2. Craft & Performance
The 6pc Imperial Step Drill Bit adopts premium high-speed steel as the base material, covered with uniform titanium coating to boost surface hardness and anti-rust capacity. Each step cutting edge of the 6pc Imperial Step Drill Bit undergoes precise CNC grinding processing, forming sharp spiral cutting edges that remove metal chips rapidly without dragging or scratching workpiece surfaces. The gradient stepped design of the 6pc Imperial Step Drill Bit integrates multiple drilling diameters into one single bit, replacing dozens of separate drill bits and greatly saving tool storage space. The black oxide treatment on the drill body of the 6pc Imperial Step Drill Bit effectively reduces friction heat during high-speed drilling, preventing premature bit burning and extending service life. The hexagonal shank of the 6pc Imperial Step Drill Bit locks tightly with drill chucks, eliminating slipping during heavy-load drilling operations. The matched center punch works perfectly with the 6pc Imperial Step Drill Bit, pre-punching positioning indentations to stop drill bit wandering at the start of every hole-drilling task. The aluminum storage case customized for the 6pc Imperial Step Drill Bit features shockproof corner protection and metal lock buckle, avoiding collision damage during transportation and daily storage of the 6pc Imperial Step Drill Bit.
