Description of π§ Hymnorq Metric Titanium Plastic Aluminum: The Ultimate Precision Tool
50PC BITS SET - The package includes 50pcs of small twist drill bits in metric size (by diameter). 1mm x 10pcs, 1.5mm x 10pcs, 2mm x 10pcs, 2.5mm x 10pcs, 3mm x 10pcs. No need to worry about break one or two bits by accident. HIGH SPEED STEEL - Made of high-quality high-speed steel 4341 for durability and cutting efficiency. Coated with titanium for rust prevention. PRECISION GROUND - These bits are fully ground so that their cutting diameters are seriously accurate. The lifespan is prolonged in comparison to non-ground alternatives(roll forged bits). A smooth bit surface allows for nice clean holes. FOR GENERAL USE - Classic twist flute, designed for general drilling in plastic, wood and soft metals like aluminum, iron, etc. It has a cylindrical shank system (shank equal to drill bit diameter) and is intended for use with collets, which can provide a stronger hold on small bits than a standard lathe chuck. POINT ANGLE ANGLE - The 3mm bit is 135-degree split pointed and the other smaller ones are 118-degree pointed.
