<p>Much more hardness - M35 HSS is harder than HSS 4241, suitable for drilling stainless steel plates and steel plates, iron plates, aluminum plates and wood.</p> <p> </p> <p>Good Design: Hex shank fits power tool chuck securely and eliminates slippage. The two flute design removes chips faster and allows particles to escape easily.</p> <p> </p> <p>The split tip increases speed. It can automatically deburr the holes while drilling to keep the drill bit clean.</p> <p> </p> <p>You can use water to cool it when it is working, and it can be used even longer.</p> <p> A Necessity for the Family, DIYers or Professionals - Perfect for home repairs and light duty jobs such as drilling holes in plastic, aluminum, copper and many other types of sheet metal, especially for stainless steel plates and hardened steel plates.</p> <p> </p> <p>Mengshen M35 Cobalt Step Drill Bit is made of high-speed steel with cobalt, which lasts the bit for a long service life. </p> <p> </p> <p> </p> <p> </p> <p>Features:</p> <p> </p> <p> </p> <p>1. M35 high speed steel for longer life;</p> <p> </p> <p> </p> <p>2. Hex shank prevents slippage in the drill chuck;</p> <p> </p> <p> </p> <p>3. Double cutting blades design allows faster and smoother cutting;</p> <p> </p> <p> </p> <p>4. Advanced double spiral flute design outperforms straight flute design and extends bit life. The split-point tip increases speed, and they also include laser-etched measurements to increase footstep visibility.</p> <p> </p> <p> </p> <p>5. The sharpness easily ensures cutting through most sheet metal, plastic and other materials with ease, especially for stainless steel plate and tempering steel plate.</p> <p> </p> <p> </p> <p> </p> <p> </p> <p>Features:</p> <p> </p> <p> </p> <p>Material: M35 HSS</p> <p> </p> <p> </p> <p>Step Drill Sizes:</p> <p> </p> <p> </p> <p>4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm.</p> <p> </p> <p> </p> <p> </p> <p> </p> <p>Contents:</p> <p> < p></p> <p> </p> <p>1 HSS M35 drill bit.</p> <p>Note: The data are all manual measurement, please allow 1-3cm error, due to the difference of light and d display, there will be some color difference, depending on the physical object received.</p>
