## Description

[About us]We are a manufacturer-direct brand. For years, we have been manufacturing for world-class brands and stand behind the scene. Now, we are finally able to connect with the end consumers directly. At Jerax tools, we want to create the best value for the clients by providing premium and cost-effective tools.These M2 Step Drill Bits (Unibit) outperform the average HSS bits on the market. Besides the 5 "Features & Details" listed, below are the additional features that make us different.1. [Optimized Split point Tip]: Self-starting and non-walking. Unlike the common 135 degrees, our angle is specially optimized to be a little sharper which helps grab the material immediately. However, if without our overall good construction and material, a sharper angle would lead to a short life.2. [Optimized Spiral Flute Design]: Spiral flutes guide the debris out faster by its nature, making the drilling much smoother and creating fewer burrs for the holes. The Straight flutes are less effective and require more push. But why the Spiral Flute design is not so popular? Mostly because most companies are not doing it right. Good spiral design requires good material, high accuracy CNC processing, and optimized design details. Spiral Flute design delivers the debris faster but it also has longer blades and contacts more area causing more resistance. We optimized the cutting angle so it can cut at the same resistance as the straight groove design while enjoying the benefits of Spiral (smoother, more consistent, faster and cleaner). Its advantage is more obvious on thick materials. Once you've tried our spiral design, there's no way back to the straight design.[Tips]1. Drilling at low speed (300RPM recommended).2. Using cutting fluid will help the step bits last longer.3. Point the Step bit straight down. Do not angle the bit to cut on the material.[WARNING] Always wear proper Personal Protection Equipments during the use, includ
