Recommended taps to cut magnesium alloy

【英】困ったときの知恵袋詳細
Cutting Taps How to use
We received an order for digital camera parts processing. The material is a magnesium alloy. Please tell me which tap should be used on this material. Most of the sizes are M3 or less, and some are smaller than M2. Most of the screw threads are blind holes with a small difference between the pilot hole length and the screw effective length. In this situation, the tap needs to go as close as possible to the bottom of the hole.
Magnesium alloy is a material that is relatively easy to cut. You have stated the blind holes are close to the bottom of the hole, so a spiral tap "AL-SP 1.5P" for aluminum material is generally recommended for magnesium. However, if you need a tap less than a M2 thread or if you need to tap with a chamfer of 1.5P or less, the following short chamfer hand tap for magnesium alloy castings: MG-HT is the recommended tap.
