Migiwata Jobber Length Twist Drill Review

60PC BITS SET - The package includes 60pcs of small twist drill bits in inch size (by diameter). 3/64 inch x 10pcs, 1/16 inch x 10pcs, 5/64 inch x 10pcs, 3/32 inch x 10pcs, 7/64 inch x 10pcs, 1/8 inch 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 1/8" bit is 135-degree split pointed and the other smaller ones are 118-degree chisel pointed.
