is that generally, taper shank Fried Dough Twists drills are used for those with a diameter of more than 13mm, and straight shank drills are used for those with a diameter of less than 13mm. The main reason is that convenient clamping and sufficient clamping force should be considered. It is obviously uneconomical to make small drills into cones, so they should be made into straight shank drills.

Both types of drill bits must be equipped with a rocker arm drill, and a complete set of Mohs drill sleeves is required. The chuck can be 0-13 or 2-16. If you cannot drill holes below 1mm, it is better to use a 2-16 drill chuck, which should have a dedicated wrench. In addition, a Mohs cone sleeve should be equipped with a cone iron, but this item is usually self-made.
