Wear-Resistant Step Drill Bit for Metal, Stainless Steel, Aluminum, Plastic

The EZARC M35 AlTiN Coating Step Drill Bit is a versatile and high-performance tool designed for cutting through a variety of metal materials. With its innovative features and advanced coating, this step drill bit offers exceptional hardness, thermal properties, and resistance to heat, wear, and corrosion.

The step drill bit features a C-curve edge design, which enhances stability and effectively addresses issues of deviation during the cutting process. The triple-flute design further contributes to the overall stability and efficiency of the tool. The M35 cobalt high-speed steel construction provides high levels of hardness and wear resistance, making it suitable for cutting through harder materials such as mild steel, medium-hardness steel, and stainless steel.

The AlTiN coating, rated at 89 HRC, is a crucial aspect of this step drill bit. This coating offers exceptional hardness and thermal properties, providing superior resistance to heat, wear, and corrosion. Laboratory tests have shown the AlTiN coating to be more durable than steamed black oxide coatings, resulting in a longer bit life.

The step drill bit is designed with nine distinct steps, offering seamless and effective drilling across various thicknesses, eliminating the need for multiple bits. The step sizes included are 1/4", 5/16", 3/8", 7/16", 1/2", 9/16", 5/8", 11/16", and 3/4".

When using the EZARC M35 AlTiN Coating Step Drill Bit, it is recommended to ensure the chuck is securely tightened on the power tool and to use low speed and light pressure on the workpiece until reaching the desired depth. Lubrication of the cutting edge with oil or a water-soluble lubricant is also advised to reduce friction, heat, and debris.

The step drill bit is suitable for cutting through metal sheets up to 1/8" (3mm) thick and stainless steel sheets up to 1mm thick. To maintain the drill bit in top condition, users are advised to add cutting oil or spray water to cool it during continuous use, as the start-up speed may be slower due to the larger cutting angle.

In summary, the EZARC M35 AlTiN Coating Step Drill Bit is a versatile and high-performing tool that can effectively cut through a wide range of metal materials, including aluminum, brass, copper, cast iron, galvanized pipe, stainless steel, and low-carbon steel. Its innovative features and advanced coating make it a reliable choice for various metalworking applications.
