Tungsten carbide crude steel shank drill set shank drill bit micro drill trails, strap case special drill bit micro trails special twist, micro alloy drill paths, trails carbide micro drills, high-precision micro trails alloy drill, drill circuit board dedicated crude shank drill (PCB drill) Material: Carbide Category: Large diameter shank twist: 0.5 (mm) /0.9 /1.0/ 1.2 /1.5 2.0 mainly for small hole processing, commonly diameter of 0.25 to 2.0, knife D3.175mm full-length shank diameter: 38.1MM micro drill paths for the main features: Main mainly for the aerospace industry, and a variety of electronic products industries such as: mobile phones, tablet PCs, stainless steel strap, precision electronic measuring equipment, medical equipment, etc. manufacturing industry, in the processing of difficult materials given shank drill features are: 1. Drill a large chip space: chip resistance of small, smooth chip removal, drilling small heat, reduce smear. 2. extraordinary cutting edge sharpness: As a result of nanotechnology and advanced grinding technology, bit more sharp cutting edge than before, can reduce the cutting force, reduce the broken drill rate, improve the hole wall quality. 3. Based on customer application design tool: Drill rich varieties, to meet different application requirements. Drill all the parameters, such as drill core thickness, taper, etc., are well-designed, effective obvious. The cutting edge strictly symmetrical: beneficial and efficient cutting, avoid offset drilling. 5. Long tool life: Under normal operating conditions, depending on the circuit board and the number of stacked plates, the average number of each drilling from 2000 to 3000 approximately.
