5-Step Straight Shank Titanium-Coated Step Drill

Product Features：

Bearing steel is commonly used to drill chamfered holes in a single pass on thin sheets (such as steel plates and aluminum alloy plates), reducing burrs and completing the task in one step. Bearing steel has a high matrix hardness, while high-speed steel is suitable for hardness below 25, such as carbon steel and thin iron plates.
