1.45mm Carbide Steel PCB CNC Jewelry Micro Engraving Drill Bit

The SS coating on these drill bits is harder than a TiCN coating and withstands high temperatures. It protects the bits from abrasion and wears when drilling steel, stainless steel, and heat-resistant alloys. Carbide micro drill bits provide excellent hardness, wear resistance, and heat resistance. They create precise holes with a smooth finish and often eliminate the need for reaming the hole after drilling. Carbide bits require a rigid setup such as a fixed-spindle machine. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece.Features Of 1.45mm Tip Spiral Flute Tungsten Carbide Micro PCB Drill Bits: It has a large scrap of discharge space, little resistance. Smooth during the scraps discharge. Use high-quality materials and grinding process makes a bit more sharp cutting edge Reduce cutting force and broken drill, improve the quality of the hole wall. Carbide rods and tungsten steel rods, with high hardness, high wear resistance, high strength, resistance to bending, anti-impairment and long tool life. Range of processing: PCB, SMT, the CNC, mold, plastic, copper, stainless steel, and other precision metal parts processing. Drill bit chip evacuation space large, chip evacuation resistance small, chip removal smooth. In favor of efficient cutting, avoid offsetting drilling.
